A randomised controlled trial of defibrillation with manual pressure augmentation during out-of-hospital cardiac arrest

May 7, 2026

The authors aimed to determine whether defibrillation with manual pressure augmentation (MPA) could reduce transthoracic impedance and improve survival rates in patients experiencing out-of-hospital cardiac arrest (OHCA) with a shockable rhythm, compared to standard defibrillation. The study found that while MPA significantly reduced transthoracic impedance, it did not lead to improved survival or other clinical outcomes. The trial was prematurely terminated, and compliance with the MPA intervention was low.

Prediction of Shock-refractory Ventricular Fibrillation in Patients with Out-of-Hospital Cardiac Arrest: External Validation of an ECG-based Approach

May 2, 2026

The authors aimed to externally validate an ECG-based approach for predicting shock-refractory ventricular fibrillation (VF) in patients experiencing out-of-hospital cardiac arrest (OHCA). Using a retrospective cohort from the Seoul OHCA registry, they found that a logistic model incorporating 25 ECG features effectively predicted patients requiring multiple shocks, demonstrating robust performance with area under the curve (AUC) values comparable to those from the original study. This suggests that the ECG feature analysis could be a valuable tool for personalizing resuscitation strategies in this patient population.

Rhythm-specific association of epinephrine with outcomes in non-shockable cardiac arrest: A nationwide propensity-matched study

May 2, 2026

This study aimed to determine how the association between epinephrine administration and return of spontaneous circulation (ROSC) differs between patients with asystole and those with pulseless electrical activity (PEA) during out-of-hospital cardiac arrest. The findings revealed that epinephrine was more strongly associated with ROSC in asystole patients compared to those with PEA shortly after emergency medical service contact, although this difference diminished over time. Additionally, while a similar trend was observed for 30-day survival rates, no significant differences were noted in favorable neurological outcomes between the two groups.

A systematic review of mortality and severe morbidities following newborn chest compressions at birth

May 2, 2026

The authors aimed to synthesize evidence regarding mortality and severe morbidities following delivery room chest compressions (CC) in newborns, examining variations by birth setting, gestation, and level of care. They found significant variability in mortality rates (21-74%) and severe neurological injury (16-42%) among different infant groups, highlighting a lack of consistent definitions and reporting standards across studies. The review emphasizes the need for prospective research to better understand outcomes and improve neonatal resuscitation practices.

The CPR compression matrix: relationship among depth, recoil, and rate

May 2, 2026

The authors aimed to investigate the relationship among compression depth, recoil, and rate during cardiopulmonary resuscitation (CPR) to determine optimal compression performance. Their study found that a compression rate of 100-104 per minute was associated with the highest likelihood of achieving both optimal depth (≥50 mm) and complete recoil, while performance declined at both slower and faster rates. This research highlights the importance of maintaining an appropriate compression rate to enhance CPR effectiveness.

NEUROLOGICAL OUTCOME OF OUT-OF-HOSPITAL CARDIAC ARREST PATIENTS VENTILATED WITH CONTINUOUS FLOW INSUFFLATION OF OXYGEN: A MULTICENTER OBSERVATIONAL STUDY

May 2, 2026

This study aimed to evaluate the impact of continuous flow insufflation of oxygen (CFIO) compared to bag-valve-mask (BVM) ventilation on neurological outcomes in adults who experienced out-of-hospital cardiac arrest (OHCA). The findings revealed that patients receiving CFIO had significantly lower odds of achieving a favorable neurological outcome at 30 days compared to those ventilated with BVM. This suggests that CFIO may not be as effective as BVM in improving neurological recovery following OHCA.

Combined short- and mid-latency SSEP amplitudes for early prediction of favorable neurological recovery after cardiac arrest

May 2, 2026

The authors aimed to determine whether mid-latency somatosensory evoked potentials (SSEPs) could enhance the early prediction of neurological recovery in comatose patients following cardiac arrest. Their study found that the P25-N30 SSEP amplitude was strongly associated with favorable neurological outcomes, demonstrating high sensitivity and specificity, and suggested that this measure could be a valuable tool for early prognostication in this patient population.

Impact of Cardiac Arrest in Patients with Cardiogenic Shock due to ST-Elevation Myocardial Infarction

Apr 22, 2026

The authors aimed to compare the clinical characteristics, management, and survival outcomes of patients with cardiogenic shock (CS) due to ST-elevation myocardial infarction (STEMI), differentiating between those without cardiac arrest (STEMI-CS-no CA), those with out-of-hospital cardiac arrest (STEMI-CS-OHCA), and those with in-hospital cardiac arrest (STEMI-CS-IHCA). The study found that patients with IHCA had worse clinical profiles and significantly higher mortality rates compared to those without cardiac arrest, highlighting the impact of cardiac arrest on long-term survival in this patient population.

Uniform reporting of outcomes from resuscitation education research: the resuscitation education Utstein style: a consensus report from the International Liaison Committee on Resuscitation

Apr 20, 2026

The authors aim to establish standardized reporting outcomes for resuscitation education research to enhance comparability and synthesis of study results. Through a Delphi process, they identified 16 outcome categories with specific measures for both healthcare providers and laypeople, culminating in the Resuscitation Education Outcomes Pyramid. This framework is intended to improve the quality of systematic reviews and ultimately inform better educational guidelines and clinical practices in resuscitation.

EEG-guided early cessation of sedation and TTM in patients after cardiac arrest: a feasibility and safety study

Apr 19, 2026

The authors aimed to investigate the feasibility and safety of early cessation of sedation and targeted temperature management (TTM) in comatose patients after cardiac arrest who exhibit a favorable EEG pattern within 12 hours. Their study found that early withdrawal of sedation and TTM significantly reduced the duration of mechanical ventilation and ICU length of stay without increasing complications, although it was underpowered to assess long-term neurological outcomes. The findings suggest that tailored approaches based on EEG patterns may enhance patient care, warranting further research.
