[目的]探讨短波紫外线治疗仪治疗急性白血病住院患者化疗后口腔黏膜炎(OM)的临床疗效.[方法]按照入院先后顺序不同将接受化疗后出现OM的急性白血病住院患者分为观察组和对照组,对照组采用亚叶酸钙、维生素B12漱口液漱口、表面喷涂金因肽、金喉健等治疗;观察组在对照组的基础上加用ZYY-9增强型短波紫外线治疗仪进行照射治疗.观察两组在治疗14d后OM的治疗效果.[结果]治疗14d后,观察组痊愈率(89.3%)明显高于对照组痊愈率(64.3%);观察组在疼痛感消失时间、溃疡面积缩小50%和溃疡面愈合所需时间上明显短于对照组,差异均有统计学意义(均P<0.05).[结论]短波紫外线治疗仪可提高OM的痊愈率,缩短OM的痊愈时间,使用安全、方便,患者易于接受,值得临床推广应用.“,”[Objective]To explore the curative effect evaluation of short-wave ultraviolet ray therapy for oral mucositis (OM)with acute leukemia patients.[Methods]Acute leukemia patients with oral mucositis were divided into the observa-tion group and the control group according to the order of admission.Patients in the control group were treated by conven-tional methods,while patients in the observation group received irradiation treatment by ZYY-9 enhanced short-wave ultra-violet ray therapy apparatus in addition to conventional treatment.The therapeutic effect for OM in the two groups was ob-served within 14 days.[Results]The recovery rate of the observation group was 89.3% which was obviously higher than that of the control group(64.3%)within 14 days,and the difference was statistically significant(P <0.001).In the ob-servation group,the average time required for the disappearance of pain,the 50% reduction in ulcer area of OM and oral mucositis healing time were significantly shorter than those in the control group with statistically significant difference(P<0.001).[Conclusion] Short-wave ultraviolet irradiation treatment can obviously improve the recovery rate of OM and shorten its healing time.The instrument is convenient and safe to use with broad clinical popularization and application.
