Transfusion trials

 

TRICC 1999

Hb 7-9 vs 10-12: in ICU

Type: multi-centre RCT

-↓Mortality in restrictive group

-Doesn’t apply if active myocardial ischaemia

FOCUS 2011

Hb 8 vs 10: hip fracture

Type: multi-centre RCT

-↔Mortality

-Functional outcome

TRISS 2014

Hb 7 vs 9: septic shock

Type: multi-centre RCT

-↔Mortality in restrictive group

-↔Ischaemic events

Villaneuva 2013

Hb 7 vs 9: upper GI bleeding

Type: single-centre RCT

-↓Mortality in restrictive group

PROMMTT 2013

Ratios of RBC:FFP:plt – balanced vs RBC-heavy

Type: prospective cohort study

Upshot:

 <6 hours: ↓↓mortality if balanced

 >24 hours: no difference

PROPPR 2015

Ratios of RBC:FFP:plt in trauma – 2:1:1 vs 1:1:1

Type: multi-centre RCT

Upshot of 1-1-1:

↔Mortality (but underpowered for this)

↓Time to haemostasis

↓Death due to exsanguination

TITRe2 2015

Hb 7.5 vs 9: elective cardiac surgery

Type: multi-centre RCT

Upshot of restrictive:

-↑Mortality (reason unclear)

-Ischaemic events

TRICS-3 2018

Hb 7.9 vs 9.5: high risk cardiac surgery

Type: multi-national RCT

Subjects: EuroSCORE 6

Upshot: no difference in disasters (composite death/AMI/dialysis)
