| Description | Journal: Shock Adenosine triphosphate-sensitive potassium channels are important regulators of arterial vascular smooth muscle tone and are implicated in the pathophysiology of catecholamine tachyphylaxis in septic shock. The present study was designed as a prospective, randomized, double-blinded, clinical pilot study to determine whether different doses of glibenclamide have any effects on norepinephrine requirements, cardiopulmonary hemodynamics, and global oxygen transport in patients with septic shock. We enrolled 30 patients with septic shock requiring invasive hemodynamic monitoring and norepinephrine infusion of 0.5 mu g center dot kg(-1 center dot)min(-1) or greater to maintain MAP between 65 and 75 mmHg. In addition to standard therapy, patients were randomized to receive either 10, 20, or 30 mg of enteral glibenclamide. Systemic hemodynamics, global oxygen transport including arterial lactate concentrations, gas exchange, plasma glucose concentrations, and electrolytes were determined at baseline and after 3, 6, and 12 h after administration of the study drug. Glibenclamide decreased plasma glucose concentrations in a dose-dependent manner but failed to reduce norepinephrine requirements. None of the doses had any effects on cardiopulmonary hemodynamics, global oxygen transport, gas exchange, or electrolytes. These data suggest that oral glibenclamide in doses from 10 to 30 mg fails to counteract arterial hypotension and thus to reduce norepinephrine requirements in catecholamine-dependent human septic shock |
