口腔癌の全身麻酔手術症例における術後肺合併症のリスク評価

抄録

The present study was performed to investigate risk factors for postoperative pulmonary complications in oral cancer surgery. Between 2007 and 2011, a total of 288 patients underwent oral cancer surgery under general anesthesia in the Department of Oral-Maxillofacial Surgery, Chiba University Hospital. Postoperative pulmonary complications occurred in 44 patients （15.3%）. The results of statistical analysis showed that 14 risk factors were related to pulmonary complications: age, gender, history of chronic obstructive pulmonary disease （COPD）, history of brain disease, history of smoking, preoperative abnormal chest radiograph, preoperative volume of sputum, activities of daily living （ADL）, American Society of Anesthesiologists （ASA） classification, duration of operation, duration of anesthesia, volume of blood loss during surgery, blood transfusion during surgery, and tracheotomy. In addition, we found that activities of daily living, blood transfusion during surgery, and tracheotomy were more strongly related to postoperative pulmonary complications on multivariate logistic regression analysis.
