Abstract
Summary: Critically ill, full-term, and premature infants are at increased risk to develop gastric mucosal ulceration. The cytoprotective effects of prostaglandin E2 (PGE2) may be important in the preservation of gastric mucosal integrity in these patients. PGE2 concentrations in the gastric secretions of seven full-term and 16 premature infants with severe pulmonary disease were measured by radioimmunoassay. The mean PGE2 concentration was significantly greater in the full-term infants (460 ± 94 pg/ml), (mean ± S.E.M.) than in the premature infants (190 ± 35 pg/ml), P < 0.01. There was a linear correlation between gestational age and PGE2 concentration, r = 0.70, P < 0.001. In the 11 infants ≥35 wk gestational age there was a linear correlation between gastric pH and PGE2 concentration, r = 0.69, P < 0.01.
