Study Notes
Additional Factors Related to Vascular Pathology
- Structural damage occurs as a result of permanent scarring in major vessels, common in patients with placement of a fistula.
- Endothelial layer damage initiates collagen layer reactions and platelet activation requiring frequent vascular access procedures.
- Platelet plug.
Patient Assessment and Vein Preservation for Patients with Chronic Kidney Disease
- Activation of blood coagulation and platelets occur when a catheter tip infuses against the vein wall or repeated venipuncture.
- Cumulative damage, receiving hemodyalasis or ongoing exposure to caustic infusates is critical with repeated venipuncture.
- Upper extremity peripheral vein preservation is important for patients.
Osmolality and Venous Access
- Irritant or vesicant infusates or arteriovenous fistulas (optimal vascular access for hemodialysis)
- Extremes in prescriptions require good quality peripheral veins.
- Receiving other renal replacement therapy (Peritoneal dialysis, Kidney transplant).
Assessing for Previous Vascular Injury
- Assess for previous, permanent vascular injury that renders vein unusable for future hemodialysis vascular access including Stenosis or Thrombosis.
- Device selection criteria in CKD stage 3 or greater (eGFR of less than 60 mL/min/1.73 m2) or serum creatinine level greater than 2.0 mg/dL.
- Dorsal metacarpal veins in the dominant hand are preferred for short peripheral IV catheters.
- Veins in the forearm, upper arm, and subclavian are critical location for hemodialysis fistula or graft.
Peripheral Vein Access Procedures
- Veins in these areas (forearm, upper arm, and subclavian) should not be used for venous access procedures (PIV/PICC/Midline).
- These veins should be used only when future hemodialysis vascular access is unlikely.
- Consultation with healthcare teams.
- Avoid prolonged reliance on and implement alternative long-term venous access solutions as soon as possible.
Central Venous Access
- Internal jugular vein is preferred vessel for central venous access.
- Central access using a small diameter (< 8 Fr) catheter intended for long-term use (>1 week) should be via subcutaneous tunnel.
- Subcutaneous tunnel approach reduces the incidence of CLABSI.
Subclavian Vein Access
- Subclavian vein access is not routinely used in this patient population.
- Patient's upper extremity veins should be evaluated using ultrasound or venography.
- If determined to be unsuitable for hemodialysis graft or fistula, ipsilateral subclavian vein may be used after consulting a healthcare team.
