Why is a patient who is pronounced clinically brain dead given a syringe shot when removed from life support?

People are NOT given a shot with a syringe after being pronounced clinically brain dead. There are several instances I can think of that you could think a nurse was giving an injection to someone who is dead.

Let me explain:

If a person is on a ventilator, the tube in their mouth/throat is held in place with a balloon that is inflated. The only way to remove the tube is by deflating the balloon. A syringe--without a needle--is inserted into a special valve that allows the balloon to deflate.

The same process deflates the balloon that holds a urinary catheter in the bladder; the nurse draws back on the syringe to remove the normal saline in the balloon.

IVs in arms would just be removed without flushing the site with Normal Saline (NS).

Even when your loved one is pronounced dead, the family can still ask a nurse to explain what she is doing, whether it is removing a trach, an IV, or catheter. ASK.
