Monitoring of the peripheral circulation can be done noninvasively in contrast to the more traditional invasive systemic haemodynamic monitoring in the intensive care unit. Physical examination of peripheral circulation based on clinical assessment has been well emphasized for its convenience, accessibility, and relation to the prognosis of patients with circulatory shock. The purpose of this article is to highlight the main findings according to recent literature into the clinical applications of the peripheral perfusion assessment in patient management. ⋯ The feasibility and reproducibility of the clinical assessment of peripheral circulation are substantial, and reliance on capillary refill time, skin temperature, and mottling score must be emphasized and exploited. Incorporating therapeutic strategies into resuscitation protocols that aim at normalizing these peripheral circulation parameters are being developed to investigate the impact of peripheral perfusion-targeted resuscitation in the survival of critically ill patients.

Diagnosis of acute mesenteric ischemia in the early stages is now possible with modern computed tomography (CT), using intravenous contrast enhancement and imaging in the arterial and/or portal venous phase. The availability of CT around the clock means that more patients with acute mesenteric ischemia may be treated with urgent intestinal revascularization. ⋯ Intestinal revascularization in patients with arterial occlusive mesenteric ischemia reduces bowel morbidity and mortality. Observational studies report that both endovascular and open vascular therapy options are effective, but endovascular technique may be preferred in these often elderly and fragile patients.

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.

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.
