Effects of lornoxicam on the hemodynamic and catecholamine response to laryngoscopy and tracheal intubation

Abstract

Laryngoscopy and tracheal intubation are associated with hemodynamic responses that might increase morbidity and mortality in some patients. Lornoxicam is a nonsteroidal anti-inflammatory drug, which, when added to fentanyl, successfully attenuated the pressor response of intubation. The aim of this study was to evaluate the effect of lornoxicam on the hemodynamic response and serum catecholamine levels following laryngoscopy and tracheal intubation. Fifty adult patients scheduled for general anaesthesia with endotracheal intubation were enrolled in this randomized, double-blind placebo-controlled study. They were divided into two equal groups to receive intravenously either lornoxicam 16mg or placebo 30min before surgery. Mean arterial pressure and heart rate were recorded before and after induction of anaesthesia, and every minute after intubation for 10min. Serum catecholamine levels were measured before induction and 1min after intubation. After induction, there was a significant decrease in blood pressure in both groups. In the first 3min after tracheal intubation, a significant increase in the hemodynamic parameters and in the serum norepinephrine level was observed in the control group. Lornoxicam 16mg attenuates the pressor response to laryngoscopy and intubation of the trachea.
