Determinants of perioperative morbidity and mortality after pneumonectomy.
BACKGROUND
Pneumonectomy remains a relatively high-risk procedure. However, the underlying mechanism is still unknown. Thus, the effort to find out predisposing factors for surgical risks continues. We investigated the effect of both water-load control and sampling lymphadenectomy technique on perioperative morbidity and mortality after pneumonectomy.


METHODS
A hundred and three consecutive patients undergoing simple pneumonectomy were included in the prospective study. Pneumonectomy was performed for lung cancer in 92 patients and for benign diseases in 11 cases; 81 patients were male and 22 female, and the mean age was 53.4 +/- 11.4 years. Both sampling and completion lymphadenectomy techniques were used randomly. Water-load was carefully limited to values as low as possible, depending on stable hemodynamics during and after operation.


RESULTS
There were no deaths, and none of the patients needed postoperative mechanical ventilation. Major complications included dyspnea in 9 patients and supraventricular arrhythmias in 13 patients. Completion lymphadenectomy increased morbidity in both right and left pneumonectomy.


CONCLUSIONS
Both water-load limitation and sampling lymphadenectomy technique may decrease morbidity and mortality after pneumonectomy.
