Comparison Using a VLS Using GlideRite Stylet Versus TCI Articulating Introducer in Predictive Difficult Intubation

Официальное название

Comparison of Video Laryngoscope (VLS) With GlideRite Ridge Stylet vs Video Laryngoscope With the TCI Articulating Indroducer for Endotracheal Intubation in Predicted Difficult Airways. A Prospective Randomized Control Trial

Обзор

This study will assess the feasibility of using the TCI Articulating Device with video-laryngoscope in predictive, difficult airway, endotracheal intubation cases. It is meant to show the use of this device is equivalent to using the GlideRite Rigid Stylet with video-laryngoscope.

• Устройство video-laryngoscope and GlideRite Rigid Stylet
  Once subject is in the operating room, standard monitoring will be instituted including nerve stimulator. Induction will follow standard practice.Once full muscle relaxation is confirmed with a train of four of 0/4 laryngoscopy will be preformed using a video-laryngoscope (VLS) with a #3 blade for women and a #4 blade men. Endotracheal intubation will be performed using a #7 endotracheal tube in women and # 8 in men using the GlideRite Rigid Stylet. The stylet will be shaped to the curvature of

  In the operating room, standard monitoring will be instituted including nerve simulator. Induction will follow standard practice. Once full muscle relaxation is achieved (train of four of 0/4) laryngoscopy will be performed using a video-laryngoscope (VLS) using a #3 blade in women and a #4 blade in men. A #7 endotracheal tube will be used for women and a #8 for men. Endotracheal intubation will be performed by placing the tube on the back of the TCI articulating introducer, after shaft is lubri

Первичные конечные точки

• Time to successful intubation using a combination of video-laryngoscope and TCI Articulating Device will be equilivant to intubation success usinging a combination of video-laryngoscope and GlideRite Rigid Stylet [Срок оценки: time measured in seconds with an estimated time of 30 to 120 seconds from the start of intubation to endotracheal tube placement verified by CO2]

Вторичные конечные точки (4)

• Ease of intubation using TCI Articulating Device as compaired to GlideRite Rigid Stylet as rated by provider [Срок оценки: completed immediately after subject intubation]
• Need to use a maneuver called "corkscrew" ETT to pass glottis [Срок оценки: Period in seconds with an estimated time of 30 to 120 seconds between start of intubation procedure to ETT placement or failure to place]
• Blood in airway [Срок оценки: Period in seconds with an estimated time of 30 to 120 seconds between start of use of TCI Articulating Device to placement of ETT tube or failure to place]
• Time to intubate using either control or intervention [Срок оценки: Time measured in seconds, with an estimated time of 30 to 120 seconds, from time of first view of glottis to time ETT placement or failure to place]
