Where is the site for hemostasis in case of massive hemorrhage from an open injury of the forearm?

For severe bleeding from an open injury in the forearm, hemostasis is generally achieved by bandaging at a location above the elbow, i.e., on the proximal side.

The tourniquet should be tied at the junction of the middle and upper one-third of the upper arm. The tourniquet should not be placed too low, as this may cause nerve damage. Patients can tie the tourniquet just below the deltoid muscle.

In addition, for some patients, it is important to accurately record the time when the tourniquet is applied. Continuous use should not exceed one hour. If further hemostasis is required after one hour, the tourniquet should first be loosened for 1–2 minutes before reapplying. The tightness of the tourniquet should be sufficient to stop the bleeding. After applying the tourniquet, patients must record the exact time of application. The tourniquet should not remain tied for more than 90 minutes; it must be released before reaching the 90-minute mark, and the release duration should exceed 10 minutes before the rubber tube can be used again for reapplication. During this process, patients should seek emergency medical treatment at a hospital as soon as possible.
