Current opinion in critical care

Although detailed practice parameters have been developed to help guide physicians in brain death determination, guidelines based on these parameters widely vary. The recent case of Jahi McMath not only highlights social misconceptions but also serves as a call to action to decrease medical variability and confusion regarding brain death determination. This review discusses common sources of variations in brain death determination - we divide these sources into before, during, and after brain death declaration. ⋯ Diagnosing brain death is confusing because of numerous variations in practice, but this variation can be improved. Improved and standardized physician training can help create a formal certification process for examiners and help create uniformity in brain death determination. National standards will also help decrease variability of practice.

ReviewReversal of the novel oral anticoagulants dabigatran, rivoraxaban, and apixaban.
We summarize the available data related to reversing the anticoagulant effect of the oral direct thrombin and factor Xa inhibitors and provide our opinion on treating patients presenting with severe and life-threatening hemorrhage related to these agents. ⋯ In the absence of evidence in bleeding patients, animal models and ex-vivo studies suggest administration of coagulant factors in the form of hemostatic agents may be of benefit in reversing the effect of direct thrombin and factor Xa inhibitors. Specific reversal agents and clinical data in patients with hemorrhage remain an unmet need.

ReviewRecommendations for the use of multimodal monitoring in the neurointensive care unit.
Multimodal monitoring (MMM) is routinely applied in neurointensive care. Unfortunately, there is no robust evidence on which MMM-derived physiologic variables are the most clinically relevant, how and when they should be monitored, and whether MMM impacts outcome. The complexity is even higher because once the data are continuously collected, interpretation and integration of these complex physiologic events into targeted individualized care is still embryonic. ⋯ MMM allows comprehensive exploration of the complex pathophysiology of acute brain damage and, depending on the different configuration of the pathological condition we are treating, the application of targeted individualized care. Unfortunately, we still lack robust evidence on how to better integrate MMM-derived information at the bedside to improve patient management. Advanced informatics is promising and may provide us a supportive tool to interpret physiologic events and guide pathophysiological-based therapeutic decisions.

ReviewBlood pressure management in acute intracerebral hemorrhage: current evidence and ongoing controversies.
Spontaneous intracerebral hemorrhage (ICH) is associated with high rates of morbidity and mortality. Although treatment options are limited, a potential acute medical intervention is blood pressure (BP) reduction. The review will summarize the current evidence and remaining knowledge gaps with respect to acute BP management in acute ICH. ⋯ Recent trials have shown that BP lowering (<140 mmHg systolic) is well tolerated and may improve functional outcomes. Ongoing trials will provide insight into the overall benefit of early aggressive BP reduction in acute ICH.
