摘要
目的：探讨经腹腔与经腹膜后入路手术CO2气腹对患者血气的影响。方法：选择美国麻醉师协会（ASA）分级I．Ⅱ级行后腹腔镜手术的泌尿外科病例和腹腔镜手术的普外科及妇科病例各50例，监测气腹前（TO）、气腹后30min（T1）、60min（T2）及气腹结束后30min（T3）动脉血气的变化。结果：两组患者组内气腹后30min、60min的pH较气腹前降低，PaC02较气腹前升高（P〈0．05）；组间后腹腔组气腹后30min、60min的pH降低和PaCO2升高较腹腔组更明显（P〈0．05）。结论：后腹腔人路手术CO2气腹对患者血气的影响更大，术中需加强呼吸管理和血气的监测。
Objective： To explore the effects of Co2 insufflation on arterial blood gas in laparoscopic surgery and retroperitoneal laparoscopic surgery under general anesthesia. Methods： One hundred patients with American Society of Anesthesiologists （ASA）grade I - II. Fifty patients underwent elective retroperitoneoscopic urologic surgery and others underwent laparoscopic general or gynecological surgery.Arterial blood gas were measured at four time points：time before CO2 insufflation,30 and 60 minutes after insufflation,30 minnutes after exsufflation. Results： In the two groups and between the two groups,pH was decreased and PaCO2 increased significantly （P〈0.05）at 30 and 60 minutes after insufflation. Conclusion： Retroperitoneal CO2 insufflation produces more effects on the patients＇s arterial blood gas.Special attention should be paid to respiration administration and arterial blood gas monitoring.
