If the bleeding is severe, a tourniquet may be necessary, but it should be used with caution and only as a last resort[2].
• Wound Cleaning: Once bleeding is controlled, the wound should be rinsed with clean water to remove debris and reduce the risk of infection. Avoid using alcohol or hydrogen peroxide, as these can further damage tissue[3].

2. Emergency Medical Services

• Seek Immediate Medical Attention: Given the potential severity of shark injuries, it is vital to seek emergency medical care as soon as possible. Emergency responders can provide advanced care, including intravenous fluids, pain management, and further stabilization of the patient[2][3].

Medical Treatment

1. Surgical Intervention

• Wound Repair: Depending on the extent of the injury, surgical intervention may be necessary to repair lacerations, remove foreign objects, or address any damage to underlying structures such as muscles, nerves, or blood vessels[3].
• Amputation: In cases of severe trauma where limbs are irreparably damaged, amputation may be required. This decision is made based on the extent of the injury and the potential for recovery[2].

2. Infection Prevention

• Antibiotics: Due to the high risk of infection from marine environments, prophylactic antibiotics are often administered to prevent infections, especially if the wound is deep or contaminated[3].
• Tetanus Immunization: Patients may also require a tetanus booster, particularly if their vaccination status is not up to date. This is crucial for any puncture or deep wound[4].

Long-Term Management

1. Rehabilitation

• Physical Therapy: Following initial treatment, patients may need physical therapy to regain strength and mobility, especially if there has been significant tissue loss or amputation[3].
• Psychological Support: Shark attack survivors may experience psychological effects, including post-traumatic stress disorder (PTSD). Counseling and support groups can be beneficial in addressing these issues[2].

2. Follow-Up Care

• Regular Check-Ups: Ongoing medical evaluations are essential to monitor healing, manage any complications, and adjust rehabilitation plans as necessary[3].
