How to take blood from a baby

First, send its parents out of the room.
Amir* is a 9-week old baby boy who has been losing weight since his mother stopped breast-feeding him at 6 weeks. He is now back to his birth weight. He lies in his cot sucking contentedly on a dummy. His baby-gro hangs off him, as does his very skin. He is missing patches of hair from where scalp veins have been cannulated before. Danny*, the senior SHO, knots a small piece of gauze around Amir's arm as a tourniquet. He is crying even before the needle has come out of its sterile packet. Danny bends the tiny wrist forward until the hand is almost doubled back on the arm. The needle pierces his skin and he bawls. He kicks with all his might, but Danny has got his arm pinned to the cot with two fingers.
We finally get into a vein on the third attempt. The veins are so delicate and collapsible that you have to just wait and let the blood drip out. Amir stops crying and takes the dummy in his mouth again. He seems to have forgotten the whole ordeal.
