Overview

No change to catheterization practice warranted; hypothesis-generating for stretch receptor reflexes in peripheral vessels.

Structured PICO

Does rapid distension of large arteries and veins affect the vascular tone of the fingers in patients undergoing diagnostic catheterization?

P
Population
Patients catheterized for diagnostic purposes
I
Intervention
Rapid flushing with saline or movements of the catheter against the vascular wall (rapid distension of large arteries and veins)
O
Outcome
Volume increase of the finger (vascular tone) measured by finger plethysmogramssurrogate

Rapid distension of large central arteries and veins during catheterization induces a reflex volume increase in the fingers, likely mediated by stretch receptors.
