Intubation quality and hemodynamic response in endotracheal intubation with ultrasound-guided bilateral superior laryngeal nerve block: Case series

Abstract

General anesthesia works centrally, causing loss of consciousness and blocking the pain response. Some of the general anesthesia techniques are using laryngoscopy and intubation. The side effects of endotracheal intubation, for instance, are stimulating cough reflex, laryngospasm, and sympathetic nervous system response that increases catecholamine levels. The side effects are increases in blood pressure and heart rate. Hereby, a big consent for anesthesiologists thus intravenous, topical, and regional drugs are usually needed to facilitate this action. Using a muscle relaxant to facilitate intubation is often performed but does not suppress the hemodynamic responses. Intubation with superior laryngeal nerve block technique has an equivalent quality compare with muscle relaxant uses. This technique can prevent hemodynamic responses from laryngoscopy endotracheal intubation.
