Randomized Controlled Trial Multicenter Study
Association Between Duration of Resuscitation and Favorable Outcome After Out-of-Hospital Cardiac Arrest: Implications for Prolonging or Terminating Resuscitation.
Little evidence guides the appropriate duration of resuscitation in out-of-hospital cardiac arrest, and case features justifying longer or shorter durations are ill defined. We estimated the impact of resuscitation duration on the probability of favorable functional outcome in out-of-hospital cardiac arrest using a large, multicenter cohort. ⋯ URL: http://clinicaltrials.gov. Unique identifier: NCT00394706.

The appropriate duration of cardiopulmonary resuscitation (CPR) for pediatric out-of-hospital cardiac arrests (OHCAs) remains unclear and may differ based on initial rhythm. We aimed to determine the relationship between the duration of prehospital CPR by emergency medical services (EMS) personnel and post-OHCA outcomes. ⋯ URL: https://clinicaltrials.gov.

Comparative Study
Conventional Versus Compression-Only Versus No-Bystander Cardiopulmonary Resuscitation for Pediatric Out-of-Hospital Cardiac Arrest.
Conventional cardiopulmonary resuscitation (CPR) (chest compression and rescue breathing) has been recommended for pediatric out-of-hospital cardiac arrest (OHCA) because of the asphyxial nature of the majority of pediatric cardiac arrest events. However, the clinical effectiveness of additional rescue breathing (conventional CPR) compared with compression-only CPR in children is uncertain. ⋯ In this population-based study of pediatric OHCA in Japan, both conventional and compression-only CPR were associated with superior outcomes compared with no-bystander CPR. Unadjusted outcomes with conventional CPR were superior to compression-only CPR, with the magnitude of difference attenuated and no longer statistically significant after statistical adjustments. These findings support randomized clinical trials comparing conventional versus compression-only CPR in children, with conventional CPR preferred until such controlled comparative data are available, and either method preferred over no-bystander CPR.

Randomized Controlled Trial Multicenter Study
Neuroprotective Effects of the Glucagon-Like Peptide-1 Analog Exenatide After Out-of-Hospital Cardiac Arrest: A Randomized Controlled Trial.
In-hospital mortality in comatose patients resuscitated from out-of-hospital cardiac arrest (OHCA) is ≈50%. In OHCA patients, the leading cause of death is neurological injury secondary to ischemia and reperfusion. Glucagon-like peptide-1 analogs are approved for type 2 diabetes mellitus; preclinical and clinical data have suggested their organ-protective effects in patients with ischemia and reperfusion injury. The aim of this trial was to investigate the neuroprotective effects of the glucagon-like peptide-1 analog exenatide in resuscitated OHCA patients. ⋯ URL: http://www.clinicaltrials.gov.

Bystander-initiated cardiopulmonary resuscitation (CPR) increases patient survival after out-of-hospital cardiac arrest, but it is unknown to what degree bystander CPR remains positively associated with survival with increasing time to potential defibrillation. The main objective was to examine the association of bystander CPR with survival as time to advanced treatment increases. ⋯ The absolute survival associated with bystander CPR declined rapidly with time. Yet bystander CPR while waiting for an ambulance was associated with a more than doubling of 30-day survival even in case of long ambulance response time. Decreasing ambulance response time by even a few minutes could potentially lead to many additional lives saved every year.
