LEEDS TEACHING HOSPITALS TRUST eClinical Guidelines Template Transfusion in massive haemorrhage in trauma (Adults) Guideline Detail Ownership Jonathan Jones, Consultant in Emergency Medicine (contact for review) Fran Hartley, Transfusion Practitioner Publication date October 2010 (updated version: Oct 2013) Next Review date October 2016 Summary For adult patients with massive haemorrhage as a result of traumatic injury better outcomes are achieved by the use of early, aggressive blood component resuscitation. Aims To improve outcome in victims of major trauma through the use of appropriate and timely blood component transfusion. To minimise wastage of blood components. Objectives To provide clear guidance to clinical teams managing victims of major trauma on what to transfuse, when to give it and how to request it. Background An accumulating body of evidence and expert opinion supports earlier use of blood components in the resuscitation of patients with massive haemorrhage as a result of traumatic injury. Packed red blood cells and fresh frozen plasma (FFP) should be given in a ratio of 2:1 (or less). Platelets and cryoprecipitate are also necessary following large volume blood product resuscitation. It is vital that scarce blood component resources are used appropriately. This document must be used in conjunction with the LTHT Policy on Safer Transfusion Procedures, http://nww.lhp.leedsth.nhs.uk/common/guidelines/detail.aspx?ID=1864 and the Policy for the use of written informed consent for transfusion of blood and blood components http://nww.lhp.leedsth.nhs.uk/common/guidelines/detail.aspx?ID=1217 and the Guideline for Generic Management of Massive Haemorrhage, http://nww.lhp.leedsth.nhs.uk/common/guidelines/detail.aspx?ID=2275 (adults) Diagnosis The massive haemorrhage in trauma protocol should be activated when: Systolic BP < 90mmHg following initial crystalloid resuscitation (no more than 2 litres) AND There is suspected active haemorrhage AND A consultant with experience in the management of major trauma authorises its use. Investigation This guideline does not cover the investigation of the source of the bleeding but assumes that all appropriate measures to identify and stop the bleeding are ongoing. For details on appropriate investigations in the management of massive haemorrhage see the above referenced policies. Treatment / Management This guideline does not cover the management of bleeding in trauma per se but rather the appropriate use of blood components for the resuscitation of victims of major trauma. The guideline assumes that all necessary measures to identify and control bleeding sites are ongoing. Furthermore effort must be directed at preventing hypothermia by the use of fluid warmers and external warming devices (eg Bair hugger). To improve confidence and maintain best practice when managing massive haemorrhage, it is strongly recommended that teams hold regular (at least annually) ‘dry-runs’ / ‘drills’ to practice individual team member roles in a massive haemorrhage scenario and to ensure a cohesive team approach in managing patient A successful outcome requires prompt action and good communication between clinical specialities, diagnostic laboratories, blood bank staff and the local blood centre. Correctly labelled blood samples, early surgical involvement and an emphasis on acute haemorrhage control are key to patient survival. A member of the clinical team should be nominated to act as co-ordinator responsible for overall organisation, liaison, communication and documentation. This is a critical role for a designated member of the permanent clinical staff. A checklist with the recommended order of actions for the co-ordinator to follow can be found in Appendix 1. 1. Call blood bank (x23398). Give patient details (including whether more than 1 casualty). State: “This is a massive haemorrhage” & request “Massive Transfusion Pack 1”. Avoid any further calls to blood bank unless the situation changes. 2. Ensure CORRECTLY LABELLED patient ID wristband is in place (preferably, detailing the patient’s NHS number as the primary identifier. No wristband, no transfusion). 3. Ensure CORRECTLY LABELLED transfusion sample taken. This should be taken to blood bank on A-Floor of Jubilee Wing by hand as this is the fastest route and allows confirmation that the sample is acceptable. DO NOT use the point to point airtube. 4. At the same time, take samples for FBC, clotting screen and U&E and send to Blood Sciences Lab in Old Medical School by point to point airtube 5. While awaiting the massive transfusion ‘pack’, use Emergency O -ve blood from the Emergency Department supply if immediate red cell transfusion is essential. Aim for a balanced resuscitation approach if no significant head injury. Once the decision to activate the massive transfusion in trauma protocol has been taken aim to avoid using additional crystalloid or colloid. NB: It is recommended to use A&E staff to run/collect blood components during an emergency and not to rely on the general portering service 6. Massive transfusion pack1 consists of 8 units red cells and 4 units Fresh Frozen Plasma (FFP). Give red cells and FFP in a 2:1 ratio. Transfuse FFP alongside red cells using separate IV access. 