  • Obtained a defense verdict in a wrongful-death action in which a woman underwent an emergency Caesarean section during which she experienced significant blood loss when the surgeon transected her uterine vessels. After the bleeding was controlled, clients – the anesthesia team – managed the resuscitation, replacing the lost blood with transfusions, fluids and medications. Plaintiffs’ allegations included failure to insert an arterial line or a central venous pressure line and failure to administer appropriate volumes of blood products. Plaintiffs sought $25 million, primarily for future needs of woman’s children. Defendants contended death was due to an amniotic fluid embolism. After two-week trial, jury found in favor of client.

The defense argued that the procedure was necessary and was performed properly and that the plaintiff's current problems were caused by her pre-existing medical conditions.
  • Received a defense verdict in which the plaintiff underwent elective surgery. During the surgery, the plaintiff suffered a perforated esophagus, most likely the result of the intubation efforts by our client, the anesthesiology team for the surgery. Although perforation is a known complication, it is extremely rare. The trial went forward against our clients and another doctor, and the jury returned a complete defense verdict. The plaintiff initially appealed the judgment, but then dismissed the appeal.
  • Defended two gastric-bypass surgeons in a suit brought by one of their former patients who developed a neurological condition caused by a vitamin deficiency following her obesity surgery.

The jury returned a defense verdict, which was confirmed on appeal.

Medical Malpractice – Skilled-Nursing Facilities

  • Secured a significant verdict when the plaintiff, the daughter of a former nursing home resident, sued on behalf of the resident who died during a heat wave in St. Louis at a time when the air conditioning system was not activated. Four other residents died at the nursing home during a 48-hour period. The medical examiner concluded that four of the residents died of hyperthermia. The plaintiff’s counsel argued that the resident died as a result of exposure to hot temperature, a fall from her wheelchair, and lack of adequate nutrition and hydration. The plaintiff sued the nursing home, its owner, the owner’s and nursing home’s management companies, and four employees. Directed verdicts were obtained on behalf of the owner, the nursing home management company and the four employees. Plaintiff sought $50 million in damages. After a five week trial, the jury returned a verdict in favor of plaintiff for $275,000, against the nursing home and owner’s management company defendants only.
  • Obtained a complete defense verdict for a skilled-nursing facility in a wrongful-death action. While being transferred from her bed to a wheelchair, the female plaintiff suffered a left knee injury. Two weeks later, she complained of pain in her left lower leg and was sent to the hospital. While at the hospital, she was initially diagnosed with a deep vein thrombosis. She was then diagnosed with a fractured femur in her left leg. Because of the severity of the fracture and her underlying medical conditions, the woman’s left lower leg was amputated. The resident returned to the skilled-nursing facility. Two weeks later she suffered a stroke and subsequently died. After a two-week trial, the jury found the facility was not responsible in the woman's death.
  • Obtained a successful jury verdict for a skilled nursing facility in a wrongful death suit. An 88-year-old resident had fallen while unattended in her room. She suffered a fractured leg, wounds, and infection, and passed away three months later. The plaintiff--the resident's daughter--alleged that the injuries and death were due to inadequate staffing, lack of oversight and poor care, and sued for $1.8 million. After a week-long trial, the jury returned a complete defense verdict in the facility's favor.

Pro Bono

  • Reunited a mother with her 3-year-old son, who had been wrongfully withheld from her for more than a year. The client was a Canadian woman who lived in northern Saskatchewan on a reserve, similar to a Native American reservation in the United States. She had allowed her son’s paternal grandparents to take the boy to the grandparents’ home in the United States for a visit. However, the grandparents soon refused to return the boy and then cut off all contact. Thereafter, the grandparents filed state court proceedings to be appointed the boy’s legal guardian, claiming that the mother had “abandoned” the boy and that the whereabouts of the mother were unknown. The mother’s attempts to obtain assistance through local Canadian attorneys were unsuccessful. The grandparents then ignored a request from the Canadian government that the boy be returned. The client was referred through the U.S. State Department. A petition for return of the child was filed under the International Child Abduction provision of The Hague Convention. After expedited discovery and a two-day trial in U.S. District Court, Eastern District of Missouri, the court granted the mother’s petition and ordered that the grandparents return the boy. Mother and son were reunited a few days later.
