摘要 目的探讨靶控输注舒芬太尼复合丙泊酚在中老年患者全静脉麻醉苏醒过程中,患者恢复满意自主呼吸时的舒芬太尼效应室血浆药物浓度。方法选择中老年全静脉麻醉患者57例,随机分为三组各19例,按A组0.2ng/ml、B组0.4ng/ml、C组0.6ng/ml输注舒芬太尼,复合丙泊酚3μg/ml,进行全身麻醉诱导及术中维持,术毕前1小时停止输注舒芬太尼,术毕时停止输注丙泊酚,待患者自然苏醒。记录患者出现自主呼吸、恢复满意自主呼吸、清醒、拔除气管插管等时刻的时间、药物效应室血浆浓度及药物总量。结果三组患者自主呼吸出现、恢复满意呼吸时的丙泊酚血药浓度A组与B、C组比较差异有显著性,B组与C组比较差异无显著性。停止输注舒芬太尼后,三组患者分别经过了(36.89±20.05)分钟、(57.53±14.26)分钟、(83.42±23.38)分钟出现自主呼吸,此时舒芬太尼血药浓度分别为(0.1±0.03)ng/ml、(0.14±0.03)ng/ml、(0.17±0.04)ng/ml;经过了(44.84±20.08)分钟、(67.58±17.91)分钟、(92.63±25.85)分钟恢复满意自主呼吸,此时血药浓度分别为(0.09±0.02)ng/ml、(0.13±0.02)ng/ml、(0.16±0.04)ng/ml,降至(0.08±0.02)ng/ml、(0.12±0.02)ng/ml、(0.15±0.04)ng/ml时,三组患者达到拔除气管插管标准。结论不同靶浓度舒芬太尼复合丙泊酚持续输注后,呼吸恢复时的舒芬太尼血药浓度不是一个确定值,而是低浓度输注者的呼吸恢复时舒芬太尼血药浓度比高浓度者低。
