Epiglottic Downfolding During Endotracheal Intubation

NCT01691963 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

Summary

Usually videolaryngoscopy using a videolaryngoscope with a classic Macintosh design is performed with the blade in the vallecula and the epiglottis elevated from the vocal cords indirectly, as in direct laryngoscopy. However, during an audit of videolaryngoscopic practice we noticed that, in obtaining the best view, clinicians frequently and inadvertently advanced the blade into the vallecula to get a better view, such that the epiglottis was downfolded and elevated directly from the vocal cords. However, a better view does not necessarily lead to higher intubation success.

In this randomized, controlled trial, we want to determine the efficacy of videolaryngoscope-guided tracheal intubation using an alternative position for the blade in patients with normal airways.

Conditions

  • Intubation Complication
  • Injury of Epiglottis

Interventions

DEVICE

C-MAC® videolaryngoscope (Karl Storz, Tuttlingen, Germany)

Endotracheal intubation will be achieved using a C-MAC® videolaryngoscope (Karl Storz, Tuttlingen, Germany) with a size 3 Macintosh blade. The best possible view of the glottic inlet will be scored with the blade tip positioned in the vallecula. Next, the view of the glottic inlet will be scored with the blade advanced further into the vallecula, until the epiglottis flips infero-posteriorly and becomes downfolded into the trachea. The glottic view will be scored in both positions using the Cormack and Lehane classification system. After successful intubation, the blade will slowly be withdrawn into the vallecula to elevate the epiglottis back to its normal position.
