简要总结
1. Title of the project:COMPARISION OF KING VISION VIDEO LARYNGOSCOPE WITH MACINTOSH LARYNGOSCOPE FOR NASOTRACHEAL INTUBATION: A RANDOMIZED CONTROL STUDY.
Securing the patients airway is essential in general anaesthesia. Airway management problems constitutes about 17 % of anaesthesia closed claims, with difficult intubation being the most common at a rate of 5%. Problems like delayed intubation, misplaced tracheal tube or airway trauma are frequently encountered in outpatient setting and can cause death or brain damage.
Video laryngoscopes have been proven useful for intubating patients with difficult airway. With camera and light source on the tip of its blade, the king vision video laryngoscope (KVVL) provides indirect glottis view without needing the align the oral-pharyngeal-tracheal axis.
Naso-tracheal intubation is commonly practiced in patients undergoing oro-maxillofacial surgery to provide a secure airway undergoing and good operation field.
This allows less tissue damage during laryngoscopy, leading to KVVL’s successful use in awake intubations.
Several studies have reported that KVVL provide better glottis views in comparison with other laryngoscopes when used by novice personnel.
It remains unclear however whether these results can translate into higher intubation success rates or shorter time to intubation when KVVL is used by experienced anaesthesiologists, hence we conduct this study to compare KVVL and Macintosh laryngoscope for nasotracheal intubation.

结局指标
主要结局
To compare the total intubation time and each time interval as follows,
时间窗: total time for intubation and each time intervals will be measured during the intubation.
time A- placement of the nasotracheal tube from selected nostril to oropharynx;
时间窗: total time for intubation and each time intervals will be measured during the intubation.
time C- nasotracheal tube advanced from oropharynx into trachea and removal of the scope form oral cavity.
时间窗: total time for intubation and each time intervals will be measured during the intubation.
time B- use of devices to view the glottic opening;
时间窗: total time for intubation and each time intervals will be measured during the intubation.
次要结局
