Nasal continuous positive airway pressure (NCPAP) devices using variable (vf-) and continuous (cf-) flow or synchronized nasal intermittent positive pressure ventilation (s-NIPPV) are used to prevent or treat intermittent hypoxia (IH) in preterm infants. Results concerning which is most effective vary. We aimed to investigate the effect of s-NIPPV and vf-NCPAP compared to cf-NCPAP on the rate of IH episodes. Preterm infants with a gestational age of 24.9–29.7 weeks presenting with IH while being treated with cf-NCPAP were monitored for eight hours, then randomized to eight hours of treatment with vf-NCPAP or s-NIPPV. Data from 16 infants were analyzed. Due to an unexpectedly low sample size…
Survey of neonatal respiratory support use in very preterm infants in Italy
2012
Background: Respiratory support in very preterm infants is often a life-saving procedure and several techniques are available. There is lack of data on the current use of these techniques. Methods and aim: We analyzed a cohort of infants <30 weeks gestation or < 1501 g birth weight, enrolled in the Italian Neonatal Network in 2009 and 2010 (n = 8297, mean gestation = 29.3 weeks, mean birth weight = 1089 g) to ascertain the use of several techniques. We also conducted a questionnaire survey of all neonatal units adhering to the Italian Neonatal Network, inquiring about preferred methods of respiratory support. Results: Conventional ventilation was used in 53% of these infants, high frequency…
Development of a self-pumping extracorporeal blood oxygenation device characterized by a rotating shaft with embedded fiber packages.
2019
Introduction: To offer respiratory support for patients with lung disease, a novel technological solution for blood pumping and oxygenation is being developed. The pump–lung system was designed to integrate fiber membranes into six packages radially embedded in a rotating hollow shaft placed along the longitudinal axis of the device. Fiber packages are inclined with respect to the rotation axis so that the rotational motion of the rotating shaft allows a self-pumping system to be obtained. Method: Both hemodynamic and gas transfer performances were investigated using both in vitro experiments and in silico flow analyses. Results: The predicted flow velocity in the pump chamber was smooth an…
