Abstract

Pregnant animals are less able to maintain arterial blood pressure (BP) during hemorrhage (H). Because BP is initially maintained by reflex vasoconstriction, this study tested the hypothesis that reflex decreases in vascular conductance (CON) are attenuated during pregnancy. Rabbits were instrumented with arterial and venous catheters and flow probes around the distal aorta (HQ; n=7), renal artery (REN; n=5) and/or mesenteric artery (MES; n=3). Rabbits were bled via the venous catheter at 2% of the initial blood volume (BV) per min before (NP) and at the end of pregnancy (P). Before H, BP was lower in P rabbits (67±3 vs. 59±2 mmHg; p
