Abstract: Objective To investigate the application of environment-friendly tracheotomy waterproof pad to patient care after tracheotomy.Methods Forty patients who underwent tracheotomy in the Department of Otolaryngology of Tongji Hospital,Tongji University School of Medicine from January 2015 to March 2017 were enrolled in this study.All subjects were randomly divided into an observation group and a control group with 20 cases in each group.The control was treated with regular moist gauze cover and aerosol inhalation,and the observation was additionally treated with environment-friendly waterproof pad.Comparisons were made between the two groups in the post operative usage rate of moist gauze during hospital stay,dampness of collar and gauze on the incision after aerosol inhalation treatment,and surrounding skin condition after tracheotomy.Results The usage rate of moist gauze in the control group was 70%,and the rate in the observation group was 85%.After aerosol inhalation,the incidence rate of dampness of collar and gauze was 95% for the control group and 15% for the observation group.In the control group,the incidence rate of skin swelling surrounding incision was 20%,and such symptom did not occur in the observation group.Conclusion Environment-friendly waterproof pad could increase patients’ adherence to moist gauze,avoiding damp collar and and decreasing skin swelling surrounding incisions.
