硝酸甘油软膏与利多卡因凝胶在肛门病术后换药镇痛中的应用

Nitroglycerin Ointment and Lidocaine Gel for Postoperative Wound Dressing in Anal Disease

为探讨肛门病术后创口换药镇痛的有效方法，将300例肛门病术后患者随机分为治疗A组、治疗B组和对照组各100例。治疗A组换药前创面涂抹硝酸甘油软膏；治疗B组换药前创面涂抹利多卡因凝胶；对照组常规换药，分病种对比观察3组患者疼痛评分、创面愈合时间及不良反应发生情况。结果显示，痔、肛裂术后治疗A组换药使用硝酸甘油软膏各方面指标优于其它两组；肛瘘、肛周脓肿术后治疗B组换药使用利多卡因凝胶各方面指标优于其它两组。结果表明，不同病种术后采用不同的换药前用药可减轻患者痛苦，缩短治疗周期。
