Meta Analysis
Drug therapy versus placebo or usual care for comatose survivors of cardiac arrest; a systematic review with meta-analysis.
In Europe, approximately 291,000 cardiac arrests occur annually. Despite critical care therapy, hospital mortality remains high. This systematic review assessed whether, in comatose survivors of cardiac arrest, any drug therapy, compared to placebo or usual care, improves outcomes. ⋯ In comatose survivors of cardiac arrest, the majority of trials of drug therapy reported no effect on mortality. Meta-analyses of steroids, coenzyme Q10 and thiamine demonstrated no evidence of an effect on mortality. However, the low certainty of evidence warrants further research.

Randomized Controlled Trial
Interleukin 6 blockage alters the plasma metabolome in out-of-hospital cardiac arrest.
Comatose patients resuscitated from out-of-hospital cardiac arrest (OHCA) exhibit a systemic inflammatory response, as indicated by elevated interleukin-6 (IL-6) levels, which is associated with increased mortality. Tocilizumab, an IL-6 receptor antagonist that reduced C-reactive protein response and markers of myocardial injury in a phase II OHCA trial. ⋯ Blocking the IL-6 receptor with tocilizumab early after OHCA impacts circulating metabolites, particularly those within the glycine, serine, and threonine pathways, highlighting the connection between acute systemic inflammation and metabolism. Further, early levels of TCA metabolites are independently associated with early inflammatory response and early medium-chain acylcarnitine with later markers of neurological injury.

Dispatcher-assisted cardiopulmonary resuscitation (DACPR) significantly improves the survival of out-of-hospital cardiac arrest (OHCA) patients. However, the effectiveness of DACPR may vary depending on the location of the cardiac arrest. This study compares DACPR outcomes in private homes versus public places. ⋯ This study demonstrated reduced DACPR effectiveness in public places compared to private homes, potentially influenced by caller factors, environmental conditions, and the caller-patient relationship. Developing location-specific strategies is essential to enhance DACPR effectiveness.

This is the eighth annual summary of the International Liaison Committee on Resuscitation International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations; a more comprehensive review was done in 2020. This latest summary addresses the most recent published resuscitation evidence reviewed by the International Liaison Committee on Resuscitation task force science experts. ⋯ Insights into the deliberations of the task forces are provided in the Justification and Evidence-to-Decision Framework Highlights sections. In addition, the task forces list priority knowledge gaps for further research.
