Randomized Controlled Trial Multicenter Study Comparative Study
TARGET TEMPERATURE MANAGEMENT OF 33°C AND 36°C IN PATIENTS WITH OUT-OF-HOSPITAL CARDIAC ARREST WITH INITIAL NON-SHOCKABLE RHYTHM - A TTM SUB-STUDY.
Despite a lack of randomized trials in comatose survivors of out-of-hospital cardiac arrest (OHCA) with an initial non-shockable rhythm (NSR), guidelines recommend induced hypothermia to be considered in these patients. We assessed the effect on outcome of two levels of induced hypothermia in comatose patient resuscitated from NSR. ⋯ Comatose patients after OHCA with initial NSR continue to have a poor prognosis. We found no effect of targeted temperature management at 33°C compared to 36°C in these patients.

Randomized Controlled Trial
The capability of professional- and lay-rescuers to estimate the chest compression-depth target: A short, randomized experiment.
In CPR, sufficient compression depth is essential. The American Heart Association ("at least 5cm", AHA-R) and the European Resuscitation Council ("at least 5cm, but not to exceed 6cm", ERC-R) recommendations differ, and both are hardly achieved. This study aims to investigate the effects of differing target depth instructions on compression depth performances of professional and lay-rescuers. ⋯ Professional and lay-rescuers have severe difficulties in correctly estimating distance on a sheet of paper. Professional-rescuers are able to yield AHA-R and ERC-R targets likewise. In lay-rescuers AHA-R was associated with significantly higher success rates. The inability to estimate distance could explain the failure to appropriately perform chest compressions. For teaching lay-rescuers, the AHA-R with no upper limit of compression depth might be preferable.
