For all patients with critical bleeding requiring massive transfusion, the use of a Massive Transfusion Protocol (Massive Transfusion Protocol) to facilitate timely and appropriate use of Red Blood Cells (pRBC) and other blood components may reduce the risk of mortality and Acute Respiratory Distress Syndrome (ARDS).ScopeAlertsLink to: Massive Transfusion Flow ChartLink to : Massive Transfusion Activation – Responder after hoursMeasurement of ParametersMeasurement of parameters should be repeated after every 4-6 red cell units transfused. Consultation with Haematologist Consultation with haematology should take place to confirm appropriateness of optimal conventional therapy for coagulopathy and the appropriate dosage of rFVlla. Tranexamic AcidIn CRASH-2 study tranexamic acid given after 3 hours after injury was associated with an increased risk of death caused by bleeding (4.4% vs.3.1%);Possible adverse effects Hypotension with rapid intravenous administration. Increased risk of thromboembolic events Tranexamic acid should not be administered in the same line as blood products.Contraindications:Injury greater than 3 hours agoPatients less than 16 years of agePregnancyIsolated closed head injuryKnown thromboembolic diseaseDisseminated Intravascular Coagulation (DIC)Obstetric Haemorrhage In the setting of major obstetric haemorrhage, early administration of cryoprecipitate or fibrinogen concentrate may be necessary; and Aim to keep the fibrinogen level >2g/L for obstetric patients.Recombinant Factor VIIa (rFVIIa)Dosage rFVIIa (90 mcg/kg)should only be considered in the event of failure to obtain haemostasis, where: Platelet and fibrinogen levels are adequate;Bleeding continues; andAll appropriate surgical and embolisation procedures have been attempted.Management of severe acidosis should be considered prior to administration of rFVIIa ScopeThis procedure pertains to all staff involved in the care of patients with critical bleeding within the Canberra Hospital and Health Services. Due to the unique environment of the pre-hospital Retrieval Service (South Care), which has dual reporting lines to ACT Ambulance Services, the initiation and administration of Emergency O Rh (D) negative red blood cell units in a critical bleeding in a retrieval situation will be covered in Retrieval (South Care) procedure. Haematologist ResponsibilitiesLiaise regularly with laboratory and clinical team; and Assist in interpretation of results, and advise on blood component support. Medical Officers ResponsibilitiesDetermine that patient meets criteria for Massive Transfusion Protocol activation;Notify transfusion laboratory of Massive Transfusion Protocol activation x 44239;Ensure availability of pathology specimens for the purpose of measuring parameters;Comply with Blood and Fresh Blood Product Administration Procedure; andNotify laboratory when Massive Transfusion Protocol can be stood down.NursesResponsibilities:Comply with Blood and Fresh Blood Product Administration procedure.Laboratory ScientistsResponsibilities:Notify haematologist of activation of Massive Transfusion Protocol;Prepare and issue blood components as requested;Anticipate repeat testing and blood component requirements; Minimise test turnaround times; andConsider staff resources. Wards person/CouriersResponsibilities:Prioritise transport of specimens and blood products to minimise test turnaround times for both specimens to the transfusion laboratory and blood components to clinical areas; andConsider staff resources (dedicated person to support Massive Transfusion Protocol).Activation of the Massive Transfusion Protocol should take into account:Cause and rate of the haemorrhage; Mechanism of injury (if present);Current physiological state; and Likely requirement for ongoing blood component support.Section 1 – Tranexamic AcidTranexamic acid Alert:Loading dose of tranexamic acid 1 gram in 100mL sodium chloride 0.9% over 10 minutes, followed by infusion of tranexamic acid 1 gram in 100mL sodium chloride 0.9% over 8 hours Tranexamic acid given after 3 hours after injury may be associated with an increased risk of death caused by bleeding;Possible adverse effects include hypotension with rapid intravenous administration.The risk of thromboembolic events may increase.Tranexamic acid should not be administered in the same line as blood