Dispatcher-assistance in lay rescuer infant CPR: Promoting the enhancement of the guiding protocol.
In the 2021 guidelines of the European Resuscitation Council (ERC) on infant CPR, a two-thumb encircling technique (TTET) is advised instead of the former two-finger technique (TFT), even for single rescuers. It is however unclear if this is also feasible and effective in case of dispatcher-assisted CPR by untrained bystanders and was explored in a cross-over infant manikin study including CPR-trained students and lay people. ⋯ Results suggest it is feasible to advice single lay rescuers to perform TTET as part of a dispatcher-assisted CPR protocol, although we identified an ongoing risk, regardless of the technique advised, of suboptimal compression depth. Further research should be performed to confirm these preliminary data and explore optimal protocols for dispatcher-assisted infant CPR.

Frailty is associated with increased 30-day mortality and non-home discharge following perioperative cardiac arrest. We estimated the predictive accuracy of frailty when added to baseline risk prediction models. ⋯ Incorporating frailty did not significantly improve predictive accuracy of models for 30-day mortality and non-home discharge following perioperative resuscitation. Thus, demonstrated associations between frailty and outcomes of perioperative resuscitation may not translate into improved predictive accuracy. When engaging patients in shared decision-making regarding do-not-resuscitate orders perioperatively, providers should acknowledge uncertainty in anticipating resuscitation outcomes.

Out-of-hospital cardiac arrest (OHCA) patients from minoritized communities have lower rates of initial shockable rhythm, which is linked to favorable outcomes. We sought to evaluate the importance of initial shockable rhythm on OHCA outcomes and factors that mediate differences in initial shockable rhythm. ⋯ We included 22,730 OHCAs from majority White (21.1% initial shockable rhythm), 4,749 from majority Black (15.3% shockable), and 16,054 majority Hispanic/Latino (16.1% shockable) communities. Odds of favorable neurologic outcome were lower for majority Black (0.4 [0.3-0.5]) and Hispanic/Latino (0.6 [0.6-0.7]). While adjusting for bCPR minimally changed outcome odds, adjusting for shockable rhythm increased odds for Black (0.5 [0.4-0.5]) and Hispanic/Latino (0.7 [0.6-0.8]) communities. On mediation analysis for majority Black, the top mediators of initial shockable rhythm were public location (14.6%), bystander witnessed OHCA (11.6%), and female gender (5.7%). The top mediators for majority Hispanic/Latino were bystander-witnessed OHCA (10.2%), public location (3.52%), and bystander CPR (3.49%), CONCLUSION: Bystander-witnessed OHCA and public location were the largest mediators of shockable rhythm for OHCAs from minoritized communities.

Achievement of adequate ventilation skills during training courses is mainly based on instructors' perception of attendees' capability to ventilate with correct rate and chest compression:ventilation ratio, while leading to chest raising, as evidence of adequate tidal volume. Accuracy in evaluating ventilation competence was assessed in 20 ACLS provider course attendees, by comparing course instructors' evaluation with measures from a ventilation feedback device. ⋯ Deploying quality ventilation during CPR is a skill whose acquisition starts with effective training. Therefore, course instructors' capability to accurately evaluate attendees' ventilation maneuvers is crucial.
