Objective To explore the application effect of nosting barrier film in the skin nursing of laryngeal carcinoma patients with trachea cannula after surgery.MethodsTotally 90 cases of laryngeal cancer patients after radiotherapy with tracheal cannula,were randomly divided into three groups,with 28 cases in the control group,33 cases in the dressing group,and 29 cases in the skin protective film group. Patients in the control group were treated with basic nursing method including using saline to clean plastic casing,cleaning and disinfecting skin,using sterile gauze to cover the field of radiation skin and plaster fixation;dressing group adopted Comfeel hydrocolloid dressings on the basis of basic nursing method;skin protective film group adopted Genetime spray skin protective film to protect skin of radiation field on the basis of basic nursing. After radiotherapy,the incidence of skin injury,severity of skin injury,patient comfort,and the time and times of changing skin dressing everyday were observed and compared among three groups.Results The incidence of radiation skin injury in the skin protective film group (6.89%) and dressing group (15.15%),were all lower than the control group (50%) (χ2=16.75,P<0.05);the times of changing skin dressing everyday in the skin protective film group (4.28±0.53) times/d and the dressing group (4.52±0.76) times/d,were lower than the control group (6.04±1.35) times/d (Hc=32.65,P<0.05);patient comfort in the skin protective film group and the dressing group was superior to the control group (Hc=22.42,P<0.05);the time of changing skin dressing in the skin protective film group (10.40±1.35) min,was less than the dressing group (14.09±1.27) and the control group (12.35±1.28) min (F=85.87,P<0.05).Conclusions The skin protective film can effectively reduce the incidence of skin injury in patients with laryngeal cancer and radiotherapy,improve patient comfort,reduce the labor time of nurses,and improve the quality of care and efficiency.
