Removing the needle before the tourniquet can lead to several complications, including increased bleeding at the puncture site due to the pressure from the tourniquet being released. It may also cause discomfort or pain for the patient, as the pressure from the tourniquet can help stabilize the vein during needle withdrawal. Additionally, this practice can increase the risk of hematoma formation, as blood may leak into the surrounding tissue once the needle is removed. Proper protocol typically dictates that the tourniquet should be released before or simultaneously with needle withdrawal to minimize these risks.
