The dual lumen internal jugular venous catheter has proven to be the most useful temporary vascular access for hemodialysis. According to this evidence it was decided to evaluate urea recirculation rate during hemodialysis performed by dual lumen internal jugular catheter (IJC) under normal condition (R1) and when the arterial lumen of the catheter is used as venous lumen, and the venous lumen as arterial lumen (R2).
In 71 patients who underwent hemodialysis using a dual lumen IJC, urea recirculation rate was measured during a conventional bicarbonate hemodialysis, under normal condition R1 and during the experimental condition R2.
Urea recirculation rate < 5% was achieved for almost all patients under normal condition R1. In the different condition R2, urea recirculation rate increased in all patients, from an average value of 3.7 +/- 1.7 to 5.1 +/- 1.8 p < 0.0001. This increment was expected ut surprisingly low.
In conclusion during hemodialysis with dual lumen IJC efficient treatment can be provided in normal condition and also when the venous lumen is used as arterial lumen.
