[Hemodialysis with Bi-Flo cannulas]

D Falkenhagen, J Schulz, M Holtz

Zeitschrift Fur Urologie Und Nephrologie

|May 1, 1980

Summary

The Bi-Flo-puncture cannula is effective for chronic hemodialysis patients with adequate atrioventricular fistula flow. Before permanent use, check for shunt volume in the cannula, especially with moderate fistula function.

Area of Science:

Nephrology
Vascular Access
Medical Devices

Background:

Chronic hemodialysis requires reliable vascular access.
Atrioventricular fistulas are common access points.
Double-lumen cannulas aim to improve dialysis efficiency.

Purpose of the Study:

To evaluate the efficacy of the double-lumen Bi-Flo-puncture cannula in chronic hemodialysis.
To assess the impact of the cannula on dialysis effectiveness with atrioventricular fistulas.

Main Methods:

Utilized the double-lumen Bi-Flo-puncture cannula in chronic hemodialysis patients.
Monitored dialysis effectiveness in conjunction with atrioventricular fistula flow.
Investigated potential shunt volume within the cannula.

Main Results:

Adequate atrioventricular fistula flow ensured no significant decrease in dialysis effectiveness.
Potential shunt volume between cannula lumina was identified as a factor.

Conclusions:

The Bi-Flo-puncture cannula can be safely used in chronic hemodialysis with sufficient fistula flow.
Pre-use assessment for shunt volume is recommended for cannulas, particularly with moderate atrioventricular fistula function.
