To evaluate the outcome and quality of in-hospital cardiopulmonary resuscitation (CPR), and factors affecting the outcome. ⋯ In our setting, survival to discharge is 6.9%. Initial survival rate was strongly associated with being in a monitored area. Defibrillators and the critical care areas were insufficient.

Clinical Trial
Eighth grade students become proficient at CPR and use of an AED following a condensed training programme.
To evaluate a new, 1-h, condensed training programme to teach continuous chest compression cardiopulmonary resuscitation (CCC-CPR) and automated external defibrillator (AED) skills to a cohort of eight grade public school students. ⋯ With our focused, condensed training program, eighth grade public school students became proficient in CCC-CPR and AED use. This is the first study to document the ability of middle school students to learn and retain CCC-CPR and AED skills for adult sudden cardiac arrest victims with such a curriculum.

Implementing prehospital advanced life support (ALS) services requires more medical and societal resources in training and equipment. The actual demand for ALS services in our communities was not clear. To ensure good use of expensive resources, it is important to evaluate the demand and appropriateness of ALS services before full-scale implementation takes place. ⋯ Around nine percent of EMS calls demand ALS services. The current triage performance for proper ALS dispatch was suboptimal. A correct ALS dispatch protocol and more dispatcher training programmes should be established in the communities to ensure best use of valuable ALS resources.

To study the reliability and validity of a scoring instrument for the assessment of neonatal resuscitation skills in a training setting. ⋯ A useful and valid instrument with good intra-rater and reasonable inter-rater reliability is now available for the assessment of neonatal resuscitation skills in a training setting. Its reliability can be improved by using a more advanced manikin and by training of the raters.

There is growing evidence that microcirculatory blood flow is the ultimate determinant of the outcome in circulatory shock states. We therefore examined changes in the microcirculation accompanying the most severe form of circulatory failure, namely cardiac arrest and the effects of subsequent cardiopulmonary resuscitation. Ventricular fibrillation was electrically induced in nine pigs and untreated for 5min prior to beginning closed chest cardiac compression and attempting electrical defibrillation. ⋯ In animals that were successfully resuscitated, microvascular flow was significantly greater after 1 and 5min of chest compression than in animals with failed resuscitation attempts. Microvascular blood flow was highly correlated with coronary perfusion pressure (r=0.82, p<0.01). Microvascular blood flow in the sublingual mucosa is therefore closely related to coronary perfusion pressure during cardiopulmonary resuscitation and both are predictive of outcome.