products.ContraindicationsInjury greater than 3 hours agoPatients less than 16 years of agePregnancyIsolated closed head injuryKnown thromboembolic diseaseDisseminated Intravascular CoagulationTranexamic AcidIn trauma patients with or at risk of significant haemorrhage, tranexamic acid should be used, ideally within the first one hour since injury Use within 3 hours from time of accident for all trauma patientsJudged to be 16 years or older,Significant haemorrhage Systolic blood pressure less than 90 mmHg and/or heart rate more than 110 beats per minute or Who have either significant haemorrhage, or who are considered to be at risk of significant haemorrhageEquipmentTranexamic acid 1 gram ampoule with diluent x 210mL syringe Sodium chloride 0.9% 100mL x 2Infusion pumpIntravenous administration setProcedureLoading dose of tranexamic acid 1 gram in 100mL sodium chloride 0.9% over 10 minutes, followed by infusion of tranexamic acid 1 gram in 100mL sodium chloride 0.9% over 8 hours Back to Table of Contents Section 2 – Massive Transfusion In critically bleeding patients requiring, or anticipated to require, massive transfusion, a Massive Transfusion Protocol should be used.Activation of the Massive Transfusion Protocol should take into account:Cause and rate of the haemorrhage; Mechanism of injury (if present);Current physiological state; and Likely requirement for ongoing blood component support.EquipmentPathology specimen tubes and request formsEDTA TubeCitrate tubeArterial Blood Gas syringeBlood productsBlood warmerForced air warming blanketWarming mattressTranexamic acid 1 gram with diluent10mL syringe100mL sodium chloride 0.9%Infusion pumpBlood pump infusion setProcedureIdentify Patients requiring Massive Transfusion Protocol ActivationPotential patients are recognised as those suffering uncontrolled haemorrhage and coagulopathy. This will usually be in the setting of a massive transfusion represented by features such as:Immediate need for, or prior transfusion of, immediate release uncrossmatched (usually O Rh (D) negative) pRBC due to rapid haemorrhage and anaemia;Blood loss exceeding 150 mL/min;The need for at least four pRBC units within 4 hours in the setting of continuing uncontrolled bleeding;Replacement of 50% of the total blood volume within 3 hour (approximately 35mL/kg in an adult patient);Replacement of the blood volume within a 24-h period; this corresponds to about 70 mL/kg of body weight, or 5 litres in a 70kg patient;Presence of diffuse micro vascular bleeding; andThe need for plasma and/or platelet replacement.Alert: It is recognised that massive trauma or pre-existing coagulopathy may induce massive non-surgical bleeding at losses less than these. Where there is a pre-existing coagulopathy, specific early correction is advised.Notify Transfusion Laboratory The medical officer notifies the transfusion laboratory of activation Massive Transfusion Protocol, phone number 6244 2918 or 44239;Once a patient has been identified as requiring massive transfusion, blood tests to measure parameters should be labelled as Urgent Massive Transfusion; The transfusion laboratory will notify the on-call haematologist; The laboratory to thaw Fresh Frozen Plasma (FFP). Four group specific pRBC units may be requested if current cross match sample available; andThe laboratory will issue Red Cells to Plasma at a 1:1 ratio unless directed otherwise by the haematologist on call.Measure parametersThe following parameters should be measured early and frequently: Temperature;Acid–Base Status;Ionised Calcium;Haemoglobin;Platelet Count;PT;APTT; andFibrinogen LevelAlert: These should be repeated after every 4-6 red cell units transfused. With successful treatment, values should trend towards normal.Values indicative of critical physiologic derangement include: Temperature < 35°C;pH < 7.2, base excess > – 6, lactate > 4 mmol/L;Ionised calcium < 1.1 mmol/L;Platelet count < 50 × 109/L or < 100 x 109/L in head injury;PT > 1.5 × normal;APTT > 1.5 × normal; andFibrinogen level < 1.0 g/L or <2.0g/L in obstetric haemorrhage.The majority of patients will initially be volume resuscitated with crystalloid, or possibly colloid: Red cells are used as anaemia develops. These may be uncrossmatched (group O). In general, group specific red cells should be used as soon as they are available. Transfusion of platelets is less