W56.21

Clinical Causes: Close interaction with orcas in captivity, such as in aquariums or marine parks Research or conservation activities involving wild orcas Accidental encounters during boating or marine activities Threatened or agitated behavior by the whale, possibly due to stress or perceived threats Misunderstanding or miscommunication between humans and the whale

Key Symptoms: Lacerations and puncture wounds from teeth Bleeding at the site of the bite Swelling and redness around the wound Pain and tenderness in the affected area Potential infection if the wound is not properly cleaned Signs of shock in severe cases, such as weakness, rapid heartbeat, or dizziness

Diagnosis Path: Diagnosis involves a physical examination of the injury site, assessing the severity of the wounds, and possibly imaging studies such as X-rays to check for deep tissue damage or embedded teeth fragments. Medical professionals will also evaluate for signs of infection or other complications. A detailed history of the incident and the whale's behavior may be helpful in understanding the injury’s context.

Treatment Protocols: Treatment for an orca bite typically includes the following steps: - Immediate wound cleaning to remove debris and reduce infection risk - Administration of antibiotics to prevent or treat infection - Tetanus vaccination if the wound is dirty or the patient's immunization status is not current - Repair of deep lacerations, possibly through suturing - Pain management with appropriate medications - Monitoring for signs of infection, such as increased redness, swelling, or pus - Surgical intervention if necessary for extensive tissue damage or foreign body removal - Follow-up care to ensure proper healing and to address any complications In some cases, rabies or other zoonotic diseases are not typically associated with orca bites, but consultation with infectious disease specialists may be necessary if there are suspicious exposures.
