Summary
Venepuncture near the wrist can injure the superficial radial nerve, causing pain and nerve damage. Proper technique, including needle angle and vein selection, minimizes this risk.
Area of Science:
- Medical procedures
- Patient safety
- Nerve injury
Background:
- Venepuncture is a common medical procedure.
- Nerve injury is a potential complication during venepuncture.
- Superficial nerve injuries can cause significant patient discomfort and long-term sequelae.
Observation:
- A patient experienced severe pain and paresthesia during venepuncture of the cephalic vein in the left wrist.
- The superficial radial nerve was injured during the procedure.
- A flexed wrist position during venepuncture immobilizes the superficial radial nerve, increasing susceptibility to needle puncture.
Findings:
- Improper venepuncture technique, particularly with a flexed wrist, poses a risk of superficial radial nerve injury.
- Specific techniques, including appropriate vein selection and needle insertion angle (5-15 degrees), can mitigate nerve injury risk.
- Immediate cessation of venepuncture upon signs of nerve injury (electric shock sensation, vein rupture) is crucial.
Implications:
- Phlebotomists must be aware of the risk of nerve injury during venepuncture, especially in the wrist.
- Adherence to recommended venepuncture techniques is essential for patient safety.
- Prompt recognition and management of potential nerve injury can prevent further complications.
