Deans' stroke musings: EXPRESS: Therapeutic Hypothermia for Intracerebral Hemorrhage: Systematic Review and Meta-Analysis of the Experimental and Clinical Literature

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

EXPRESS: Therapeutic Hypothermia for Intracerebral Hemorrhage: Systematic Review and Meta-Analysis of the Experimental and Clinical Literature

So not enough evidence yet. Will your stroke doctors and hospital be competent enough to get research going that definitely answers the question?

Abstract

Background

Intracerebral hemorrhage (ICH) remains the deadliest form of stroke worldwide, inducing neuronal death through a wide variety of pathways. Therapeutic hypothermia (TH) is a robust and well studied neuroprotectant widely used across a variety of specialties.

Aims

This review summarizes results from preclinical and clinical studies to highlight the overall effectiveness of TH to improve long-term ICH outcomes while also elucidating optimal protocol regimens to maximize therapeutic effect.

Summary of Review

A systematic review was conducted across three databases to identify trials investigating the use of TH to treat ICH. A random-effects meta-analysis was conducted on preclinical studies, looking at neurobehavioral outcomes, blood brain barrier breakdown (BBB), cerebral edema, hematoma volume, and tissue loss. Several mixed-methods meta-regression models were also performed to adjust for variance and variations in hypothermia induction procedures. 21 preclinical studies and 5 human studies were identified. The meta-analysis of preclinical studies demonstrated a significant benefit in behavioral scores (ES=-0.43, p=0.02), cerebral edema (ES=1.32, p=0.0001), and BBB (ES=2.73, p=<0.00001). TH was not found to significantly affect hematoma expansion (ES=-0.24, p=0.12) or tissue loss (ES=0.06, p=0.68). Clinical study outcome reporting was heterogeneous, however there was recurring evidence of TH-induced edema reduction.

Conclusions

The combined preclinical evidence demonstrates that TH reduced multiple cell death mechanisms initiated by ICH, yet there is no definitive evidence in clinical studies. The cooling strategies employed in both preclinical and clinical studies were highly diverse, and focused refinement of cooling protocols should be developed in future preclinical studies. The current data for TH in ICH remains questionable despite the highly promising indications in preclinical studies. Definitive randomized controlled studies are still required to answer this therapeutic question.
