摘要 目的:探讨麻醉废气过滤器对七氟醚吸入全身麻醉苏醒的加速作用。方法:择期全麻患者20例,按麻醉时间先后顺序将同一患者分为前后两组。对照组(C组):在全麻诱导后持续吸入1.8%七氟醚50 min,停止吸入七氟醚,记录1 min(T1)、3 min(T2)、5 min(T3)、10 min(T4)、15 min(T5)时的呼气末七氟醚浓度。过滤组(F组):同一患者继续吸入1.8%七氟醚50 min,停止吸入七氟醚,在麻醉机吸气端与螺纹管之间接入麻醉废气过滤器,记录1 min(T1)、3 min(T2)、5 min(T3)、10 min(T4)、15 min(T5)时的呼气末七氟醚浓度。结果:两组停吸七氟醚后,同时间点比较,呼气末七氟醚浓度F组低于C组,两组比较差异均有统计学意义(P<0.05或P<0.01)。结论:在麻醉机吸气端与螺纹管之间置入麻醉废气过滤器后,患者体内七氟醚能够更快速地排出至体外,患者苏醒时间将明显缩短,全麻苏醒后安全性得到提升。
