目的 探讨丙泊酚、氯胺酮、瑞芬太尼静脉复合麻醉对于小儿隐睾固定术的麻醉效果。方法 选取80例需行小儿隐睾固定术的患儿，随机分为两组，对照组（39例）给予丙泊酚、氯胺酮静脉注射麻醉，观察组（41例）给予丙泊酚、氯胺酮、瑞芬太尼静脉麻醉。观察并记录两组心率（HR）、平均动脉压（MAP）、血氧饱和度（SpO₂）、苏醒时间、丙泊酚和氯胺酮给药剂量及术后不良反应事件，评价丙泊酚静脉复合麻醉对于小儿隐睾固定术的麻醉效果。结果 注药前、注药5 min、切皮时两组MAP、HR、SpO₂相比，差异无统计学意义。牵引睾丸时，观察组MAP、HR明显低于对照组（P<0.05）；两组SpO₂相比，差异无统计学意义；与对照组相比，观察组患儿苏醒时间较短（P<0.05），且丙泊酚及氯胺酮用量均明显少于对照组（P<0.05）；术后不良反应情况相比，差异无统计学意义。结论 丙泊酚、氯胺酮、瑞芬太尼静脉复合麻醉对小儿隐睾固定术具有较好的麻醉效果，麻醉过程平稳，对患儿生命体征影响较小，术后苏醒较快且不增加不良反应，值得临床推广使用。

Objective To discuss the anesthetic effect of iv injection with propofol for pediatric orchiopexy. Methods Totally 80 children who needed orchiopexy were selected, and were divided into two groups randomly. The control group (39 cases) were iv given propofol and ketamine for anesthesia. The observation group (41 cases) were iv given propofol, ketamine, and remifentanil. The anesthetic effect of propofol for pediatric orchiopexy was evaluated by HR, MAP, SpO₂, recovery time, dosage of propofol and ketamine, and postoperative adverse reaction. Results Before the injection and injection for 5 min, there was no statistical significance on MAP, HR, and SpO₂ between two groups. Pulling the testicles, the MAP and HR in observation group were lower than those in control group (P<0.05). There was no statistical significance on SpO₂. The recovery time of observation group was shorter than that of control group (P<0.05). And the dosages of propofol and ketamine in observation group were also less than those in control group (P<0.05). There was no statistical significance on postoperative adverse reaction between two groups. Conclusion The iv anesthesia with propofol has a good anesthetic effect on the pediatric orchiopexy. The anesthesia is stable and has little effect on vital signs, rapid postoperative recovery without increasing adverse reaction, which is worthy of clinical use.
