This article reviews the influence of emergency medical systems and prehospital defibrillation on survival of sudden cardiac death. The historical perspective and epidemiologic considerations of prehospital sudden cardiac death are highlighted. ⋯ Influences of emergency medical services on outcome of prehospital cardiac arrest are reviewed, with emphasis on the role of dispatchers, emergency medical technicians, and paramedics. The recent emergence of prehospital automatic defibrillation by emergency medical technicians, first responders, and lay persons is discussed in depth, as it has great potential to positively influence outcome of prehospital sudden cardiac death.

Comparative Study
A comparison of four methods of testing emergency medical technician triage skills.
Triage skills are requisite for all providers of prehospital care. Methods of assessing the acquisition of triage skills vary in complexity and expense. In this study, 61 prehospital care providers classified 20 cases, divided into four groups of five cases each: moulaged live trauma victims, nonmoulaged live trauma victims, nonmoulaged manikin trauma victims, and written scenarios. ⋯ Analysis of variance revealed statistically significant differences among the four methods in both mean tagging scores (F3,235 = 8.63, P less than .0001) and mean ranking scores (F3,232 = 6.09, P less than .001). Multiple comparisons using Scheffe's test revealed that the mean tagging and ranking scores for moulaged live victims and written scenario methods were comparable and that both were significantly superior to the scores of the two other methods. However, a qualitative evaluation revealed that the providers greatly preferred triage of moulaged live victims to the other three methods.

Randomized Controlled Trial Clinical Trial
Use of rib belts in acute rib fractures.
The current treatment for uncomplicated rib fractures is the exclusion of associated injuries followed by symptomatic treatment with analgesics. Encouragement of deep breathing is also recommended to avoid secondary or delayed pulmonary complications. The use of circumferential rib belts in treating patients with acute rib fractures has been discouraged because of possible complications from restricted ventilation. ⋯ Four complications (one case of bloody pleural effusion requiring hospitalization, two cases of asymptomatic discoid atelectasis, and one case of allergic contact dermatitis) were identified, all occurring in the group of patients receiving rib belts. This pilot study indicates that while rib belts are widely accepted by patients for control of pain, they appear to be associated with an increased incidence of complications. Clinical studies with larger sample sizes will be needed to confirm these findings.
