Effect of Cough Machine Assistance and Care Bundle Combined Therapy on Burned Patients With Moderate To Severe Inhalation Injury

To investigate the effectiveness of cough machine assistance combined with care bundle on mental resilience and self-efficacy on burned patients with moderate to severe inhalation injury. Totally 98 burned patients with moderate to severe inhalation injury from April 2021 to April 2022 were enrolled in this retrospective analysis. They were divided into the control group (n = 49, conventional therapy) and combined-therapy group (n = 49, cough machine assistance and care bundles). The mental resilience, posttraumatic growth, and self-efficacy were conducted. The arterial blood gas analysis indicators and incidence of pulmonary infection were also evaluated. The length of hospital stay in combined-therapy group was significantly less than that of control group. There was no difference of pulmonary infections between two groups before treatment. However, the incidence of pulmonary infection in the combined-therapy group was significantly lower. After the therapy, the combined-therapy group showed significantly higher partial pressure of oxygen, and lower levels of oxyhemoglobin saturation and partial pressure of carbon dioxide compared with the control group. The evaluation with the mental resilience, posttraumatic growth, and self-efficacy after the therapy, indicated that the patients in the combined-therapy group had significantly higher scores of optimism, strength, tenacity, relating to others, new possibilities, personal strength, appreciation of life and spiritual change, and self-efficacy. The combined therapy with cough machine assistance and care bundles can effectively improve the mental resilience and self-efficacy level of burned patients with moderate to severe inhalation injury, showing potential for possible clinical applications.
