探讨小剂量异丙酚、芬太尼及两路供氧在小儿气管异物取出术麻醉应用中的可行性及优点。选择小儿气管异物取出术２１ 例。对照组１１ 例，采用氯胺酮，羟丁酸钠麻醉，行ＨＦＪＶ；实验组１０ 例，行小剂量异丙酚２ｍｇ／ｋｇ、芬太尼３μｇ／ｋｇ，静注，经口置细硅塑管于声门下行ＨＦＪＶ，另一路氧经支气管镜的侧孔持续供氧。观察两组麻醉的平稳度及可控性。结果，两组麻醉的平稳６～１０ 分钟内无明显差异，但手术时间较长，循环参数及ＳＰａＯ２ 数值的变化及术后苏醒两组间有显著性差异（ Ｐ＜０．０１）。提示，小剂量异丙酚、芬太尼两路供氧用于小儿支气管异物取出术的麻醉可控性强，苏醒快，分泌物少，并可延长手术操作时间。
To explore the feasibility and advantages of low-dose propofol, fentanyl and two-way oxygen supply in pediatric tracheal foreign body removal anesthesia. Select pediatric tracheal foreign body removal in 21 cases. In the control group, 11 cases were treated with ketamine and sodium oxybate, and were given HFJV. In the experimental group, 10 cases were treated with low dose propofol 2mg / kg, fentanyl 3μg / kg, Glottis downstream HFJV, the other way through the bronchial side hole continuous oxygen supply. The stability and controllability of anesthesia in both groups were observed. The results showed that there was no significant difference between the two groups in 6 to 10 minutes, but the operation time was longer, the change of circulatory parameters and SPaO2 values and postoperative recovery were significantly different (P <0.01). Prompt, low-dose propofol, fentanyl two oxygen for bronchial foreign body removal of anesthesia controllable, fast recovery, less secretions, and can extend the operation time.
