Editing Peritoneal dialysis catheter


Tenckhoff catheter

== Principles ==

* Relies on solute flow across the peritoneum to allow for dialysis of waste products
* Different areas of peritoneum contribute differently
* Loss of significant visceral peritoneum (large small bowel resection or colectomy) may only reduce filtration by 10-20%

== Technique ==

* LUQ cut-down/optical entry
* Additional 5mm port for manipulation
* Entry site 3cm lateral to umbilicus
* Insert pull-apart sheath and then catheter, angling down towards pelvis. Try to tunnel it within the abdominal wall, so the defects in anterior and posterior fascia are not superimposed.
* Pull the sheath apart, keeping the catheter in place
* Tunnel the external part of tubing to LUQ
* Close up
