One of the complications of laparoscopic surgery is carbon monoxide (CO) production under the use of electro-cautery. We studied 11 patients undergoing laparoscopic urological surgery. The concentrations of CO in peritoneal cavity and carboxyhemoglobin (HbCO) in arterial blood were measured before the operation under laparoscopy, during the use of electro-cautery and after the operation. The concentration of CO in peritoneal cavity reached 78 ppm during the use of electro-cautery but the HbCO level was unchanged. In the study on laparoscopic cholecystectomy (LC) performed previously, we had found no change of HbCO. The increase of CO on LC was more pronounced than in the present study. The concentration of CO in peritoneal cavity might be more dependent on the intensive use of electro-cautery than on operation time. Additionally the frequency of the insertion and extraction of the instruments through the trocar could have influenced it. CO could also be produced in the carbon dioxide cylinder. It should be investigated since it might contaminate the operating room.
腹腔镜手术的并发症之一是在使用电灼时会产生一氧化碳（CO）。我们研究了11例接受腹腔镜泌尿外科手术的患者。在腹腔镜手术前、使用电灼期间及手术后，测量了腹腔内CO浓度和动脉血中碳氧血红蛋白（HbCO）水平。使用电灼时腹腔内CO浓度达到78 ppm，但HbCO水平未发生变化。在之前进行的关于腹腔镜胆囊切除术（LC）的研究中，我们发现HbCO没有变化。LC时CO的增加比本研究更明显。腹腔内CO浓度可能更多地取决于电灼的频繁使用而非手术时间。此外，通过套管针插入和拔出器械的频率可能也会对其产生影响。CO也可能在二氧化碳气瓶中产生。由于其可能污染手术室，因此应该对此进行调查。
