Repeated lumbar or ventricular punctures vs conservative treatment

Infection of CSF presurgery · preterm infants less than three months of age with either: a) IVH demonstrated by ultrasound or computed tomography (CT) scan; or b)…

Repeated lumbar or ventricular punctures showed no clear difference in infection of CSF presurgery compared with conservative treatment (low certainty).

HFNC vs continuous positive airway pressure (CPAP)

Death (before hospital discharge) or BPD (supplemental oxygen/respiratory support at 36 weeks' postmenstrual age if born < 32 weeks' gestation, or 28 days if born ≥ 32 weeks' gestation) · preterm infants requiring primary respiratory support

Nasal high flow showed no clear difference in death (before hospital discharge) or BPD(supplemental… compared with continuous positive airway pressure (low certainty).

HFNC vs nasal intermittent positive pressure ventilation

Nasal trauma (during assigned treatment) · preterm infants requiring primary respiratory support

Nasal high flow probably leads to lower nasal trauma (during assigned treatment) compared with nasal intermittent positive pressure ventilation (moderate certainty).
