Brief summary

A new, optical video stylet, Clarus Video system, was evaluated for tracheal intubation in paralyzed and non-paralyzed patients with normal airway.

Interventions

Anaesthesia will be induced with target-controlled infusion of propofol 5 µg / ml and remifentanil 4 ng / ml, 2 min later, succinylcholine 1.5 mg / kg or comparable volume of saline will be injected according to the group of succinylcholine or saline. Participants in the succinylcholine group will receive one succinylcholine injection only. In both groups, after visual confirm of the vocal cord, saline or succinylcholine will be injected intravenously, while patient’s airway being suspended wit

Participants in the succinylcholine group will receive one succinylcholine injection only. In both groups, after visual confirm of the vocal cord, saline or succinylcholine will be injected intravenously, while patient’s airway being suspended with Clarus and endo-tracheal tube will be passed into trachea. This procedure will take 5 minutes.
