Abstract

OBJECTIVE:

To compare ventilation properties and user preference of a new upright neonatal resuscitator developed for easier cleaning, reduced complexity, and possibly improved ventilation properties, with the standard Laerdal neonatal resuscitator.

DESIGN:

Eighty-seven Tanzanian and Norwegian nursing and medical students without prior knowledge of newborn resuscitation were briefly trained in bag-mask ventilation. The two resuscitators were used in random order on a manikin connected to a test lung with normal or low lung compliance. Data were collected with the Laerdal Newborn Resuscitation Monitor. The students graded mask seal and ease of air entry on a four-point scale ranging from 1 ('difficult') to 4 ('easy') and stated which device they preferred. (Equipment from Laerdal Global Health and Laerdal Medical).

RESULTS:

For upright versus standard resuscitator and normal lung compliance, mean expiratory lung volume was 15.5 mL vs 13.9 mL (p=0.001), mean mask leakage 48% vs 58% (p<0.001), and mean airway pressure 20 cm H2O vs 19 cm H2O (p=0.003), respectively. For low lung compliance, mean expiratory lung volume was 8.6 mL vs 8.1 mL (p=0.045), mean mask leakage 53% vs 62% (p<0.001), and mean airway pressure 21 cm H2O vs 20 cm H2O (p=0.004) for upright versus standard. The upright resuscitator was preferred by 82% and 68% of students during ventilation with normal and low lung compliance, respectively (p=0.001).

CONCLUSIONS:

Expiratory volumes were higher, mask leakage lower, and mean airway pressure slightly higher with upright versus standard resuscitator when ventilating a manikin. The majority of students preferred the upright resuscitator.
