title: [Tramadol during the postoperative period].
abstract: The effect of tramadol, a new synthetic opioid, on respiration and circulation was examined in 42 patients during the postoperative period after upper abdominal surgery. Pulmonary disorders were present in some patients. Tramadol did not affect the haemodynamic parameters; but the tidal volume increased and the respiratory rate fell. Forced vital capacity, which was reduced after the operation, increased, possibly due to the analgesic effect of tramadol. The drug appears to be a suitable choice during the postoperative period, especially in patients with pulmonary disorders.
