Different Types Of Laryngoscopes During Routine Intubation in Adult Patients

C-MAC videolaryngoscope (Karl Storz, Tuttlingen, GERMANY) with its Macintosh like blade is used with standard direct laryngoscopy technique. KingsVisionTM videolaryngoscopes (KingSystems, IN, USA) have also Macintosh like single use blades that are channeled, wider and shorter than conventional Macintosh blades.We aim to compare these two laryngoscopes and Macintosh laryngoscope during routine intubation in adult patients.

Treatment and study plan

Laryngoscopy

Device

Other names: C-MAC videolaryngoscopy (Karl Storz, Tuttlingen, GERMANY), KingsVision videolaryngoscopy (KingSystems, IN, USA), Macintosh Laryngscope (Welch Allyn,USA)

Primary outcomes

  1. Cormack-Lehane Score

    Time frame: 5 minutes

    Patients will be preoxygenated with 100% oxygen for 3 minutes before the anesthesia induction. After induction when the train of four ratio reaches %0, patients will be intubated by one of three anesthesiologists with at least 10 years of experience. The anesthesiologist first will use the Macintosh laryngoscope then KingsVisionTM videolaryngoscope and lastly C-MAC videolaryngoscope to intubate the patients. The Cormack-Lehane scores observed during each laryngoscopy will be recorded

Secondary outcomes

  1. time

    Time frame: 5 minutes

    Patients will be preoxygenated with 100% oxygen for 3 minutes before the anesthesia induction. After induction when the train of four ratio reaches %0, patients will be intubated by one of three anesthesiologists with at least 10 years of experience. The anesthesiologist first will use the Macintosh laryngoscope then KingsVisionTM videolaryngoscope and lastly C-MAC videolaryngoscope to intubate the patients. The time from the start of laryngoscopy to the visualization of the vocal cords and the time from the visualization of the vocals from the successful intubation observed during each laryngoscopy will be recorded.
