An interventional study of Railroaded bougie and Preloaded bougie in Endotracheal Intubation, Cardiopulmonary Resuscitation and Simulation, sponsored by Peking Union Medical College Hospital. Completed at 1 site in China. Per ClinicalTrials.gov, last updated 2023-06-13.
Sponsored by Peking Union Medical College Hospital · Not applicable, Interventional, and Treatment
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.
Peking Union Medical College Hospital is the lead sponsor of 1,115 studies on the registry; 463 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
An endotracheal tube is loaded onto a bougie posterior to the placement of the bougie into the trachea.
Device: Railroaded bougie
An endotracheal tube is loaded onto a bougie prior to initiating laryngoscopy.
Device: Preloaded bougie
A stylet is placed within an endotracheal tube prior to initiating laryngoscopy.
Device: Stylet
Residents expose the glottis by a video laryngoscope and perform the endotracheal intubation without assistance of stylet or bougie.
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.
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.
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.
Failure on the first attempt
An attempt is terminated and defined as a failure when a resident tries for one minute but is still unable to start ventilation, or when a resident feels unable to succeed and decides to give up, or when a resident withdraws a laryngoscope blade, a bougie, or a tube out of the month after the initial insertion. This outcome will be measured based on videos of endotracheal intubation procedures recorded by a camera placed on the right side of the manikin.
Time frame: At the completion of the intubation
Failure on two attempts
If the first attempt of a method fails, the resident will be given a second opportunity of the same method. This outcome will be measured based on videos of endotracheal intubation procedures recorded by a camera placed on the right side of the manikin.
Time frame: At the completion of the intubation
Duration of the first attempt
The time elapsed between the insertion of a laryngoscope blade into the month and either the start of ventilation in a successful attempt or the termination of a failed attempt. This outcome will be measured based on videos of endotracheal intubation procedures recorded by a camera placed on the right side of the manikin.
Time frame: At the completion of the intubation
Overall intubation duration
Duration of the first attempt if it succeeds or the sum of the duration of both attempts if the first attempt fails. This outcome will be measured based on videos of endotracheal intubation procedures recorded by a camera placed on the right side of the manikin.
Time frame: At the completion of the intubation
Self-reported intubation difficulty
0-10 ranking scale with 0 representing "the easiest" and 10 "the most difficult" rated by the residents.
Time frame: At the completion of the intubation
