We aimed to reduce response times and time to defibrillation for out-of-hospital cardiac arrest patients through fire first-responders equipped with automatic external defibrillators (AEDs). The fire first-responders were added as an extra tier to the existing two-tired ambulance response. ⋯ The results from this study suggest that fire officers can be successfully trained in the use of AEDs and can integrate well into a medical response role. The combined response of ambulance and fire personnel significantly reduced the response interval and reduced time to defibrillation. This suggests that in appropriate situations other agencies could be considered for involvement in co-ordinated first-responder programs.

Severe neurological deficits are common characteristics of patients surviving cardiopulmonary resuscitation (CPR) or isolated severe head trauma (SHT). For comparative evaluation of underlying pathomechanisms, 22 patients with out-of-hospital cardiac arrest and successful CPR as well as 10 patients with SHT were included in our prospective study. Circulating S-100B was determined as an indicator of cellular brain damage. ⋯ Both clinical entities seem to be associated with early transient cellular brain damage as shown by prolonged rapidly increasing and subsequent fall in S-100B serum levels. In contrast, the prolonged elevation of circulating IL-8, sE-selectin and PMN-elastase may indicate a very similar systemic inflammatory response by endothelial cells and neutrophils initiated by ischaemia and reperfusion injury in both conditions. Further studies should be carried out to determine the cause and the prognostic value of these biochemical parameters in relation to long-term neurological outcome.

patients with cardiac arrest have a high mortality and the long-term outcome is doubtful. The prognosis is mainly dependent on clinical parameters. S-100 and neurone specific enolase (NSE) are established biochemical markers of central nervous system (CNS) injury. The purpose of this study was to validate the use of serum determinations of S-100 and NSE with neurological investigations in regard to brain damage and long-term outcome after cardiac arrest. ⋯ the serum levels of S-100 and NSE increased after cardiac arrest due to the anoxic brain damage. The determination of S-100 and NSE can be used as an adjunct to predict long-term outcome after cardiac arrest.

Mass cardiopulmonary resuscitation (CPR) 99 in Singapore was a large-scale multi-organisational effort to increase awareness and impart basic cardiac life support skills to the lay public. Mass CPR demonstrations followed by small group manikin practice with instructor guidance was conducted simultaneously in three centres, four times a day. ⋯ Two surveys, for 'I's and 'P's were conducted with respondent rates of 65.8% and 50%, respectively. 73.6% of the P-respondents ('P-R's) indicated that they attended the event to increase their knowledge. 66.9% were willing to attend a more comprehensive CPR course. Concerns and perceptions in performing bystander CPR were assessed.
