Carbon Dioxide Embolism Resulting From Liver Laceration During Peritoneal Optical Trocar Entry

Abstract

Venous air emboli have been reported to occur in numerous settings, including trauma, various surgical procedures, both laparoscopic and radiologically, and even idiopathically. In this case study, a liver laceration was made during a robot-assisted left colectomy and colostomy in a 69-year-old female resulting in air embolism during insufflation. A drop in end-tidal CO2 was noted and the patient went into immediate cardiac arrest. Adequate pressure was applied and over-suturing of the liver laceration was made with reverse Trendelenburg positioning during the administration of cardiopulmonary resuscitation (CPR) for approximately one minute. The patient completed an open hemicolectomy the following day and made a complete recovery. Preventative and intraoperative measures to prevent further recurrences of venous air emboli are discussed.
