Abstract

Thirty patients with Chronic Obstructive Pulmonary Disease, COPD, undergoing surgery of lower abdomen and inferior limbs were grouped in 3 numerically equal groups. In group I, subarachnoid block was used; in group II, Halothane anesthesia was performed and in group III, the technique was neuroleptanalgesia. In both general anesthesia groups, the patients were ventilated with a tidal Volume of 10 ml/kg, a respiratory rate of 12 breaths per minute and with 3 to 5 cm H2O of PEEP. The diagnosis of COPD was made by the clinical history, chest X-ray and FEV1 less than 70% of Vital Capacity. Arterial blood gases were checked before, during and 1 hour after surgery. The PO2/FIO2 ratio was used in order to evaluate the efficacy of ventilation. Chest X-ray and clinical examination were done preoperatively and in the third postoperative day. The alterations in arterial blood gases were similar in all groups. The changes in the PO2/FIO2 ratio were non significant and similar in the pre, intra and postoperative samples in the 3 groups. All the patients were free of pulmonary complications in the first 3 postoperative days. We believe that the use of PEEP, with a large tidal volume and a low respiratory rate, is efficient enough to prevent the hypoxemia which occurs during the anesthesia.
