摘　　要：目的:合理控制麻醉期间患者呼吸末二氧化碳分压(PetCO2).方法:选择30例ASAI～Ⅱ级腹部手术患者,采用静脉诱导插管,静吸复合加肌肉松弛维持麻醉,分别以6 mL·kg-1、8 nL·kg-1、10 mL·kg-1的潮气量控制通气,呼吸比1:1.5,呼吸频率12 min-1,呼末二氧化碳(EtCO2)稳定时记录其值.结果:潮气量为10 mL·kg-1时EtCO2均为过度通气;潮气量为6mL·Kg-1时EtCO2在正常下限附近,但仍在正常范围.潮气量为8 mL·kg1-时EtCO2在正常范围中值区域.结论:PetCO2控制在正常范围时的潮气量为6～8 mL·kg-1.Objective:Properly control PetCO2 during a anesthesia period.Methods:Thirty ASA Ⅰ～Ⅱ patiens undergoing abdominal surgery were randomly divided into three groups.All patients were recived intubation after induceted with intravenous anesthetics.Anesthesia was mentained with introvenal-inhalation anesthetic and muscle relaxant.Tidal volum of IPPV was instituted to 6 mL·kg-1,8 mL·kg-1,10 mL·kg-1 respectively.I:E ratial to 1∶1.5,ventilation frequency to 12 min-1,and to record EtCO2 level.Results:In 10 mL·kg-1 vt group,EtCO2 showed over-ventilation,In 6 mL·kg-1 vt group,EtCO2 level was at upper limit of normal renge.Conclusion:In order to contral PetCO2 with in normal renge,tidal volum should be 6 to 8 mL·kg-1.
