Different Types Of Laryngoscopes During Routine Intubation in Adult Patients

April 1, 2013 updated by: Guniz M.Koksal, Istanbul University

Comparison Of C-MAC Videolaryngoscopy, Kingsvision Videolaryngoscopy and Macintosh Laryngoscopy 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.

  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Laryngoscopy
Patients will be intubated by an experienced anesthesiologists. Anesthesiologist first uses Macintosh laryngoscope then KingsVision videolaryngoscope and lastly C-MAC videolaryngoscope to intubate patients. Cormack-Lehane scores, the time from the start of laryngoscopy to visualization of the vocal cords and the time from the visualization of the vocals from the successful intubation will be recorded. The success of the intubation will be assessed with bilateral chest auscultation. If visualization of the vocal cords or placing of the endotracheal tube was not successful after 60 seconds with a particular laryngoscope, it will be left out and patient will be ventilated for 1 minutes and then pass to other laryngoscopes.
Device: laryngoscopy
Other Names:
  • C-MAC videolaryngoscopy (Karl Storz, Tuttlingen, GERMANY)
  • KingsVision videolaryngoscopy (KingSystems, IN, USA)
  • Macintosh Laryngscope (Welch Allyn,USA)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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
5 minutes
