There is consensus that the platelet count should not beallowed to fall below 50 · 10 9 / L in patients with acutebleeding (BCSH, 1988; Consensus Conference onPlatelet Transfusion, 1998; Stainsby et al, 2000).A higher target level <strong>of</strong> 100 · 10 9 / L has beenrecommended <strong>for</strong> those with multiple trauma or centralnervous system injury (Development Task Force <strong>of</strong> theCollege <strong>of</strong> American Pathologists, 1994; Horsey, 1997).Cryoprecipitate:Cryoprecipitate is a blood fraction containing concentratedfibrinogen (factor 1), fibronectin, factor <strong>VIII</strong> and VonWillebrand Factor and is the definitive therapy in fibrinogendeficiency. Serial estimations <strong>of</strong> fibrinogen, PT and APPT aremandatory. Fibrinogen levels should be maintained above 1g/l. Average replacement would be 1 unit/5 kg. body weight(15 to 20 units <strong>for</strong> an adult).Fresh frozen plasma (FFP):FFP is indicated in Acute Disseminated IntravascularCoagulation (DIC) or during Massive Transfusion where DICis anticipated. When PT and APPT are prolonged to more53
