What action should be taken if a hematoma develops quickly during a venous draw?

If a hematoma develops quickly during a venous draw, the appropriate action is to release the tourniquet and stop the draw. A hematoma occurs when blood leaks out of the blood vessel and pools under the skin, usually due to the needle damaging the blood vessel or being improperly positioned. Continuing the blood draw in such a scenario could exacerbate the bleeding and lead to more significant injury or discomfort for the patient.

Releasing the tourniquet is crucial because it allows blood flow to normalize and helps reduce the pressure that may be contributing to the hematoma formation. Stopping the draw prevents further trauma to the vein and helps minimize the potential for complications. This corrective action is essential in maintaining patient safety and ensuring the best possible outcome during a blood draw procedure.
