| Abstract: | The effects of pharmacological doses of glucagon (0.5 micrograms/kg/min) were studied in 8 chronically-catheterised fetal sheep. These doses of glucagon raised fetal blood glucose, and caused a small fall in fetal arterial PO2 (P less than 0.05). Arterial PCO2 rose (P less than 0.05) and pH fell (P less than 0.05) while plasma osmolality increased (P less than 0.01). There were no effects of glucagon on fetal renal function but in the fetus, like the adult, i.v. glucagon caused increases in heart rate (P less than 0.01) which were not associated with changes in arterial pressure. |
