Clinical analysis of early postoperative hypoxemia

Abstract

Objective To study high risk factors of early postoperative hypoxemia and its prevention. Methods Patients admitted to SICU suffering from postoperative hypoxemia in 24 h during recent 2 years were taken as case group. Those who did not suffering from postoperative hypoxemia during the same period drawn by proportion of 1:2 randomly were taken as control group. The surgical operation categories and directive cause of hypoxemia were analyzed in case group. Then the high risk factors were deduced and were investig ated with single factor analysis and Logistie multiple regression analysis. Results Surgical operation categories in case group were mainly thoracic operation (33.78%) and upper abdominal surgeries (24.32%). Directive cause of hypoxemia included the aggravation of pulmonary primary disease(17.57%), the complication of thoracic operation (24.32%), improper disposal of perioperative management (18.92%) and so on. Analysing factor indicated that a long history of smoking,pulmonary primary disease,critically ill patients, complication of thoracic operation, a great quantity transfusion and insufficient respiratory supporting were concerned with early postoperative hypoxemia. Logistic multiple regression found that pulmonary primary disease, critically ill patients, complication of thoracic operation and insufficient respiratory supporting could increase the risk of hypoxemia remarkably (P<0.05). Conclusions Pulmonary primary disease, critically ill patients, complication of thoraeie operation and insufficient respiratory supporting are tightly concerned with early postoperative hypoxemia. Corresponding measures should be taken for its prevention. Key words: Postoperative hypoxemia; High risk factors; Single factor analysis; Logistic multiple regression analysis
