🩸 Nerve Injury During Blood Collection: A Rare Complication That Every Healthcare Professional Should Know
Venepuncture is one of the most frequently performed invasive procedures in healthcare. While generally safe, nerve injury remains a recognised but uncommon complication that can result in significant discomfort, temporary disability, or, in rare cases, permanent neurological impairment.
As healthcare professionals, our commitment extends beyond obtaining a successful blood sample—it includes protecting patients from preventable complications through sound clinical knowledge and evidence-based practice.
🔍 Possible Causes of Nerve Injury
Nerve damage during blood collection may occur due to:
• Direct needle trauma to a nearby peripheral nerve.
• Insertion at an incorrect angle or excessive needle depth.
• Multiple unsuccessful venepuncture attempts causing tissue trauma.
• Anatomical variations where nerves lie closer to superficial veins than expected.
• Formation of a haematoma that compresses adjacent nerves.
⚠️ Clinical Signs & Symptoms
Patients may report:
• Sudden sharp, electric shock-like pain during needle insertion.
• Burning sensation radiating along the limb.
• Tingling or numbness (“pins and needles”).
• Weakness or reduced movement of the affected limb.
• Persistent pain or altered sensation lasting beyond the procedure.
Immediate recognition is essential. If a patient experiences sudden radiating pain during venepuncture, stop the procedure immediately and withdraw the needle.
🩺 Management
Recommended management includes:
âś… Cease the procedure immediately.
âś… Assess and document neurological symptoms.
âś… Apply a cold compress if appropriate to minimise swelling.
âś… Provide reassurance and appropriate analgesia according to clinical protocols.
âś… Arrange medical review if symptoms persist, worsen, or motor weakness develops.
âś… Document the incident thoroughly and follow institutional reporting procedures.
Most minor nerve injuries resolve over days to weeks; however, persistent neurological deficits require prompt specialist evaluation.
âś… Prevention Starts with Good Practice
Preventing nerve injury begins with:
✔️ Thorough knowledge of upper limb vascular and nerve anatomy.
✔️ Appropriate vein assessment before needle insertion.
✔️ Correct needle angle and insertion depth.
✔️ Limiting repeated venepuncture attempts and seeking assistance when necessary.
✔️ Avoiding high-risk anatomical areas whenever possible.
✔️ Maintaining competency through continuous education and practical skills training.
Every blood draw is an opportunity to demonstrate safe, patient-centred care. Technical excellence and clinical vigilance remain the best tools for preventing avoidable complications.
