Randomized Controlled Trial Comparative Study Clinical Trial
The efficacy of sublingual hyoscyamine sulfate and intravenous ketorolac tromethamine in the relief of ureteral colic.
A prospective, randomized, open-label, single-dose study was conducted in an emergency department (ED) of a tertiary care teaching hospital to evaluate the efficacy of hyoscyamine sulfate as compared to ketorolac tromethamine for the reduction of pain from ureteral colic in the ED. Patients were included if they were at least 18 years of age and presented to the ED with an initial history and physical examination consistent with ureteral colic. Ureteral calculi were confirmed by ultrasound or intravenous urogram. ⋯ Demographics and baseline pain scores were similar for each group. Decreasing trends in pain over time were observed for both treatment groups, with significantly greater pain reduction observed with ketorolac tromethamine as compared to hyoscyamine sulfate. Global evaluations of pain relief revealed better results in the ketorolac tromethamine group than in the hyoscyamine sulfate group, although this result was not statistically significant.

To describe the chronotoxicology of cocaine and its potential impact on emergency department (ED) staffing and services, Drug Abuse Warning Network (DAWN) data from a single urban university ED were retrospectively reviewed. The DAWN data reviewed spanned an 11-year period (1/1/83 through 12/31/93), and 3,762 patients were enrolled. Patients were included if the ED records included documentation of recent cocaine abuse prior to presentation to the ED. ⋯ For all patients using cocaine, there were two significant rhythms (P < .05) identified: a circadian rhythm that peaked at 1800 and a 12-hour rhythm that peaked at approximately noon and midnight. A significant rhythmicity was found among cocaine-using patients who presented during the study period. Increased or shift-adjusted staffing focusing specifically on psychosocial services, detoxification, and security during these peak hours may provide more efficient emergent care for this subpopulation of patients.

Airway control is the initial priority in the management of the injured patient. The purpose of this investigation was to evaluate the experience of an aeromedical transport team in the utilization of rapid sequence induction (RSI) for endotracheal intubation in the prehospital setting. Records of a consecutive series of injured patients undergoing RSI between June 1988 and July 1992 by a university-based aeromedical transport team were reviewed for demographics, intubation mishaps, and pulmonary complications. ⋯ Failure to intubate occurred in three patients (4%). Performed under strict protocol by appropriately trained aeromedical transport personnel, RSI is an effective means to facilitate endotracheal intubation in the injured patient requiring definitive airway control. Pulmonary complications were related to injury severity and not to intubation mishaps.

Review Case Reports
Fatal colchicine overdose: report of a case and review of the literature.
Colchicine poisoning is an uncommon, but potentially life-threatening, toxicologic emergency. A case is reported of a 21-year-old woman who presented to the emergency department approximately 1 hour after ingesting 30 mg of colchicine in a suicide attempt. ⋯ Despite aggressive medical management, the patient suffered a cardiac arrest and died 8 days after the ingestion. The clinical features of colchicine poisoning are highlighted and current therapeutic options are discussed.

Immediate cardiac arrest may occur as a result of the physiological consequences of critical airway management, which may include one or all of the following: (1) sedation and/or paralysis, (2) tracheal intubation, and (3) positive pressure ventilation. Two patients are reported, both with myocarditis, who developed cardiac arrest within minutes of simple intubations. Their arrests were not related to technical difficulties of critical airway management. ⋯ This may be a significant mechanism through which immediate decompensation occurs. Potential conditions that cause preload-dependent cardiovascular systems, as well as alternate therapeutic considerations, are outlined. In these patients intubations should not be delayed, but should be done with extreme caution in anticipation of possible cardiac arrest.
