James M. Shwayder, MD, JD

A 19-year-old G1P0 was seen for her initial obstetrical visit by a certified nurse-midwife (CNM) at 9 weeks, 2 days by dates. Her exam revealed a height of 5’1”, weight of 141 lb, with a body mass index of 26.6 kg/m². Her exam revealed a gynaecoid pelvis, with a diagonal conjugate >11.5 cm, which was felt to be “adequate.”

He is a graduate of the University of Denver College of Law and is a nationally and internationally recognized expert in gynecology ultrasound and minimally invasive surgery. 

He actively consults on legal matters in medicine, including liability in ultrasound and gynecologic surgery, as well as issues surrounding privileging and insurance fraud.

The patient underwent an ultrasound at 13 weeks, 2 days, which confirmed her dates, with a subsequent ultrasound at 22 weeks, 1 day, consistent with the previous study and with appropriate interval fetal growth. The patient had an uncomplicated pregnancy.

The patient presented to the hospital at 39 weeks, 2 days with irregular contractions. She was evaluated by the CNM at 3 a.m. with her cervix being 1.5-cm dilated, 50% effaced, with a vertex at a -2 station. She was felt to be in early labor, with the fetal heart rate (FHR) in the 140s, with good variability (a Category 1). 

For context, the hospital is a private academic hospital with an ob/gyn residency, and a full-time CNM service, which works collaboratively with the residents and the attending physicians. The CNMs are hospital employees who deliver patients in a birthing unit located in Labor and Delivery.

Despite being in very early labor, the patient did not feel comfortable going home. Thus, she was allowed to rest throughout the night. 

A re-examination at 7:45 a.m. revealed a cervix being 2.5 cm dilated, 100% effaced, a vertex at a -2 station, with a bulging bag of water (BBOW). The estimated fetal weight (EFW) was 7 lb 2 oz. There was a Category 1 FHR tracing. The patient was allowed to ambulate throughout the morning, with periodic FHR monitoring confirming a continued Category 1 tracing. At 11:30 a.m., her cervix was 3-cm dilated, 100% effaced, a vertex at a -1 station, with a BBOW.

A Category 1 tracing documented contractions every 5 to 7 minutes of mild to moderate strength. At 3 p.m., there was no change in the patient’s examination. 

Thus, membranes were ruptured, noting clear fluid. At 5 p.m., the cervix was 4- to 5-cm dilated, 100% effaced, with a vertex at a -2 station. Contractions were every 2 to 5 minutes of moderate strength.

., the cervix was 5-cm dilated, 100% effaced, with the vertex at a -1 station, in a left occiput posterior (LOP) position. Contractions were every 2 to 6 minutes of moderate strength, lasting 60 seconds. There was a Category 1 tracing. At 7:15 p.m., her exam remained unchanged. A continuous lumbar epidural was placed.

At 8 p.m., her cervix was 5- to 6-cm dilated, 100% effaced, the vertex was at a -1 station, with caput at a 0 station. It was elected to augment labor with oxytocin. An intrauterine pressure catheter was placed. 

, the cervix was 6-cm dilated, 100% effaced, with the vertex at a -1 station, in a LOP position. There were occasional mild variable decelerations, with the baseline FHR in the 140s. The oxytocin was increased to 8 mU/minute, with occasional coupling and tripling. 

At 11 p.m., the cervix was 6 to 7 cm, with the vertex at a -1 station, 100% effaced, in a persistent LOP position. The FHR was in the 170s. The patient’s temperature was 101.4º F. The CNM consulted with the chief resident (R4), who consulted with the attending physician. It was elected to begin antibiotics and acetaminophen, with a diagnosis of chorioamnionitis. At 1:20 a.m., the cervix was 7-cm dilated, 100% effaced, with the vertex at a 0 station. The contractions were irregular with occasional variables. 

The attending physician’s note at 1:30 a.m. indicated that they would proceed with a cesarean delivery if there were repetitive late decelerations or there was no progress in the next 2 hours. At 3:45 a.m., the R4 examined the patient with the CNM. The patient’s cervix was 7-cm dilated, 80% effaced, at a 0 station. It was elected to recheck the patient in 2 hours, at which time the cervix was 8-cm dilated, 100% effaced, at a 0 station. 

, a new CNM assumed care of the patient. Her exam revealed the cervix being 8- to 9-cm dilated, 100% effaced, with molding to a +1 station. The EFW was 8.5 lb. The oxytocin was at 30 mU/min. The documented diagnosis was “Protracted active phase. Consult MD at 9 a.m.” 

., there were two episodes of prolonged decelerations, the lowest being to the 60s for 4 minutes, returning to the 120s and upward to the 140s. A fetal scalp electrode was placed. 

