TIMING OF EXTUBATION AFTER ESOPHAGECTOMY

Ventilatory support for 24 h after surgery is standard practice in many units after oesophagectomy, especially for patients in whom respiratory problems are anticipated. Weaning difficulties may occur, however, and there is increasing evidence that mechanical ventilation is associated with alveolar trauma. A deliberate change in policy was instituted in the authors' unit in January 1990 to make early extubation mandatory in all patients undergoing elective oesophagectomy, apart from those in whom serious perioperative problems were encountered. The present study compared two sets of patients: group I (n=36) underwent oesophagectomy in the year before the policy change and group 2 (n=45) oesophagectomy in the year after. The two groups were similar in age, sex and respiratory risk factors. Early extubation was carried out in 38 patients in group 2 compared with eight in group 1 (P<0.001). Only two patients in group 2 required prolonged ventilation compared with ten in group I (P<0.005). No patient in group 2 required reventilation compared with seven in group I (P<0.005), and no patient in group 2 who had undergone early extubation required delayed ventilation. The mean ventilation time and length of stay in the intensive care unit were significantly reduced following the policy change. Early extubation after elective oesophagectomy is an attainable goal and results in a significant reduction in both the morbidity rate and cost of surgery.
