Hemodynamic and Catecholamine Stress Responses to Insertion of the Combitube[registered sign], Laryngeal Mask Airway or Tracheal Intubation

Abstract

In this study, we showed that the hemodynamic and catecholamine stress responses after insertion of the Combitube (Kendall-Sheridan Catheter Corp., Argyle, NY) were significantly higher compared with laryngeal mask airway or endotracheal intubation. We conclude that the increased stress response to insertion of a Combitube may represent a serious hazard to patients with cardiovascular disease.
