目的观察瑞芬太尼-七氟醚静吸复合全麻在小儿扁桃体手术的应用中对血流动力学的影响和苏醒情况。方法30例全麻下扁桃体切除术病人,男19例,女11例,ASA1级,以瑞芬太尼1ug/kg、丙泊酚1～2mg/kg、罗库溴铵0.4～0.6mg/kg麻醉诱导后气管插管,麻醉维持为瑞芬太尼4～8ml/h微量输注泵恒速输入,吸入1%～2%七氟醚,间断追加罗库溴铵0.15mg/kg。记录诱导前和术中血流动力学变化情况。结果注入瑞芬太尼和丙泊酚后血压、脉搏均下降。气管插管后明显回升。结论瑞芬太尼和七氟醚均起效快、作用时间短,无蓄积,适用于小儿扁桃体切除的短小手术。
Objective To observe the effects of remifentanil-sevoflurane combined with general anesthesia on hemodynamics and recovery during pediatric tonsil surgery. Methods Thirty patients with tonsillectomy underwent general anesthesia. There were 19 males and 11 females with ASA grade 1, with remifentanil 1ug / kg, propofol 1 ~ 2mg / kg, rocuronium 0.4 ~ 0.6mg / kg After anesthesia induction tracheal intubation, anesthesia was maintained at remifentanil 4 ~ 8ml / h constant infusion of trace infusion pump, inhalation of 1% to 2% sevoflurane, intermittent additional rocuronium 0.15mg / kg. Record pre-induction and intraoperative hemodynamic changes. Results After injection of remifentanil and propofol, blood pressure and pulse decreased. Tracheal intubation significantly rebounded. Conclusion Both remifentanil and sevoflurane have a rapid onset of action, short duration of action, and no accumulation, making them suitable for short surgeries in pediatric tonsillectomy.
