Review Meta Analysis
The experiences of cardiac arrest survivors and their key supporters following cardiac arrest: a systematic review and meta-ethnography.
To review qualitative studies on the experience of sudden cardiac arrest survival from the perspective of both survivors and their key supporters, including family/close friends. ⋯ The enduring psychosocial and physical sequelae of cardiac arrest survival substantially impacts the lives of survivors and their key supporters, requiring negotiation of their 'new normality'. The need for sense-making, physical and psychological recovery, and the new roles for key supporters should be strong considerations in the development of future interventions.

Estimates of the prevalence of drug-related out of hospital cardiac arrest (OHCA) vary, ranging from 1.8% to 10.0% of medical OHCA. However, studies conducted prior to the recent wave of fentanyl deaths likely underestimate the current prevalence of drug-related OHCA. We evaluated recent trends in drug-related OHCA, hypothesizing that the proportion of presumed drug-related OHCA treated by emergency medical services (EMS) has increased since 2015. ⋯ Drug-related OHCA is an increasingly common etiology of OHCA. In 2023, one in six OHCA was presumed to be drug related. Among participants less than 60 years old, one in three OHCA was presumed to be drug related.

Randomized Controlled Trial
Thiamine as a Metabolic Resuscitator after Out-of-hospital Cardiac Arrest.
Thiamine is a key cofactor for aerobic metabolism, previously shown to improve mortality and neurological outcomes in a mouse model of cardiac arrest. We hypothesized that thiamine would decrease lactate and improve outcomes in post-arrest patients. ⋯ In this single-center randomized trial, thiamine did not affect lactate over 24 hours after OHCA.

In case of out-of-hospital cardiac arrest (OHCA) personnel of the emergency medical services (EMS) are regularly confronted with advanced directives (AD) and do-not-attempt-resuscitation (DNACPR) orders. The authors conducted a retrospective analysis of EMS operation protocols to examine the prevalence of DNACPR in case of OHCA and the influence of a presented DNACPR on CPR-duration, performed Advanced-Life-Support (ALS) measures and decision making. ⋯ In case of CPR EMS-personnel are often confronted with DNACPR-orders. Patients are older and have more previous diseases than patients without DNACPR. Initiated layperson-CPR might lead to misinterpretation of patients will with impact on CPR-duration and unwanted measures. Awareness of this issue should be created through measures such as training programs in particular to train staff in the interpretation and legal admissibility of ADs.

Multicenter Study Comparative Study
A retrospective, multi-agency 'target trial emulation' for the comparison of post-resuscitation epinephrine to norepinephrine.
Epinephrine and norepinephrine are the two most commonly used prehospital vasopressors in the United States. Prior studies have suggested that use of a post-ROSC epinephrine infusion may be associated with increased rearrest and mortality in comparison to use of norepinephrine. We used target trial emulation methodology to compare the rates of rearrest and mortality between the groups of OHCA patients receiving these vasopressors in the prehospital setting. ⋯ In this multi-agency target trial emulation, the use of a post-resuscitation epinephrine infusion was not associated with increased odds of rearrest in comparison to the use of a norepinephrine infusion.
