S55.119

Clinical Causes: Direct trauma from sharp objects such as knives or glass Accidental cuts during activities like gardening, cooking, or handling tools Falls or blows that cause a sharp injury to the forearm Surgical procedures that inadvertently damage the radial artery Penetrating injuries from projectiles or stab wounds

Key Symptoms: Sudden and persistent bleeding from the forearm Pain or tenderness at the injury site Swelling and bruising around the wound Reduced blood flow to the hand, leading to pallor or bluish discoloration Loss of sensation or numbness in the fingers or hand Weak or absent pulse in the affected wrist or hand Potential signs of shock in severe cases

Diagnosis Path: Diagnosis typically involves a physical examination to assess bleeding, swelling, and pulse in the affected area. Imaging studies like Doppler ultrasound or angiography may be used to evaluate blood flow and locate the exact position of the laceration. Healthcare providers may also perform tests to check for nerve injury and ensure adequate circulation throughout the hand and wrist.

Treatment Protocols: Treatment priorities include controlling bleeding, preventing infection, and restoring blood flow. Common interventions include: - Applying direct pressure and, if necessary, using tourniquets to control bleeding - Cleaning and disinfecting the wound to prevent infection - Surgical repair of the lacerated artery, which may involve suturing or vascular grafting - Monitoring for signs of compromised circulation or nerve damage - Postoperative care with antibiotics and wound management - In cases of extensive injury, additional reconstructive procedures may be required to restore function and sensation Recovery depends on the severity of the injury and the promptness of treatment, with rehabilitation therapies potentially needed for optimal hand and wrist function.
