Brief Summary

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.

Conditions

Respiratory Failure; Intubation

Outcome Measures

Primary Outcomes (1)

• Intubation Success Rate

  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 / \[the number of attempts\].

  less than 24 hours

Secondary Outcomes (4)

• Intubation Time

  less than 24 hours

• Glottic View Time

  less than 24 hours

• Cormack-Lehane Score

  less than 24 hours

• Airway Complications

  The participants' will be followed for the duration of hospital stay, an expected average of 2 days
