Cadaver blood is perfectly suitable for transfusion into living human donors. With due precautions and autopsy control, the procedure is innocuous and beneficial. Blood should be drawn within 6 hrs. after death. This may be performed in the autopsy room, for only a simple venipuncture is necessary. It should be stored according to U. S. blood banking regulations and used within 21 days after acquisition. It should be drawn from a neck vein (preferably the right internal jugular) with the body in a head-down tilted position. Because small postmortem clots may occasionally limit the total drawn, larger bore needles might facilitate flow. Any apparently healthy person who dies suddenly is a candidate for donation. Complete autopsy must be assured. Ideal instances involve closed injuries or internal catastrophes, such as heart attacks, drowning, suffocation, and even acute alcoholic intoxication. Minor cuts and occasional deep penetrating trauma are not contraindications as long as there has been no extensive hemorrhage.
