Laparoscopic image of carbon dioxide embolism during laparoscopic hepatectomy: a case report

Abstract

Abstract Background Carbon dioxide embolism is a life-threatening complication of laparoscopic hepatectomy. Case presentation A 59-year-old man was admitted for laparoscopic hepatectomy. Approximately 5 h after commencing the operation, we observed a gradual decline in the SpO2 from 100 to 94%, reduction in the ETCO2 from 44 to 19 mmHg, reduction in the systolic blood pressure from 100 to 82 mmHg, and elevation of the heart rate from 82 to 120 beats/min. Intraoperatively, the image displayed on the laparoscopic monitor revealed a small tear in the vein. The inspired O2 fraction was raised to 1.0, intravenous phenylephrine (0.1 mg bolus) was administered, and the respiratory rate was increased. After the patient was stabilized, the injured vein was cut and sealed. After the embolic event, the entire operation was completed without complications. Conclusions Careful observation of the laparoscopic monitor is important, particularly during establishment of pneumoperitoneum in patients undergoing laparoscopic hepatectomy.
