摘　　要：目的探讨表面麻醉药冷却后用于烧伤创面换药镇痛中的效果。方法选择2009年12月～2010年12月本院收治的Ⅱ度烧伤患者60例,随机分为实验组和对照组,每组各30例。对照组换药前在室温下应用0.5%利多卡因对患者喷涂创面,实验组换药前应用经冷却为10℃的0.5%利多卡因喷涂创面,比较两组患者换药前和喷药后5、10、30、60min时疼痛评分的差异。结果换药前和换药后60min两组患者的疼痛评分比较,均P>0.05,差异无统计学意义;喷药后5、10、30min实验组疼痛评分低于对照组(均P<0.01)。结论表面麻醉药冷却至10℃时喷涂烧伤创面后进行换药,可有效缓解烧伤患者创面换药时引起的疼痛,增加患者舒适度。Objective To investigate the effect of cooled superficial anesthetic agents as dressing changes on burn wounds. Methods 60 patients with phase II burns were divided randomly into control and experimental groups in equal number. In the experimental group, the patients received local anesthesia with 0.5% lidocaine at 10℃ before dressing change. The patients in the control group received the same management at room temperature before dressing change. The two groups were compared at 5 min, 10 min, 30 min and 60 min before and after dressing changes. Results Before and after dressing changes, there were not significant differences at 60 rain in two groups （P 〉 0.05）, but after changing dressings, the pain scores in the experimental group were significantly lower than those of the control group at 5 rain, 10 min and 30 min, respectively （all P 〈 0.01）. Conclusions Superficial anesthetic agents cooled down to 10℃ and used to treat the burn wounds may effectively relieve the pain and reduce complications.
