Brief Summary
This study aims to collect perioperative diagnosis and treatment information of patients undergoing abdominal surgery at plateau and plain areas , collect blood and others samples for laboratory testing when necessary, analyzing the data to clarify the incidence and risk factors of pulmonary complications in patients undergoing abdominal surgery at different altitudes, so as to reduce the risk of pulmonary complications and even death in clinical practice.
