ABSTRACT

Objective To compare the effects of three kinds of dressings (foam dressings,hydrocolloid dressings,homemade gauze dressings)at different periods for preventing nasal and facial pressure ulcers in elderly patients in the intensive care unit with continuous non -invasive ventilation.Methods The study group consisted of 120 patients who were 60 years old in the intensive care unit with continuous non -invasive ventilation.They were randomly divided into A,B,C three groups with random number table.The patients in A group used foam dressings. The patients in B group used hydrocolloid dressings.The patients in C group used homemade gauze dressings.In the first week and the second week,through comparing the incidence of pressure ulcers,we compared the prevention effect of three kinds of dressings on nasal and facial pressure ulcers.Results In the first week,there was no statistical difference about the incidence of pressure ulcers among the three groups(χ2 =2.124,P =0.346).In the second week,the incidence of pressure ulcer of A group was obviously lower than B group and C group(χ2 =5.271,P =0.038).Conclusion When we nurse elderly patients in the intensive care unit with continuous non -invasive ventilation,within 7 days,we can use any one of three kinds of dressings to prevent nasal and facial pressure ulcers. But 7 days later,we should better use foam dressings.
