Abstract: ［Abstract］Objective To explore the effect of 3M liquid dressing on prevention of contact dermatitis in PICC patients with evidence-based nursing. Methods Forty PICC patients admitted to hospital from January to June 2018 were selected as control group， and routine PICC maintenance was performed. 40 PICC patients admitted to hospital from July to December 2018 as observation group.After disinfection by routine method， we apply a layer of 3M liquid dressing. After drying， apply aseptic transparent dressing， maintain it every seven days， and replace the bleeding fluid in time. The incidence of contact dermatitis， the frequency of dressing change and the maintenance cost were compared between the two groups. Results There were 1 case of dermatitis （mild） in the observation group and 11 cases of dermatitis in the control group （8 cases of mild dermatitis， 2 cases of moderate dermatitis and 1 case of severe dermatitis）. There was a significant difference in the incidence of mild and moderate dermatitis （P < 0.05）. The maintenance times and total maintenance cost of PICC in the observation group were lower than those in the control group （P < 0.05）. Conclusion The use of 3M liquid dressing can reduce the incidence of contact dermatitis， improve the comfort of patients with PICC， reduce the expense， reduce the workload of nurses changing dressing， and effectively improve the clinical outcome of patients.