At 7:57 a.m., the previous R4 and a new attending physician evaluated the patient. Oxygen was placed via nasal cannula at 10 L/minute. At 8 a.m., the R4 and attending physician were called to the room when the FHR had spontaneous decelerations to the 70s and 80s for 4 to 5 minutes. The oxytocin was turned off. The attending physician discussed a cesarean delivery with the patient. There was good documentation of the risks of surgery and options in management.

., a male infant was delivered, weighing 7 lb 9 oz, with Apgar scores of 9 and 9, at 1 and 5 minutes, respectively.

Umbilical cord gases were obtained with the following results:

Arterial=7.30 (Normal = 7.18-7.38);
PCO² = 43 mmHg
(Normal = 32-66 mmHg);
HCO³ <40
(Normal = 17-27 mmol/L);
Base excess = -5.7
(Normal -8 to 0 mmol/L)

 = 31 mmHg;
HCO³ <40; Base excess = -4.9

The placenta was delivered manually at 9:21 a.m., with oxytocin administered shortly thereafter.

Methylergonovine, 0.2 mg IM, was administered at 9:23 a.m. due to excessive bleeding. With continued bleeding, misoprostol, 800 mcg, was placed rectally at 9:34 a.m. At 9:40 a.m., carboprost, 0.25 mg, was administered, as the patient’s bleeding was not responsive to the prior medications. 

, a “Code White” was called as a general alert for excessive bleeding, which brought additional resources and personnel to the operating suite. Surgical maneuvers performed included a B-Lynch suture and O’Leary stitches. They considered and rejected uterine artery embolization. An attempt was made to place an intrauterine compression balloon, which was unsuccessful. 

, the attending decided to perform a hysterectomy. A second opinion was provided by the department chair. A supracervical hysterectomy was performed without complication. The procedure, which was completed at 11:49 a.m., had an estimated blood loss of 3000 mL, and 4200 mL of crystalloid fluids was administered intraoperatively. 

Blood product replacement included 6 units of packed red blood cells, 4 units of fresh frozen plasma, with 1 unit of apheresis platelets. It was noted that labs sent at 11:04 a.m. revealed early disseminated intravascular coagulation (DIC).

Pertinent labs included a hemoglobin and hematocrit with the following levels:

The baby had a normal hospital and neonatal course. The patient had an uncomplicated postoperative and postpartum course. 

Of note, the anesthesiologist, while evaluating the patient on the day following surgery, documented the following, “She expressed confidence that proper decisions were made, and she is grateful for her life and her baby.”

Two years later, the patient filed a suit against the physicians and the hospital for an unnecessary hysterectomy following her cesarean delivery. As a result, the patient and her husband have suffered significant pain and suffering. 

After discovery, the case proceeded to trial. The plaintiff’s maternal-fetal medicine (MFM) expert opined that there were remarkable changes in the FHR, with fetal tachycardia, decreased beat-to-beat variability, and intermittent decelerations. Further, there was abnormal progress in labor, with a failure to descend. As such, the patient should have been delivered by a cesarean at 3:30 a.m. 

In addition, due to poor communication, there was a lack of personal involvement of the attending physician in managing the patient, which led to a delay in performing the cesarean delivery. 

The delay, with the resultant uterine atony, resulted in the need for a hysterectomy. Uterine atony was predictable, as the patient had been on oxytocin for more than 12 hours and she had chorioamnionitis. The expert quoted literature stating that 71% of such patients experience atony. 

Thus, the patient should have been appropriately counseled preoperatively about the need for a hysterectomy. As a result of the unnecessary hysterectomy, the patient will not be able to have further children.

The defense’s MFM expert testified that the record reflected ongoing, timely, and appropriate evaluation and communication regarding the patient’s status by the CNMs, the chief resident, and the attending physicians. 

He further testified that the collaboration among these care providers was well within the standard of care required in the setting of a delivery primarily managed by a CNM and met all applicable hospital protocols. Oxytocin was appropriately and timely initiated and was appropriately monitored and adjusted throughout the labor. He testified that the signs and symptoms of chorioamnionitis were timely and appropriately recognized and treated. 

Chorioamnionitis can lead to a protracted labor, which, with generally reassuring maternal and fetal status, does not compel an earlier cesarean delivery. In addition, an occiput posterior position can lead to a desultory labor. However, with no evidence of fetal macrosomia, pursuing a vaginal delivery was appropriate. 

