Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trials is to analyze the effects of using bougies as adjuncts on the performance of endotracheal intubation via video laryngoscopy during cardiopulmonary resuscitation in anesthesia residents. The main question it aims to answer is whether bougie use has a significant effect on first-attempt failure of endotracheal intubation via video laryngoscopy during continuous chest compressions. Participants will perform endotracheal intubation via video laryngoscopy by four methods in a randomized order in a simulated cardiopulmonary resuscitation scenario on a manikin. The four methods are endotracheal intubations assisted by a railroaded bougie, assisted by a preloaded bougie, assisted by a stylet, and with no assistance. Researchers will compare the first-attempt failure rate of the four methods to see if a railroaded bougie method has a significant different first-attempt failure from that of the other three methods.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Railroaded bougie

An endotracheal tube is loaded onto a bougie posterior to the placement of the bougie into the trachea.

Group Type EXPERIMENTAL

Railroaded bougie

Intervention Type DEVICE

Residents expose the glottis by a video laryngoscope and place the tip of bougie through the vocal cords. Then, an assistant loads an endotracheal tube on the free end of the bougie. Residents advance the endotracheal tube over the bougie and withdraw the bougie.

Preloaded bougie

An endotracheal tube is loaded onto a bougie prior to initiating laryngoscopy.

Group Type OTHER

Preloaded bougie

Intervention Type DEVICE

Residents expose the glottis by a video laryngoscope and perform the endotracheal intubation using a bougie with a preloaded endotracheal tube while an assistant secures the free end of the bougie. Residents withdraw the bougie when the endotracheal tube reaches an appropriate depth.

Stylet

A stylet is placed within an endotracheal tube prior to initiating laryngoscopy.

Group Type ACTIVE_COMPARATOR

Stylet

Intervention Type DEVICE

Residents expose the glottis by a video laryngoscope and perform the endotracheal intubation with the assistance of a stylet. An assistant withdraws the stylet when the tip of the endotracheal tube passes through the vocal cords. Then residents place the endotracheal tube to an appropriate depth.

Naked endotracheal tube

Residents expose the glottis by a video laryngoscope and perform the endotracheal intubation without assistance of stylet or bougie.

Group Type NO_INTERVENTION

No interventions assigned to this group

Intervention Type DEVICE
