NCT04772209

Brief Summary

In our study, investigators will investigate the effectiveness and complications of two catheter lock solutions one of which is the standard heparin routinely used in comparison to Sodium bicarbonate. Both solutions were used but not compared head to head. Investigators aim to compare both solutions in terms of catheter lumen patency and their effect on catheter-related infections.

Outcome Measures

Primary Outcomes (6)

  • Time to first catheter failure (day)

    The time from first sucessful dialysis session to the last one (in days)

    6 months

  • Total Duration of catheter usage (day)

    some patients need only 1-2 dialysis sessions while others may need too many sessions. In some cases a total of three dialysi sessions is whithin 3-4 days while others may need that number in wider range (e.g 10-14 days). Here both number and duraion effect is evaluated

    6 months

  • Number of participants with catheter occlusion

    The number of cases early catheter

    6 months

  • Number of patients with catheter related infection

    any catheter related infection(exit site, lumen inection etc) will be recorded

    6 months

  • Time of catheter occlusion or failure

    catheteres occluded by thrombi will be documented

    6 months

  • Causes of premature catheter malfunction

    any catheter needing exchange prematurly will be be evaluated for mulfunction cause (etiher mechanical thromus or kink rtc.)

    6 months

Secondary Outcomes (2)

  • Total number of dialysis sessions with active patent catheter usage

    6 months

  • Number of cases with venous thrombosis

    6 months

Study Arms (2)

Sodium bicarbonate Arm

ACTIVE COMPARATOR

In this arm, the catheter lock solution is sodium bicarbonate

Drug: Sodium bicarbonate

Heparin arm

ACTIVE COMPARATOR

In this arm, classic heparin will be used as a reference catheter lock solution (standard lock solution)

Drug: Heparin

Interventions

Dialysis catheter lumen will be filled (locked) by sodium bicarbonate solution. The amount of solution depends on the diameter and length and will be in accordance with the manufacturer's specifications.

Sodium bicarbonate Arm

Dialysis catheter lumen will be filled (locked) by classic heparin. The amount of pure heparin depends on the diameter and length and will be in accordance with the manufacturer's specifications.
