S65.81

Clinical Causes: Sharp objects such as knives, glass, or metal that cause cuts on the wrist or hand Accidental falls or collisions resulting in injury to blood vessels Workplace incidents involving machinery or tools Animal bites or scratches that cause deep cuts Crushing injuries leading to tearing of blood vessels

Key Symptoms: Bleeding from the wound, which may be profuse depending on vessel involvement Pain at the injury site, often severe and sharp Swelling and bruising around the area Signs of tissue damage such as numbness or tingling Reduced or absent pulse in the fingers or hand, indicating compromised blood flow Possible visible deformity or the presence of a deep wound

Diagnosis Path: The diagnosis of a laceration involving blood vessels at the wrist or hand is primarily based on a physical examination. Healthcare providers will assess the wound and check for signs of impaired blood circulation, including pulse determination distal to the injury. Imaging studies like ultrasound or angiography may be used in more complex cases to evaluate the extent of vascular damage. Proper assessment helps determine if surgical intervention is necessary.

Treatment Protocols: Treatment aims to stop bleeding, repair injured blood vessels, and prevent complications. Typical approaches include: - Applying direct pressure and elevation to control bleeding - Cleaning the wound thoroughly to prevent infection - Suturing or stitching the wound to close it securely - Possibly performing surgical repair of damaged blood vessels - Administering antibiotics to prevent infection - Tetanus vaccination if indicated - Monitoring for signs of arterial or venous compromise - Follow-up care to assess healing and restore function In some cases, more advanced interventions such as vascular repair or ligation may be required. Rehabilitation may include physical therapy to regain strength and movement.
