The urban emergency department is routinely asked to manage not only medical emergencies, but also a great variety of social emergencies. This situation is caused in part by budgetary constraints which prevent other agencies from providing 24-hour coverage. ⋯ A case is presented which raises the issues of confidentiality and liberty in the fiduciary relationship between doctor and patient. The concept of personal care is found to be paramount.

Comparative Study
Mouth-to-mask ventilation: a superior method of rescue breathing.
Tidal volumes achieved using endotracheal intubation with a self-inflating bag were compared to those achieved with the esophageal obturator airway, a bag-valve mask system, and mouth-to-mask ventilation in an experimental model employing 18 unskilled and 4 partially skilled rescuers. When compared to mean tidal volumes achieved with endotracheal intubation (1,193 ml with unskilled, 942 ml with semi-skilled rescuers), ventilation with the bag-valve-mask system was significantly less (509 and 495 ml tidal volumes) and was, in fact, well below the value of 800 ml recommended for rescue breathing. Mouth-to-mask ventilation produced tidal volumes (1,093 ml and 1,200 ml) not significantly different from those seen with endotracheal intubation. If clinical findings confirm these experimental results, mouth-to-mask ventilation should replace the bag-valve-mask system in the initial management of respiratory arrest.

Because asthmatics have the highest utilization rate (11%) kin our emergency department (ED) observation unit (OU), we conducted a study correlating predictors of the need for OU therapy to initial disposition (ID) and final disposition (FD) using chart audit of treated asthmatics. Twenty-four clinical variables. (historical, physiological, laboratory, therapy response) were examined utilizing chi-square and Student's t tests. Forty-six asthmatics were treated during a four-month period in 1980. ⋯ Clinical variables correlating significantly with definitive therapy based on ID and FD were historical; symptoms greater than 24 hours, prior OU admissions, and prior hospitalizations. We conclude that the OU is appropriate, safe, and less expensive than admission; is not used for procrastination in decision making and decreases the hospitalization rate. Historical data correlated significantly with both ID and FD, while clinical variables were of little predictive value.