In addition, despite being desultory, the patient did not meet the American College of Obstetricians and Gynecologists’ definition for an arrest of labor in the first stage, which requires either 4 or more hours of adequate contractions, or at least 6 hours of inadequate contractions, and no cervical change. He further testified that there is no literature to support the contention that an earlier cesarean would have prevented the ultimate need for hysterectomy.

After 4 hours of deliberation, the jury returned a defense verdict.

This case presented a unique dynamic, with CNMs providing the primary management of the patient. In contrast to a separate birthing center, this hospital had established a birthing unit in Labor and Delivery, allowing CNMs to manage patients with immediate physician consultation if needed. 

The hospital had established protocols with guidelines for CNM consultation with a senior resident or the attending physician. This patient’s management complied with these protocols. Of note, some departments are reluctant to have such protocols, fearful that they will be used against physicians in the event of a malpractice suit. 

Although deviations from protocols, without appropriate documentation, can place providers at risk, deviations with documented reasoning are quite defensible. However, as in this case, following protocols enhances the defense of a case.

Documentation of the rationale for various interventions, e.g. oxytocin augmentation and antibiotic treatment, resident and attending involvement, and surgical counseling, was excellent. Such documentation enhances case defensibility. Oxytocin use is often present in obstetrical malpractice actions. 

Thus, clear documentation regarding the decision to use oxytocin, as well as carefully documented monitoring is critical. Although the patient initially expressed that she was satisfied with her care, the realization that she could have no further children naturally resulted in her questioning her prior care. Being sensitive to such concerns and addressing them during future appointments can often allay a patient’s misgivings. Studies support that good communication with the patient is one of the best ways to avert litigation.

This case presents a unique dynamic involving certified nurse midwives; following protocols enhanced defensibility.

Cesarean delivery leads to unexpected outcome

A 39-year-old G2P1102 presented to her gynecologist with a complaint of pelvic pressure. She had regular menses and no loss of urine. Her history was significant only for a postpartum bilateral tubal ligation 2 years earlier.

The woman’s examination revealed prolapse of the uterus, with the cervix visible at the introitus. An ultrasound performed by the physician 1 week after her initial presentation revealed a 4.8 4.5 6.8-cm left ovarian cyst. The physician recommended a laparoscopically assisted vaginal hysterectomy (LAVH) and left salpingo-oophorectomy (SP). 

The woman was presented with several options for management, including a total abdominal hysterectomy and left salpingo-oophorectomy. The gynecologist reviewed the risks of surgery and potential complications. All the patient’s questions were answered and operative permissions were signed. 

The surgery was scheduled for 1 week later. 

During surgery, insertion of the Veress needle was without incident. However, upon insertion of the umbilical trocar, profuse bleeding was noted and the patient became bradycardic and hypotensive and experienced cardiac arrest. 

She was resuscitated, following which, the gynecologist made a midline vertical incision and noted a laceration in the area of the aorta. A general surgeon was consulted, who could not fully control the bleeding. Thus, pressure was applied to the aorta and the patient was transferred to a tertiary hospital 40 minutes away that had a vascular surgeon.

Upon arrival at the tertiary hospital, the patient was taken immediately to surgery. The vascular surgeon noted transaction of the anterior wall of the common iliac artery encompassing almost half the diameter of the artery. Also noted was a duodenal serosal tear, presumably from the pressure held during transport. 

The vascular surgeon also noted thrombi of the common iliac artery, and the right and left iliac arteries. The surgeon repaired the vascular injury with an end-to-end anastomosis, and performed right and left iliofemoral thrombectomies, as well as from the common iliac artery, restoring flow to the right and left common iliac arteries. He then noted that both the patient’s feet had good capillary refill. 

The duodenal laceration was repaired without consequence. The patient had a relatively uncomplicated recovery, with the exception of residual neuropathy in her right leg and hip, with foot drop that persisted despite months of occupational and physical therapy.

Approximately 9 months after the attempted LAVH, the patient sought the care of another gynecologist, who noted that her uterus was protruding to the introitus with valsalva. 

An ultrasound was obtained, which was interpreted as normal, with no pelvic or ovarian masses or cysts. The physician recommended a total vaginal hysterectomy. Despite being “scared to death,” the patient elected to go forward with the procedure, which was performed without incident. Surgical findings stated that “both tubes and ovaries appeared normal.”

Ultimately, the patient filed suit against the original gynecologist, alleging inadequate and inappropriate preoperative evaluation, improperly performed surgery, with resultant complications, long-term physical deficits, pain and suffering, and loss of life’s enjoyment.

Deposition of the defendant gynecologist revealed several potential concerns. 

When questioned if it would be an option to wait and see if the cyst would go away on its own, the gynecologist stated, “I would not consider that to be an option in this case. I was trained that anything over 5 cm is a problem.”

