a. If the first attempt at venipuncture (penetration of the vein) is not successful
(no blood in the flash chamber, and so forth), pull the catheter/needle unit back slightly,
but do not pull the bevel above the skin surface. Attempt to direct the point of the
needle into the vein again.
b. If you are still unsuccessful, release the constricting band, withdraw the
catheter/needle completely, obtain another catheter/needle unit, and attempt another
venipuncture at a point proximal to (above) the previous attempt or on another limb.
c. If the second venipuncture attempt is not successful, obtain medical
assistance, if available. Do not attempt another venipuncture. If medical assistance is
not available, evacuate the casualty as soon as practical.
After the needle is removed, do not attempt to reinsert it
into the catheter. Reinsertion could cause a portion of
the catheter to be sheared off, enter the bloodstream,
and move to the heart where it could cause cardiac
d. Dispose of all used needles so that soldiers will not injure themselves on
them. If an appropriate waste container is available, use it. Otherwise, drive the needle
into the ground.
DOCUMENTING PROCEDURES ON A FIELD MEDICAL CARD
Document the initiation of IV fluids on DD Form 1380, United States Field
Medical Card. If you must leave the casualty or the casualty is being evacuated, tear
the original from the FMC pad and attach the card to the casualty (tie the wire onto the
casualty's clothing). Information on this form is found in Lesson 7.
DISCONTINUING AN INTRAVENOUS INFUSION
An IV may need to be discontinued because of evacuation, the fluid in the IV bag
being used up, or other reasons.
a. With Saline Lock. If a saline lock was established before the IV was started:
Adjust the clamp on the tubing so the flow of fluid is stopped.
