A 4-1/2-year-old girl with a one-year history of juvenile rheumatoid arthritis was admitted with severe respiratory distress requiring endotracheal intubation. Arthritis of the cricoarytenoid joint was diagnosed and she responded well to intubation and high-dose steroids. Although well described in adults, this is only the third case report of a child afflicted with arthritis of the cricoarytenoid joint.

To evaluate the hypothesis that all victims of severe blunt trauma require a pelvic radiograph, we prospectively studied all such patients admitted to the Southern New Jersey Regional Trauma Center during a seven-month period. All patients were classified as unconscious; impaired; awake, alert, and symptomatic; or alert, oriented, and asymptomatic for pelvic fracture on admission. All underwent a plain anterior-posterior radiograph of the pelvis. ⋯ These occurred in seven of 36 unconscious patients, 11 of 96 impaired patients, and eight of 23 symptomatic patients. No fractures were identified in 110 awake, alert, oriented, and asymptomatic patients (P less than .0001). We conclude that pelvic radiographs are required in unconscious or impaired victims of severe blunt trauma and those with signs or symptoms of pelvic fractures but are not required in the awake, alert, and asymptomatic patient.

A program to instruct ground and aeromedical prehospital emergency medical system providers in the intraosseous infusion technique was developed and implemented. Paramedics and flight nurses received training through lectures and performance of the procedure in several animal models. The records of attempts on 15 patients who subsequently received intraosseous infusions were then reviewed. ⋯ No serious sequelae were noted, but most patients did not survive and the ability of this study to detect sequelae may be limited. These data suggest that intraosseous infusion is a safe and reliable technique in the prehospital setting. Research is needed to study this technique in more detail.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of epinephrine and methoxamine for resuscitation from electromechanical dissociation in human beings.
Electromechanical dissociation (EMD) is an organized electrical depolarization of the heart without synchronous myocardial fiber shortening and, therefore, without cardiac output. Patients in EMD have a poor prognosis for resuscitation and long-term survival. The beneficial effect in resuscitation of epinephrine, the adrenergic agent currently recommended, has been shown to depend on stimulation of alpha-adrenergic vasoconstriction. ⋯ The advanced cardiac life support (ACLS) algorithm (current at the time of our study) for resuscitation from EMD was used, with the blinded study drug (epinephrine 1 mg or methoxamine 10 mg) administered where the algorithm calls for epinephrine. Calcium and isoproterenol also were used in the majority of cases according to ACLS standards but never prior to the use of methoxamine or epinephrine. Survival data are summarized as: survival less than one hour, 22 patients receiving methoxamine, 22 receiving epinephrine; one to six hours, 15 patients receiving methoxamine, 13 patients receiving epinephrine; six to 12 hours, one patient receiving epinephrine; more than 24 hours but not surviving to discharge, three patients receiving methoxamine, two patients receiving epinephrine; and survival to discharge, one patient receiving epinephrine.(ABSTRACT TRUNCATED AT 250 WORDS)

Carbon monoxide (CO) is the leading toxic cause of death in the United States today. Unsuspected exposure to this gas will sometimes result in clinically significant, but undiagnosed, toxicity. A high incidence of such unsuspected exposures would make screening for these worthwhile among high-risk populations. ⋯ Of a condensed subgroup of 152 patients defined retrospectively by chief complaint, eight (5.3%) had abnormal values. We conclude that routine screening of ED patients for unsuspected CO exposure is not practical. Although yield increases when patients are screened in a more selective manner on the basis of chief complaint, such an increase still does not appear to justify the screening process.
