本研究比较异丙酚、芬太尼与羟丁酸钠γ-OH)三种麻醉方法用于小儿气管异物取出术,以探讨其麻醉效果及安全性。资料与方法 50例气管异物小儿随机分为三组,术前均肌注阿托品0.02mg·kg~(-1)。γ-OH组:(R组,n=20)用75mg·kg~(-1)γ-OH缓慢静注,麻醉深度不足时分次静注氯胺酮1mg·kg~(-1)至麻醉满意。异丙酚组:(P组,n=15)以3mg·kg~(-1)异丙酚稀释后缓慢静注,3分钟后每5分钟静注1mg·kg~(-1)维持麻醉;芬太尼组:(F组,n=15)用2μg·kg~(-1)芬太尼1分钟后缓慢静注异丙酚2mg·kg~(-1),两组麻醉深度不足时分次追加1mg·kg~(-1)异丙酚至满意。三组均待意识消失后加用表面麻醉。注药前后均面罩吸纯氧,置入支气管镜后通过侧孔吸氧,SpO_2<95%时经侧孔行T管辅助呼吸。
This study compared propofol, fentanyl and sodium oxybate γ-OH) three anesthesia for pediatric tracheal foreign body removal to explore the anesthetic effect and safety. Materials and Methods 50 cases of children with tracheal foreign body were randomly divided into three groups, preoperative intramuscular injection of atropine 0.02mg · kg ~ (-1). γ-OH group: (R group, n = 20) was slowly intravenously injected with 75 mg · kg -1 γ-OH. When the anesthetic depth was insufficient, ketamine (1 mg · kg -1) Propofol group: (P group, n = 15) were treated with 3 mg · kg -1 propofol and then slowly intravenously. After 3 minutes, 1 mg · kg -1 was intravenously administered every 5 minutes to maintain anesthesia. Fentanyl group: (F group, n = 15) Propofol 2 mg · kg ~ (-1) was injected intravenously 1 min after 2 μg · kg ~ (-1) fentanyl. Append 1mg · kg -1 propofol to satisfactory. Three groups were to disappear after the addition of surface anesthesia. Before and after injection, the mask inhaled pure oxygen, placed in the bronchoscope and then through the side hole oxygen, SpO_2 <95% through the side hole T tube assisted breathing.
