硬膜外小剂量芬太尼对剖宫产术中寒战的影响

Effect of epidural small doses fentanyl on shivering during cesarean section

目的研究硬膜外腔注射小剂量芬太尼对剖宫产术中寒战的影响。方法剖宫产产妇１２０例，随机等分为两组，均选用连续硬膜外麻醉，硬膜外除局麻药外，Ａ组实验组加注芬太尼１．8μｇ／ｋｇ，Ｂ组（对照组）加注与Ａ组芬太尼量等容积的生理盐水。记录阻滞平面，观察产妇生命体征变化、寒战发生情况及新生儿情况。结果寒战发生例数 Ａ组 ２８例与 Ｂ组４０例具有显著差异（Ｐ＜ ０．０５）；胎儿取出前寒战发生倒数Ａ组６例与Ｂ组２１例具有非常显著差异（Ｐ＜０．０１）；两组间胎儿取出后１ｍｉｎ及５ｍｉｎＡｐｇａｒ评分无明显差异。结论硬膜外小剂量芬太尼能降低剖宫产术中寒战的发生率，小剂量芬太尼注入硬膜外腔对母婴均安全。

Objective To determine the effects of epidural with small doses of fentanyl to shive during cesarean section. Methods 120 cases parturients undergoing cesarean section were randomly allocated into Group A (n =60) and Group B (n = 60), all were continuous epidural anesthesia. Group A was fentanyl 1.8μg /kg and Group B was N. S. The parturients BP. HR. shivering and fetal were recorded. Results There were significant difference between the two groups (P < 0 .05). 28 parturients in Group A were shivered compared with 40 in Group B, Before fetal birth developed shivering compared with 6 in Group A and 21 in Croup B (P < 0.01 ). Two Groups with fetal birth were 1 min and 5 min Apgar no significant difference. Conclusion Small doses fentanyl of epidural can reduce shivering during cesarean section, and safety with parturients and fetals.
