简要总结
The investigators studied the efficiency of Macintosh laryngoscope and the King Vision video laryngoscope in adult patients scheduled for general anesthesia. Best Cormack-Lehane score obtained, glottic view time, intubation time, time to ventilation, correlation between the Mallampati classification and the Cormack-Lehane grades, and complications related to laryngoscopy and intubation has been investigated.
详细描述
Securing the airway is essential in general anesthesia. Anesthetic problems related to airway management constitute 17% of closed claims, difficult intubation being the most common one with an occurrence rate of 5%. Problems like delayed intubation, misplaced tracheal tube, or airway trauma are frequently seen in outpatient settings and end up with either death or hypoxic brain damage. Therefore, preoperative visit should include detailed assessment of the airways according to clues of difficult intubation.Several studies compared the King Vision video laryngoscope with other laryngoscopes in manikins simulating difficult airway scenarios, and reported better glottic views. The investigators aimed to study the correlation between the Mallampati classification and the glottic views (Cormack-Lehane grade) obtained with Macintosh laryngoscopy, and the King Vision video laryngoscopy in adult patients scheduled for general anesthesia. Secondary outcomes will be successful intubation rate, time to obtain the best view, time to successful intubation, and complications related to laryngoscopy will be compared.

结局指标
主要结局
Intubation Success Rate
时间窗: less than 24 hours
Endotracheal intubation attempt is defined as entrance of the endotracheal tube into the patient's mouth. Any major change in the alignment of the laryngoscope is defined as another intubation attempt. Successful endotracheal intubation is defined as the endotracheal cuff passing through the patient's vocal cords. Intubation success rate is defined as: 1 / \[the number of attempts\].
次要结局
- Cormack-Lehane Score(less than 24 hours)
- Intubation Time(less than 24 hours)
- Glottic View Time(less than 24 hours)
- Airway Complications(The participants' will be followed for the duration of hospital stay, an expected average of 2 days)
