Multivariate Analysis Of Perioperative Risk Factors Associated With Postoperative Pulmonary Complications In Aged80Years Or Older Patients Undergoing Thoracic Surgery

Objective: To explore the correlation between the perioperative riskfactors and postoperative pulmonary complications in80years or olderpatients undergoing thoracic surgery. Methods: Forty-one patients withbenign lung disease who underwent thoracic surgery were included in thisretrospective analysis. Medical records of all patients were reviewed tomeasure predefined pre-and intraoperative risk factors and postoperativeoutcomes. Univariate and multivariate analysis was performed toinvestigate the risk factors of pulmonary complications among the patients.Results: Postoperative pulmonary complications were seen to occur in21of the41patients (51.2%), and the most common complication waspneumonia (13cases), followed by atelectasis (5cases), hypoxemia (2cases), pneumothorax (1cases). Multivariate logistic analysis showed thatthe BMI＞24, smoking index＞400, FEV1%＜65%, MVV%＜60%, longer duration of surgery and albumin level＜30g/L were the valuable riskfactors for prediction of postoperative pulmonary complications.Conclusions: Our data indicate that BMI, smoking index, FEV1%, MVV,longer duration of surgery and albumin level may be useful to identify highrisk patients for pulmonary complications development and adverseoutcomes.
