For the past several decades wet ice has been the common coolant used to maintain whole blood at 4 to 10 C during transit. This practice was introduced by the military during the early part of World War II, when whole blood was shipped from the United States to the War Zone. 1 The data presented herein, collected during recent field studies, show that a chemically produced refrigerant provides a satisfactory substitute for wet ice. A noteworthy advantage of this type coolant is that it may be produced independent of electrical current; especially important during disaster and power failure. The purpose of this paper is to further augment earlier work by McPeak and Camp. 2 The refrigerant was made from 12 pounds of a highly soluble crystalline, nitrogenous synthetic compound (CONH 2 ) mixed with 2,500 ml of water.
