摘要 目的探讨舒芬太尼靶控输注(TCI)复合右美托咪定(DEX)镇静用于烧伤换药时的有效效应室浓度(EC)。方法80例烧伤换药患者采用DEX复合舒芬太尼TCI(Bovill模型)镇静镇痛,根据舒芬太尼EC不同分为A、B、C和D组,各20例。观察时点为揭开内层敷料和创面处理时第一观察时点4组初始设定浓度0.1、0.2、0.3和0.4ng/ml;第二观察时点浓度分别为0.2.0.3、0.4和0.5 ng/ml。通过序贯法来调整舒芬太尼浓度,计算舒芬太尼EC50和EC95,记录术中呼吸抑制情况,以及手术医生和患者满意度。结果揭开内层敷料时舒芬太尼EC50和EC95分别为0.210ng/ml和0.349 ng/ml,而创面处理时EC50和EC95分别为0.292 ng/ml和0.427ng/ml。4组患者和医生对换药过程均较满意,余3组患者和医师满意度显著高于A组(均P<0.05),C和D组分别有1和3例患者在换药中SpO2低于90%。结论DEX复合舒芬太尼TCI应用于烧伤换药是安全可行的揭开内层敷料时舒芬太尼EC50和EC95分别为0.210 ng/ml和0.349 ng/ml,创面处理时舒芬太尼EC50和EC95分别为0.292 ng/ml和0.427 ng/ml。
