【摘要】 目的：探究甲氧氯普胺和托烷司琼联合使用在预防全身麻醉结直肠癌手术老年患者术后恶心呕吐的效果及安全性。方法：选取德兴市第二人民医院于2021年2月—2024年1月行全身麻醉结直肠癌手术的101例老年患者作为前瞻性研究对象，按随机数字表法将其分为A组(n=50)和B组(n=51)；A组给予甲氧氯普胺进行治疗，B组则采用甲氧氯普胺联合托烷司琼进行治疗，对比两组患者的生命体征、疼痛程度、恶心呕吐发生率、术后恢复情况及术后72 h内不良反应发生率。结果：两组术毕时平均动脉压(MAP)、心率(HR)及血氧饱和度(SpO2)对比，差异均无统计学意义(Pgt;0.05)；B组术后6、12 h的视觉模拟评分法(VAS)评分均低于A组(Plt;0.05)；B组术后6、12、18 h的恶心、呕吐发生率均低于A组(Plt;0.05)。B组拔管时间、首次下床时间、首排气时间及住院时间均短于A组，且术后72 h内不良反应发生率低于A组(Plt;0.05)。结论：甲氧氯普胺联合托烷司琼能有效降低全身麻醉结直肠癌手术老年患者术后恶心呕吐的发生率，缩短恢复时间，减少术后72 h内不良反应发生。
