腔镜手术气腹压对呼气末二氧化碳的影响

Effect of Pneumoperitoneum Pressure on End Expiratory Carbon Dioxide in Endoscopic Surgery

目的:探讨腔镜手术气腹压对呼气末二氧化碳的影响。方法:选取2018年1月~2020年12月收治的200例腹腔镜手术患者,随机分为对照组与观察组,每组100例。观察组患者在腔镜手术中维持12mmHg气腹压,对照组患者则维持15mmHg气腹压。对比两组患者手术情况,并使用旁流法测定患者呼气末二氧化碳分压,进行对比分析。结果:观察组患者MAP和SpO_(2)水平高于对照组患者,HR水平低于对照组患者(P<0.05),观察组患者睁眼时间、自主呼吸恢复时间、拔管时间和定向力恢复时间均短于对照组患者(P<0.05)。观察组患者术中呼气末二氧化碳分压水平低于对照组患者(P<0.05)。结论:适当降低腔镜手术中气腹压助于降低患者呼气末二氧化碳分压,从而使患者血流动力学相关参数更加平稳,苏醒更快,具有积极影响。

Objective:To investigate the effect of pneumoperitoneum pressure on end expiratory carbon dioxide in endoscopic surgery.Methods:200 patients with laparoscopic surgery from January 2018 to December 2020 were selected and randomly divided into observation group and control group,with 100 cases in each group.The observation group maintained 12mmHg pneumoperitoneum pressure during endoscopic surgery,while the control group maintained 15mmHg,surgery index of the two groups were compared,and the end expiratory partial pressure of carbon dioxide was measured by side flow method.Results:The MAP and SpO_(2) levels of the observation group were higher than those of the control group,and the HR level was lower than that of the control group(P<0.05).The eye opening time,spontaneous breathing recovery time,extubation time and orientation recovery time of the observation group were shorter than those of the control group(P<0.05).The level of end expiratory carbon dioxide partial pressure in the observation group was lower than that in the control group(P<0.05).Conclusion:Appropriate increase of pneumoperitoneum pressure during endoscopic surgery can help to reduce the end expiratory partial pressure of carbon dioxide,so as to make the hemodynamic parameters more stable and wake up faster,which has a positive impact.
