Each year, about 1,250,000 people in the United States experience an acute myocardial infarction (AMI). Emergency medical services (EMS) systems play a key part in the prehospital care and transportation of AMI patients. ⋯ In order to improve the prehospital care provided to AMI patients, this article by the Access to Care Subcommittee of the National Heart Attack Alert Program Coordinating Committee makes a number of recommendations regarding the staffing and equipping of EMS systems. The recommendations cover the "chain of survival" concept, universal and enhanced 9-1-1, emergency medical dispatching, ground ambulance specifications, automated external defibrillators, advanced life support coverage, medical direction, 12-lead electrocardiograms, and prehospital thrombolysis.

The purpose of this study was to determine the efficacy of a mannequin for training emergency caregivers in the technique of retrograde intubation. This was a descriptive study using duration of time needed for completion of intubation as a measure of success. A cohort of 88 Emergency Medical Service (EMS) personnel included prehospital caregivers, registered nurses, and respiratory care practitioners. ⋯ It was concluded that retrograde intubation can be taught easily with a mannequin and that this skill can be learned by emergency caregivers by modeling. Bag-valve-mask ventilation can be performed at any time without the need to restart or interrupt the procedure. Retrograde intubation can be introduced as an intubation technique for the difficult airway encountered by EMS personnel.

Iontophoresis is a painless technique for topical anesthesia that uses an electric field to drive charged ions across an epithelial surface. The safety of this technique for laceration repair has never been demonstrated. The purpose of this study was to investigate the effect of iontophoretic fields on rapidly proliferating cells involved in laceration wound healing. ⋯ A total of 48 wounds were assessed for wound healing, 24 of which received lidocaine via iontophoresis and 24 lidocaine via injection. The power of the study to determine a 40% difference between the two groups was 0.8. There was significantly more granuloma and granulation tissue formation in the iontophoresis group than in the injected lidocaine control group (P = .0004, Fisher's exact test).(ABSTRACT TRUNCATED AT 250 WORDS)

Emergency medical telephone calls (ie, those made to 9-1-1 or 7-digit emergency numbers) are directed to emergency medical dispatchers (EMDs) who are responsible for quickly obtaining critical pieces of information from the caller, then activating an appropriate level of emergency medical services (EMS) response and providing the caller with patient care instructions until medical help arrives. The impact of well-trained, medically managed EMDs on the early care of potential acute myocardial infarction (AMI) patients is believed to be beneficial. However, standards for emergency medical dispatching vary widely across the nation. To improve emergency medical dispatching for AMI patients in the United States, this article by the Access to Care Subcommittee on behalf of the National Heart Attack Alert Program makes a number of recommendations regarding the use of medical dispatch protocols, provision of dispatch life support, EMD training, EMD certification, and emergency medical dispatch quality control and improvement processes.
