Mask ventilation with two different face masks in the delivery room for preterm infants : a randomized controlled trial . BACKGROUND If an infant fails to initiate spontaneous breathing after birth , international guidelines recommend a positive pressure ventilation ( PPV ) . However , PPV by face mask is frequently inadequate because of leak between the face and mask . Despite a variety of available face masks , none have been prospectively compared in a randomized fashion . We aimed to evaluate and compare leak between two commercially available round face masks ( Fisher & Paykel ( F & P ) and Laerdal ) in preterm infants < 33 weeks gestational age in the delivery room . METHODS Infants born at the Royal Alexandra Hospital from April to September 2013 at < 33 weeks gestational age who received mask PPV in the delivery room routinely had a flow sensor placed between the mask and T-piece resuscitator . Infants were randomly assigned to receive PPV with either a F & P or Laerdal face mask . All resuscitators were trained in the use of both face masks . We compared mask leak , airway pressures , tidal volume and ventilation rate between the two groups . RESULTS Fifty-six preterm infants ( n=28 in each group ) were enrolled ; mean±s.d . gestational age 28±3 weeks ; birth weight 1210±448 g ; and 30 ( 52 % ) were male . Apgar scores at 1 and 5 min were 5±3 and 7±2 , respectively . Infants randomized to the F & P face mask and Laerdal face mask had similar mask leak ( 30 ( 25-38 ) versus 35 ( 24-46 ) % , median ( interquartile range ) , respectively , P=0.40 ) and tidal volume ( 7.1 ( 4.9-8.9 ) versus 6.6 ( 5.2-8.9 ) ml kg ( -1 ) , P=0.69 ) during PPV . There were no significant differences in ventilation rate , inflation time or airway pressures between groups . CONCLUSION The use of either face mask during PPV in the delivery room yields similar mask leak in preterm infants < 33 weeks gestational age .
