[Establishment and application of a clustered management plan for pulmonary care of massive burn casualties]

Objective: To establish a clustered management plan for pulmonary care of massive burn casualties (hereinafter referred to as the clustered management plan for pulmonary care), and to explore its application effects. Methods: (1) A clustered care intervention group was established, including the medical and nursing staff from the Department of Burns and Plastic Surgery, Department of Respiratory Medicine, and Department of Infection Control at the Fourth Medical Center of PLA General Hospital (hereinafter referred to as our hospital). Four major links, including pulmonary care assessment, chest and lung physical therapy, artificial airway management, and specialized infection control were sorted out according to the key points and difficulties in pulmonary care for massive burn casualties. Evidence-based nursing methods were employed to retrieve articles related to the above-mentioned four links from PubMed, Chinese Journal Full-Text Database, VIP Database and Wanfang Data using terms of " mass burn, respiratory management and airway management" and terms of ",," , and the clustered management plan for pulmonary care was established based on reading and discussion in combination with clinical practice and experience. (2) In this non-randomized controlled study, the clustered management plan for pulmonary care was applied to 73 massive burn patients (48 males and 25 females, aged 32 (25, 38) years) who were admitted to our hospital from January 2016 to December 2019 and met the inclusion criteria, and they were included into the clustered care group; 43 massive burn patients (25 males and 18 females, aged 35 (17, 45) years) who were admitted to our hospital from January 2013 to December 2015, received routine care and met the inclusion criteria were retrospectively included into routine care group. The pulmonary infection rate and mortality of patients in the two groups were recorded during the hospital stay. Data were statistically analyzed with chi-square test, Mann-Whitney U test, and independent sample t test. Results: (1) The clustered management plan for pulmonary care included a total of 12 specific measures covering four aspects of pulmonary care. The contents in pulmonary care assessment clearly stated to include the previous medical history, history of injury, respiratory status, hoarseness, pulmonary auscultation, etc. Chest and lung physical therapy included how to guide patients to effectively cough and do pursed lip breathing and abdominal breathing exercise, etc. Artificial airway management specified the preparation for the establishment of artificial airway at clinical reception, the observation index and frequency after tracheotomy, the method of humidification, the method and frequency of sputum suction, and the management of mechanical ventilation, etc. Specialized infection control required to strengthen hand hygiene and ventilator management. (2) The pulmonary infection rate and mortality of patients in the clustered care group were 2.74% (2/73) and 4.11% (3/73), respectively, significantly lower than 25.58% (11/43) and 18.60% (8/43) in routine care group (χ(2)=11.986, 5.043, P<0.05 or P<0.01). Conclusions: The clustered management plan for pulmonary care developed for massive burn casualties focuses on the major links and key points. The measures are systemic and comprehensive, simple but precise, and highly operable, covering the entire process of massive burn care, hereby reducing the pulmonary infection rate significantly and improving the success rate of treatment.
