The AIDS epidemic is having an increasing impact on the practice of emergency medicine. In inner-city emergency departments, significant numbers of patients have unrecognized human immunodeficiency virus (HIV) infection. Transmission of HIV in the health care setting has been predominantly from exposure to patients' infected blood, but most of the exposures (80%) are due to injuries from sharp instruments. ⋯ However, due to methodologic limitations, these figures may be underestimations. The effectiveness of azidothymidine for postexposure prophylaxis has not been shown. Currently, the best protection against HIV and other blood-borne pathogens remains use of universal precautions.

Physician assistants (PAs) specially trained in emergency medicine can be used effectively to work with emergency medicine physicians to provide efficient and expedient high-quality patient care. The concept of using PAs in the emergency department is reviewed, and items of concern to professionals who are reluctant to use PAs are discussed. ⋯ The PA program at Beth Israel Medical Center is used as a case study to demonstrate the use and integration of the PA within the division of emergency services. Although a well-trained emergency physician is the gold standard for quality patient care, cost-effective quality care for certain patient complaints can be rendered acceptably by others.

Accuracy of interpretations of emergency department radiographs: effect of confidence levels.
We conducted a prospective study to assess the relationship between the interpretive agreement rate for emergency department radiographs and the degree of interpretive confidence. We hoped to identify a subset of ED radiographs that did not require mandatory review by a radiologist. For each of the 1,872 plain radiographs studied, emergency physicians assigned a confidence level to the interpretation before comparing it with the radiologist's dictated report. ⋯ No subset of radiographs had 100% agreement. Treatment was potentially altered in 38 patients as a result of the interpretive disagreement that occurred in 2% of studied radiographs. We conclude that the interpretive agreement rate increases in relation to interpretive confidence but that confidence levels cannot safely exclude certain radiographs from mandatory review by a radiologist.

Our approach to the management of fear and pain in the pediatric emergency department is presented. Tricks to attempt the gaining of rapport with frightened children in pain are noted, with emphasis on a developmental approach. The use of analgesic medications, local anesthetics, ketamine, and nitrous oxide as appropriate to emergency situations is outlined. Lastly, the guidelines of the American Academy of Pediatrics for outpatient sedation are reviewed.

Thirty-nine emergency cricothyrotomies were reviewed from the emergency department of Hennepin County Medical Center during the 4-year period ending December 1985. Due to technical changes in airway management and a desire to assess their impact, this experience was compared with a previously reported series of 38 emergency cricothyrotomies from the same department. Technical changes include the use of paralyzing agents, transtracheal needle ventilation, and the use of only vertical skin incisions and #4 Shiley tubes when cricothyrotomy is performed. ⋯ However, the tube was in the trachea in all cases, and acceptable ventilation was achieved. No patient developed a clinically significant hematoma or hemorrhage from cricothyrotomy. It is concluded that our technical changes in airway management have helped to decrease both the relative frequency of cricothyrotomy and the complication rate.
