简要总结
This study evaluated two different devices used for placing a breathing tube (endotracheal intubation) in adult patients undergoing elective surgery. The aim was to compare the King Vision videolaryngoscope, which has a camera and a guiding channel for the tube, with the traditional Macintosh laryngoscope, which allows doctors to look directly at the vocal cords. The study focused on how long it takes to successfully insert the tube, the need for additional maneuvers during the procedure, and the overall success rate of first attempts. The procedures were performed by novice operators under supervision.

结局指标
主要结局
Time to successful endotracheal intubation (seconds)
时间窗: During intubation (intraoperative period, approximately 1-2 minutes)
Measured from insertion of the laryngoscope blade between the patient's incisors until removal of the blade after correct placement of the endotracheal tube, confirmed by capnography.
