Cardiac Arrest due to Carbon Dioxide Embolism During Laparoscopic Gynecologic Surgery of a Patient with Previous Abdominal Surgery: A Case Report

ABSTRACT

Catastrophic carbon dioxide (CO2) embolism is a rare, but potentially life-threatening, the complication of laparoscopic gynecologic surgery. We report the case of a healthy 53-year-old woman who developed CO2 embolism and cardiac arrest during laparoscopic surgery. She had a history of two cesarean sections and had extensive peritoneal adhesions. After placement of the trocar and insufflation of CO2, end-tidal CO2 dropped from 35 to 15 mm Hg, and the patient had a cardiovascular collapse. In this patient, CO2 embolism was diagnosed on the basis of a sudden decrease in end-tidal CO2, hypotension, and hypoxemia. The patient was managed quickly and aggressively. The patient recovered completely following the treatment for CO2 embolism, with no cardiopulmonary or neurological sequelae. There is an increased risk of catastrophic CO2 embolism during laparoscopic gynecologic surgery in patients with previous abdominal surgery. Therefore, the surgeon and anesthesiologist should remain vigilant to promote early detection of CO2 embolism.
