What is the maximum time a tourniquet can be left on a pt when searchinf for vein?
A tourniquet should typically not be left on a patient for more than 1 to 2 minutes when searching for a vein. Prolonged application can lead to tissue damage and complications such as nerve injury or ischemia. If the vein is not located within this timeframe, it's advisable to remove the tourniquet, allow circulation to return, and reapply if necessary after a brief period.

no longer than a minute and a half to two minutes once you get the needle into the vein you should tell the person to relax the fist first then remove the tourniquet if left on too long you can obliterate the blood supply and cause tissue damage
How long should a tourniquet be left on a pt arm during venipuncture procedure?
how long should a tourniquet stay on a patients arm:There is no clearcut rule as to how long a tourniquet may be inflated safely, although various investigators have addressed effects of ischemia on muscle and nerve to define a relatively "safe" period of tourniquet hemostasis. In practice, safe tourniquet inflation time depends greatly on the patient's anatomy, age, physical status, and the vascular supply to the extremity. Unless instructed otherwise, report to the surgeon when 60 minutes of tourniquet time has elapsed. There is general agreement that for reasonably healthy adults, 90 minutes should not be exceeded without releasing the tourniquet for a short time.
Why must a tourniquet be loosened from time to time?
A tourniquet must be loosened only in the event of a deep laceration. When one has been applied due to amputation, it should not be loosened. Loosening a tourniquet for a laceration, blood flow can continue continue to other tissue so that an amputation does not become necessary.
What is the role of Fibrin Sealant in knee replacement surgery?
To prevent bleeding instead of using a tourniquet. Potentially, this reduces recovery time as it reduces bruising at the site of the tourniquet.
How come that when you put a tourniquet on the arm it becomes gangrened?
A tourniquet cuts off blood flow. The arm or leg will not immediately become gangrenous. First, the skin would feel numb. The arm would begin to throb as if it 'went to sleep', with tingling, burning, etc. The person would likely be wiggling their fingers to get feeling back and would remove the tourniquet at that point, if lucid and not in shock from bleeding. If the restriction to blood flow was left on, the skin color and temperature would begin to change. The fingertips (or toes) would die first.
What happens when a tourniquet is left on too long during a venepuncture?
it causes a hematoma. Yes it does, but it also causes hemoconcentration & hemolysis.If a tourniquet is at high enough pressure and left on long enough, the tissues distal to the tourniquet may develop ischemia and gangrene, resulting in loss of those tissues.
