摘要目的：研究水凝胶敷料用于持续无创正压通气患者眼部的应用效果。方法选择持续使用无创呼吸机辅助通气治疗的呼吸衰竭患者47例，按随机数字表法将患者随机分为试验组（ n＝22）和对照组（ n＝25）。对照组给予常规护理，试验组在此基础上，使用无创通气时即给予眼部敷贴水凝胶敷料，观察两组患者的临床护理效果。结果使用无创通气后第7天，试验组患者眼部舒适度评分为（76．91±3．02）分，对照组为（72．56±2．86）分，差异有统计学意义（t＝5．067，P＜0．01）；试验组患者发生异物感3例、眼睑肿胀1例，对照组分别为11，9例，差异均有统计学意义（χ2值分别为5．159，5．162；P＜0．05）。结论持续无创呼吸机辅助通气患者在治疗期间敷贴水凝胶敷料可增加患者舒适度、减少眼部不适等症状的发生。

abstractsObjective To observe the effects of hydrogel dressing on ocular in patients with continuous non-invasive positive pressure ventilation .Methods A total of 47 patients with continuous noninvasive ventilation were divided into observation group ( n =22 ) and control group ( n =25 ) randomly .Patients in observation group were putting the hydrogel dressing on ocular when using non -invasive ventilation , while control group received normal nursing .Then,clinical effects were observed and compared .Results The comfort level scores of observation group was significantly higher than that of control group at 7 days after using non-invasive positive pressure ventilation [(76.91 ±3.02) vs(72.56 ±2.86); t =5.067,P<0.01)].The number of patients with foreign body sensation (3 vs 11) and ocular dryness (1 vs 9) in observation group was significantly lower than that in control group (χ2 =5.159,5.162,respectively;P <0.05).Conclusions Putting the hydrogel dressing on ocular of patients with non-invasive ventilation may increase patient′s comfort and reduce the incidence of ocular discomfort .
