Resuscitation
-
To identify patients who should not have resuscitation started or continued. ⋯ CPR survival is problematic, and it is especially poor in field/BR arrests. Emergency squads should terminate CPR for pulseless patients after communicating with the ER physician. Age is not a determinant of recovery or survival. Arrest outside of the hospital, sepsis, three or more co-morbid conditions, previous CPR, asystole or resuscitation for >25 min all decrease the chance of hospital discharge and survival. Instituting or continuing CPR in a great majority of these patients is futile. Families should be so advised.

Low incidence of bystander-initiated cardiopulmonary resuscitation (CPR) is allegedly responsible for poor survival from out-of-hospital cardiac arrest (OHCA) in Japan. This study was conducted to determine significant predictors for survival after collapse-witnessed OHCA of presumed cardiac etiology to investigate the impact of bystander-initiated CPR. Logistic regression analysis of OHCA of presumed cardiac etiology was performed on retrospective data sets from three Japanese suburban communities. ⋯ Patient age (70 years or less/over 70 years), interval from collapse to EMS response, and bystander-initiated CPR were significantly associated with VF in an initial ECG. The effectiveness of bystander-initiated CPR for OHCA can be successfully predicted based on the interval from collapse to CPR and initial ECG rhythm. The increase in the proportion of bystander-initiated CPR from the present level of 20-50% would be expected to rescue another 1800 victims of OHCA per year in Japan.

Review Case Reports
Cardiac arrest during surgery and ventilation in the prone position: a case report and systematic review.
We present a case report of successful resuscitation following cardiac arrest in a patient undergoing surgery in the prone position. A systematic review of the literature identified 22 further cases. ⋯ Management of prone cardiac arrest may be improved by identification of high-risk patients, careful patient positioning, use of invasive monitoring and placement of self-adhesive defibrillator paddles. Suitable techniques for cardiopulmonary resuscitation including methods for chest compression, defibrillation and the management of air embolism are discussed.

If patients are to benefit from resuscitation, they must regain consciousness and their full faculties. In recent years, we have acquired important information about the natural history of neurological recovery from circulatory arrest. There are clinical tests that predict the outcome, both during ongoing cardiopulmonary resuscitation (CPR) and in the period after restoration of spontaneous circulation. ⋯ Ideally, no competent patient should be given a DNAR-status without his or her consent. No CPR-attempt should be stopped, and no treatment decision for a patient recovering after CPR should be taken without knowing and assessing the available information. Good ethical decision-making requires reliable facts, which we now know are available.
