More than 300 million major operations are performed worldwide each year, and older patients account for about a third of elective operations. Compared with young people, the elderly are more prone to postoperative complications due to age-related degeneration of the physiological functions of various organs and tissues. Postoperative pulmonary complications, including pneumonia, atelectasis, and respiratory failure, are common. Even mild pulmonary complications can lead to the prolonged hospital stay and increased postoperative mortality.~Although there have been many studies on postoperative lung complications, there have been few studies on elderly patients. In our country, the real incidence data of elderly patients after a perioperative period of pulmonary complications, the lack of effective prevention, intervention measures, and targeted prevention and treatment technology, these reasons lead to the clinical diagnosis and treatment of elderly patients after a perioperative period of pulmonary complications are very difficult. Therefore, the research team intends to verify the established prediction model of postoperative pulmonary complications and compare the incidence of postoperative pulmonary complications in elderly patients before and after using the prediction model.
This study aims to verify the prediction model of postoperative pulmonary complications by collecting clinical information on elderly patients. In addition, the incidence of postoperative pulmonary complications in elderly patients before and after using the prediction model was compared.
