Randomized Controlled Trial Comparative Study Clinical Trial
CPREzy: an evaluation during simulated cardiac arrest on a hospital bed.
CPREzy is a new adjunct designed to improve the application of manual external chest compressions (ECC) during cardiopulmonary resuscitation (CPR). The aim of this study was to determine the effect of using the CPREzy device compared to standard CPR during the simulated resuscitation of a patient on a hospital bed. Twenty medical student volunteers were randomised using a cross over trial design to perform 3 min of continuous ECC using CPREzy and standard CPR. ⋯ This was due to a higher number of low compressions (26% of total compressions for CPREzy versus 1% for standard CPR, P < 0.001). In conclusion, CPREzy was associated with significant improvements in ECC performance. Further animal and clinical studies are required to validate this finding in vivo and to see if it translates to an improvement in outcome in human victims of cardiac arrest.

Practice Guideline Guideline
Cardiopulmonary resuscitation standards for clinical practice and training in the UK.
The Royal College of Anaesthetists, the Royal College of Physicians, the Intensive Care Society and the Resuscitation Council (UK) have published new resuscitation standards. The document provides advice to UK healthcare organisations, resuscitation committees and resuscitation officers on all aspects of the resuscitation service. It includes sections on resuscitation training, resuscitation equipment, the cardiac arrest team, cardiac arrest prevention, patient transfer, post resuscitation care, audit and research. ⋯ The practice of resuscitation should be audited to maintain and improve standards of care. A do not attempt resuscitation (DNAR) policy should be compiled, communicated to relevant members of staff, used and audited regularly. Funding must be provided to support an effective resuscitation service.

Comparative Study
Should there be a change in the teaching of airway management in the medical school curriculum?
To evaluate the use of the Laryngeal Mask Airway (LMA), the oesophageal-tracheal combitube (ETC) and the tracheal tube (TT) by medical students, with a view to recommend changes to the medical school curriculum. ⋯ The use of the TT is difficult and the skills acquired by the medical students deteriorate significantly over time. The LMA and the ETC seem to have an advantage over the TT in that they are more easily learnt and the skills better retained. It is recommended that these alternative devices be included in the medical school curriculum for airway management.

To evaluate the characteristics, outcome and prognostic factors among children suffering from out of hospital cardiac arrest in Sweden. ⋯ Among children suffering from out of hospital cardiac arrest in Sweden that were not crew witnessed, the overall survival is low (4%). The chance of survival appears to be markedly increased if the arrest occurs outside the patients home compared with at home. No other strong predictors for an increased chance of survival could be demonstrated.

Comparative Study
A study comparing the usability of fully automatic versus semi-automatic defibrillation by untrained nursing students.
Current international guidelines prefer the use of semi-automatic external defibrillators (SAEDs) over fully automatic external defibrillators (FAEDs). However, there is a lack of evidence supporting this recommendation. We conducted a study of usability with nursing students comparing the FAED version against the SAED version of the Lifepak CR Plus AED (Medtronic, Redmond, USA). We hypothesized that FAED use would limit the number of operator-device interactions, thereby increasing compliance by the rescuer, safety and speed. ⋯ Despite a lack of BLS skills and AED training, the majority of students demonstrated safe and effective use of the AED. The use of the FAED version of the CR Plus resulted in increased compliance with the protocol and reduced variability in time to deliver three shocks. Further research is needed to confirm these findings in other groups of first responders.