During questioning about the performance of the surgery, the gynecologist described a closed-entry technique, using a Veress needle. A saline-drop test was used to confirm intraperitoneal placement of the Veress needle. 

The opening pressure was 7 mmHg. To establish the pneumoperitoneum, the abdomen was insufflated with 2 L of CO2. When questioned if the surgeon insufflates to a particular pressure, for example 15 or 20 mmHg, the gynecologist replied that he does not use a pressure cut off. His reasoning was that “nobody is ever totally relaxed.”

Following establishment of the pneumoperitoneum, the patient was placed in Trendelenburg, her abdomen was elevated with the surgeon’s hand, and the trocar was inserted at a 45º angle into the pelvis. The gynecologist suspected that the vascular injury occurred with insertion of the trocar.

In reviewing the gynecologist’s surgical experience, he stated that he had performed thousands of laparoscopies and had assisted on or performed LAVHs since 1990. It was noted that the physician had completed his residency in 1984. 

Unfortunately, he could not document any formal continuing education courses, nor additional training or education in ultrasound or more advanced laparoscopy since that time. The physician was board-certified and was current with his maintenance of certification.

The plaintiff’s ultrasound expert reviewed the original ultrasound images and noted a 6.80 4.86 4.49-cm simple, unilocular cyst, consistent with a persistent follicular cyst or a serous cyst. 

This expert opined that the current recommendation for follow-up of such a cyst in reproductive-aged women is a repeat ultrasound in 2 to 6 months. Thus, immediate intervention was not indicated. Subsequently, prior to the TVH, an ultrasound revealed that the cyst had completely resolved, confirming that surgical intervention for the ovarian cyst was not required. 

Thus, one could have avoided the risk of laparoscopy altogether, particularly with the primary surgical indication of uterine prolapse.

The plaintiff’s laparoscopy expert noted several breeches in the standard of care. Although a closed-entry technique, and even a direct-insertion technique without a pneumoperitoneum, is an acceptable alternative, the method the defendant described was not within the standard of care. Insufflating a specific amount of CO2, for example 2 L, is not adequate. 

Contrary to the defendant’s statement, patients are paralyzed for the procedure, and thus, they are totally relaxed. One cannot assume that 2 L of CO2 provides an adequate pneumoperitoneum in all patients. Thus, current practice is to infuse enough CO2 to establish an intraperitoneal pressure of 12 to 15 mmHg prior to insertion of the primary trocar. 

In fact, many surgeons insufflate to a pressure of 20 mmHg for initial trocar insertion, reducing this pressure to 12 to 15 mmHg for placement of the secondary trocars. Inadequate intraperitoneal distension subjects the patient to a greater risk of vascular injury, as occurred in this case. 

The placement of a patient in Trendelenburg for insertion of the umbilical trocar is not currently recommended. The Trendelenburg position places the aorta and the common iliac vessels in direct line with insertion of a trocar at a 45º angle. 

Although this was common practice in the past, current recommendations, literally for several decades, are to maintain the patient in a supine position, with the abdominal wall elevated, for insertion of the umbilical trocar, only changing to the Trendelenburg position for insertion of the secondary trocars. 

The plaintiff’s expert opined that placing the patient in the Trendelenburg position for insertion of the umbilical trocar was a breech of the standard of care. Doing so places the patient at risk for the exact vascular injury encountered in this case.

No criticisms were levied against the care of the general surgeon, the vascular surgeon, or the subsequent postoperative care and rehabilitative services. Thus, the defense focused on the criticisms levied against the preoperative evaluation and the surgical technique.

In evaluating the defensibility of the case, the identified lack of documented continuing education and additional surgical training placed the case defense at risk. Unfortunately, proceeding to trial posed a significant risk of losing the case, with subsequent exorbitant damages. It was elected to settle the case prior to trial for $900,000.

This case highlights the importance of remaining cognizant of current literature and surgical practices. All too often, physicians fail to remain current in the various areas of their practices. 

One would assume that maintenance of certification would allow physicians to stay current in their practice. However, ongoing education in specific practice areas may be required. Ultrasound, a valuable adjunct to our care of patients, is rapidly changing. 

The approach to adnexal masses is constantly evolving, with consensus guidance for management available. In this case, the physician’s lack of awareness of these newer guidelines impacted the preferred management option: observation. If there is any question about diagnosis or management, one can always seek a second opinion from a more experienced sonologist. 

As in this case, this functional cyst resolved, negating the need for an abdominal approach. Thus, the physician could have pursued a vaginal hysterectomy, the preferred route, which was ultimately performed, avoiding the risk of laparoscopy.

