Current guidelines suggest the use of epinephrine in patients with cardiac arrest (CA). However, evidence for increased survival in good neurological condition is lacking. In experimental settings, epinephrine-induced impairment of microvascular flow was shown. The aim of our study was to analyze the association between epinephrine treatment and intestinal injury in patients after CA. ⋯ In this small, single centre study, cumulative dose of epinephrine used in cardiac arrest patients was associated with an increase in biomarker indicative of intestinal injury and 6-month mortality.

In 2015, the Los Angeles Fire Department (LAFD) replaced the Medical Priority Dispatch System® (MPDS) with a new, homegrown Los Angeles Tiered Dispatch System (LA-TDS). The objective of this study was to assess the impact of this new dispatch system on telecommunicator-assisted CPR (T-CPR). ⋯ Implementation of the new Los Angeles Tiered Dispatch System was associated with decreased time to recognition of cardiac arrest and an increased rate of T-CPR compared to the previously used Medical Priority Dispatch System®.

Prehospital perimortem caesarean delivery (PCD) is a rarely performed procedure. In this study, we aimed to examine all PCDs performed by the four Helicopter Emergency Medical Services in the Netherlands; to describe the procedures, outcomes, complications, and compliance with the recommended guidelines; and to formulate recommendations. ⋯ There was a low incidence of maternal perimortem caesarean deliveries in The Netherlands. Only some neonates survived after PCD. It is recommended that PCD be performed as quickly as possible. Due to the delay, the mother has a far lower chance of survival than the neonate. In fatal cases, autopsy is strongly recommended.

Cardiac arrest can activate blood coagulation, which clinically manifests as obstruction of the microcirculation and multiple organ dysfunction. Thromboelastography (TEG) provides a rapid and comprehensive assessment of hemostatic processes, but there are limited data on the use of sequential TEG values during targeted temperature management (TTM) in out-of-hospital cardiac arrest (OHCA) survivors. The aim of this study was to investigate the prognostic value of coagulopathy assessed by repeated TEG to predict neurologically intact survival. ⋯ TEG results are available within minutes, and shorted R values or the absence of prolonged LY30 values in the initial phase are an early predictor of neurologically intact survival in successfully resuscitated OHCA patients.

Coronary angiogram (CA) may be useful after resuscitated out-of-hospital cardiac arrest (OHCA), but data regarding its benefit in patients with non-shockable initial rhythm without ST-segment elevation is scarce. We aimed to evaluate the prevalence of acute coronary syndrome (ACS) and survival in OHCA patients with non-shockable initial rhythm without ST-segment elevation and compare them to patients with shockable initial rhythm without ST-segment elevation. ⋯ Prevalence of ACS in patients without ST-segment elevation and non-shockable initial rhythm is extremely low, and survival extremely poor, therefore routine emergency CA does not seem beneficial in these patients.
