Mask ventilation with two different face masks in the delivery room for preterm infants: a randomized controlled trial

Abstract

The use of either face mask during PPV in the delivery room yields similar mask leak in preterm infants <33 weeks gestational age.

Using exhaled CO2to guide initial respiratory support at birth: a randomised controlled trial

“…During PPV and SI, the default settings were gas flow of 8 L/min, PIP of 24 cmH 2 O and PEEP of 6 cmH 2 O. Staff members attending deliveries were trained to use the device and were familiar with both face masks 23. During PPV, respiratory rate was aimed at 40–60/min.…”

A new suction mask to reduce leak during neonatal resuscitation: a manikin study

“…In contrast to other masks previously tested in manikin models8 9 or infants4 this is the first mask showing a reduction in leak compared with the conventional mask. This might be due to the sealing effect of the negative pressure between the inner and outer rims of the suction mask.…”

“…However, delivering effective mask ventilation can be challenging, because of large leak around the mask. Studies report variable leak, sometimes >50% of inspiratory volume, during mask PPV in preterm infants in the DR 3 4…”

Exhaled Carbon Dioxide and Neonatal Breathing Patterns in Preterm Infants after Birth

“…Although the decision of face masks used could have introduced bias, the research team had no influence in this decision. Nonetheless, a recent study by Cheung et al, 19 compared Fisher and Paykel and Laerdal round face masks and reported no difference in mask leak between the 2 masks. Therefore, we believe this bias would be negligible in the current study.…”

“…11 This is further supported by ECO 2 measurements in 20 term infants over the first 120 seconds after birth. 13 Overall, it took a median (range) of 3 (1-8) breaths or 15 (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22) seconds after birth until ECO 2 was first detected. Once ECO 2 was detected, it increased significantly, and this was also associated with increases in V T , suggesting facilitation of FRC and lung aeration.…”
