目的评价听觉诱发电位指数(AAI)监测幼儿吸入七氟醚麻醉深度的准确性.方法择期全麻手术患儿50例,年龄1～3岁,ASA分级Ⅰ或Ⅱ级,异丙酚-顺阿曲库铵-瑞芬太尼麻醉诱导气管插管后行机械通气,维持PETCO2 35～ 45 mm Hg.随后高氧流量6 L/min洗入七氟醚,15 min后氧流量降低为3 L/min,调节呼气末七氟醚浓度(CETSev)依次为2.5%、2.8%、3.0%、3.5%、3.7%、4.0%,每个CETSev维持稳态3 min.分别于麻醉诱导前、诱导后、吸入七氟醚前即刻和不同CET Sev稳态时监测AAI.结果 AAI与CETSev呈明显负相关(r=-0.872,P＜0.01).结论单纯吸入七氟醚1.0～ 1.6MAC时AAI可准确监测幼儿的麻醉深度.

Objective To evaluate the accuracy of auditory evoked potential index (AAI) in monitoring the depth of sevoflurane anesthesia in infants.Methods Fifty ASA Ⅰ or Ⅱ pediatric patients,aged 1-3 yr,scheduled for elective surgery under general anesthesia,were enrolled in this study.Anesthesia was induced with propofol,cisatracurium and remifentanil.The patients were tracheal intubated and mechanically ventilated.PET CO2 was maintained at 35-45 mm Hg.Anesthesia was maintained with inhalation of sevoflurane.Fresh gas flow was first set at 6 L/min for 15 min and then reduced to 3 L/min.The end-tidal sevoflurane concentration (CETSev) was maintained at 2.5%,2.8%,3.0%,3.5%,3.7% and 4.0%.Each CETSev was maintained for 3 min.AAI was continuously monitored before induction of anesthesia,after induction,immediately before sevoflurane inhalation,and at the 6 CET Sev.Results AAI was negatively correlated with CET Sev (r =-0.872,P ＜ 0.01).Conclusion AAI can accurately reflect the depth of sevoflurane anesthesia in infants.
