七氟醚复合丙泊酚在小儿气道异物取出术中的麻醉效果

Objective To observe the anesthetic effect of sevoflurane combined with propofol total general anaesthesia in children undergoing tracheal foreign body removal. Methods Sixty patients aged from 1 to 4 years admitted for tracheal foreign body removal were randomly divided into two groups : sevoflurane group (n = 30) and ketamine group (n = 30). In the sevoflurane group, anaesthesia was induced and maintained with inhalation of sevoflurane and propofol 1.5 mg/(kg · h)] was administered continuously for anesthesia maintenance by micro-pump during operation. The ketamine group were pre-medicated with ketamine 6 mg/kg i. m for sedation, then an-aesthesia was induced with midazolam 0.1 mg/kg and ketamine 1.5 mg/kg i. v and was maintained with intravenous bolus of ketamine. Systolic blood pressure(SBP), Diastolic blood pressure(DBP) ,heart rate(HR) and saturation of percutaneous oxygen(SPO2) were monitored in both groups before anaesthesia inducation (T0) , after anaesthesia inducation and before operation (T1), at the time point of bronchial endoscopy(T2) ,endoscope remoral (T3) ,con-sciousness recovery(T4). The operation condition was evaluated by surgeons, and the incidence of bronchial spasm, glossal drop, nausea and vomiting were recorded both during operation and after operation. Results The SBP and HR increased at the time point of bronchial endoscopy in two groups and decreased after anaesthesia inducation in aevoflurane group. The SPO2 increased in two group after anaesthesia inducation. Compared with ketamine group, the time of consciousness recovery was shorter markedly in sevoflurane group. The occurrence of postoperative glossal drop was higher in ketamine group. Conclusion Sevoflurane combined with propofol is safe and effective during general anaesthesia of children undergoing tracheal foreign body removal.