The need to adapt one’s surgical techniques is particularly true in the rapidly changing surgical environment of minimally invasive surgery. Changes in accepted techniques were not adopted in the current case. 

With the physician’s lack of documented continuing education and additional surgical training, this case was at greater risk. The cited breeches rendered the case one with a significant risk of losing at trial. Thus, the best perceived option was settlement.

Major vascular injury incurred at laparoscopy

A 21-year-old G2P1001 was admitted on July 28 at 38 weeks, 4 days’ gestation for labor induction for a suspected large for gestational age (LGA) baby. The patient’s original estimated date of deliver was August 22. 

An ultrasound at 19 weeks, 6 days adjusted her date of delivery to August 7. The patient had a normal antepartum course, with normal antenatal screening, and normal glucose screening at 28 weeks’ gestation.

Two years earlier, the patient had given birth to an 8 lb, 10 oz male at term via an uncomplicated vaginal delivery with a three-degree extension.

During the current pregnancy, she was admitted at 33 weeks 0 days for possible preterm labor. Visual exam revealed a friable cervix, with 

. The patient was observed for approximately 21 hours, during which she received a dose of subcutaneous terbutaline, which led to diminished contractions, without significant cervical change. 

She was given a course of steroids and discharged on clindamycin and metronidazole.

On admission for labor induction on July 28, the patient’s diagnosis was advanced cervical dilatation and LGA. The admission history and physical documented a vertex presentation, with a cervix 3-cm dilated, 50% effaced, and a -2 station. The woman’s pelvis was described as “adequate.” 

Documentation did not include an estimated fetal weight (EFW). Induction proceeded with intravaginal prostaglandins, inserted at 7:30 am, with regular contractions beginning approximately 40 minutes thereafter. Fetal heart tones (FHTs) revealed a Type 1 pattern, with a baseline fetal heart rate (FHR) in the 140s. Augmentation of the patient’s labor with oxytocin was begun, at 2 mU/min.

Approximately 4 ½ hours later, at 12:05 p.m., the physician examined the patient. At that time, with oxytocin at 10 mU/min, her contractions were every 1 to 2 minutes, 60- to 70-mmHg in strength, with a continued Type 1 pattern. Her cervix was 4-cm dilated, 50% effaced, at a -2-3 station, with an occiput posterior position. Amniotomy revealed a small amount of clear fluid, and an internal FHR electrode was placed. 

An epidural was placed shortly thereafter. At 1:55 pm, with oxytocin at 12 mU/min, the patient’s cervix was 7- to 8-cm dilated, 90% effaced, at a 0+1 station. FHTs were in the 140s and, despite minimal variability, no decelerations were observed. At 3:45 pm, examination revealed a cervix with an anterior lip. 

No mention was made of the fetal station. The patient began pushing at 4:45 pm. FHTs were stable. The physician remained in the room while the patient pushed. Severe variable decelerations to the 60s started at 5 pm and the head was delivered at 5:10 pm and spontaneously rotated from right occiput posterior to occiput anterior position. The body did not immediately deliver. 

A McRoberts maneuver was used for 2 minutes and various maneuvers were performed to resolve a 6-minute shoulder dystocia. Fundal pressure was applied to assist with delivery of the body, which was accomplished at 5:18 pm. An 11 lb, 12 oz (5335 g) male was delivered with Apgar scores of 1, 6, and 8, at 1, 5, and 10 minutes, respectively. The arterial cord gases were pH = 7.19; pO2 = 23; pCO2 = 60; base excess = -7.0.

Then, and only then, first application of fundal pressure

Also described was an appropriate repair of a three-degree extension.

Subsequently, placental pathology revealed focal, mild, chronic non-specific chorionitis.

The newborn examination revealed bruising of the baby’s ears, face, chest, and right underarm. The right underarm bruising was consistent with traction to the armpit. There was no movement of the left arm. 

 while the pediatrician could not rule out a dislocation of the right shoulder. The left shoulder would have been the anterior shoulder at time of delivery. The baby had a low blood sugar at 37 and required an infusion of dextrox 10% in water.

The baby was transferred to an academic medical center. The admission physical revealed no movement of the left upper or lower arm. Radiologic studies revealed no dislocation of the left or right shoulder. 

revealed avulsion of the nerve roots on the left at C8 to T1, with mild displacement of the cord to the right. There was a possible subarachnoid hemorrhage. A cranial ultrasound was normal. Computed tomography of the head revealed no evidence of intracranial hemorrhage or displacement of the midline sutures. There was swelling on the right side of the face with minor asymmetry of the coronal suture.

