Giải thích
The basilic vein sits on the medial side of the antecubital fossa directly over the brachial artery and near the median nerve, so puncture there carries the highest risk of arterial nicking and nerve injury. Size, collapse tendency and valve count are not the deciding factors. When the basilic vein must be used, the needle is anchored carefully and the patient is monitored for shooting pain.
