Key result
Bilateral carotid occlusion increased net intestinal fluid absorption by 30-40% in rats and cats, an effect that was eliminated by sympathetic denervation.
Why the study?
Does bilateral carotid occlusion affect net fluid absorption in the small intestine of rats and cats?
Does bilateral carotid occlusion affect net fluid absorption in the small intestine of rats and cats?
Effect estimate: 30-40% increase
Arterial baroreceptors influence net fluid transport in the small intestine via sympathetic pathways, serving as a reflex compensatory mechanism during hypotension.

Baroreflex sympathetic activation may augment intestinal fluid absorption during hypotension in animals; leaves open translation to human physiology or therapy.
Sjövall et al. (1982) studied this question. Bilateral carotid occlusion vs. Baseline / denervation procedures was evaluated on Net intestinal fluid absorption (30-40% increase). Bilateral carotid occlusion increased net intestinal fluid absorption by 30-40% in rats and cats, an effect that was eliminated by sympathetic denervation.
