Randomized Controlled Trial
Infectious complications after out-of-hospital cardiac arrest - a comparison between two target temperatures.
It has been suggested that target temperature management (TTM) increases the probability of infectious complications after cardiac arrest. We aimed to compare the incidence of pneumonia, severe sepsis and septic shock after out-of-hospital cardiac arrest (OHCA) in patients with two target temperatures and to describe changes in biomarkers and possible mortality associated with these infectious complications. ⋯ Patients who develop pneumonia, severe sepsis or septic shock after OHCA might have an increased mortality. A target temperature of 33°C after OHCA was not associated with an increased risk of infectious complications compared to a target temperature of 36°C. PCT and CRP are of limited value for diagnosing infectious complications after cardiac arrest.

Neurological emergencies can lead to cardiac arrest, and post-arrest patients can develop life-threatening neurological abnormalities. This study aims to estimate and characterize the use of early head CT (HCT), and its potential impact on post-resuscitation management. ⋯ Early HCT is not consistently performed after OHCA and may be heavily influenced by a patient's premorbid status and duration of arrest. Early HCT can demonstrate acute abnormalities that can result in significant changes in patient management.

Most survival outcomes in out-of-hospital cardiac arrest (OHCA) are provided by emergency medical services (EMS) without a doctor on board. Our objective was to determine such outcomes in a whole country with public physician-led EMS.

We sought to assess the relationship between mean arterial pressure (MAP) and clinical outcomes in comatose survivors of out-of-hospital cardiac arrest (OHCA). ⋯ In comatose survivors of OHCA treated with target temperature management, a higher mean MAP during the first 96h of admission is associated with increased survival. The association between mean MAP and clinical outcomes appears to be attenuated by increased age.

Amplitude spectral area (AMSA), an index for analysing ventricular fibrillation (VF) waveforms, is thought to predict the return of spontaneous circulation (ROSC) after electric shocks, but its validity is unconfirmed. We developed an equation to predict ROSC, where the change in AMSA (ΔAMSA) is added to AMSA measured immediately before the first shock (AMSA1). We examine the validity of this equation by comparing it with the conventional AMSA1-only equation. ⋯ Post-shock ROSC was accurately predicted by adding ΔAMSA to AMSA1. AMSA-based ROSC prediction enables application of electric shock to only those patients with high probability of ROSC, instead of interrupting chest compressions and delivering unnecessary shocks to patients with low probability of ROSC.
