简介:摘要目的分析七叶皂甙钠联合丹红注射液治疗胫腓骨骨折肢体肿胀的临床疗效。方法选取2015年6月—2017年6月我院收治的闭合性非粉碎性胫腓骨骨折肢体肿胀患者46例为观察组,选取同期我院收治的闭合性非粉碎性胫腓骨骨折肢体肿胀患者43例为对照组,两组患者均予常规治疗,对照组在此基础上予七叶皂甙钠,观察组予七叶皂甙钠联合丹红注射液。比较两组治疗前后患肢与健肢小腿周径差。结果治疗前两组患肢与健肢小腿周径差差异无统计学意义(P>0.05),治疗后第5、7、10天,两组患肢与健肢小腿周径差均较治疗前缩小(P<0.05),且治疗后第7、10天,观察组患肢与健肢小腿周径差小于对照组,差异有统计学意义(P<0.05)。结论七叶皂甙钠联合丹红注射液治疗胫腓骨骨折肢体肿胀,两者共同发挥消除肢体肿胀的效果,疗效优于单用丹红注射液。
