S55.11

Clinical Causes: Sharp object injuries like knives or glass cuts Accidental trauma during sports or falls Penetrating injuries from industrial accidents Surgical procedures involving the forearm Trauma from physical altercations or violence

Key Symptoms: Initial bleeding that may be profuse or slow depending on the severity Palpable or visible swelling along the forearm Pain or tenderness at the injury site Discoloration or bruising in the surrounding area Reduced blood flow resulting in numbness or cold sensation in the hand Possible signs of distal ischemia such as pallor or weakness

Diagnosis Path: To confirm a radial artery laceration, healthcare providers typically follow a combination of physical examinations and diagnostic tests. These may include: - Visual assessment of the injury and bleeding - Palpation to detect any pulse deficits in the wrist or hand - Use of Doppler ultrasound to evaluate blood flow - Angiography in complex cases to visualize the extent of vessel damage A thorough assessment helps determine the severity of the injury and guides treatment planning.

Treatment Protocols: Management of a radial artery laceration involves several steps, tailored to the injury's severity: - Immediate pressure application to control bleeding - Elevation of the forearm to reduce swelling - Application of sterile dressings - Emergency transport to a healthcare facility for further care - Surgical intervention may be necessary to repair the artery, which can include: - Suture repair of the vessel - Ligation if repair isn't feasible - Possible use of grafts when extensive damage occurs - Postoperative care involves monitoring for signs of infection, ensuring proper limb blood flow, and managing pain - In some cases, antibiotics and immobilization may be prescribed to aid recovery Prompt medical intervention is critical to minimize complications and preserve hand function.
