From January 1982 through December 1983, 83 severely injured and hypovolemic patients were immediately resuscitated with uncrossmatched packed red cells. Seventy-four patients received 250 units (3.3 units/pt) of Group O red blood cells (TOB), and nine patients received 27 units of type-specific blood (TSB) (3.0 units/pt). Additionally, 53 units of TSB were transfused to the TOB group in the interval between TOB immediate transfusion and the availability of fully crossmatched blood. A total of 880 units (10.6 units/pt) were transfused without instance of transfusion reaction or subsequent crossmatching difficulty. The protocol called for two units of TOB (Rh positive for males, Rh negative for females) to be delivered to the resuscitation area before patient arrival. The decision to transfuse TOB was left to the surgeon in charge and was based on the clinical impression of severe shock. Thirty-eight per cent (31 patients) met the criteria of requiring a 'massive transfusion' (greater than 10 units within 24 hours). Overall, 28 patients (31%) died, 22 within hours of arrival. No death was attributable to transfusion reaction or blood incompatibility. Complications included one dysrhythmia, six patients developed ARDS (7.2%), and ten patients (12%) had 'DIC'. Two patients developed positive hepatitis screens, and there was one clinical case of hepatitis observed. None of the 'DIC' cases were related to incompatible blood transfusion. We conclude that for immediate trauma resuscitation, TOB is safe and TOB has additional advantages over TSB or Type O whole blood transfusion.(ABSTRACT TRUNCATED AT 250 WORDS)

Despite an excellent military experience with the use of the "universal donor" as an immediately available blood component, considerable reluctance to use uncrossmatched Group O packed cells (TOB) remains. In addition, problems continue with rapid blood acquisition in the emergency department. To study the safety of TOB used as an immediate resuscitation component, a 30-month prospective study of all patients arriving at a single trauma unit was undertaken. By protocol TOB (O-, female; O+, male) was delivered to the shock room prior to patient arrival and was expanded to 500 mL by adding 250 mL prewarmed saline (39.4 C) to the existing RBC unit. Transfusion was ordered on clinical signs of Class III or Class IV hemorrhage. Ninety-nine patients entered the protocol, receiving a total of 1,136 units of blood (11.5 units/patient). Four hundred ten units (4.1 units/patient) of uncrossmatched blood were administered on patient arrival--322 units of TOB and 88 units of type-specific blood (TSB). Seven patients (7.4%) had prior transfusions, and 14 (58%) women had prior pregnancies. Complications included disseminated intravascular coagulation, 12%; adult respiratory distress syndrome, 8%; and hepatitis, 1%. Forty-nine patients (49%) required massive transfusion (greater than 10 units/24 hr). All patients were followed clinically and by the blood bank for any signs of transfusion reactions or incompatibility throughout their hospital courses; none developed. There were no deaths related to transfusion incompatibility. We conclude that TOB used as an immediate resuscitative blood component is safe.(ABSTRACT TRUNCATED AT 250 WORDS)
