Comparative Study
Hospital-wide first-responder automated external defibrillator programme: 1 year experience.
The first year experience with a hospital-wide first-responder automated external defibrillator (AED) programme implemented in a 683-bed University Hospital is reported. Throughout the hospital, 14 "AED access spots" were identified which could be easily reached from all wards and diagnostic rooms within 30s. AEDs were installed (Lifepak 500; Medtronik PhysioControl Corp., Redmond, USA, equipped with a Biolog 3000i portable ECG monitor; Micromedical Industries Ltd., Labrador, Australia). ⋯ In 18 of 27 cases in which the AED was installed promptly, the primary arrest rhythm was either VT or VF, and the AED delivered a shock. For this subgroup, the rate of return of spontaneous circulation and the rate of discharge at home were 88.9 and 55.6%, respectively. This encourages us to extend the concept of first-responder AED-defibrillation throughout our hospital.

Comparative Study
Providing automated external defibrillators to urban police officers in addition to a fire department rapid defibrillation program is not effective.
The aim of this study was to determine if providing automated external defibrillators (AEDs) to urban police officers would increase the proportion of patients with out-of-hospital cardiac arrest (OOH-CA) who were discharged alive from the hospital. ⋯ Equipping police cars with AEDs in an urban area where the fire department-based first response system also carries defibrillators did not improve the hospital discharge survival rate for victims of OOH-CA.

Comparative Study
The use of routine laboratory data to predict in-hospital death in medical admissions.
The ability to predict clinical outcomes in the early phase of a patient's hospital admission could facilitate the optimal use of resources, might allow focused surveillance of high-risk patients and might permit early therapy. We investigated the hypothesis that the risk of in-hospital death of general medical patients can be modelled using a small number of commonly used laboratory and administrative items available within the first few hours of hospital admission. Matched administrative and laboratory data from 9497 adult hospital discharges, with a hospital discharge specialty of general medicine, were divided into two subsets. ⋯ The finding that the risk of hospital death can be predicted with routinely available data very early on after hospital admission has several potential uses. It raises the possibility that the surveillance and treatment of patients might be categorised by risk assessment means. Such a system might also be used to assess clinical performance, to evaluate the benefits of introducing acute care interventions or to investigate differences between acute care systems.

Comparative Study
Evaluation of out-of-hospital cardiopulmonary resuscitation with resuscitative drugs: a prospective comparative study in Japan.
This study aimed at evaluating two emergency medical service systems, one in which emergency life-saving technicians (ELSTs) are allowed to administer epinephrine (adrenaline) to patients with out-of-hospital cardiac arrest and one in which ELSTs are allowed to administer epinephrine, lidocaine, and atropine. ⋯ Use of resuscitative drugs for non-traumatic prehospital CPR appears to be effective in terms of resuscitation rates and 1-month survival rates.

In out-of-hospital emergencies, including cardiac arrest, securing the airway and providing adequate lung ventilation are of paramount importance. Tracheal intubation is perceived as the gold standard technique and it is recommended by International Guidelines, but non skilled personnel often find the procedure difficult to achieve. Supraglottic devices are a good alternative in these situations, because they are superior to a bag-valve-mask for lung ventilation and offer better protection from aspiration. ⋯ The laryngeal tube remained in the correct position throughout resuscitation attempts in 93.3% of cases, while in two patients (6.6%) it became dislodged. In a subjective evaluation of the manoeuvre by nurses (ease of insertion, adequacy of ventilation, protection from aspiration), 86.7% of them expressed a positive opinion. The laryngeal tube appeared to be a reliable device for nurses to manage the airway in out-of-hospital emergencies.
