Cardiac arrest patients presenting with non-shockable rhythms have a low probability of survival, and epinephrine is one of the few pharmaceutical options for this group. The recommended 1.0 mg adult dose is extrapolated from early animal studies and lacks adjustment for patient weight. Although several prior studies have investigated "low-" and "high-" dose epinephrine, none have identified a benefit to either strategy. ⋯ Among patients with a low likelihood of survival, the optimal dose of epinephrine for attaining ROSC with a single bolus of epinephrine was 0.013 mg/kg. These findings should inspire further investigation into optimal dosing strategies for epinephrine.

ReviewModernization of Cardiac Advanced Life Support: Role and Value of Cardiothoracic Anesthesiologist Intensivist in Post-Cardiac Surgery Arrest Resuscitation.
Cardiac arrest in the postoperative cardiac surgery patient requires a unique set of management skills that deviates from traditional cardiopulmonary resuscitation and Advanced Cardiovascular Life Support (ACLS). Cardiac Advanced Life Support (CALS) was first proposed in 2005 to address these intricacies. The hallmark of CALS is early chest reopening and internal cardiac massage within 5 minutes of the cardiac arrest in patients unresponsive to basic life support. ⋯ As such, we have proposed a modified CALS approach to (1) adapt to a newer generation of cardiac surgery patients and (2) incorporate advanced resuscitative techniques. These include rescue-focused cardiac ultrasound to aid in the early identification of underlying pathology and guide resuscitation and early institution of extracorporeal cardiopulmonary resuscitation instead of chest reopening. While these therapies are not immediately available in all cardiac surgery centers, we hope this creates a framework to revise guidelines to include these recommendations to improve outcomes and how cardiac anesthesiologist intensivists' evolving role can aid resuscitation.

ReviewReview article: Back to life from being declared dead in the Resus Bay: An integrative review of the phenomenon of autoresuscitation and learning for ED.
This is a literature review of ED autoresuscitation. The impetus for this review was a case which revealed a lack of understanding about Lazarus syndrome among ED staff. The primary objective was to see the proportion of cases who survived neurologically intact to discharge and the time frame when this occurred after death had been declared. ⋯ Under-reporting of autoresuscitation is suspected because of fears of blame. Passive monitoring for 10 min after resuscitation is ceased, is recommended. There is need for more data on this phenomenon to help inform further research on the topic.

Lung parenchymal and pleural findings on computed tomography after out-of-hospital cardiac arrest.
Lung injury and the acute respiratory distress syndrome (ARDS) are common after out-of-hospital cardiac arrest (OHCA), but the imaging characteristics of lung parenchymal and pleural abnormalities in these patients have not been well-characterized. We aimed to describe the incidence of lung parenchymal and pleural findings among patients who had return of spontaneous circulation (ROSC) and who underwent computed tomography (CT) of the chest after OHCA. ⋯ Over three-quarters of patients who survived to the hospital post OHCA and received a chest CT had lung parenchymal or pleural abnormalities, the most common of which were aspiration, pulmonary edema, and consolidation/pneumonia. Future planned research will characterize the clinical impact of these findings and whether early chest CT could identify patients at risk for ARDS or other pulmonary complications.

ReviewRe-evaluating intra-cardiac arrest adjunctive medications and routes of drug administration.
This narrative review summarizes the evidence for the most commonly used intra-cardiac arrest adjunctive medications and routes of administration and discusses promising new therapies from preclinical animal models. ⋯ Large trials on intra-cardiac arrest administration of calcium and vasopressin with glucocorticoids have been performed. Several trials are ongoing that will provide valuable insights into the potential benefit of other intra-cardiac arrest medications such as bicarbonate as well as the potential benefit of intravenous or intraosseous vascular access.
