How effective are ondansetron tablets? Select 104 patients with lung cancer, all of whom received chemotherapy. They were randomly selected by digital method. 52 cases in each group were set as the control group and the research group. The research group was treated with thalidomide combined with ondansetron, and the control group was treated with ondansetron. The treatment effects, nausea and vomiting prevention effects, and adverse reactions were compared between the two groups. Results: The incidence of nausea and vomiting in the study group was 90.38%, 90.38% were higher than those in the control group, and the difference was statistically significant (x=14.457, 13.128, P<0.05). The treatment effect was 94.23% better than that in the control group, the difference was statistically significant (x2=5.282, P<0.05). There was no statistically significant difference in adverse reactions compared with the control group (x=0.000, P>0.05). Conclusion: The use of thalidomide combined with ondansetron in patients with lung cancer chemotherapy can effectively reduce the incidence of nausea and vomiting, effectively prevent the occurrence of nausea and vomiting, and have low other adverse reactions. The treatment effect is obvious, safe and reliable, and improves the quality of life, so it can be clinically promoted and applied.
