摘要目的：观察黄瓜预防术后禁食患者口唇干裂及口腔溃疡的临床疗效，降低术后禁食致口唇干裂及口腔溃疡的发生率。方法将124例术后禁食患者按入院单双日随机分为观察组（ n＝62）和对照组（n＝62），对照组患者术后禁食期间用温开水或液体石蜡涂口唇，用0．9％氯化钠溶液或复方氯己定溶液口腔护理；观察组在对照组的基础上加用黄瓜片贴嘴唇，黄瓜汁漱口；比较两组患者术后禁食期间口唇干裂及口腔溃疡发生情况。结果观察组口唇干裂及口腔溃疡发生率为4．84％，低于对照组的43．55％，两组比较差异有统计学意义（χ2＝90．26，P＜0．01）。观察组患者口唇干裂及口腔溃疡程度也低于对照组。结论黄瓜预防术后禁食患者致口唇干裂及口腔溃疡效果良好，适合临床推广。

abstractsObjective To observe the clinical efficacy of cucumber on preventing chapped lips and oral cavity ulcer caused by fasting after surgery.Methods A total of 124 fasting patients were randomly divided into experimental group and control group on average.The control group during the period of fasting were painted lips or gargled with warm boiling water or mineral syrup while the experimental group during the period of fasting were laid with cucumber slices or gargled cucumber juice.The incidence of chapped lips and oral cavity ulcer during the fasting period in two groups had been compared.Results The incidence rate of chapped lips and oral cavity ulcer in the experimental group was 4.84%, which was lower than that in the control group(43.55%) with statistical significance (χ2 =90.26,P<0.01).The degree of chapped lips and oral cavity ulcer in the experimental group was lower than that in the control group as well.Conclusions Utilization of cucumber for fasting patients is effective to prevent chapped lips and oral cavity ulcer.
