Objective To observe the efficacy and side effect of olanzapine combined with tropisetron, dexamethasone for the pre-vention of highly emetogenic chemotherapy-induced nausea and vomiting ( CINV) . Methods A total of 78 patients with highly emetogen-ic single day chemotherapy were randomly divided into two groups:trial group ( olanzapine combined with tropisetron, dexamethasone n=40) and control group (Tropisetron Combined with Dexamethasone n=38). The control of acute CINV, delayed CINV and adverse reac-tions were observed. Results The control rates of acute vomiting in trial group and control group were 87. 5% vs 81. 6%, 65. 0% vs 57. 9% in acute nausea, 75. 0% vs 52. 6% in delayed vomiting, 32. 5% vs 13. 2% in delayed nausea. The trial group was better than the control group in delayed vomiting and delayed nausea which there was difference between them (P < 0. 05). There was no statistical differ-ence between the two groups in the incidence of adverse reactions (P>0. 05). Conclusion Olanzapine combined with tropisetron, dexa-methasone for the prevention was significantly better than tropisetron combined with dexamethasone in the control of delayed CINV in pa-tients received highly emetogenic chemotherapy.%目的 观察奥氮平联合托烷司琼、地塞米松预防高致吐风险药物化疗引起恶心、呕吐的临床疗效和不良反应. 方法 采用含高致吐风险药物化疗的78例患者随机分为观察组(奥氮平联合托烷司琼、地塞米松)和对照组(托烷司琼联合地塞米松),观察各组化疗后恶心、呕吐等不良反应的发生情况. 结果 观察组与对照组防治急性呕吐的有效率分别为87. 5%和81. 6%,观察组与对照组防治急性恶心的有效率分别为65. 0%和57. 9%,差异均无统计学意义(P>0. 05);观察组与对照组防治迟发性呕吐的有效率分别是75. 0%和52. 6%,观察组与对照组防治迟发性恶心的有效率分别为32. 5%和13. 2%,差异均有统计学意义(P<0. 05). 两组间不良反应发生率比较,差异无统计学意义(P>0. 05). 结论 奥氮平联合托烷司琼、地塞米松预防高致吐风险药物化疗所致迟发性恶心、呕吐疗效显著,不良反应轻.
