摘要
目的 比较全麻诱导期三代喉罩（proseal laryngeal mask airway,PLMA）置入和气管内插管对患者心血管反应和BIS的影响.方法 选择择期行腹腔镜胆囊切除术（LC）全麻手术的患者60例,ASA Ⅰ或Ⅱ级,随机均分为气管插管组（A组）和PLMA组（B组）.比较两组患者诱导前（T1）、诱导后（T2）、PLMA置人或气管插管后即刻（T3）、1 min（T4）、3 min（T5）时SBP、HR、BIS值的变化.结果 B组PLMA置入前后SBP、HR、BIS值组内差异无统计学意义;A组T3～Ts时SBP明显高于、HR明显快于T2时（P＜0.05）,T3、T4时BIS值明显高于T2时和B组（P＜0.05）.结论 在相同麻醉深度下,全麻诱导期使用PLMA能保持患者循环系统稳定,且不使中枢神经兴奋性增高;用血流动力学的变化预测麻醉深度的变化并不具有特异性.
Objective To compare the effect of PLMA insertion or tracheal intubation on hemodynamics and bispectral index（BIS） during general anesthesia induction.Methods Sixty patients,ASA Ⅰ or Ⅱ,undergoing Laparoscopic cholecystectomy（LC） were randomly divided into two groups with 30 each：PLMA insertion group （group B） and tracheal intubation group （group A）.SBP,HR and BIS were compared before and after induction （T1 and T2）,immediately after （T3）,1 min （T4） and 3 min （T5） after PLMA insertion or tracheal intubation.Results There was no significant difference in SPP,HR and BIS within group B.SBP and HR from T3 to Ts were significantly higher than T2 in group A （P〈0.05）.BIS at T3 and T4 in group A were higher than those at T2 and group B（P〈0.05）.Conclusion Hemodynamics will be stable during PLMA placement at the same anesthesia depth without exciting central nervous system.Hemodynamics is not a specific anesthesia depth predictor.
