Revisited: Haemodynamic Instability and Endocrine Response During Endotracheal Tube-Placement. A Prospective, Randomized Trial Using Topical Lidocaine and a Lightwand

摘要

Endotracheal intubation via direct laryngoscopy frequently provokes cardiovascular side-effects. Although usinga lightwand intubation device reduces laryngeal stimulation, previous reports indicated a similar stress response comparedto classical laryngoscopy. We hypothesized that endotracheal tube (ET) placement itself elicits haemodynamic instabilityand that topical anaesthesia can attenuate this response.
