Clinical efficacy of Xiaoyao San combined with Bazhen Decoction in the treatment of insomnia in postoperative breast cancer patients

Objective This study aimed to evaluate the effects of Xiaoyao San combined with Bazhen Decoction on insomnia in patients following breast cancer surgery. Methods A total of 86 patients experiencing insomnia after breast cancer surgery were randomly assigned to either the treatment group or the control group. The treatment group received Xiaoyao San combined with Bazhen Decoction, while the control group was treated with estazolam tablets. The treatment duration was 4 weeks. Pittsburgh Sleep Quality Index (PSQI) scores were assessed before and after treatment. The overall efficacy and incidence of adverse reactions were compared between the two groups. Results PSQI scores in both groups significantly decreased after treatment ( p < 0.05). Total effective rate in the treatment group (93.02%) was higher than that in the control group (86.05%), although the difference was not statistically significant ( p > 0.05). The incidence of adverse reactions in the treatment group (4.65%) was significantly lower than that in the control group (20.93%) ( p < 0.05). Conclusion Xiaoyao San combined with Bazhen Decoction can effectively improve sleep quality in patients with insomnia following breast cancer surgery, demonstrating good clinical efficacy and fewer adverse reactions. Further studies are needed to confirm these findings and explore broader clinical applications.
