BACKGROUND: Intraoperative hypothermia is a common complication after neuraxial block in cesarean delivery. At least 1 animal study has found that carbohydrate loading can maintain the body temperature of rats during general anesthesia, but it is unclear whether carbohydrate loading is beneficial for body temperature maintenance in parturient women during combined spinal-epidural anesthesia (CSEA) for elective cesarean delivery. METHODS: Women undergoing elective cesarean delivery were randomized into a control group (group C), an oral carbohydrate group (group OC), or an oral placebo group (group OP), with 40 women in each group. Core body temperature (Tc) and body surface temperature (Ts) before and after cesarean delivery, changes in Tc (ΔTc) and Ts (ΔTs), and the incidence of side effects (eg, intraoperative shivering) were compared among the groups. RESULTS: The postoperative Tc (core body temperature after cesarean delivery [Tc2]) of group OC (36.48 [0.48]°C) was higher than those of group C (35.95 [0.55]°C; P < .001), and group OP (36.03 [0.49]°C; P = .001). The ΔTc (0.30 [0.39]°C) in group OC was significantly smaller than those in group C (0.73 [0.40]°C; P = .001) and group OP (0.63 [0.46]°C; P = .0048). CONCLUSIONS: Oral carbohydrate loading 2 hours before surgery facilitated body temperature maintenance during CSEA for elective cesarean delivery.

选择性剖宫产腰硬联合麻醉术前口服碳水化合物负荷对体温的影响

背景：术中低温是剖宫产中椎管内阻滞后常见的并发症。至少有 1 项动物研究发现，碳水化合物负荷可在全身麻醉期间维持大鼠的体温，但尚不清楚碳水化合物负荷是否有利于产妇在选择性剖宫产期间腰硬联合麻醉（CSEA）期间的体温维持. 方法：接受选择性剖宫产的妇女随机分为对照组（C 组）、口服碳水化合物组（OC 组）或口服安慰剂组（OP 组），每组 40 名妇女。剖宫产前后的核心体温 (Tc) 和体表温度 (Ts)，Tc (ΔTc) 和 Ts (ΔTs) 的变化，以及副作用的发生率（例如，术中颤抖）进行比较。结果：OC组术后Tc（剖宫产后核心体温[Tc2]）（36.48 [0.48]°C）高于C组（35.95 [0.55]°C；P < .001），组OP (36.03 [0.49]°C；P = .001)。OC 组的 ΔTc (0.30 [0.39]°C) 显着小于 C 组 (0.73 [0.40]°C; P = .001) 和 OP 组 (0.63 [0.46]°C; P = .0048) . 结论：手术前 2 小时口服碳水化合物负荷促进 CSEA 期间选择性剖宫产期间的体温维持。OC 组的 39]°C）显着小于 C 组（0.73 [0.40]°C；P = .001）和 OP 组（0.63 [0.46]°C；P = .0048）。结论：手术前 2 小时口服碳水化合物负荷促进 CSEA 期间选择性剖宫产期间的体温维持。OC 组的 39]°C）显着小于 C 组（0.73 [0.40]°C；P = .001）和 OP 组（0.63 [0.46]°C；P = .0048）。结论：手术前 2 小时口服碳水化合物负荷促进 CSEA 期间选择性剖宫产期间的体温维持。