A neurology consult confirmed Erb’s palsy, with a significant avulsion injury and complete left brachial plexus palsy. The neurologist opined that other roots may be torn more distally. There was probable right Horner’s syndrome, right torticollis, and a hoarse voice suggestive of laryngeal paresis.

Despite intensive physical therapy, there was no recovery of the function of the left upper extremity over 5 months, associated with mild ptosis of the left eyelid and ipsilateral pupil, consistent with Bernard-Homer Syndrome. 

The baby was referred to a pediatric neurosurgeon at another academic institution and underwent left brachial plexus exploration and external and internal neurolysis approximately 11 months after birth. Nerve grafting was not performed, as intraoperative electrical stimulation of the musculocutaneous nerve produced some visible and palpable contractions of the biceps brachii, and stimulation of the accessory nerve produced a similar response of the left deltoid muscle. 

Six weeks after surgery, the child was able to partially extend the elbow and flex his fingers. 

, there was no flexion at the elbow or extension of the fingers. Neurosurgery follow-up 4 months later (5 months postoperatively) identified no further recovery. The child continues with physical therapy.

Negligence in not offering the patient a primary cesarean delivery

Negligence in management of the shoulder dystocia

Damages including long-term care of the child, required long-term physical and occupational therapy, current and future pain and suffering, loss of future earnings, as well as emotional distress of the parents, and loss of consortium.

Following discovery, the defense elected to proceed with trial, as the case was deemed highly defensible.

At trial, the plaintiff’s experts noted that induction of labor for a LGA baby is not recommended by the American College of Obstetricians and Gynecologists (ACOG). Lack of an estimated fetal weight, either clinically or with ultrasound, was a breach of the standard of care. Had the physician estimated the weight as at least 5000 g, 

a primary cesarean delivery should have been pursued

Even with an estimated fetal weight > 4500 g, the risk of shoulder dystocia is up to 50%. The baby suffered permanent irreversible injuries that will require long-term physical and occupational therapy. The child will never have a normal life.

The defense experts testified that shoulder dystocia cannot be accurately predicted or prevented. None of the risk factors for macrosomia were present in this case, including preexisting diabetes and gestational diabetes, maternal obesity, excessive gestational weight gain, or abnormal antepartum glucose screening. 

The patient’s first baby weighed 8 lb, 10 oz or 3934 g and was delivered vaginal without difficulty. There was no clinical evidence of macrosomia, noting that the fundal height at 38 weeks was 39 cm.

Although an estimated fetal weight was not documented, the obstetrician deemed that the mother’s pelvis was adequate, evidence that there was consideration of the estimated fetal weight. 

Clinical and ultrasound estimates of fetal weight are poor indicators of actual fetal weight. Ultrasound is, at best, accurate to within 10% in estimating weight, and worse with larger babies.

Induction of labor is controversial. Earlier studies show an increased cesarean rate without a significant reduction in shoulder dystocia. Recent studies show induction of labor results in a four times reduction in the rate of shoulder dystocia. 

 even a primary cesarean delivery does not eliminate the risk of birth trauma and neonatal brachial plexus injury associated with macrosomia.

Further, most macrosomic babies do not experience shoulder dystocia. Finally, brachial plexus injuries can occur as a result of intrauterine positioning, not just a result of a shoulder dystocia.

The patient rapidly entered active labor following induction. She did not experience a prolonged labor, a prolonged second stage, nor was operative delivery required. Once the shoulder dystocia was encountered, all maneuvers were appropriate. The shoulder dystocia lasted 6 minutes, which is not an extended time. 

The umbilical cord gases were normal, evidence that the baby did not suffer any hypoxic compromise. The clinician’s contemporaneous documentation was excellent.

During rebuttal, the plaintiff’s experts again criticized the care, particularly the lack of documentation of an estimated fetal weight. If the estimated fetal weight had been less than 5000 g, attempting a vaginal delivery could have been justified. 

However, had the estimated fetal weight been 5000 g or greater, according to ACOG, a primary cesarean delivery should have been performed. The baby weighed 5335 g and thus, a cesarean delivery should have been performed. 

Further, in managing the shoulder dystocia, the documentation states, “the slightest amount of downward traction” was applied. Avulsion of the nerves does not occur without the application of excessive, improperly directed force. Avulsion injuries are not a result of intrauterine positioning. 

The baby has permanent injuries with paralysis of the left arm and distortion of his face, which will result in lack of social acceptance in the future. 

Defense experts testified that ACOG only states that a scheduled cesarean delivery may be beneficial and does not mandate that it be performed. The ACOG recommendations are based on expert opinion, not randomized trials. 

During the reparative surgery, there was evidence of some nerve conduction, thus the current disabilities may still respond to therapy in the future.

