Abstract:
Objective To analyze the risk factors of hypoxemia after coronary artery bypasses grafting (CABG) along with cardiopulmonary bypasses and to understand the regular pattern and characteristics of hypoxemia after CABG. Methods The risk factors of hypoxemia were studied by one way analysis and multivariate logistic regression analysis in 86 patients with hypoxemia after CABG along with cardiopulmonary bypass. Results One way analysis indicated that hypoxemia after CABG along with cardiopulmonary bypass was related to senility ( ≥ 65 years ), smoking history, diabetes mellitus, chronic obstructive pulmonary disease ( COPD), left ventricular ejection fraction ( LVEF ＜ 45 % ), obesity before operation, transfusion ( ≥ 1000 ml );multivariate analysis indicated that pulmonary dysfunction before operation, longer extracorporeal circulation time ( ≥2 h), hypoalbuminemia and pulmonary infection were independent risk factors of hypoxemia after CABG along with cardiopulmonary bypass. Conclusion Multiple risk factors contributed to hypoxemia after CABG along with cardiopulmonary bypass. Increase the awareness of risk factors of perioperative hypoxemia may guide the prevention and treatment, even alleviate or avoid the hypoxemia postoperatively.
