Background And ObjectiveThis study was performed to identify risk factors for complications and in-hospital mortality associated with pneumonectomy.MethodsThe influence of fluid balance during anaesthesia was evaluated, taking into account the patient's age, gender and body mass index, smoking habits, history of pulmonary or cardiac disorders, the site of pneumonectomy and duration of anaesthesia. One-hundred-and-seven patients undergoing elective pneumonectomy were included in the study.ResultsA total of 31 patients (29%) suffered from one or more postoperative complications, seven (22.4%) of these had severe dysrhythmias, six (19.6%) had pulmonary complications and three (9.3%) had cardiovascular complications. The overall mortality rate was 10.3%.ConclusionsBased on logistic regression analysis, our data indicate the following risk factors for postoperative complications: positive fluid balance exceeding 4000 mL during anaesthesia (pulmonary complications and mortality), body mass index < 17 or > 25 kg m(-2) (severe dysrhythmias), or history of chronic heart disease (pulmonary complications). Thirteen patients (12.4%) suffered from a fluid balance > 4000 mL during anaesthesia. Regression analysis indicated that fluid balance exceeding 4000 mL was associated with a higher risk of postoperative complications than blood loss exceeding 1000 mL and to be the strongest risk factor for postoperative pulmonary complications and in-hospital mortality. Further trials estimating the effect of restrictive fluid regimens and the use of vasopressors for blood pressure control during anaesthesia must be carried out.
