Major haemorrhage protocol

Massive haemorrhage

Access nearest available Group O Negative units
Give 20ml/kg blood when available, 20ml/kg FFP and 5ml/kg cryo should be given. 
This does not require coagulation screen results. 
Give 10ml/kg platelets when available.

Continue transfusion to achieve:
Hb > 80g/l
Platelets > 75 x 10⁹
Fibrinogen > 1.5 g/l (if not, transfuse 5ml/kg of cryo)
APTT/PT <1.5 x midpoint of normal (if not, transfuse 20ml/kg of FFP)

Additional interventions

Consider tranexamic acid 15mg/kg infused over 15 minutes followed by 2mg/kg infusion, for at least 8 hours or until bleeding stops. This treatment can be started within 3 hours of haemorrahage.

Novo 7, Recombinant factor VIIa (rFVIIa) – although current recommendation is that Novo 7 is not for use outside licensed indication, consideration should be given to its use where treatment options are limited and patient is exsanguinating. Please contact Consultant Haematologist.

Management of adverse complications 

The following complications should be anticipated and managed appropriately in patients receiving multiple units of blood components.

Hypothermia – monitor temperature, keep patient warm. Consider active warming.

Hyperkalaemia – monitor potassium, initiate local protocol for treatment of any hyperkalaemia (glucose + insulin + bicarbonate).

Acidosis – monitor patient closely, take corrective action.

Hypocalcaemia – monitor calcium levels, correct as appropriate.

Management of Warfarin reversal

Stop warfarin 
Give Vitamin K (30mcg/Kg) IV, consider higher doses if INR >8

Clotting factor replacement is required when there is active bleeding. 4-Factor Prothrombin Complex Concentrate (PCC / trade name “Beriplex”) replacement therapy gives superior clotting factor replacement compared to FFP.

• Dosage is calculated based on the current INR and patient’s weight. (see table) 
   
  

  INR	Approximate Dose
  2.0 - 3.9	1ml/kg = 25iu/kg
  4.0 - 6.0	1.4ml/kg = 35iu/kg
  >6.0	2 ml/kg = 50iu/kg

                                                             
• Repeat the INR following Beriplex.
• Further doses of Beriplex or Vitamin K may be required.

To order Beriplex discuss with on call Haematologist and request via TrakCare.

It is essential that Blood Bank is informed whenever the clinical emergency has ended to minimise wastage of blood components. This is the responsibility of the clinical lead / nurse coordinator.

• In the event of a pre-hospital ‘code red’ the MH protocol should be triggered by calling 2222 and stating ‘code red major haemorrhage’ and stating location.
• Activation should result in immediate provision of 4 units PRCs and 4 units FFP (pre-thawed) as a pack regardless of age and weight, and a designated porter to transport specimens and blood products to and from the labs.
• The first pack can be issued without forms.
• O neg blood can be obtained directly from RHC theatres fridge if needed but blood bank should be informed it has been removed.
• Following triggering of the major haemorrhage protocol -  blood bank should phone ED to confirm further product requirements.  If not instigated by blood bank then ED team to contact blood bank.  Named contact person and direct dial number should be obtained for blood bank and ED contact person.  Further product requirements and progress of product requests should be communicated between these two representatives.
• Products should be given as per protocol (20ml/Kg PRC/ 20ml/Kg FFP/ 10mls/Kg PLT and 5ml/Kg cryo) - aiming for 1:1:0.5 (PRC/FFP/PLT) ratio. Cryoprecipitate will always take longer to arrive than other products.

Activation of the major haemorrhage response will be audited by the local Hospital Transfusion Committee so that defects in the process can be identified, rectified, and lessons learned fed back to all staff involved in the major haemorrhage response.

NOTES:

• Assess weight of patient
• Platelet availability: a limited stock of platelets are held on-site
• Always remember 'thaw time' for Cryo and additional FFP can be up to 20 mins
• The EZIO drill is a specifically designed intraosseus drill for fluid and blood administration, with sizes appropriate for all ages. It is available in ED and Theatre 6 (84358)
• The laboratory cannot process a marrow sample
• Blood warmer can be obtained from Theatre (ext 84358)
• Blood Bank Major Haemorrhage (ext 82277)
• MLA Blood Runner page 17262
• REMEMBER COMMUNICATION LEAD MUST NOTIFY BLOOD BANK TO 'STAND DOWN' WHEN APPROPRIATE
