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.

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.

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.

The Guidelines 2000 for cardiopulmonary resuscitation recommend shock delivery to victims in ventricular fibrillation within 5 min of call receipt by the Emergency Medical Services. In an effort to achieve this goal, in some parts of the United States, police officers have been trained to use automated external defibrillators (AEDs). We undertook a 3-year pilot evaluation of the use of AEDs by City of London police (CPOL) officers. ⋯ Two (15%) of these victims survived to hospital discharge. This study has confirmed the feasibility of training police officers in the UK to use AEDs as first responders. The call received to arrival on scene interval should be reduced by improvements in communication between LAS and CPOL.

Emergencies arising during commercial airline flights may have serious consequences. We report the experience of the Paris Emergency Medical Service (SAMU) in providing in-flight assistance to Air France between 1989 and 1999. ⋯ However the relative frequency of cardiac and neurological emergencies in our analysis supports the necessity of carrying adequate medical equipment and of having direct access to expert medical advice. The results suggest the requirement for a rigorous prospective epidemiological study of in-flight emergencies to evaluate the effectiveness of current practice and possible modifications of equipment and protocols for patient management.
