Background: An imbalance of vaso‐constrictor and ‐dilator mediators has been implicated in the pathogenesis of the pulmonary hypertension accompanying neonatal hypoxemic respiratory failure (NHRF).Aim: To characterize plasma PGE2, TXB2and their ratio in normal newborns and in those with NHRF.Methods: Twenty newborns with NHRF received inhaled PGE1(IPGE1) by jet nebulizer in doses of 25, 50, 150 and 300 ng/kg/min followed by weaning. Blood for PGE2and TXB2assay using EIA was available in 8 neonates with NHRF prior to IPGE1. Umbilical cord arterial samples were also obtained at delivery from 10 normal newborns to serve as controls.Results: Compared to normal newborns, those with NHRF had significantly lower PGE2/TXB2ratios after controlling for preterm gestation (<37 weeks) and postnatal age (p < 0.05). Notably, all subjects except one in the NHRF group had a value of <1.0 (range 0.1–1.2) compared to a value of > 1.0 in all subjects in the Control group (range 1.1–5.2).Conclusions: Lower PGE2/TXB2ratio in subjects with NHRF compared with controls reflects a predominance of vaso‐constrictor activity in these patients as the basis of pulmonary hypertension. Plasma PGE2/TXB2ratio may have important implications for the diagnosis and treatment of NHRF.
