Targeted temperature management (TTM) as a neuroptotective strategy is applied in a number of scenarios; post-ROSC in cardiac arrest, neonatal asphyxia, traumatic brain injury, to name some. The Neurocritical Care Society have taken it upon themselves to formulate an evidence-based guideline to the implementation and practical management of TTM in a number of settings. Although… Continue reading TTM – New Guidelines from NCS
Results from the HYBERNATUS trial were just published in the New England Journal of Medicine by Legriel et al. This study recruited 270 patients with convulsive status epilepticus, randomized to either therapeutic hypothermia (32-34 C) or normothermia. All patients were intubated and on controlled ventilation when included. All received standard antiepileptic pharmacological treatment. Primary outcome… Continue reading HYBERNATUS Trial: Hypothermia Not Associated With Better Outcomes in Status Epilepticus
The long-awaited Eurotherm trial was published in NEJM in autumn 2015. The premise of the study was to examine the impact of induced hypothermia on outcomes after traumatic brain injury. In a multi center randomized controlled trial patients were allocated to either therapeutic hypothermia (32-35 degrees) or the control group (standard care, normothermia). The study… Continue reading Eurotherm 3235 Trial
Excellent talk by Manoj Saxena on traumatic brain injury and temperature control. A useful overview of the available evidence. From SMACC Chicago 2015.
Just off the press: Cochrane Collaboration Review of the use of therapeutic hypothermia after cardiopulmonary resuscitation. “Evidence of moderate quality suggests that conventional cooling methods provided to induce mild therapeutic hypothermia improve neurological outcome after cardiac arrest, specifically with better outcomes than occur with no temperature management” The updated Cochrane review goes a long way… Continue reading Cochrane Review – Hypothermia for Neuroprotection after Cardiac Arrest
