Randomized Controlled Trial
Mask ventilation with two different face masks in the delivery room for preterm infants: a randomized controlled trial.
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. ⋯ The use of either face mask during PPV in the delivery room yields similar mask leak in preterm infants <33 weeks gestational age.

Comparative Study
Influence of patent ductus arteriosus and ventilators on electrical velocimetry for measuring cardiac output in very-low/low birth weight infants.
We evaluated electrical velocimetry, a noninvasive method for continuous cardiac output measurement, in very-low and low birth weight infants and the influence of patent ductus arteriosus (PDA) and ventilators on this method. ⋯ Although influenced by PDA, electrical velocimetry was generally interchangeable with transthoracic echocardiography even using ventilators.

Clinical Trial Observational Study
The concordance of ultrasound technique versus X-ray to confirm endotracheal tube position in neonates.
Given the distressingly high incidence of ETT malposition in the neonatal population, patients are exposed to ionizing radiation to confirm endotracheal tube (ETT) position. Our objective is to determine if ultrasound technique is concordant with X-ray in determining whether an ETT is deeply positioned or not. ⋯ As the largest clinical trial of its kind to date, with the greatest number of ultrasound operators, we have further established US as a feasible imaging modality to determine whether an ETT is deeply positioned or not.

During therapeutic whole body cooling (WBC), the core temperature is usually monitored with an esophageal probe. Most infants receive mechanical ventilation while being cooled. As the temperature in the esophagus responds rapidly to changes in the ambient temperature, inhalation of warmed gas from ventilator may lead to overestimation of ventilated patients' actual temperature, causing automated cooling devices to overcool patients well below the desired set temperature targets. To determine if the esophageal temperature recordings during therapeutic WBC differ between ventilated and non-ventilated infants. ⋯ Warmed inhaled gas does not interfere with the esophageal temperature during WBC.
