摘　　要：目的:探讨气腹后麻醉机呼吸参数对行腹腔镜手术患者呼吸动力学的影响。方法:随机抽样全麻行腹腔镜手术的80患者,分为A组(潮气量8ml/kg,呼吸频率12次/min,PEEP 0cmH_(2)O)与B组(CO_(2)气腹10min后调整潮气量为6ml/kg,呼吸频率15次/min,PEEP为5cmH_(2)O)。对比两组患者呼吸动力学指标。结果:A组患者T1和T2时的Plat、Peak和PetCO_(2)水平显著高于T0时,B组中T2时较T1显著降低,且B组患者SPO_(2)<92%的发生率显著低于A组(P<0.05)。结论:CO_(2)气腹后降低潮气量,提高通气频率与PEEP可降低全麻患者呼吸波动。Objective:To explore the effect of adjusting the respiratory parameters of the anesthesia machine after pneumoperitoneum on the respiratory dynamics of patients undergoing laparoscopic surgery.Methods:80 patients undergoing laparoscopic surgery under general anesthesia were randomly selected and divided into group A(tidal volume 8 ml/kg,respiratory rate 12 times/min,PEEP 0 cmH_(2)O)and group B(adjusted tidal volume 6 ml/kg,respiratory rate 15 times/min,PEEP 5 cmH_(2)O after 10 minutes of CO_(2)pneumoperitoneum).Compare respiratory dynamics indicators between two groups of patients.Results:The Plat,Peak,and PetCO_(2)levels of patients in Group A at T1 and T2 were significantly higher than those at T0,while those in Group B at T2 were significantly lower than those at T1.The incidence of SPO_(2)<92%in Group B was significantly lower than that in Group A(P<0.05).Conclusion:Reducing tidal volume,increasing ventilation frequency,and PEEP after CO_(2)pneumoperitoneum can reduce respiratory fluctuations in general anesthesia patients.
