Abstract body: Bankgroud: This study aimed to provide an overview of characteristic and regularity of mechanical ventilation, approach methods and decision of respiratory care in critically injured patients who were admitted to the West China Hospital of Sichuan University in the “5.12” Wenchuan earthquake. Methods: Retrospective analysis of the medical records of 127 critically injured earthquake patients.A total of 127 patients with earthquake related injures and illness admitted to ICU of our hospital were included and divided into two main groups: 1. Without mechanical ventilation n = 22, 2. With mechanical ventilation n = 105. Patients’demographic data, age, sex, original injury, basical disease, complications and length of mechanical ventilation were analyzed retrospectively. Results: In total 127 critical patients with earthquake related injures and illness: the rate of mechanical ventilation was 82.68%, and the mortality among these mechanically ventilated patients was 10.58%, while all critical patients without mechanical ventilation patients were cured. Multivariate logistic regression analysis revealed that chest injury, complications of pulmonary infection, sepsis, shock, renal failure were independent risk factors for them requiring mechanical ventilation; multivariate linear regression analysis revealed that chest injury, cervical trauma, cardiopulmonary diseases, lung infection, sepsis, shock and renal failure were risk factors of influencing mechanical ventilation time. Fifteen critical injury patients undergoing mechanical ventilation were admitted to ICU during 48-72 hours after the earthquake, and that peaked after 21 days,there were 72 critical patients and 44 patients undergoing mechanical ventilation in ICU. Conclusion: Large number of patients were continuously admitted to ICU from the third day that peaked during the third week after the major earthquake. Early reasonable deploy and use of respiratory therapy equipments, the rapid treatment of the critically injured victims, and preventing complications should be done to improve the success in curing rate as well as shorten the time of mechanical ventilation. Key words: earthquake, trauma patients, mechanical ventilation, respiratory care Sponsored Research - None
