Background
Neonates with persistent pulmonary hypertension of the newborn (PPHN) can present with hypoxia and right ventricular dysfunction with resultant inadequate oxygen delivery and end‐organ damage. This study describes the use of prostaglandin‐E1 (PGE) for ductal patency to preserve right ventricular systolic function and limit afterload in newborns with PPHN.
Methods
This is a retrospective...
Introduction
Pulmonary artery acceleration time (PAAT) is considered useful for the non‐invasive evaluation of pulmonary artery pressure (PAP) and pulmonary vascular resistance (PVR). PAAT is dependent on PAP, PVR, pulmonary artery compliance, stroke volume, and heart rate. Its relative dependency on these determinants may differ between young and older children, raising uncertainty regarding its...
