Review Meta Analysis
Targeted Temperature Management in Adult Cardiac Arrest: Systematic Review and Meta-Analysis.
To perform a systematic review and meta-analysis on targeted temperature management in adult cardiac arrest patients. ⋯ Among adult patients with cardiac arrest, the use of targeted temperature management at 32-34 °C, when compared to normothermia, did not result in improved outcomes in this meta-analysis. There was no effect of initiating targeted temperature management prior to hospital arrival. These findings warrant an update of international cardiac arrest guidelines.

Point-of-care ultrasound (POCUS) has been shown to assist in predicting outcomes in cardiac arrest. We evaluated the test characteristics of POCUS in predicting poor outcomes: failure of return of spontaneous circulation (ROSC), survival to hospital admission (SHA), survival to hospital discharge (SHD) and neurologically intact survival to hospital discharge (NISHD) in adult and paediatric patients with blunt and penetrating traumatic cardiac arrest (TCA) in out-of-hospital or emergency department settings. ⋯ Patients in TCA without cardiac activity on POCUS have a high likelihood of death and negligible chance of SHD. The numbers of patients included in published studies remains too low for practice recommendations for termination of resuscitation based solely upon the absence of cardiac activity on POCUS.

To evaluate the relationship between the accessibility of automatic external defibrillators (AEDs) and the survival rate of patients who have out-of-hospital cardiac arrest (OHCA). ⋯ The improvement of accessibility of AEDs may increase the survival rate of OHCA and the survival rate may be higher in playgrounds, airports, and schools equipped with AEDs. However, the strength of evidence was limited by the considerably heterogeneity of included studies. Verification of these findings in further studies is warranted.

Advances in resuscitation following out-of-hospital cardiac arrest (OHCA) provide an opportunity to improve public health. This review reflects on past developments, present status, and future possibilities using the science-education-implementation framework of the Utstein Formula and the clinical framework of the links in the chain of survival. With the discovery of CPR and defibrillation in the mid 20th century, resuscitation developed a scientific construct for progress. ⋯ For many systems, telecommunicator CPR and high-performance CPR by emergency professionals are accessible, near-term programs to improve OHCA outcome. Smart technologies that activate, coordinate, and/or coach community "volunteers" to accelerate early CPR and defibrillation have conceptual promise, though robust implementation has been achieved by only a handful of systems. Longer-term strategies may leverage technology to develop a high-fidelity "life-detector" or engineer and disseminate a specialized consumer defibrillator designed to bridge care until arrival of professional response.

Review Meta Analysis
Mortality after In-Hospital Cardiac Arrest in Patients with COVID-19: A Systematic Review and Meta-Analysis.
To estimate the mortality rate, the rate of return of spontaneous circulation (ROSC) and survival with favorable neurological outcome in patients with COVID-19 after in-hospital cardiac arrest (IHCA) and attempted cardiopulmonary resuscitation (CPR). ⋯ Although one of three COVID-19 patients undergoing IHCA may achieve ROSC, almost 90% may not survive at 30 days or to hospital discharge.
