Abstract
Laparoscopy is widely used because it induces minimal postoperative pain and facilitates rapid recovery. However, carbon dioxide (CO2) embolism is a rare but potentially fatal complication of laparoscopic surgery. Earlier reports have shown that decreased end-tidal CO2 (ETCO2) and increased partial pressure of CO2 might be useful indicators of CO2 embolism. We herein report a case of CO2 embolism after the freed bladder neck was released during laparoscopic radical prostatectomy. Sudden hemodynamic disorder and increased ETCO2 combined with immediate arterial blood gas analysis led us to suspect CO2 embolism, which was confirmed by the aspiration of foamy blood from the central venous catheter. The patient was successfully resuscitated and recovered well. This case illustrates that hemodynamic collapse accompanied by increased ETCO2 can indicate CO2 embolism.
