Abstract
Aim To evaluate if video based education could improve quality of positive pressure ventilation (PPV) performed by novice health care providers during neonatal resuscitation.
Methods Twenty-eight 4th year medical students were randomly paired and instructed to give PPV to a modified manikin as single-person resuscitators, then as two-person paired resuscitators using either an anatomical shaped neonatal face mask with an air cushion rim (IS) or a Laerdal round face mask (LM). After watching a video-tutorial they randomly repeated each mask ventilation performance. Airway pressure, gas flow, tidal volume, and mask leak were recorded. PPV performance quality was analysed using video recording.
Results Mask leak was lower during one-person ventilation when using IS (56 ± 16%) compared to LM (71 ± 19%). LM mask leak during one-person ventilation was significantly lower when using the two point top hold in contrast to the ok rim hold (before training: 63 ± 22% vs. 72 ± 18%, after training: 57 ± 17% vs. 77 ± 12%, respectively). Watching a video-tutorial improved correct head position (score: 1.4 ± 0.7 vs. 3.8 ± 0.4) and chin lift manoeuvre (score: 2.3 ± 0.2 vs. 3.5 ± 0.2) during PPV, however mask leak was not significantly reduced.
Conclusion A self-instructional educational video on adequate bag mask ventilation significantly improves performance quality scores in novice health care providers.
