文摘目的:探讨解郁合欢膏治疗卒中后抑郁(Post-stroke Depression,PSD)的临床疗效。方法:选择2018年7月1日-2019年6月30日在南宁市中医医院脑病科门诊及住院的PSD患者96例作为研究对象,以随机数字表法简单随机分组为两组,剔除脱落后对照组45例,观察组46例。对照组在常规治疗基础上口服盐酸帕罗西汀,观察组口服解郁合欢膏,疗程均为8周,分别于治疗前、治疗后使用汉密尔顿抑郁量表(Hamilton Depression Scale,HAMD)、改良Bathel指数(Barthel Index,BI)、美国国立卫生研究院卒中量表(National Institutes of Health Stroke Scale,NIHSS)评定疗效,以及不良反应发生情况。结果:治疗后观察组总有效率高于对照组,两组患者HAMD评分、NIHSS评分比较均低于治疗前(P<0.05),BI评分高于治疗前(P<0.05),且观察组优于对照组,差异有统计学意义(P<0.05)。两组均未发生严重药物不良反应。结论:解郁合欢膏治疗卒中后抑郁可改善患者抑郁症状,提高生活质量,有较好的治疗效果,且患者不良反应发生率较低。
