The aim of this study was to illustrate the varying roles of echocardiography in all phases of shock ranging from a rapid, diagnostic tool at the bedside, to a tool for monitoring the adequacy and effects of shock treatment and finally for identification of patients suitable for de-escalation of therapy. ⋯ This study provides the reader with a structured review on the uses of echocardiography in all phases of shock treatment.

The ANDROMEDA-SHOCK trial positioned capillary refill time (CRT) assessment as a novel resuscitation target for septic shock.The purpose of this article is to summarize pathophysiological determinants of CRT, review new technical developments on peripheral perfusion assessment, and explore recent evidence on the role of CRT monitoring in septic shock and other critical conditions. ⋯ Recent data confirm the relevance of peripheral perfusion assessment in septic shock and other conditions in critically ill patients. Future studies should confirm these findings, and test the potential contribution of technological devices to assess peripheral perfusion.

ReviewThe role of the electroencephalogram and evoked potentials after cardiac arrest.
In comatose cardiac arrest survivors, the electroencephalogram (EEG) is the most widely used test to assess the severity of hypoxic-ischemic brain injury (HIBI) and guide antiseizure treatment. However, a wide variety of EEG patterns are described in literature. Moreover, the value of postarrest seizure treatment is uncertain. Absent N20 waves of short-latency somatosensory-evoked potentials (SSEPs) are a specific predictor of irreversible HIBI. However, the prognostic significance of the N20 amplitude is less known. ⋯ Standardized EEG terminology and quantitative approach to SSEP are promising for improving the neuroprognostic accuracy of these tests. Further research is needed to identify the potential benefits of antiseizure treatment after cardiac arrest.

The purpose of this review was to provide an overview of head-up (HUP) CPR physiology, relevant preclinical findings, and recent clinical literature. ⋯ HUP CPR is a new and novel therapy increasingly used in the prehospital setting and discussed in the resuscitation community. This review provides a relevant review of HUP CPR physiology and preclinical work, and recent clinical findings. Further clinical studies are needed to further explore the potential of HUP CPR.