7. After 4 units red cells have been given the senior clinician must decide whether the second massive transfusion pack is required. If it is contact blood bank and request “Massive Transfusion Pack 2”. 8. When massive transfusion pack 1 is given administer intravenous tranexamic acid 1g over ten minutes (so long as it’s within 3 hours of the injury) followed by another 1g over the next 8 hours. 9. Massive transfusion pack 2 consists of 8 red cells, 4 units FFP, I adult dose of platelets and 2 pools of cryoprecipitate. If any of the red cells of massive transfusion pack 2 are given the adult dose of platelets and the cryoprecipitate must also be given assuming the patient’s fluid status will allow for this. Do not wait for blood results but be guided by the clinical assessment of the ongoing need for fluid resuscitation. 10. Following the administration of platelets, cryoprecipitate and the majority of the red cells and FFP ensure a repeat clotting screen and FBC are sent to haematology. This will guide further blood component administration. 11. Further blood components should be requested as needed guided by blood results and in liaison with doctor on call for haematology. 12. Any unused blood components MUST be returned to blood bank immediately 13. All red cells received in Resus must be checked into the blood fridge. Or, if blood arrives in a cool box it should be kept in the cool box in which it arrives for up to the maximum length of time stated on the transport slip. Each blood unit should be removed and used one at a time, between each removal ensure the lid is securely positioned on the cool box at all times. Platelets MUST NOT be cooled. 14. All blood components must be recorded on a transfusion prescription and fated using the Autofate system or by signing and sending the manila tag attached to each blood component. 15. Patients on warfarin with significant bleeding from trauma should be given 25 international units / kg of intravenous Prothrombin Concentrate Complex (PCC) i.e. Beriplex/Octaplex (requested on the PCC request form - see: http://lthweb/sites/hospital-transfusion-team/how-to-orderblood-and-blood-products/Product%20Order%20form%202010.pdf) assuming they do not have an absolute contraindication to reversal. Do not wait for an INR result before giving the Octaplex. Remember that PCC has a short half life (4-6 hours). If longer term reversal is indicated give 5mg (slow bolus) intravenous vitamin K as well. For further information see: http://nww.lhp.leedsth.nhs.uk/common/guidelines/detail.aspx?ID=550 16. Because of the large citrate load from anticoagulated blood components, ionised hypocalcaemia may occur, especially if there is liver synthetic dysfunction. This may interfere with coagulation and have other adverse metabolic consequences. Ionised calcium can be reliably measured on a blood gas machine. This may be corrected by intravenous infusion of calcium chloride. A dose of 10ml 10% calcium chloride has been recommended, alternatively 2.5 to 5.0 mmol in divided doses over 10 minutes followed by repeat of the assay. 17. All activations of the massive transfusion protocol in trauma must be reviewed as part of the departmental trauma clinical governance procedure.

Robust experimental or observational studies De-briefing It is a requirement of the NPSA Alert RRR 017 that clinical areas involved hold a ‘de-brief’ after each massive haemorrhage case to establish any learning points and/or if any changes in practice are required to improve the outcome in future massive haemorrhage situations. The de-brief should be initiated by the Consultant in charge and/or the Hospital Transfusion Team. Feedback on any lessons learned will be circulated to relevant stakeholders by the Consultant in charge and/or the Hospital Transfusion Team. The de-brief group should consist of all key stakeholders including representation from the Hospital Transfusion Team and Transfusion lab to enable a full and robust analysis of the approach to the massive haemorrhage case.

Or, LGI Blood bank will automatically arrange for porters to collect/deliver urgent blood components Prompt communication is vital to patient outcome during massive blood loss. The choice of wording is key to a speedy delivery of blood and its components, try to avoid using ‘as soon as possible’ which can lead to ambiguity. If you require blood components immediately you will need to request them ‘IMMEDIATELY’.
