摘要
目的探究肺复张策略对肥胖患者腹腔镜手术肺功能的影响。方法将100例腹腔镜手术的肥胖患者随机分为两组,每组50例。观察组采用压力控制联合呼气末正压的通气模式,逐步增加和降低压力实施肺复张;对照组行常规容量控制通气。比较两组患者血流动力学指标和呼吸指标。结果两组患者的血流动力学指标均平稳;在气腹30 min、气腹60 min、气腹90 min、放气时的肺顺应性、OI指数上,观察组显著比对照组高(P<0.05),而在D(a-e)CO2水平上,观察组显著比对照组低(P<0.05)。结论将肺复张策略应用于行腹腔镜手术的肥胖患者后,可改善患者肺顺应性,提高氧合指数,不会对循环系统造成不良影响,此方法可广泛应用于临床。
Objective To study the influence of lung recruitment maneuvers(LRM)in obese patients undergoing laparoscopic surgery.Methods 100 obese patients undergoing laparoscopic surgery were randomly assigned to two groups,50 cases in each group.The control group took pressure control plus endexpiratory positive pressure in a progressive manner;the control group took conventional volume control.Hemodynamic and respiratory indicators were probed.Results Hemodynamic indicators for two groups were stable;upon 30 min,60 min and 90 min of pneumoperitoneum and deflation,lung compliance and OI in observation group was higher(P<0.05);observation group had lower values of D(a-e)CO2(P<0.05).Conclusion LRM can improve the lung compliance and OI,and produce less impact in circulatory system.
