目的 研究舒芬太尼腰硬联合阻滞麻醉在剖腹产中的应用及对血液动力学、术后牵拉痛与寒战发生率的影响。方 法 将276例拟行剖宫产产妇随机均分为观察组(罗哌卡因+舒芬太尼)和对照组(罗哌卡因)进行腰硬联合麻醉， 比较两组麻醉效果、血流动力学指标、术后寒战以及牵拉痛发生情况。结果 两组麻醉优良率分别为97.10% 和94.93%(P>0.05)；T2时刻两组HR和MAP与T0相比变化明显(P<0.05)，两组HR和MAP麻醉后T2和T3时刻差异显著 (P<0.05)；两组不良反应发生率分别为5.22%和8.40%(P>0.05)，术后寒战发生率分别为13.43%和28.24%(P<0.05)， 术后牵拉痛发生率分别为19.40%和41.22%(P<0.05)。结论 在剖腹产腰硬联合阻滞麻醉中小剂量应用舒芬太尼可以 提升麻醉质量，稳定血流动力学指标，减少产妇术后寒战和牵拉痛发生，从而保障手术顺利以及母婴安全。

Objective To study the application of sufentanil combined spinal-epidural anesthesia in caesarean section and its effects on hemodynamics and incidence rates of postoperative traction pain and chills. Methods 276 puerperae who underwent cesarean section were randomly divided into observation group (ropivacaine+ sufentanil) and control group (ropivacaine) for combined spinal-epidural anesthesia. The anesthetic effects, hemodynamic indexes and occurrence of postoperative chills and traction pain were compared between the two groups. Results The excellent and good rates of anesthesia in the two groups were 97.10% and 94.93% respectively (P>0.05). At T2, the HR and MAP in the two groups were significantly changed compared with those at T0 (P<0.05). There were significant differences in the HR and MAP at T2 and T3 after anesthesia between the two groups (P<0.05). The incidence rates of adverse reactions in the two groups were 5.22% and 8.40% respectively (P>0.05), and the incidence rates of postoperative chills were 13.43% and 28.24% respectively (P<0.05), and the incidence rates of postoperative traction pain were 19.40% and 41.22% respectively (P<0.05). Conclusion Low-dose sufentanil in combined spinal-epidural anesthesia for caesarean section can improve the anesthesia quality, stabilize hemodynamic indexes, and reduce the occurrence of postoperative chills and traction pain, thus ensuring smooth operation and maternal-infant safety.
