Excellent review of asssessment of cerebral circulation by Donnelly et al. in Critical Care May 2016. The authors go through most of today’s available modalities and review their utility in neurocritical care. Find the article here.
It is widely accepted that hypotension in patients with traumatic brain injury is associated with poorer outcomes, as confirmed in a number of studies. But is there really a reliable cut-off for when we should be happy with a TBI patient´s blood pressure in a prehospital setting? A recent article in JAMA Surgery (Spaite et… Continue reading Prehospital BP and Mortality in TBI: Time to Reevaluate Our Haemodynamic Targets?
Published in 2011 by Schmidt et al (free full-text in Stroke), this article looks at CPP thresholds for cerebral hypoxia in SAH patients. They went through multimodal monitoring data for 30 patients with poor-grade SAH. Using microdialysis and brain tissue oxygenation as their main determinants of hypoxia, they found that patients with a CPP <70… Continue reading Cerebral Perfusion Pressure Thresholds for Brain Tissue Hypoxia and Metabolic Crisis After Poor-Grade Subarachnoid Hemorrhage
Published in NEJM 2016, the Antihypertensive Treatment of Acute Cerebral Hemorrhage II (ATACH-II) trial compared two BP-management regimes in intracerebral haemorrhage patients with hypertension (SBP>180 mmHg): Intensive lowering to SBP 110-139 mm Hg. vs. standard treatment to within the 140-179 mm Hg range. The trial was discontinued early after an interim analysis showed no difference between the groups in… Continue reading ATACH II Trial – No Benefit From Aggressive BP-lowering in ICH
Right off the press: an open access review article from Critical Care on fluid therapy in the neurological patient. It provides a nice synopsis of the different fluid therapy paradigms that are advocated through various guidelines. The review challenges some of the tenets of basic treatment, such as empirical fluid maintenance and the definition of… Continue reading Critical Care: Fluid Therapy in Neurological Patients
A quick review published in BMJ´s Best Evidence Topic Reports series, April 2016 by Kapil Mohan Rajwani and Azlisham Mohd Nor. They address the issue of lowering elevated blood pressures in patients with an acute ICH. Is it safe and is there evidence to support active BP-management? And if yes, what´s our target? Targeted blood pressure management in… Continue reading Best BETs – Safe to Lower BP in ICH?
