Neuro trials

 

HACA 2000

Question

Deliberate hypothermia after OOHVFA

Type

·      Multi-centre, partially-blinded RCT

Groups

·      32-34°C vs normothermia for 24 hours

Upshot

·      ↓Mortality in hypothermic group

Comments

·      Control group became hyperthermic

·      Did cold group do better because cold, or because not hot?

 

ISAT 2002

Question

Coiling vs clipping for SAH

Type

·      Multi-national RCT

Upshot (coiling)

·      ↓Mortality at 1 year

·      ↑Further bleeding but still unlikely

 

CRASH 2004

Question

IV corticosteroid in TBI

Type

·      Multi-national, placebo-controlled RCT

Upshot

·      ↑2/52 mortality

·      ↑6/12 mortality

 

iHAST 2005

Question

Deliberate intra-op hypothermia (33C) for intracranial aneurysm surgery

Type

·      Multi-centre, partially blinded RCT

Groups

·      33°C vs 36.5°C

Upshot (cold)

·      ↑Post-op bacteraemia

·      ↔Neuro outcome

 

HHH systematic review 2010

Question

Triple H therapy in SAH

Upshot

·      Evidence for hypertension

·      No evidence for hypervolaemia or haemodilution

 

DECRA 2011

Question

Decompressive craniectomy in TBI

Type

·      Multi-centre RCT

Upshot

·      ↓ICP

·      ↓ICU length of stay

·      ↑Unfavourable outcome

 

COOLKIDS 2013

Question

Deliberate hypothermia after TBI in paeds

Upshot

·      Terminated early because waste of time

 

TTM 2013

Question

Deliberate hypothermia after cardiac arrest

Type

·      Multi-national RCT

Groups

·      33°C vs 36°C

Upshot

·      Constant temp preferable

·      No evidence for benefit of cooling

 

RESCUEicp 2016

Question

Decompressive craniectomy for traumatic intracranial hypertension

Type

·      Multi-national RCT

Upshot

·      ↓Mortality

·      ↑Severe disability

 

POLAR 2018

Question

Deliberate hypothermia after blunt TBI

Type

·      Multi-national, partially blinded RCT

Groups

·      33°C vs 37°C

Upshot

·      ↔Neuro outcome at 6 months

·      ↔ICP

·      ↑Pneumonia

·      ↑Ventilation days

·      ↑Bradycardia

·      ↑Noradrenaline use

·      Comment: lays to rest the question of therapeutic hypothermia

 

CRASH-3 2019

Question

TXA in TBI

Type

Multi-national, double-blinded placebo-controlled RCT

Upshot

Mortality
