Despite recent management improvement, including Extracorporeal Life Support (ECLS), refractory out of hospital cardiac arrest (ROHCA) survival remains dramatically low. ⋯ The use of a new paradigm of ROHCA dramatically shortened the time to ECLS initiation by reducing the time spent on site by more than 20 min. Survival improved from 7% to 25% after implementation of OSCAR-ECLS.

Patients in the intensive care unit (ICU) who develop chronic critical illness significantly stress the clinical capacity and financial resources of healthcare systems. Although vast improvements have been made in critical care management, outcomes for this ICU subset remain poor. A hallmark for patients who progress to chronic critical illness is the development of persistent inflammation and immunosuppression. ⋯ Interestingly, each of these clinical states bears strikingly similar immune defects, often resulting in the activation of a persistent inflammatory state. Strategies aimed at the prevention or early recognition of this state of immune compromise may help improve outcomes for these individuals and minimize the number who progress to chronic critical illness. This review explores the current knowledge regarding the immune defects associated with the development of persistent inflammation, the ways in which it can manifest clinically, attempted therapeutic interventions to date, and future insights into improving outcomes for this patient population.

Far from traditional "vital signs," the field of hemodynamic monitoring (HM) is rapidly developing. However, it is also easy to misunderstand hemodynamic therapy as merely HM and some concrete bundles or guidelines for circulation support. Here, we describe the concept of "critical hemodynamic therapy" and clarify the concepts of the "therapeutic target" and "therapeutic endpoint" in clinical practice. ⋯ The flow-directed target for fluid infusion might be a priority, but it remains controversial in resuscitation. The interpretation of these targets is necessary for adequate resuscitation and the correction of tissue hypoxia. The incoherence phenomenon of resuscitation (macrocirculation and microcirculation, tissue perfusion, and cellular oxygen utilization) is gaining increased attention, and early identification of these incoherences might be helpful to reduce the risk of over-resuscitation.

The release of damage-associated molecular pattern molecules in the extracellular space secondary to injury has been shown to cause systemic activation of the coagulation system and endothelial cell damage. We hypothesized that pediatric trauma patients with increased levels of histone-complexed DNA fragments (hcDNA) would have evidence of coagulopathy and endothelial damage that would be associated with poor outcomes. ⋯ hcDNA is released following injury and correlates with coagulopathy, endothelial glycocalyx damage, and poor clinical outcome early after severe pediatric trauma. These results indicate that hcDNA may play an important role in development of coagulation abnormalities and endothelial glycocalyx damage in children following trauma.

This study was conducted to assess the prognostic value of a simplified mortality score (SMS) using the delta neutrophil index (DNI) and thrombotic microangiopathy (TMA) score, both easily obtained from the complete blood count, to identify critically ill patients at high risk of death. ⋯ The SMS is a more rapid, simple prognostic score for predicting 28-day mortality and stratifying risk than the APACHE II or SOFA scores. However, external validation using a larger sample is needed.