predictable, and usually occurs much later with dilutional coagulopathy. Cryoprecipitate is often unnecessary in simple dilutional coagulopathy if plasma is replaced adequately; however, DIC with hypofibrinoginaemia should prompt aggressive replacement therapy.Ensure surgical definitive haemostasis procedures to arrest active bleeding are considered.If mixed surgical and non-surgical bleeding continues in spite of treatment, initiation of damage control surgery should be considered, especially if the:pH <7.2 and/or; HCO3 < 15 mmol/L;Core body temp < 34°C; andThere is ongoing coagulopathy.This usually includes abandonment of definitive surgical repair, rapid haemostasis, packing and closure. The patient is then transferred to ICU for warming, coagulopathy and inotropic management. A later definitive procedure is then undertaken. This may include: Operative surgical exploration;Orthopaedic fixation; andEmbolisation by interventional radiology.Initiate measures to prevent and reverse hypothermiaUtilise Blood/fluid warmers; andUtilise forced air warming blanket and warming mattress or under patient warmers.This equipment is available from acute care environments, e.g. Resuscitation room, Operating Rooms, Intensive Care Unit.Initiate measures to prevent and reverse acidosisPrevention of tissue hypoxia is primarily used to prevent acidosis in the acute setting. In ICU, haemodialysis may be considered. Specifically Correct Coagulation DeficienciesThe use of platelets and cryoprecipitate is generally guided by laboratory tests. However, coagulation testing and thawing of plasma products of necessity introduce significant delays in product availability, so empirical use of coagulation factors may be necessary in certain circumstance.Frozen plasma products are thawed under controlled conditions to ensure the viability of the coagulation factors they contain. Consequently there is a delay of 20-30 minutes from the time of request until availability. Use may need to be anticipated; and Cryoprecipitate is used primarily as a source of fibrinogen (but also contains FVIII, VWF and FXIII). This is found in adequate amounts in FFP, and in dilutional coagulopathy FFP alone may be adequate. Coexisting DIC may increase fibrinogen requirements. Empirical use is unnecessary. Use should be guided by fibrinogen determinations.Back to Table of ContentsSection 3 – Stand down of Massive Transfusion Protocol It is important to inform the transfusion laboratory that the massive transfusion protocol is stood down. Contact phone number x44239Massive transfusion protocol may be stood down when the treating team consider the patient to be haemodynamically stable and urgent blood/ blood products support is no longer required.Alert:Obstetric Haemorrhage In the setting of major obstetric haemorrhage, early administration of cryoprecipitate or fibrinogen concentrate may be necessary; and Aim to keep the fibrinogen level >2g/L for obstetric patients.Recombinant Factor VIIa (rFVIIa)rFVIIa (90 mcg/kg) should only be considered in the event of failure to obtain haemostasis, where: Platelet and fibrinogen levels are adequate;Bleeding continues; andAll appropriate surgical and embolisation procedures have been attempted.ConsultationConsultation with on call haematologist should take place to confirm appropriateness of optimal conventional therapy for coagulopathy and the appropriate dosage of rFVlla. (Contact on call haematologist via Switch 62442222)Follow upPatients should be considered for management in the intensive care unit following massive transfusion, where attention to perfusion and early identification of bleeding or oozing should be undertaken, particularly as further dilution may occur until volume is replaced. Replacement of coagulation factors is not necessary unless there is active bleeding. In the event of bleeding transfusion should aim to keep:Hb>80g/L;Platelets >50x109/L; and PT and APTT<1.5 x control.Back to Table of ContentsSection 4 – Massive Transfusion Activation – Responder after hoursSection 5 – Massive Transfusion Flow chartImplementation Medical Nursing OrientationWard level in services conducted by Transfusion CNC and local areas CNC/CMCCommunication VIA NQSHS SCOOPBack to Table of ContentsRelated Policies and Standard Operating ProceduresAustralia and New Zealand Society of Blood Transfusion Ltd 5th ed 2007.
