Abstract
Objective
In fetuses with severe congenital diaphragmatic hernia, fetal endoluminal tracheal
occlusion (FETO) with balloon increases survival and reduces morbidity. Balloon removal
is often scheduled electively. In urgent cases, in-utero removal is impossible and
removal immediately after delivery has to occur, posing risk of death from airway
obstruction. Medical staff need training in urgent removal. Ideal training method
is unclear; thus, we compared the performance of two groups trained by different methods.
Methods
24 medical students were randomly assigned to two different learning methods for removal:
Group 1 (in-person lecture) and Group 2 (online video). Both methods presented the
same information: endoscopic instrument set-up, anatomical landmarks for intubation,
and balloon removal. All participants were evaluated using the same instruments and
high-fidelity simulator, comparing time for instrument set-up and simulate balloon
removal (including removal attempts).
Results
Group 1 took significantly less time for instrument set-up compared to Group 2 [62
(30–92) secs vs 81 (57–108) secs; p < 0.01)]; no difference in time to intubate and
locate the balloon [75 (50–173) secs vs 92 (32–232) secs; p 0.42], or number of attempts.
Conclusion
There was no difference between video training and in-person training with regards
to the time taken to locate the FETO balloon in the trachea and to simulate its removal.
