Select the Catheter
Anorectal manometry investigations can be performed by either using (a)
water catheters with DT-NN pressure transducers, (b) air-charged catheters
with external pressure transducers or (c) solid state catheters. LABORIE
advises to use catheters with 4 pressure channels for the most accurate
results.
The layout of the two most common 4-channel catheters is displayed in
Figures 9.2 and 9.3:
•
one cm spacing between the four pressure channels (spiral) and a balloon
at the tip in order to test the anorectal reflex (RAIR) and sensations.
•
four pressure channels at the same location (radial) with an angle of 90
degrees and a balloon at the tip in order to test the anorectal reflex (RAIR)
and sensations.
