Incidence, outcomes, and temporal trends of pediatric in-hospital cardiac arrest in Japan: a nationwide study

Jul 27, 2026

The authors aimed to investigate the incidence, outcomes, and temporal trends of pediatric in-hospital cardiac arrest (IHCA) in Japan using a nationwide administrative database from 2011 to 2022. They found a declining incidence of IHCA, from 1.03 to 0.86 per 1,000 admissions, and an improvement in survival rates to hospital discharge, increasing from 25.8% to 30.6% over the study period. The authors emphasize the need for a national registry to validate their findings and enhance understanding of resuscitation practices.

Emergency response with lights and sirens to patients with a suspected out-of-hospital cardiac arrest and a do-not-attempt-resuscitation order in the hospital record: a one-year observational study

Jul 27, 2026

This study investigates the frequency of emergency vehicle dispatches with lights and sirens to patients with suspected out-of-hospital cardiac arrest (OHCA) who have a do-not-attempt-resuscitation (DNAR) order documented in their hospital records. The authors found that 15.7% of dispatches involved patients with a DNAR order, highlighting a significant ethical concern regarding patient autonomy and resource utilization. They advocate for improved accessibility of DNAR orders to prehospital care providers to prevent unnecessary resuscitation attempts.

Association between Preexisting Electrocardiographic Abnormalities and Shockable Initial Rhythm in Out-of-Hospital Cardiac Arrest

Jul 27, 2026

This study investigates the relationship between preexisting electrocardiographic (ECG) abnormalities and the likelihood of a shockable initial rhythm in out-of-hospital cardiac arrest (OHCA). The authors found that specific ECG abnormalities, such as pathological Q-waves and left bundle branch block, were associated with higher odds of a shockable rhythm in bystander-witnessed arrests compared to individuals with normal ECGs. The findings suggest that prior ECGs may provide valuable prognostic information regarding the initial rhythm during OHCA events.

Initial vascular access for neonatal resuscitation: a systematic review

Jul 27, 2026

The authors aimed to evaluate the evidence regarding various emergency vascular access methods used during neonatal resuscitation, particularly focusing on their effectiveness and safety. They found that while umbilical vein catheters (UVC) and intraosseous (IO) devices are feasible options, there is insufficient evidence comparing their outcomes, and most complications were associated with IO devices. The study highlights the need for further research due to the low certainty of the existing evidence and the limitations of the included studies.

Advanced Hemodynamic Monitoring During Post-Resuscitation Care After Out-of-Hospital Cardiac Arrest: A Scoping Review

Jul 23, 2026

The authors aimed to map the available evidence on advanced hemodynamic monitoring practices during early post-resuscitation care after out-of-hospital cardiac arrest (OHCA). They found that while cardiac output and mean arterial pressure were the most commonly monitored variables, the associations between these metrics and clinical outcomes were inconsistent, highlighting the need for future studies to explore integrated approaches and individualized hemodynamic targets.

Associations Between Pulsed Oxygen Saturation During Out-Of-Hospital Cardiopulmonary Resuscitation, Cardiopulmonary Resuscitation Quality and Return Of Spontaneous Circulation

Jul 23, 2026

The authors aimed to investigate the relationship between pulsed oxygen saturation (SpO2) during out-of-hospital cardiac arrest (OHCA) and the likelihood of achieving return of spontaneous circulation (ROSC). They found that higher event-average SpO2 was significantly associated with an increased probability of sustained ROSC and survival to hospital admission, although it did not correlate with neurological intact survival. Additionally, cycle-average SpO2 did not show an association with the quality of chest compressions during CPR.

Racial and Ethnic Differences in Bystander Cardiopulmonary Resuscitation for Opioid-Associated Out-of-Hospital Cardiac Arrests

Jul 23, 2026

This study investigates racial and ethnic disparities in bystander cardiopulmonary resuscitation (bCPR) among adults experiencing opioid-associated out-of-hospital cardiac arrests (OA-OHCA). The authors found that Black and Hispanic patients were significantly less likely to receive bCPR compared to White patients, while no significant differences were observed among other racial groups. The results highlight the need for targeted public health strategies to improve bCPR rates and reduce opioid overdose fatalities across diverse demographic groups.

Where Should We Compress? Ultrasound Identification of the Ideal Area of Maximal Compression for CPR

Jul 23, 2026

The authors aimed to identify the ideal area of maximal compression (iAMC) for CPR in relation to the left ventricular outflow tract (LVOT) and standard chest compression guidelines using transthoracic echocardiography. Their findings indicate that the recommended compression location often aligns more closely with the LVOT than the iAMC, highlighting a potential mismatch between CPR hand placement and optimal ventricular compression. This study suggests a need for reevaluation of CPR techniques to enhance their effectiveness.

One-year liver graft survival from brain-dead donors treated with ECPR for out-of-hospital cardiac arrest

Jul 23, 2026

This study aimed to evaluate the one-year liver graft survival from brain-dead donors who underwent extracorporeal cardiopulmonary resuscitation (ECPR) due to refractory out-of-hospital cardiac arrest (OHCA) compared to a control group of donors not treated with ECPR. The results indicated no statistically significant difference in one-year liver graft survival rates between the two groups, although the ECPR group had a lower organ retrieval rate and younger donors with higher initial severity of illness. The authors caution that the limited sample size means this lack of significance should not be interpreted as evidence of equivalence.

Measurement of tidal volumes and respiratory rate during regular and asynchronous intra-arrest ventilation using the EOlife X device: A method-comparison study in a porcine cardiac arrest model

Jul 23, 2026

The authors aimed to evaluate the accuracy of the EOlife X ventilation feedback device during both regular and intra-arrest ventilation in a porcine cardiac arrest model. They found that while the device performed within clinically acceptable limits during regular ventilation, it significantly deviated from these limits during intra-arrest ventilation, likely due to the effects of chest compressions on airflow measurements. This study highlights the need for specific validation of ventilatory monitoring devices under CPR conditions.
