Classically described antimuscarinic poisoning signs and symptoms include mydriasis, decreased secretions, ileus, urinary retention, hyperthermia, tachycardia, and altered mental status. These features may be used clinically to assist in the diagnosis of patients with unknown poisonings. We sought to analyze the prevalence of antimuscarinic physical examination findings in evaluating patients presenting with acute poisoning from antimuscarinic agents. ⋯ At least one of these three signs was documented in 94% of our patients. The combination of tachycardia and decreased secretions was the most common pair of findings, recorded in 55.4% of cases. We conclude that the clinical presentation of antimuscarinic syndrome is variable.

This article reviews the empirical literature on patient satisfaction in the Emergency Department (ED). It explores the implications for clinical practice, discusses limitations and weaknesses of the literature, and provides direction for future research. Articles resulting from a comprehensive electronic search were obtained, their references examined, and all other relevant articles not already discovered via the electronic search were acquired and reviewed. ⋯ Promising interventions include: providing information on how the ED functions through visual media, improving ED processes through performance improvement methodologies, and improving the interpersonal skills of providers. Interventions designed to reduce actual waiting times have not been sufficiently studied, but results from several well-designed studies suggest that such a strategy is unlikely to have as great an impact as those targeting perceived waiting times. To advance this area of research, investigators must use: 1) larger, more representative samples; 2) reliable and valid assessment instruments; 3) theory-driven hypothesis testing; and 4) randomized, controlled trials.

In 2000, a series of cases of necrotizing fasciitis (NF) among injection users of black tar heroin was observed in our Emergency Department (ED). The description of these cases characterizes the ED presentation of NF, focusing on the sensitivity of physical signs and ED diagnostic tests. All cases of pathologically determined NF in 2000 were prospectively and retrospectively identified and analyzed. ⋯ Thirty-seven percent of blood cultures and 75% of surgical wound cultures were positive, revealing a variety of organisms. Although tachycardia, leukocytosis, and elevated lactate levels are common in NF patients, fever and soft tissue gas are not. Tests and traditional teaching regarding the "classic" findings of NF should be amended to reflect differences seen in the setting of injection drug use with black tar heroin.

This case report illustrates an adult presenting with the simultaneous occurrence of both methemoglobinemia (MetHb) and systemic toxicity from the topical application of local anesthetics while undergoing laser epilation therapy of the legs. The concurrent development of both is considered uncommon in this setting and may have been related to several factors, including her recent previous treatment, increased absorption secondary to abraded skin with the addition of occlusive dressing, and possible alteration of protein binding and drug metabolism due to the use of medications. The clinical manifestations and mechanisms of MetHb and systemic local anesthetic toxicity are discussed.

Randomized Controlled Trial Comparative Study Clinical Trial
Insertion of the LMA-Unique with and without digital intraoral manipulation by inexperienced personnel after manikin-only training.
In a randomized, crossover study, we compared insertion of the LMA-Unique with and without digital intraoral manipulation by inexperienced personnel after manikin-only training. Ten registered nurses with no hands-on clinical experience of airway management and 100 anesthetized, paralyzed adults (ASA Status 1-2, aged 18-80 years) participated in the trial. Training comprised: 1) a 30-min didactic lecture; 2) a 3-min description of each of the insertion techniques; 3) a 3-min demonstration of each technique using a manikin; 4) 10 min of supervised training on the manikin with each technique. ⋯ There were no differences in performance among nurses. We conclude that insertion of the LMA-Unique is equally successful with or without digital intraoral manipulation by inexperienced personnel in paralyzed adults after manikin-only training. Successful insertion of the LMA-Unique does not require insertion of the finger into the patient's mouth.
