Neurologic recovery occurred in a 3-year-old patient following immersion hypothermia and prolonged cardiopulmonary resuscitation. Recognition of hypothermia in the near-drowning victim is imperative for appropriate resuscitative efforts. Intensive care monitoring (intracranial pressure, pulmonary artery catheterization) facilitates patient management and optimum neurologic recovery.

Deficiency of opsonic alpha 2 surface binding (SB) glycoprotein (cold-insoluble globulin, plasma fibrinectin) is related to depressed reticulendothelial function as well as to multiple organ failure after tissue injury and sepsis. Cryoprecipitate (250 ml), extracted from 10 units of human plasma, was infused over 60 minutes into 11 hypo-opsonemic patients with decreased renal function. Cardiac output, mean arterial pressure, creatinine clearance, and limb blood flow were measured before and at intervals of 14 to 20, 35 to 44, and 60 to 66 hours following cryoprecipitate infusion. ⋯ Limb blood flow increased significantly at 4 hours and returned to control values by 35 to 44 hours. Thus cryoprecipitate infusion to critically ill trauma and surgical patients with depressed renal function may improve glomerular filtration rate independently of mean arterial pressure or cardiac output. This improved renal function may be related to increased reticuloendothelial clearance of blood-borne particulates and/or improved microcirculatory function and lends support to the concept that RES failure may be involved in the etiology of multiple organ failure secondary to combined tissue injury and sepsis.
