Résumé
Objective To apply the concept of evidence-based nursing to the practice of non-invasive ventilation,and to introduce the method of using self-made pressure-resistant cap cotton cover and its application effect.Methods Fifty patients on non-invasive ventilation admitted to intensive care unit (ICU) of Harrison International Peace Hospital Affiliated to Hebei Medical University from September 2017 to April 2018 were enrolled as observation group.By retrieved the relevant literature at home and abroad to look for clinical evidence,the concept of evidence-based nursing care program was formulated and implemented,and self-made pressure-resistant cap cotton cover was used to prevent facial pressure sores in patients on non-invasive ventilation.Forty non-invasive ventilation patients admitted from January to August in 2017 were enrolled as the historical control group,and conventional nursing was conducted by using traditional hydrocolloid dressings to prevent pressure ulcers.The incidence of facial pressure ulcers,ocular complications,dressing replacement time and cost were compared between the two groups.Results All patients were enrolled in the final analysis.The incidence of pressure ulcers in the observation group was significantly lower than that in the control group [4.0％ (2/50) vs.22.5％ (9/40),P ＜ 0.05],and the incidences of ocular complications such as eyelid swelling [2.0％ (1/50) vs.5.0％ (2/40)],conjunctival congestion [2.0％ (1/50) vs.5.0％ (2/40)] and irritant keratitis [0％ (0/50) vs.7.5％ (3/40)] were also significantly lower than those in the control group (P ＜ 0.05).Because the pressure-resistant cap cotton cover made by ourselves was easy to be replaced at any time,the interval time of dressing change in the observation group was significantly shorter than that in the control group (minutes:1.5 ± 0.5 vs.2.0 ± 0.5,P ＜ 0.05).In addition it could be cleaned,used alternately,and the cost was low,so the dressing cost in the observation group was significantly lower than that in the control group (Yuan:30±10 vs.123±20,P ＜ 0.01).Conclusion The application of self-made pressure-resistant cap cotton cover could obviously reduce the occurrence of complications such as facial pressure sores in patients on non-invasive ventilation.
