Anatomical versus round facemasks for breathing support in newborns

NeoSHARK: Neonatal Study of Two-Handed Anatomical Versus Round facemasK Ventilation in Preterm and Term Infants; a Randomised Controlled Trial

Not applicable Interventional University College Dublin · NCT07524517

We will test whether an anatomical (triangular) facemask or a round facemask, both held with a two-handed grip, reduces air leak when giving breaths to preterm and term newborns who need mask ventilation before intubation.

What this trial studies

Facemask leak and airway obstruction are common during neonatal mask ventilation and can result in ineffective support for babies. This single-center interventional study will compare measured mask leak when healthcare professionals use either an anatomical facemask or a round facemask, both applied with a two-handed hold, during mask ventilation before intubation. The primary outcome is the amount of air leak recorded during ventilation. The goal is to determine whether one mask shape combined with a two-handed technique gives more effective mask seal in clinical neonatal care.

Who should consider this trial

Good fit: Preterm and term neonates in the neonatal unit who require mask ventilation prior to an attempted intubation and for whom the clinical team plans mask ventilation are eligible.

Not a fit: Infants with congenital facial malformations that affect mask seal, or babies who do not require mask ventilation prior to intubation, are unlikely to benefit from this comparison.

Why it matters

Potential benefit: If successful, the findings could reduce mask leak during neonatal ventilation and improve the effectiveness and safety of immediate breathing support for newborns.

How similar studies have performed: Previous manikin studies showed no consistent difference between mask shapes with a one-handed hold, while recent benchtop and some clinical data suggest a two-handed hold reduces leak for round masks, but the combination of an anatomical mask with a two-handed hold has not yet been tested clinically.
