Insights
Video-assisted fiberoptic intubation (VAFI) and traditional fiberoptic intubation (FOI) showed no significant difference in success time for novice trainees in a pediatric simulation. Further research is needed to determine safer methods for pediatric airway management.
Area of Science:
- Pediatric Anesthesiology and Airway Management
- Medical Simulation and Training Technologies
Background:
- Children face higher risks of hypoxemia during tracheal intubation due to unique physiology.
- Fiberoptic intubation (FOI) is common for difficult pediatric airways but requires extensive training.
- Novice trainees performing FOI in children are at increased risk of adverse events.
Purpose of the Study:
- To compare the efficacy of video-assisted fiberoptic intubation (VAFI) against traditional FOI.
- To evaluate these techniques in novice medical professionals using a high-fidelity pediatric simulator.
- To identify a potentially safer intubation method for pediatric patients with difficult airways.
Main Methods:
- A randomized, controlled, simulation-based study involving 28 registered operating room nurses.
- Participants were assigned to either the FOI group (no aid) or the VAFI group (using a video laryngoscope).
- Primary outcome: time to complete tracheal intubation; secondary outcomes: vocal cord passage time, attempts, and success rate.
Main Results:
- No significant difference in median intubation time between FOI (55.0s) and VAFI (42.5s), P = 0.22.
- Secondary outcomes, including time to vocal cord passage, intubation attempts, and first success rate, were also not significantly different.
- The study did not find VAFI to be superior to conventional FOI in this simulated pediatric setting.
Conclusions:
- Video-assisted fiberoptic intubation (VAFI) did not demonstrate superiority over traditional fiberoptic intubation (FOI) for novice providers in a pediatric simulator.
- The study highlights the need for further investigation into improved techniques for pediatric airway management by inexperienced clinicians.
Introduction:
Life-threatening hypoxemia during tracheal intubation is more likely to occur in children than adults due to its unique physiological and anatomical nature. Fiberoptic intubation is widely performed in children with difficult airways. However, mastery of fiberoptic intubation requires substantial training, and novice trainees need to attempt fiberoptic intubation in children at high risk of respiratory-related adverse events. Therefore, a safer method than traditional fiberoptic intubation for children with difficult airways is desirable for novice anesthesia trainees. This study aimed to compare the efficacy of video-assisted fiberoptic intubation (VAFI) with that of traditional fiberoptic intubation (FOI) in a high-fidelity pediatric simulator by medical professionals with no experience in tracheal intubation.
Method:
This randomized, controlled, simulation-based study was conducted in a tertiary-care pediatric hospital. Registered nurses working in the operating room were enrolled in this study and randomly assigned to either the FOI or VAFI groups. Participants in the FOI group performed fiberoptic intubation without the aid of any device, whereas those in the VAFI group used a video laryngoscope to obtain a better glottic view. The primary outcome was the time from the moment the tip of the flexible bronchoscope passed between the upper and lower incisors until the completion of tracheal intubation.
Results:
A total of 28 participants were enrolled in this study. There was no significant difference in the time until the completion of tracheal intubation between FOI and VAFI, with a median time of 55.0 seconds for FOI and 42.5 seconds for VAFI (P = 0.22). Secondary outcomes, including time until passing the vocal cord, the number of intubation attempts, and the first success rate, did not also illustrate the significant difference between the groups.
Conclusion:
This study did not demonstrate the superiority of VAFI over conventional FOI in a high-fidelity pediatric simulator by medical providers with no experience in tracheal intubation.
