Major Haemorrhage Policy for Trauma Rachel Hawes RVI Northern trauma network conference March 2014
Background • Leading cause of traumatic death • Advances in haemostatic resuscitation • Balanced transfusion 1:1:1:1 • Introduction of MHP • Questions • How many major haemorrhage pt? • Frequency of Acute Coagulopathy of Trauma (ACoT) • How effective is our MHP?
RVI Major Haemorrhage Policy • Standardise blood product use • Reduce logistical delay • Prehospital initiation • Pre-thawed FFP • avoid delay in receiving balanced transfusion
Audit • Inclusions • All trauma patients to RVI • April 2012 - April 2013 • >18 yrs • Activation of MHP • Or >4 products in 1 hr • Exclusions • Children • Preceding medical event • Transfers via Trauma Units • Data Collection • Injury Severity Score (ISS) • TARN Predicted Survival • Actual 30 day mortality • Presentation - Hb, PT, Fib • Products Transfused • Post MHP - Hb, PT, Fib
Results - How much trauma do we get? • April 2012 - April 2013 • 935 trauma calls • 899 TARN patients • RTA • Assault • Fall • Frequent of major haemorrhage? • 51 MHP Patients (5.6%)
ACoT on Presentation in ED? Fibrinogen on presentation Fibrinogen <1.5 = 21% PT on presentation PT> 18 = 16%
Is ACoT due to Prehospital Fluid? • No correlation between fluid volumes given and • Hb on presentation • PT on presentation • Fib on presentation
Presence of Coagulopathy Post MHP • Post MHP Fib <1.5 = 0% • (Data for 33 Pt) • Post MHP PT > 18 = 3% • (Data for 29 Pt)
Hb on Arrival v Post MHP • Hb on arrival <8.0 = 6.8% • Over and under transfusion • Hb post MTP <8.0 = 5.8%
The Future • Over and under transfusion • Deviation from policy • Timing of lab results • Lack of Point of Care testing - guide treatment • Potential role of ROTEM/ TEG • Prehospital Transfusion
Limitations • Early deaths after presentation • Unable to get bloods • Included in ISS calculations but excluded for comparison of lab data
Summary • Trauma - Mortality proportional to ISS • 5% of patients have major haemorrhage • Increased mortality ass with major haemorrhage • 20% established ACoT on arrival • Not related to prehospital fluid administration • MHP effective in treatment and prevention of ACoT • Future • POCT – TEG or ROTEM • ‘Blood on Board’ HEMS
