Introduction: Insertion of endotracheal tubes, especially large and relatively inflexible double-lumen tubes, provokes cardiovascular and humoral responses which can cause complications. Bronchial blockers, combined with conventional single-lumen tubes (SLT), serve as alternatives to double-lumen tubes (DLT) and may provoke less hemodynamic response.
Methods: Forty adults scheduled for elective thoracic surgery requiring single-lung ventilation were randomly assigned to DLT or SLT combined with EZ-Blocker (EZ), a bronchial blocker. Heart rate and arterial blood pressure were recorded before induction of anesthesia, before laryngoscopy, after laryngoscopy, and one minute after intubation. Epinephrine, norepinephrine, and cortisol serum concentrations were assessed one minute after intubation.
