Objective To investigate the effect of early application of hydrocolloid dressings for preventing phlebitis in patients with PICC.Methods A total of 62 cancer patients with PICC in our hospital between January 2014 and November 201 5 were chosen and randomly divided into an observation group and a control group,each of 31.The observation group was given hydrocolloid dressings of 10cm×10cm after placing PICC,5 to 6cm above the insertion site and parallel to the venepuncture.The hydrocolloid dressing was replaced once a week.The control group was given a 1 1cm× 12cm transparent dressing and replaced at the same frequency.Both groups were given routine nursing for patients with PICC.Then the incidence of mechanical phlebitis was observed. Results In the observation group,1 mechanical phlebitis of class I was observed in the observation group,accounting for an incidence was 3.23%.However,7 patients were found of mechanical phlebitis (including 5 of class I and 2 of class II)in the control group,with an incidence of 22.58%. Therefore,the incidence of mechanical phlebitis in the observation group were significantly lower than that in the control group.Conclusions The early application of hydrocolloid dressings can be effective in preventing mechanical phlebitis induced by PICC.%目的：观察早期应用水胶体敷料预防经外周静脉穿刺中心静脉置管(peripherally in-serted central catheter,PICC)术后机械性静脉炎的效果。方法选取2014年1月-2015年11月行 PICC 治疗的肿瘤患者62例,随机将其分为对照组和观察组各31例。观察组患者置管后在置管部位上方5~6cm 处沿静脉穿刺走向覆盖10cm×10cm 的水胶体敷料,7d 更换1次；对照组患者置管后给予11cm×12cm 透明敷贴固定,7d 更换1次。2组患者均按 PICC 护理常规进行护理,观察2组患者机械性静脉炎的发生情况。结果观察组患者中仅有1例发生 I 级静脉炎,发生率为3.23%；对照组患者中7例发生静脉炎,其中5例为 I 级静脉炎,2例为 II 级静脉炎,发生率为22.58%。观察组患者静脉炎发生率显著低于对照组。结论早期应用水胶体敷料能有效预防 PICC置管术后机械性静脉炎的发生。
