Vascular Access: An Overview

Facts and insights about the use of peripheral vascular access for therapeutic apheresis

Think peripheral access first

Patient safety is a priority. Consider using peripheral access for your apheresis procedures.

"Peripheral venous access is underutilized in therapeutic apheresis procedures and is the access of choice due to the relatively low rate of serious complications.¹"

Did you know? 

Apheresis procedures

The majority of apheresis procedures can be performed successfully with peripheral veins.² 

Peripheral access

In several studies, apheresis procedures were performed peripherally in 64.3%³  to 94.6%⁴ of cases.² In some cases, peripheral access may not be feasible.⁵˒⁶

Spectra Optia

Red blood cell exchange and plasma exchange can be performed via single-needle or dual-needle peripheral access on the Spectra Optia™ Apheresis System. Not all options are available in all regions.

Vascular access in elective therapeutic apheresis²

USG-PIVA: Ultrasound-guided peripheral venous access

The chart shows the use of vascular access in elective therapeutic apheresis (including autologous and allogeneic hematopoietic progenitor cell harvest, mononuclear cell harvest, automated red blood cell exchange, therapeutic plasma exchange, and white blood cell depletion) and elective procedures as compared to emergency procedures.

Add to your knowledge and help optimize patient care with these best practices, resources, and education opportunities.

Putting peripheral venous access in action

By encouraging vein assessment as a standard practice before every apheresis procedure, you can help ensure that peripheral access is always considered as an option to meet a patient’s individual needs.

The impact of ultrasound-guided peripheral access

The use of ultrasound-guided peripheral venous access prevented the placement of central venous catheters in 20% of procedures, demonstrating its utility in a busy apheresis clinic.⁷

"In patients with difficult peripheral venous access, ultrasound guidance increased success rates of peripheral venous placement when compared with traditional techniques."⁸

Peripheral venous access tips and tricks

These handy tips and tricks can help when you are performing peripheral access. 

The information presented below is for your consideration only. Always follow your facility’s standard operating procedure for obtaining venous access.

Patient preparation and education
  • Perform a venous assessment
  • Set expectations — it may take more than one attempt to gain venous access
  • Educate your patients about:

    • Hydration prior to apheresis
    • Exercise when possible (for example, flexing fingers)
    • Use of topical anesthetics
Choosing needle gauge and flow rates

Select a needle or angiocatheter that will support the chosen flow rate.

Flow rates may vary based on the patient characteristics.

  • 17 gauge: 80 mL/min and above
  • 18 gauge: 70 mL/min and above 
  • 19 gauge: 60 mL/min and below
Vein selection and venipuncture
  • Assess arms for potential venipuncture sites
  • Palpate and visualize the vein for location, direction, and depth
  • Select a vein that will accommodate the needle size chosen

Prior to performing the venipuncture:  

  • Warm the venous site
  • Position the patient’s arm in a natural position
  • Use distraction techniques when inserting the needle
  • Stay calm 
  • Secure the needle; do not tape butterfly wings
  • Use an ultrasound-guided technique, if available
Maintain steady flow rates during the procedure

  • Use a blood pressure cuff or a tourniquet
  • Check the position of the patient’s arm and needle insertion sites
  • Encourage the patient to squeeze a ball or squeezer
  • Keep the patient warm
  • Warm the patient’s arm above and below the access site
Troubleshooting pressure alarms
  • Slow down the inlet pump flow rate
  • Ask the patient to squeeze
  • Check the pressure in the blood pressure cuff
  • Reposition the patient’s arm or the needle position
  • Verify the flow rate is appropriate for the vein and needle gauge
  • Ensure the patient is comfortable, warm, and calm
  • Check for obstructions along the inlet/return line
  • Establish alternate access
Repeated inlet/return pressure alarms on Spectra Optia
  • May cause the pumps to pause
  • May lengthen the procedure time
  • May cause clotting in the inlet site
  • Could lead to an inefficient procedure
  • 10 access alarms can increase your procedure by 15 to 20 minutes

Note: Pressing the Continue button without any other action will not fix the issue.
