Coma/Anoxic Brain Injury

Levy DE, Caronna JJ, Singer BH, et al. Predicting outcome from hypoxic-ischemic coma. JAMA 1985;253:1420-6. The relevance of the prognostic predictors determined by physical examination in this landmark study may be less certain in the era of therapeutic hypothermia.

Coplin WM, Pierson DJ, Cooley KD, et al. Implications of extubation delay in brain-injured patients meeting standard weaning criteria. Am J Respir Crit Care Med 2000;161:1530-6. Prospective cohort study found patients with "delayed" extubation had increased incidence of nosocomial pneumonia, longer ICU and hospital stays, and greater hospital charges.

Therapeutic hypothermia following cardiac arrest

The following simultaneously-published studies found reducing core body temperature to 32°C to 34°C for 12 or 24 hours improved neurologic outcomes in comatose survivors of out-of-hospital cardiac arrest with an initial shockable rhythm:

Nielsen N, Wettersley J, Cronberg T, et al. Targeted temperature management at 33°C versus 36°C after cardiac arrest. N Engl J Med. 2013;369:2197-206. This larger RCT of 950 patients with out-of-hospital cardiac arrest found that patients who survived an out of hospital cardiac arrest but remained unconscious had similar outcomes whether temperature was targeted for 33oC or 36oC.

Jabre P, Bougouin W, Dumas F, et al. Early identification of patients with out-of-hospital cardiac arrest with no chance of survival and consideration for organ donation. Ann Intern Med. 2016; 165:770-8. The benefits of therapeutic hypothermia were demonstrated in patients presenting with a shockable rhythm, but aggressive resuscitation and cooling are recommended for patients with out-of-hospital cardiac arrest (OHCA) regardless of presenting rhythm. This retrospective analysis of a French registry from 2011 to 2014 found no survivors to hospital discharge among 772 patients who met all of the following 3 criteria: 1) OHCA not witnessed by medics, 2) non-shockable initial cardiac rhythm, and 3) no ROSC prior to receipt of a 3rd 1-mg dose of epinephrine. Validation in an additional 2,000 patients who met these criteria from other registries and trials found 1 survivor, in a persistent vegetative state.

Guidelines for the management of spontaneous intracerebral hemorrhage: a guideline for healthcare professionals from the American Heart Association/American Stroke Association. Stroke 2010; 41:2108-29. Guidelines offer primarily expert-opinion based recommendations and acknowledge the lack of available evidence to guide medical management. Published prior to more recent studies showing recombinant factor VII does not improve clinical outcomes.

Powers WJ, Derdeyn CP, Biller J, et al. 2015 American Heart Association/American Stroke Association Focused Update of the 2013 Guidelines For The Early Management Of Patients With Acute Ischemic Stroke Regarding Endovascular Treatment: A Guideline for Healthcare Professionals From the American Heart Association/American Stroke Association. Stroke. 2015; 46:3020-3035. This focused update highlights recent evidence on endovascular treatment. Emergent non-enhanced CT imaging is affirmed, but if endovascular therapy is contemplated, a noninvasive intracranial vascular study is strongly recommended during initial imaging if it will not delay intravenous r-tPA. It also recommends that patients eligible for intravenous r-tPA receive it even if endovascular treatments are being considered.  Endovascular interventions that may benefit patients in the 4.5 to 6 hour window are also addressed.

Qureshi A, Palesch Y, Barsan W, et al. Intensive blood-pressure lowering in patients with acute cerebral hemorrhage. N Engl J Med. 2016;375:1033-43. A randomized open label trial of aggressive (110-139 mmHg) versus standard (140-179 mmHg) BP management of patients with spontaneous supratentorial cerebral hemorrhage within 4.5 hours of onset. This is a response to the INTERACT2 trial, which initiated treatment within 6 hours of onset. The mean SBP at 2 hours was 128 mm Hg in the aggressive group and 141 mmHg in the standard group. There were no differences in death or disability at 3 months, and the rate of renal adverse events within 7 days of randomization were higher in the aggressive control group.

DeGans J, van de Beek D. Dexamethasone in adults with bacterial meningitis. N Engl J Med 2002; 347:1549-56. High quality RCT including 301 patients found early administration of 10 mg dexamethasone q 6 hrs for 4 days reduced the risk of poor outcome (score of 5 vs. score of 1-4 on Glasgow Outcome Scale) [relative risk 0.59] and was associated with a relative risk of death of 0.48. Subgroup analysis showed that the outcome improvement was restricted to patients with pneumococcal meningitis.