After 6 hours of deliberation, the jury found for the plaintiff, awarding $3.5 million.

This case was defensible, except for two major issues

: the lack of a pre-induction estimated fetal weight and the resulting nerve avulsion. The lack of an estimated fetal weight is not uncommon in shoulder dystocia cases resulting in litigation. Even though inaccurate, a clinical or ultrasound-based estimated fetal weight should be included in the initial assessment of all patients, whether for induction or in labor. Documentation of an estimated fetal weight, even if inaccurate, renders cases more defensible. 

Lack of such documentation, as in this case, is a major obstacle to successful defense. Avulsion of the nerve roots on the left at C8 to T1 was an additional impediment to successful defense. Plaintiff attorneys who frequently litigate shoulder dystocia cases often pursue only cases with nerve avulsion, as the forces required to cause avulsion have been shown to exceed the forces associated with the typical maneuvers used to manage shoulder dystocia. 

Further, avulsion injuries rarely recover spontaneously and require early surgical intervention, which if not successful, result in permanent disabilities. 

, the presence of the child in the courtroom throughout the trial was a constant visual reminder of his life-long disabilities.

This case involves induction of labor for a suspected large for gestational
age (LGA) baby in a mother with a normal antepartum course.

Shoulder dystocia: The unpredictable nightmare

A 39-year-old G3P2012 presented to the Emergency Department (ED) with a complaint of 2 weeks of worsening low back and abdominal pain and more recent-onset nausea and vomiting. She had been seen in an urgent care center 4 days earlier with lower back pain, which was treated with naproxen.

Her history included hypertension, which was well-controlled with a single medication, bilateral tubal ligation, subsequent ruptured ectopic pregnancy, and exploratory laparotomy with extensive adhesiolysis, performed for pelvic pain.

The patient was afebrile, with stable vital signs. She had a tender, palpable mass extending into the lower abdomen from the pelvis. Pelvic ultrasound revealed a 14-cm left ovarian cyst with multiple septa and possible hemorrhage. A review of her records revealed a similar-sized mass on an ultrasound performed 5 years earlier. The only laboratory abnormality was an elevated white blood cell (WBC) count of 15,100 cells/µL.

Surgery was pursued on an urgent basis. A laparotomy was performed due to the size of the mass and the extensive adhesions documented on prior laparotomy. A large, cystic pelvic mass was encountered, but it could not be completely removed because of extensive, dense adhesions. Therefore, it was aspirated, returning 750 cc of serosanguinous fluid. A portion of the cyst wall was excised and sent to pathology. A peritoneal drain was placed

On postoperative Day 1, the patient had a temperature of 99.2º F; blood pressure 162/76 mmHg; pulse 108 beats per minute (bpm), and respirations 15 per minute. Her abdomen was soft, with bowel sounds present. The peritoneal drain had a total of 115 cc of serous fluid over 24 hours, with no drainage over the most recent 8 hours.

Urine output since the surgery was 1450 cc. The patient’s hemoglobin and hematocrit were stable at 9.8 g/dL and 29%, respectively, with a WBC of 12,400/µL. On postoperative Day 2, her temperature was 98.5º F, with a maximum temperature of 101º F over the past 24 hours. Her blood pressure was 144/82, with a pulse of 102 bpm. The intraperitoneal drain had 40 cc of serous drainage over 24 hours.

The patient complained of increasing pain, nausea, and epigastric pain. Examination revealed a distended abdomen, with no bowel sounds identified. An abdominal x-ray revealed an ileus. A nasogastric tube was placed, offering some relief. 

On the morning of postoperative Day 3, the patient complained of increasing pain, despite passing some flatus. Her vital signs were essentially unchanged, with a temperature of 98.2º F, BP = 145/80, pulse = 100 bpm, and respirations of 22 per minute. The peritoneal drain had 50 cc of serous drainage over 24 hours. The woman’s abdomen was soft but distended, with some sluggish bowel sounds.

Later in the morning on postoperative Day 3, the pathologist personally notified the gynecologist that the biopsy specimen was consistent with a ruptured colonic diverticulum with adjacent abscess and smooth muscle with associated colonic mucosa. A surgical consult was obtained, and an abdominal computed tomography (CT) scan revealed a partial small bowel obstruction, an amorphous 4 x 6-cm left-sided pelvic mass containing fluid and gas, with possible diverticular disease.

The patient underwent surgical exploration with findings of a large, inflammatory mass encompassing the entire left side of the pelvis. There was a 1-cm hole found in the lateral portion of the sigmoid colon, as well as a residual ovarian cyst, densely adherent to the surrounding structures. Neither the left ovary nor the ovarian cyst could be excised in total; thus, the ovarian cyst was aspirated and biopsied.

