不同剂量丙泊酚预防小儿术后躁动的效果和安全性分析

目的：探讨不同剂量丙泊酚对预防小儿术后躁动的影响。方法选择2012年9月至2013年6月在泸州医学院附属中医院择期行斜疝修补术的小儿60例，分为Ⅰ、Ⅱ、Ⅲ3组，3组患儿均采用七氟醚进行全身麻醉，术后分别采用0．10 mL／kg 的0．90％氯化钠注射液静脉注射、1．00 mg／kg 丙泊酚静脉注射1次和1．00 mg／kg 丙泊酚静脉注射2次，比较 3组患儿术后30 min 内躁动的发生率，并对患儿进行麻醉苏醒烦躁评分、Aldrete 改良评分和苏醒时间及出室时间比较。结果Ⅰ、Ⅱ、Ⅲ组患儿30 min 内躁动发生率分别为65．00％、25．00％及15．00％，3组患儿比较差异有统计学意义（P ＜0．05）；3组患儿在麻醉苏醒烦躁评分、Aldrete 改良评分和苏醒时间比较，差异有统计学意义（P ＜0．05），3组患儿出室时间比较，差异无统计学意义（P ＞0．05）。结论术后采用1．00 mg／kg 丙泊酚静脉注射2次，预防小儿术后躁动效果明显，安全性好，具有重要的临床参考价值。

Analysis on effect and safety of different doses of propofol for preventing pediatric postoperative agitation

Objective To explore the effects of the different doses of propofol for preventing postoperative agitation in chil-dren.Methods 60 children cases undergoing elective indirect inguinal hernia hernioplasty were selected in the Affiliated Hospital of Traditional Chinese Medicine,Luzhou Medical College from June 2011 to April 2011 and randomly divided into the group Ⅰ,Ⅱ andⅢ.The three groups were performed the general anesthesia with sevoflurane and postoperatively given 0.90% sodium chloride in-jection 0.10 mL/kg by intravenous injection,propofol 1.00 mg/kg by once intravenous injection and propofol 1.00 mg/kg by twice intravenous injection,respectively.The occurrence rate of postoperative agitation within 30 min was compared among 3 groups.The anesthesia recovery agitation score,improved Aldrete score,awakening time and time out of the operation room were also compared. Results The occurrence rates of agitation within postoperative 30 min in the group Ⅰ,Ⅱ and Ⅲ were 65.00%,65.00% and 15.00% respectively,the difference among three groups was statistically significant (P <0.05);the anesthesia recovery agitation score,improved Aldrete score and awakening time had statistically significant differences among 3 groups (P <0.05),the time out of the operation room had no statistical difference(P > 0.05).Conclusion Postoperative twice intravenous injection of propofol 1.00 mg/kg has obvious effect and good safety for preventing the postoperative agitation in children,which has important clinical reference value.
