BACKGROUND Postoperative nausea and vomiting are common complications after gynecologic laparoscopic surgery. Pyridoxine has been recommended as a first-line drug to prevent and treat nausea and vomiting during pregnancy; however, its efficacy in preventing postoperative nausea and vomiting remains unclear. METHODS Patients of 18 to 65 yr old who received elective gynecologic laparoscopic surgery under general anesthesia were randomized into either the pyridoxine group or the control group. The pyridoxine group received 0.2 g of vitamin B 6 before anesthesia induction, and the control group received normal saline intravenously. Both groups received a similar regimen of combined intravenous and inhalation general anesthesia. All patients received dexamethasone (intravenous) after anesthesia induction and ondansetron (intravenous) before surgery completion. Postoperative nausea and vomiting occurrence was recorded according to the patients' self-reported data. Other clinical data were collected from hospital system, and concentrations of blood interleukin-6 and substance P were measured by enzyme-linked immunosorbent assay. RESULTS A total of 442 patients were screened, and 240 patients were equally randomized to the pyridoxine or control group. The incidence of postoperative nausea and vomiting was statistically significant lower in the pyridoxine group than in the control group (16.7% [20 of 120] vs . 35.8% [43 of 120]; relative risk = 0.47 [95% CI, 0.29 to 0.74]; absolute risk reduction = 0.20 [95% CI, 0.08 to 0.30]; P = 0.001), and pyridoxine decreased the incidence of postoperative nausea (12.5% [15 of 120] vs . 35% [42 of 120]; relative risk = 0.36 [95% CI, 0.21 to 0.61]; absolute risk reduction = 0.23 [95% CI, 0.12 to 0.33]; P < 0.001). There were no statistical differences in postoperative vomiting, time to the first postoperative nausea and vomiting occurrence, pain, serum interleukin-6 and substance P, and leukocyte and neutrophil counts. CONCLUSIONS In this single-center randomized trial, pyridoxine plus dexamethasone and ondansetron reduced the incidence of postoperative nausea and vomiting in patients undergoing elective gynecologic laparoscopic surgery under general anesthesia. These findings need to be validated in multicenter studies in diverse populations to ensure generalizability.

吡哆醇预防妇科腹腔镜手术术后恶心和呕吐:一项双盲随机对照试验。



背景 术后恶心和呕吐是妇科腹腔镜手术后的常见并发症。吡哆醇已被推荐作为预防和治疗妊娠期恶心和呕吐的一线药物;然而,其预防术后恶心和呕吐的疗效仍不清楚。方法 将 18 至 65 岁在全身麻醉下接受择期妇科腹腔镜手术的患者随机分为吡哆醇组或对照组。吡哆醇组麻醉诱导前给予维生素 B 6 0.2 g,对照组静脉给予生理盐水。两组接受相似的静脉和吸入联合全身麻醉方案。所有患者在麻醉诱导后接受地塞米松 (静脉注射),并在手术完成前接受昂丹司琼 (静脉注射)。根据患者自我报告的数据记录术后恶心和呕吐的发生情况。从医院系统收集其他临床资料,通过酶联免疫吸附测定法测定血白细胞介素 6 和 P 物质的浓度。结果 共筛选出 442 例患者,其中 240 例患者平均随机分为吡哆醇组或对照组。吡哆醇组术后恶心和呕吐的发生率比对照组低,具有统计学意义(16.7% [120 例中的 20 例] 对 35.8% [120 例中的 43 例];相对风险 = 0.47 [95% CI,0.29 至 0.74];绝对风险降低 = 0.20 [95% CI,0.08 至 0.30];P = 0.001),吡哆醇降低了术后恶心的发生率 (12.5% [15/120] vs .35% [42/120];相对风险 = 0.36 [95% CI,0.21 至 0.61];绝对风险降低 = 0.23 [95% CI,0.12 至 0.33];P < 0.001)。 术后呕吐、术后首次恶心和呕吐发生时间、疼痛、血清白细胞介素 6 和 P 物质以及白细胞和中性粒细胞计数无统计学差异。结论 在这项单中心随机试验中,吡哆醇联合地塞米松和昂丹司琼降低了全身麻醉下择期妇科腹腔镜手术患者术后恶心和呕吐的发生率。这些发现需要在不同人群的多中心研究中得到验证,以确保可推广性。
