Right Arm in Anatomic Position
ANTECUBITAL VEINS OF THE ARM USED FOR VENIPUNCTURE
1ST CHOICE = MEDIAN CUBITAL VEIN. It is usually the
largest, and best anchored. Least painful to puncture.
Least likely to bruise.
2nd CHOICE = CEPHALIC VEIN. It is usually harder to palpate
but is fairly well anchored. Often is the only vein that
can be palpated in obese patients.
3rd CHOICE = BASILIC VEIN. It is often the easiest to
palpate, but it is not anchored. Therefore it will roll and
bruise more easily. Venipuncture tends to be more painful
to patient. It has the highest possibility of accidental
puncture of the median nerve or brachial artery. Puncture
of the median nerve or brachial artery leads to possible
patient complications and lawsuits.
