Which method is NOT used to control bleeding?

Cauterization is the method that is NOT typically used to control bleeding in emergency situations. Instead, it is a surgical technique used to burn tissue to eliminate or close a wound or to stop bleeding by coagulating blood vessels. While cauterization can be effective in specific medical scenarios, it is not a first-line approach for managing acute bleeding in the field or non-surgical settings.

In contrast, direct pressure is the most common and immediate response to control bleeding, as applying pressure to the wound can help to slow or stop blood flow. Elevation also plays a role in controlling bleeding by reducing blood flow to an injured area if the injury is below heart level. The use of a tourniquet is an advanced intervention typically used for severe bleeding in limbs when other methods are ineffective. Each of these methods is focused on stopping bleeding quickly and effectively, making them essential techniques in emergency care.
