By evaluating tape recordings of true cardiac arrest calls, to judge the dispatchers ability to (a) identify cases as suspected cardiac arrest (CA), (b) give the case the right priority, (c) identify CA cases suitable for dispatcher-assisted, telephone-guided cardiopulmonary resuscitation (T-CPR) and (d) accomplish T-CPR. ⋯ (1) In the majority of the interviews, the quality was very high, while in one-third, serious criticism could be voiced. (2) In our study, only one-third (95% confidence interval, 22-41) of CA cases were suitable for T-CPR, and T-CPR was performed in only 8% of the 99 cases. (3) To optimise the dispatcher ability to identify suspected CA and initiate T-CPR, both medical knowledge and practical training are needed, preferably with protocols for pre-arrival instructions.

Comparative Study Clinical Trial
Finger position for chest compressions in cardiac arrest in infants.
To determine whether the recommended method of locating finger position for chest compression in infant cardiac arrest can cause pressure on the abdomen or xiphisternum. ⋯ If any infant in this study had chest compressions performed by any of the adults, using the recommended method, pressure would be exerted on the xiphisternum or abdomen. We suggest changing the method of locating finger position, to one using sternal anatomy.

Comparative Study
Adenosine by aortic flush fails to augment the brain preservation effect of mild hypothermia during exsanguination cardiac arrest in dogs - an exploratory study.
Most trauma cases with rapid exsanguination to cardiac arrest (CA) in the field, as well as many cases of normovolemic sudden cardiac death are 'unresuscitable' by standard cardiopulmonary-cerebral resuscitation (CPCR). We are presenting a dog model for exploring pharmacological strategies for the rapid induction by aortic arch flush of suspended animation (SA), i.e. preservation of cerebral viability for 15 min or longer. This can be extended by profound hypothermic circulatory arrest of at least 60 min, induced and reversed with (portable) cardiopulmonary bypass (CPB). ⋯ In both groups, ischemic neurons were as prevalent in the basal ganglia and neocortex as in the cerebellum and hippocampus. The mild hypothermic aortic flush protocol is feasible in dogs. The adenosine strategy used does not abolish the mild histologic brain damage.

59 years old. Only 1% had attended the course because of their own or a relative's cardiac disease. Ninety-four per cent believed there was a minor to major risk of serious disease transmission while performing CPR. ⋯ In four of six scenarios, respondents from rural areas were significantly more positive than respondents from metropolitan areas about starting CPR. In conclusion, readiness to perform CPR on a known person is high among trained CPR rescuers, while hesitation about performing CPR on a stranger is evident. Respondents from rural areas are more frequently positive about starting CPR than those from metropolitan areas.
