Postoperative pulmonary complications in patients with preoperative lung disease.
A prospective study was carried out on the incidence of pulmonary complications in 728 patients who underwent major surgical procedures at a reputed hospital in New Delhi. These patients were preoperatively assessed on the basis of history, clinical examination and bedside pulmonary function tests including PEFR, VC, FVC and FEV1. On the basis of these criteria, 212 patients had significant preoperative pulmonary disease, while 516 had normal lung functions. Postoperative pulmonary complications developed in 7.69 per cent of the patients. They were more frequent in smokers (P < 0.001) and in those with preoperative pulmonary dysfunction (P < 0.001). Their incidence was greater following thoraco-abdominal and musculoskeletal and miscellaneous operations compared to lower abdominal surgery (P < 0.001). The incidence was also higher following exposure to general anaesthesia compared to regional anaesthesia (P < 0.05). Pneumonia and atelectasis were the most common postoperative pulmonary complications. It was observed that the recovery of pulmonary functions was delayed in patients who developed postoperative pulmonary complications.
