9.3.3 Solid-State Catheters
You can use reusable solid-state catheters with filling lumen and a balloon
fixation point at the tip.
You can use standard balloons or make a balloon catheter as follows. Use a
latex condom as a balloon. Cut the top 8 cm (approximately 3.25 inches) off
the condom. Use a piece of stitch wire to tie the condom to the catheter. Tie it
in such way that the rectal transducer is inside the balloon, while the anal
transducer is outside the balloon. Be careful not to apply excessive force to the
transducers or catheter. Do not bend the catheter.
The procedure to prepare the investigation is as follows:
▪
Pre-wet the catheter in water as described in manual of the manufacturer.
▪
Enter and select the patient name in the database program.
▪
Click the New investigation button in the database program.
▪
Click the Anorectal manometry button to start the pre-test.
▪
Connect the pre-wetted catheter to the CIM module.
▪
Press the Zero all button to zero all pressures to atmospheric pressure.
▪
Insert the catheter gently in the anal canal of the patient and position the
balloon in the rectum.
▪
Ask the patient to cough to check the registration of all pressures.
▪
Press the Start investigation button to start the investigation. Follow the
procedure for the tests as described in the next paragraphs.
9.3.4 Positioning of the Catheter
The position of the catheter in the anal sphincter depends on the layout of the
catheter:
•
If you are using the 4-channel spiral catheter with one cm spacing, then the
sensors should be positioned in the anal canal and the balloon in the
rectum. It is important to not move the catheter during the investigation and
performance of all anorectal tests.
•
If you are using the 4-channel catheter with radial sensors, you can position
the radial sensors at the high-pressure zone and perform all tests including
the profiles. Alternatively, you can position the radial sensors at the
proximal level (e.g., 4 cm inside the anal canal) and perform all tests, then
