Implication

Suggests extravascular oxygen shunting at resting flow in feline intestine; leaves open relevance to human gut perfusion.

Structured PICO

Population

Cats (small intestine model)

Intervention

Intra-arterial injection of red cells labelled with methemoglobin and oxygen under resting, vasodilatation (isopropylnoradrenaline), and vasoconstriction (sympathetic stimulation) conditions

Comparator

Comparison between resting state and vasodilatation/vasoconstriction states

Outcome

Venous appearance time of red cells versus oxygensurrogate

Demonstrates extravascular shunting of oxygen in the intestinal villi of cats at rest, which is abolished during vasodilation or vasoconstriction.
