AbstractA prospective study was undertaken to determine the change in coagulation factors in patients undergoing tangential excisions of burn wounds when red blood cells preserved with ADSOL (adenine, dextrose, saline, and mannitol) and crystalloid solution were used for volume replacement. Nine patients with burns were studied, three on two separate occasions. No patient had a history of a bleeding disorder or had taken aspirin within 10 days of surgery. Results of preoperative coagulation studies were all within normal limits. The initial levels of coagulation factor and rates of removal were compared with those of 12 patients without burns who were undergoing elective surgery and who also had massive intraoperative blood loss. Coagulation factor levels measured included the platelet count, fibrinogen, factors V, VIII, and IX. These were determined before blood loss and each time loss and replacement of one third of a patient's calculated blood volume occurred during a tangential excision of a burn wound. The data showed that patients with burns have significantly higher baseline levels of platelets, fibrinogen, and factor VIII than patients without burns do. The removal rates of platelet and factor IX are significantly lower among patients with burns than among patients without burns. No patient in the study group developed a coagulopathy or received fresh frozen plasma or platelet supplementation. These findings suggest that the intraoperative blood losses that occurred during tangential excisions of burn wounds were made safe by the higher than normal preoperative levels of platelets, fibrinogen, and factor VIII and by the slow wash-out curve for platelets and factor IX. Prophylactic use of either fresh frozen plasma or platelet concentrates is not indicated unless a specific deficit or coagulopathy has been identified.
