Multicenter Study Comparative Study
Evaluation of the performance of a modified Acute Physiology and Chronic Health Evaluation (APACHE II) scoring system for critically ill patients in emergency departments in Hong Kong.
Numerous prognostic predictive models have been developed for critically ill patients, many of which are primarily designed for use in intensive care units. The objective of this study was to evaluate the accuracy of a modified Acute Physiology and Chronic Health Evaluation (APACHE II) scoring system in predicting the mortality for critically ill patients managed in emergency department (ED) resuscitation rooms in Hong Kong. ⋯ The modified APACHE II score is only a moderate predictor of mortality for critically ill patients managed in the resuscitation rooms of EDs in Hong Kong. A more ED specific scoring method is required.

The primary aim was to derive a new termination of resuscitation (TOR) clinical prediction rule for advanced life support paramedics (ALS) and to measure both its pronouncement rate and diagnostic test characteristics. Secondary aims included measuring the test characteristics of a previously derived and published basic life support termination of resuscitation (BLS TOR) clinical prediction rule [Morrison LJ, Visentin LM, Kiss A, et al. Validation of a rule for termination of resuscitation in out-of-hospital cardiac arrest. N Engl J Med 2006;355(5):478-87] on the same cohort of patients for comparison purposes. ⋯ Cardiac arrest patients may be considered for prehospital ALS TOR when there is no ROSC prior to transport, no shock delivered, no bystander CPR and the arrest was not witnessed by bystanders or EMS. A single EMS termination clinical prediction rule for all levels of providers would be optimal for EMS systems to implement. Prospective evaluation of the ALS TOR clinical prediction rule in the hands of ALS providers will be required before implementation.

Randomized Controlled Trial Comparative Study
Influence of air-purifying respirators on the simulated first response emergency treatment of CBRN victims.
Medical first responders and emergency room personnel potentially are threatened by exposure to primary or secondary intoxication by chemical, biological, radiological or nuclear (CBRN) substances. The impact of personal respiratory protection by air-purifying respirators on the performance of resuscitation requires evaluation. This will help to improve major incident planning and measures for protecting medical staff. ⋯ Modern personal respiratory protection has only a negligible effect in the delay on the short term treatment during well defined simulated scenarios with a single CBRN casualty. Furthermore, air-purifying respirators with panoramic visors seem to allow a better orientation for medical first responders during simulated resuscitation.

Perimortem caesarean section is very rare, mostly resulting in high mortality of mother and/or fetus. We report a case of successful resuscitation of both mother and newborn following maternal cardiac arrest prior to delivery. Postoperative outcome was complicated by severe bleeding and coagulopathy following fibrinolysis and subcapsular hepatic haematoma. We consider a fast reaction time based on a special in-hospital emergency team for immediate caesarean section and an aggressive management of coagulopathy as major factors that led to both patients recovery without neurological sequelae.

A recently published study has shown that survival after out-of-hospital cardiac arrest (OHCA) in Göteborg is almost three times higher than in Stockholm. The aim of this study was to investigate whether in-hospital factors were associated with outcome in terms of survival. ⋯ An almost 2-fold difference in survival after OHCA between Stockholm and Göteborg appears to be associated with pre-hospital factors only (predominantly in form of prolonged intervals in Stockholm), rather than with in-hospital factors or patient characteristics.
