Randomized Controlled Trial
Postresuscitation oxygen reserve index-guided oxygen titration in out-of-hospital cardiac arrest survivors: a randomised controlled trial.
Hyperoxia after return of spontaneous circulation is potentially harmful, and oxygen titration in a prehospital setting is challenging. This study aimed to compare outcomes of oxygen reserve index-supported prehospital oxygen titration during prehospital transport with those of standard oxygen titration. ⋯ Oxygen reserve index- combined with pulse oximetry-based prehospital oxygen titration did not significantly improve the normoxia index compared with standard oxygen titration based on pulse oximetry alone (NCT03653325).

Randomized Controlled Trial
Treatment Effects of Blood Pressure Targets and Hemodynamics According to Initial Blood Lactate Levels in Comatose Out-of-hospital Cardiac Arrest Patients - A Sub Study of the BOX Trial.
Out-of-hospital cardiac arrest (OHCA) survivors remaining comatose are often circulatory unstable with high mortality in the first days following resuscitation. Elevated lactate will reflect the severity and duration of hypoperfusion in cardiac arrest. Further, the severity of hypoperfusion could modify the effect on survival of different mean arterial blood pressure (MAP) targets. ⋯ Comatose OHCA patients with high initial lactate levels required more vasoactive drugs on the first two days of ICU admission to meet the blood pressure target and had a poorer prognosis. No indication that aiming for a higher MAP target is beneficial in patients with an initial high lactate level was found, however, given the post-hoc nature of this study, these results should be considered hypothesis-generating.

Multicenter Study Observational Study
Association of blood pressure with neurologic outcome at hospital discharge after pediatric cardiac arrest resuscitation.
Poor outcomes are associated with post cardiac arrest blood pressures <5th percentile for age. We aimed to study the relationship of mean arterial pressure (MAP) with favorable neurologic outcome following cardiac arrest and return of spontaneous circulation (ROSC). ⋯ In the first 6-hours post-ROSC, a lowest documented MAP between the 5th-74th percentile for age was associated with favorable neurologic outcome compared to MAP <5th percentile for age.

Close family members of cardiac arrest patients who survive to hospital discharge have elevated levels of psychological distress and caregiver burden. We assessed their preferences toward needs during hospitalization and beyond to inform intervention development. ⋯ Interventions focusing on information needs are among the top priorities for families of cardiac arrest survivors. Prospective studies testing these hypotheses-generating findings are needed to inform further intervention development.

Evidence for extracorporeal cardiopulmonary resuscitation (CPR) in refractory out-of-hospital cardiac arrest (OHCA) remains inconclusive. Recently, the INCEPTION-trial, comparing extracorporeal with conventional CPR, found no statistically significant difference in neurologically favorable survival. Since protocol deviations were anticipated, a pre-specified per-protocol analysis was foreseen. ⋯ A pre-planned, pre-specified per-protocol analysis of the INCEPTION-trial, found a higher survival with favorable neurological in patients undergoing ECPR versus CCPR for refractory shockable OHCA. This difference did not reach statistical significance, but results should be interpreted with care, in the light of the small remaining sample size.
