No-Cause Jury Verdict Secured in Wrongful Death Trial

We successfully obtained a no-cause jury verdict in a 13-day wrongful death trial. The decedent, a 59-year-old man, was admitted to the emergency room on February 15, 2019, with complaints of abdominal pain, decreased appetite, and constipation, despite the use of laxatives. The patient did not complain of any nausea, vomiting, or diarrhea. He had a significant medical history including diabetes, hypertension, prior coronary artery stenting, morbid obesity (with past gastric bypass surgery), longstanding ventral hernia, and back pain. A CT scan revealed multiple hernias and a potential closed-loop bowel obstruction, leading to a surgery consultation. Our client, an emergency general surgeon, interpreted that the patient did not have a closed loop or any significant obstruction and recommended non-surgical management. The patient was approved to have clear liquids, and had a vomiting incident shortly after, but our client was not notified. The patient was returned to NPO status, and after improving overnight, he was returned to “clears” and additional medical and renal consults were ordered. Our client did not receive any communications from the residents/nurses of any changes in the patient’s condition. On February 18, 2019, two rapid responses were called due to increased heart rate and vomiting. It is believed that the vomiting resulted in aspiration, causing sepsis, ultimately leading to the patient’s death. During the trial, the plaintiff’s sole medical expert highlighted imaging on the wrong hernia, which called into question all of his opinions in the case. We made key objections related to the expert testimony, limiting what the allegations were, and preventing new allegations from being made. After approximately two and a half hours of deliberating, the jury returned a no-cause verdict.

Won Unanimous Defense Verdict in High-Exposure Birth Injury Case

We secured a unanimous defense verdict in a high-exposure birth injury case, successfully proving that our client’s obstetric care met accepted standards despite claims of negligence and lasting injury.The plaintiff, the mother, alleged the obstetrician defendant was negligent in failing to identify her baby as large for gestational age in the prenatal period, in failing to proceed with a cesarean section during the labor, and in negligently performing a forceps delivery. The plaintiff alleged, as a result of her injuries from the delivery, she suffered pelvic organ prolapse, incontinence, and ongoing pain and suffering. The plaintiff underwent two subsequent gynecologic surgeries and alleged, as result of her ongoing pain, she would never be able to return to work for the remainder of her life. Through the testimony of our client and experts, we were able to establish the care provided by the obstetrician was within accepted standards of care and the decision to proceed with the delivery as performed was the safest option for the mother and baby. The jury returned a unanimous verdict in favor of our client.
