Abstract: Objective To investigate the effect of one-piece anal ostomy bag combined with negative pressure suction device on the intake status of enteral nutrition(EN) and incontinence dermatitis(IAD) in the elderly patients with severe incentinence. Methods A total of 76 cases of elderly patients with severe fecal incontinence admitted in our department from 2018 to 2019 were selected, and were divided into research group and control group with 38 cases in each group. The EN programme was conducted in all patients according to the doctor's advice.One-piece anal ostomy bag combined with negative pressure suction device was used for fecal collection in the research group; The control group received local skin cleaning and protection standard cleaning, 3M ostomy powder and skin protective film. Results The incidence rate of IAD was significantly higher and the rate of nutritional compliance, the level of PAB after nutrition intake were lower in the recearch group than those in the control group (P < 0.05).The nursing workload and nurse acceptance were all significantly improved in the research group than those in the control group(P<0.05). Conclusions One-piece anal ostomy bag with negative pressure suction device can improve the nutritional status of patients with severe fecal incontinence, reduce the incidence rate of IAD, and improve the quality of care.
