Two recent peer-reviewed studies examine care before and after hospital arrival: a prehospital resuscitation bundle for septic shock and the duration of cooling after cardiac arrest. Here are their findings, limitations, and relevance to EMS clinicians.

Prehospital septic shock: a one-hour bundle did not establish a mortality benefit
Published August 10, 2026 · Critical Care Medicine
A French multicenter, open-label, cluster-randomized trial evaluated a mobile-ICU resuscitation bundle incorporating antibiotics, fluids, and additional therapies when indicated. Among 381 analyzed patients, 28-day mortality was 22% with the bundle and 27% with usual care. The reported risk ratio was 0.81 (95% confidence interval, 0.61–1.08); the difference was not statistically significant. [1]
Why it matters to EMS: The study examines a specific approach to initiating intensive sepsis treatment before hospital arrival. Its findings do not establish that early sepsis care is ineffective or that individual bundle components lack benefit.
Keep the limitations in view: Enrollment was uneven between groups, and differences in delivered care were small. French mobile-ICU teams may differ substantially from other EMS systems. Although published in 2026, the trial enrolled patients in 2016–2018. [1]
Beyond the handoff: longer cooling did not improve outcomes in ICECAP
Published August 5, 2026 · JAMA
The ICECAP randomized clinical trial included 1,158 comatose survivors of out-of-hospital cardiac arrest at 71 US hospitals. Researchers compared different durations of therapeutic hypothermia at 33°C, ranging from 6 to 72 hours. Increasing cooling duration did not improve neurological outcomes. The trial met a prespecified stopping rule at an interim analysis. [2]
Why it matters to EMS: Understanding the hospital phase of post-arrest care gives clinicians useful context for the patient’s continuing treatment and questions families may ask about temperature management.
Keep the limitations in view: Participants were selected patients already receiving therapeutic hypothermia. The trial did not compare cooling with no cooling, evaluate prehospital cooling, or establish that six hours should become the standard. Its findings address treatment duration within the studied population. [2]
