Randomised crossover study on pulse oximeter readings from different sensors in very preterm infants.

Objective: In extremely preterm infants, different target ranges for pulse oximeter saturation (SpO) may affect mortality and morbidity. Thus, the impact of technical changes potentially affecting measurements should be assessed. We studied SpO readings from different sensors for systematic deviations.

Catheter insertion depths in less-invasive surfactant administration.

Introduction: Less-invasive surfactant administration (LISA) under continuous positive airway pressure is increasingly used for the treatment of neonatal respiratory distress. Different procedures are described, but data on the optimal catheter insertion depth are sparse.

Objective: To generate data for recommending an optimal catheter insertion depth in LISA.

Clinical evaluation of an application aid for less-invasive surfactant administration (LISA).

Background: Less-invasive surfactant administration (LISA) is increasingly used. We investigated the feasibility of a new LISA-device (Neofact®) in neonates.

Design: Prospective observational pilot study with open-label LISA in two tertiary neonatal intensive care units.

Nasal insertion depths for neonatal intubation.

Aim: Data on the depth of nasal intubation in neonates are rare, although this is the preferred route in some countries. Therefore, recommendations on optimal nasal intubation depths based on gestational age (GA) and weight are desirable.

Methods: We determined the distances between the middle of thoracic vertebrae 2 (T2) and the tip of the endotracheal tube in 116 X-rays from nasally intubated neonates.
