Comparative Study
ED length-of-stay and illness severity in dizzy and chest-pain patients.
Emergency department (ED) length of stay, illness severity, and patterns of ED-based testing can be used to compare different ED patient populations. To assess the relative significance of ED patients with dizziness and chest pain in emergency medicine practice, the investigators formed a retrospective chart review of 3,864 adults (age > or = 16 years) seen at the University of North Carolina Hospitals' ED during May and June of 1991. Patients were eligible if they had any complaint of dizziness (n = 259), nontraumatic chest pain (n = 168), or both (n = 18). ⋯ Chest-pain patients were more likely to undergo electrocardiogram and x-ray testing, whereas dizzy patients more often received testing such as brain computed tomography scanning (10.8% v 3.6%, P = .01). ED patients with dizziness and chest pain were similar with regard to ED length of stay. Given their overall similarities to the chest-pain group, dizzy patients appear to represent a significant population of ED patients and may warrant more clinical study.

Subcutaneous emphysema is an unusual complication of bronchiolitis. The investigators describe a patient with bronchiolitis who developed extensive subcutaneous emphysema. ⋯ Review of the literature shows a multitude of causes of subcutaneous emphysema. The vast majority of cases resolve without intervention.

This prospective, clinical study was performed to determine the utility of the syringe aspiration technique (SAT) to verify endotracheal tube (ETT) position. Ninety consecutive patients requiring urgent intubation in the emergency department or prehospital setting were enrolled in the study. ⋯ Ultimately, standard detection techniques were used to confirm ETT placement. The SAT was an accurate means of verifying ETT placement.

To investigate the epidemiology of out-of-hospital cardiac arrest in Taipei City, Taiwan, a prospective chart review and follow-up study was conducted by collecting the prehospital cardiac arrest record from 10 designated responsible emergency departments (EDs) from August 1, 1992 through May 31, 1993. Cases with the restoration of spontaneous circulation (ROSC) were followed up until discharged from hospital. The information gathered included age, sex, bystander cardiopulmonary resuscitation, response time (time elapsed from receiving the call to arrival on the scene), advanced cardiac life support (ACLS) time (time elapsed from receiving the call to arrival at the ED), initial cardiac rhythm in the ED, ROSC, survival to discharge from the hospital, underlying disease, past history, personal history, and neurological outcome at discharge. ⋯ Between cases of patients who had ROSC and those who died, the data were statistically significant, P = .0143, showing that ACLS time was shorter in the ROSC group (19.5 v 21.9 minutes). In analysis of underlying disease, definite and probable cardiac-origin sudden deaths were found in only 120 patients, which may extend the annual sudden cardiac death rates to be 0.0053%. In conclusion, the low resuscitation and survival rates in this country were because of delayed initiation of both basic life support and ACLS.(ABSTRACT TRUNCATED AT 250 WORDS)

To determine the safety and efficacy of intravenous adenosine as used in the emergency department (ED) for the treatment of presumed supraventricular tachycardia, the investigators performed a retrospective chart review in an urban, university-affiliated ED. Seventy-two consecutive patients were treated with intravenous adenosine for presumed supraventricular tachycardia. Of the 72 patients who were treated with adenosine, 46 patients had a confirmed diagnosis of supraventricular tachycardia. ⋯ No clinically significant adverse effects were noted among the study population. Intravenous adenosine is a safe and efficacious treatment for the emergent treatment of supraventricular tachycardia, including unstable patients (with hypotension and/or chest pain). It is also safe among patients initially presumed to have supraventricular tachycardia, who are later diagnosed with other arrhythmias.
