Developmental changes in respiratory, febrile, and cardiovascular responses to PGE(2) in newborn lambs.


PGE(2) has centrally mediated respiratory, febrile, and cardiovascular effects that markedly differ between fetal and adult life. We hypothesized that the transition from fetal to adult responses to PGE(2) occurs in the newborn period. Thus effects of an intracarotid infusion of PGE(2) (3 microg/min for 60 min) were determined in unanesthetized newborn… (More)
