The influence of adrenaline during cardiopulmonary resuscitation (CPR) on the neurological outcome of cardiac arrest survivors is unclear. As little is known about the pathophysiological effects of adrenaline on cerebral oxygen delivery and cerebral metabolism we investigated its effects on parameters of cerebral oxygenation and cerebral metabolism in a pig model of CPR. ⋯ Both adrenaline doses resulted in short-lasting CPP peaks which did not translate into improved cerebral tissue oxygen tension and metabolism. Further studies are needed to determine whether other dosing regimens targeting a sustained increase in CPP, may lead to improved brain oxygenation and metabolism, thereby improving neurological outcome of cardiac arrest patients.

To summarise in a systematic review the effectiveness of interventions to treat foreign body airway obstructions (FBAO). ⋯ Key interventions successfully relieve FBAO, but may be associated with important harms. Guidelines for FBAO management should balance the benefits and harms of interventions.

We assessed the ability of the Out-of-Hospital Cardiac Arrest (OHCA) and the Cardiac Arrest Hospital Prognosis (CAHP) scores to predict neurological outcome following in-hospital cardiac arrest (IHCA). ⋯ In parallel with CAHP score, OHCA score could be used to early predict outcome at hospital discharge after IHCA. However, prediction accuracy for all scores remains modest, suggesting the use of other dedicated means to early predict IHCA patients' outcome.

Skill decay is a recognised problem in resuscitation training. Spaced learning has been proposed as an intervention to optimise resuscitation skill performance compared to traditional massed learning. A systematic review was performed to answer 'In learners taking resuscitation courses, does spaced learning compared to massed learning improve educational outcomes and clinical outcomes?' ⋯ Despite the very low certainty of evidence this systematic review suggests that spaced learning can improve skill performance at 1 year post course conclusion and skill performance between course conclusion and 1 year. There is a lack of data from this educational intervention on skill performance in clinical resuscitation and patient survival at discharge with favourable neurological outcomes.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) during cardiopulmonary resuscitation (CPR) increases coronary and cerebral perfusion pressure, which might improve neurologically intact survival after refractory cardiac arrest. We investigated the feasibility of REBOA during CPR in the emergency department. ⋯ In this pilot trial, REBOA during CPR was successful in 60% of attempts. Long resuscitation times before start of the procedure might explain difficult insertion and missing effects. Nevertheless, insertion of REBOA in patients suffering from non-traumatic cardiac arrest is feasible and might increase coronary and cerebral perfusion pressures and perfusion.
