Renal hemodynamic responses to hypoxemia during development: relationships to circulating vasoactive substances.

Abstract:

:Chronically catheterized fetal lambs (n = 11, gestational age 111-139 days) and neonatal lambs (n = 20, postnatal age 4-30 days) were studied to explore during development the relationship of renal hemodynamic responses during hypoxemia to plasma epinephrine concentration (E), plasma norepinephrine concentration (NE), plasma arginine vasopressin concentration (AVP), and plasma renin activity (PRA). A low oxygen gas mixture (11.1 +/- 0.1% O2) was administered for 30 min to the pregnant ewe or neonatal lamb to induce hypoxemia with maintenance of normal arterial pCO2 and pH. Arterial blood pressure was recorded continuously and renal blood flow (RBF) was determined by the radiolabeled microsphere technique. Moderate hypoxemia (pO2 16 +/- 2 torr and 33 +/- 6 torr in fetus and neonate, respectively) induced increases in E, NE (measured by radioenzymatic assay), and AVP (measured by radioimmunoassay) in both fetus and neonate. PRA (measured by radioimmunoassay) also increased in response to hypoxemia in neonatal lambs. The change in mean arterial pressure with hypoxemia (delta MAP) was significant in fetuses (delta MAP 8 +/- 14%, p less than 0.05) but not in lambs (delta MAP 1 +/- 10%, p greater than 0.5). Similarly, the change in renal blood flow with hypoxemia (delta RBF) was significant (delta RBF -51 +/- 24%, p less than 0.001) in fetuses but not in neonatal lambs (delta RBF -9 +/- 38%, p greater than 0.1). These results reflected a change in renal vascular resistance with hypoxemia (delta RVR) that was significant in fetal lambs (delta RVR 169 +/- 168%, p less than 0.01) but not in neonatal lambs (delta RVR 51 +/- 180%, p greater than 0.2).(ABSTRACT TRUNCATED AT 250 WORDS)
