Summary
A 25-year-old otherwise healthy male was involved in a motorcycle accident resulting in multiple long bone and pelvic fractures, and blood in his pelvis and abdomen. Massive blood loss occurred in the operating room, and the patient was rapidly transfused with 15 units of packed red blood cells (pRBC), 12 units of fresh frozen plasma (FFP), and two 6-packs of platelets. Despite the fluid resuscitation, the patient remained hypotensive. The astute resident in the case noted that the ionized calcium level on the last arterial blood gas was low and promptly administered 1 g of intravenous calcium chloride. The blood pressure rapidly improved. Why was the patient’s calcium low? Why did treating the hypocalcemia improve the blood pressure?
