What interventions should NOT be performed when treating a snakebite?

When treating a snakebite, cutting or sucking the envenomation site is strongly discouraged. This intervention is based on outdated practices that have been shown to be ineffective and potentially harmful. Cutting the skin can lead to additional tissue damage, increased risk of infection, and further spread of the venom into the bloodstream. Similarly, attempting to suck out the venom does not effectively remove it and can introduce bacteria from the mouth into the wound, worsening the victim's condition.

In contrast, applying a cold compress is often used to alleviate pain and swelling, although it should be done with caution to avoid frostbite. Administering test doses of antivenom is not a standard practice as it may cause allergic reactions; therefore, definitive antivenom treatment should only be given by trained medical professionals after evaluation. Keeping the affected limb immobilized is a recommended intervention, as it helps to slow the spread of venom through the lymphatic system. Familiarity with these guidelines is essential for effective and safe management of snakebites in emergency settings.
