Resuscitation

Survival from traumatic cardiopulmonary arrest (TCA) has been reported at a rate as low as 0-2.6% in the civilian pre-hospital setting, and many consider resuscitation of this group to be futile. The aim of this investigation was to describe patients who received cardiac massage during TCA in a battlefield setting; we also aimed to identify predictors of survival. ⋯ We report a 13% survival to 30 days among all patients receiving cardiac massage in a battlefield setting. Closed-chest cardiac massage predicted survival among IH TCA victims who also received intravenous medications in this review of combat-related TCA.

We investigated the mechanism and extent of myocardial injury associated with out-of-hospital cardiac arrest (OHCA). ⋯ Significant myocardial injury associated with OHCA occurs in the presence of acute culprit lesion while extent of myocardial injury in stable or absent coronary disease is significantly smaller and correlates with the duration and intensity of cardiac resuscitation. Admission cTnI, although combined with post-resuscitation ECG, have insufficient accuracy to securely predict presence of acute culprit lesion.

To investigate whether a ventilation rate ≤10 breaths min-1 in adult cardiac arrest patients treated with tracheal intubation and chest compressions in a prehospital setting is associated with improved Return of Spontaneous Circulation (ROSC), survival to hospital discharge and one-year survival with favourable neurological outcome, compared to a ventilation rate >10 breaths min-1. ⋯ A ventilation rate ≤10 breaths min-1 was not associated with significantly improved outcomes compared to a ventilation rate >10 breaths min-1. No other adequate cut-off value could be proposed.
