Resuscitation

To study factors associated with short-term and long-term survival after out-of-hospital cardiac arrest presenting with pulseless electrical activity (PEA). ⋯ The use of adrenaline during resuscitation was the only significant factor which was found to decrease the long-term survival. Among admitted patients, short delay to ROSC was the only factor associated with increased survival. Bystander-CPR and delays to the arrival of the FRU or to the initiation of ALS were not associated with survival. Therefore, it seems difficult to increase survival rates of PEA by improving the chain of survival. More effort should be put to education of the public to call for an ambulance before the cardiac arrest occurs.

Case Reports
Therapeutic hypothermia induced during cardiopulmonary resuscitation using large-volume, ice-cold intravenous fluid.
Therapeutic hypothermia after resuscitation improves outcome following prolonged out-of-hospital cardiac arrest. Laboratory studies suggest that this therapy may improve outcome further when induced during cardiopulmonary resuscitation. We report a case where therapeutic hypothermia was induced during cardiopulmonary resuscitation using large-volume (40 mL/kg), ice-cold (4 degrees C) intravenous fluid. ⋯ Treatment with a rapid intravenous infusion of large-volume (40 mL/kg), ice-cold (4 degrees C) fluid during cardiopulmonary resuscitation induces mild hypothermia and may provide neurological protection. Further clinical studies of this approach are warranted.

Out-of-hospital cardiac arrest (OHCA) accounts for 250.000-350.000 sudden cardiac deaths per year in the United States. The availability of automated external defibrillators (AEDs) promoted the implementation of public access defibrillation programs based on out-of-hospital early defibrillation by non-healthcare professionals. ⋯ The results of our meta-analysis demonstrate that programs based on CPR plus early defibrillation with AEDs by trained non-healthcare professionals offer a survival advantage over CPR-only in OHCA. The conclusions of our meta-analysis add to previous evidence in favour of developing public-health strategies based on AED use by trained layrescuers.

Randomized Controlled Trial Comparative Study
Instructions to "put the phone down" do not improve the quality of bystander initiated dispatcher-assisted cardiopulmonary resuscitation.
The quality of early bystander CPR appears important in maximizing survival. This trial tests whether explicit instructions to "put the phone down" improve the quality of bystander initiated dispatch-assisted CPR. ⋯ Instructions to "put the phone down" had no effect on the quality of bystander initiated dispatcher-assisted CPR in this trial.
