Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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 with Clarus and endo-tracheal tube will be passed into trachea. This procedure will take 5 minutes.
