Population

Cats (small intestine model) undergoing hemorrhagic hypotension

Comparison

Intermittent stimulation of regional sympathetic… vs Baseline/control periods

Design

Preclinical

Follow-up

2-2.5 hours

Implication

May limit compensatory vasoconstriction in prolonged shock; hypothesis-generating and requires human validation.

Structured PICO

P
Population
Cats (small intestine model) undergoing hemorrhagic hypotension
I
Intervention
Intermittent stimulation of regional sympathetic vasoconstrictor fibres at 4 Hz
C
Comparator
Baseline/control periods (before and after hypotension)
O
Outcome
Nervous responsiveness of resistance and capacitance vessels, capillary filtration coefficient (CFC), and tissue volumesurrogate

During hemorrhagic hypotension, sympathetic vasoconstrictor responsiveness in the small intestine declines, which is exacerbated by lower perfusion pressure and acidosis.