The surgeon performed a segmental sigmoid colectomy and created a colostomy. During a 2-month postoperative course, complications included a small bowel obstruction, with multiple surgeries. Ultimately, the colostomy was reversed months later.

The patient filed a suit against the gynecologist, alleging misdiagnosis and negligently performed surgery.

At trial, the plaintiff’s experts included a gynecologist, who opined that the preoperative work-up was incomplete and should have included a pelvic exam and a CT scan, which would have established the diagnosis of a diverticular abscess. The elevated WBC count should have alerted the gynecologist to a potential infectious process, warranting further work-up prior to surgery.

Further, this expert testified that the operating gynecologist breached the standard of care by failing to properly identify the anatomic structures before excising tissue. The failure to recognize the bowel perforation and inability to remove the ovarian cyst resulted in major postoperative complications and multiple surgical procedures.

The plaintiff’s surgical expert echoed this opinion, further stating that the ultrasound did not demonstrate how much colon or rectum was involved, nor the location of any potential anastomosis or colostomy, precluding an appropriate preoperative informed consent. In addition, emergent surgery was not required, with better management being the placement of a percutaneous drain and antibiotics.

A general surgeon should have been consulted to establish the correct diagnosis, prior to surgical intervention. As a result of the complications and multiple surgeries, the patient is at risk for additional adhesion formation, bowel obstruction, and need for future surgery. Neither plaintiff’s expert was critical of the postoperative care.

Defense experts, including a gynecologist and general surgeon, testified that both the ED physician and the treating gynecologist thought the mass was ovarian in origin, supported by the abdominal and pelvic ultrasound. Further, the radiologist did not recommend a CT scan to further clarify the sonographic findings. The patient had no history of diverticular disease or long-term bowel-related symptoms. 

Thus, a diverticular abscess was unlikely. Thus, surgical consultation was not required before proceeding with surgery, which was a reasonable option in management. For further support, a defense medical expert testified that diverticular disease is uncommon in young individuals, again making the diagnosis of a diverticular abscess very unlikely. The elevated WBC could be consistent with either torsion or partial rupture of the ovarian cyst.

The defense experts testified that the large mass encountered at surgery was consistent with the preoperative diagnosis of an ovarian cystic mass. The markedly distorted anatomy and inability to excise the ovarian mass completely rendered aspiration and biopsy an appropriate management option. Postoperative management was appropriate, with a surgical consultation obtained in a timely manner when the pathology findings were known.

It was further noted that, at surgical re-exploration, the operating surgeons were not able to remove the ovarian cyst or ovary, and therefore pursued aspiration and biopsy. Regarding the potential for future surgery due to abdominal adhesions, the defense experts testified that the patient had significant adhesions prior to the incident surgery, even requiring a prior exploratory laparotomy and extensive adhesiolysis. Thus, the patient was already at risk for future surgical procedures due to the adhesive disease

After an 8-hour deliberation, the jury return a defense verdict.

Ostensibly, this case appeared to be a certain victory for the plaintiff. The ultimate result, a defense verdict, underscores the importance of excellent legal representation and the critical nature of expert witness selection, not only for their credibility, but also for their ability to engage the jury.

The defendant was prepared to explain the thought process underlying the probable diagnosis, the decision for surgery, and the management decisions during the incident surgery. Further, the defendant clearly explained the sequence of findings in the postoperative period and the associated decision processes.

The plaintiff’s experts were somewhat dogmatic in their opinions, rejecting the value of ultrasound and even the probability of the preoperative diagnosis of an ovarian cyst. Further, they dismissed that there are multiple approaches to management, particularly when unexpected findings, such as extensive adhesions, are encountered.

Contrasting this were the defense experts who discussed the value of various diagnostic modalities and the reasoning behind selecting specific modalities, such as ultrasound, CT, and magnetic resonance imaging. They supported the preoperative diagnosis of a large ovarian cyst. They expressed the difficult decisions one makes when encountering unexpected findings, which often lead to alternative treatment options.

The plaintiff’s experts seemed somewhat aloof and tended to “speak above the jury,” rather than at a level understood by the jury. In contrast, the defense experts were engaging and explained complex medical terms and decisions in simple terms, almost teaching the jury.

As a result, the defense opinions had greater impact and influence on the jury. The defense counsel was credited for excellent preparation of all defense witnesses for trial testimony. The selection of an excellent attorney and expert witnesses definitely impact the ultimate outcome of a case.

The outcome in this case underscores the importance of excellent legal representation and scrupulous expert witness selection.
