Case Reports
Oral and Transdermal Rivastigmine for the Treatment of Anticholinergic Delirium: A Case Report.
Anticholinergic toxicity is a common cause of delirium in emergency department patients. The standard antidotal treatment for anticholinergic toxicity is physostigmine. Physostigmine functions as a reversible acetylcholinesterase inhibitor that readily crosses the blood-brain barrier. Rivastigmine is another member of this class currently approved for the treatment of Alzheimer's disease and Parkinson's disease. Rivastigmine also crosses the blood-brain barrier and has been found to be effective in the management of anticholinergic toxicity in limited case reports. ⋯ A 61-year-old women presented to the emergency department via emergency medical services with altered mental status and a Glasgow Coma Scale score of 8 out of 15. She was found down near multiple medication bottles, including diphenhydramine and dicyclomine. Her physical examination was consistent with anticholinergic toxicity with mydriasis, obtundation, and warm flushed skin. In addition to standard resuscitation, she received two doses of rivastigmine 3 mg via nasogastric tube. After the second dose she was alert and oriented. She was admitted to the intensive care unit and had a rivastigmine patch applied. She was deemed back to her baseline 27 h after presentation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although the standard antidotal treatment for anticholinergic toxicity is physostigmine, there is a national shortage of this medication. In the absence of this standard antidote, it is reasonable for emergency physicians to use rivastigmine as an alternative treatment. This can be delivered orally or via nasogastric tube with dosing each hour until resolution of symptoms. Alternatively, in consultation with toxicology, it may be reasonable to use transdermal rivastigmine, as it provides consistent drug absorption for 24 h.

Patients with limited English proficiency (LEP) have been shown to experience disparities in emergency department (ED) care. The objectives of this study were to examine the associations between LEP and irregular ED departures and return ED visits. ⋯ After multivariable adjustment, we did not find an increased frequency of irregular ED departures or 72-h or 7-day returns among patients with LEP compared with people proficient in English. However, we did find that higher proportions of patients with LEP were admitted to the hospital at the time of the return ED visit.

Procedural sedation is commonly practiced by emergency physicians to facilitate patient care in the emergency department (ED). Although various guidelines have modernized our approach to procedural sedation, many procedural sedation guidelines and practices still often require that patients be discharged into the care of a responsible adult. ⋯ There is no pharmacodynamic or pharmacokinetic basis to require discharge in the care of a responsible adult after procedural sedation. Thoughtful medication selection and the use of evidence-based pre- and postprocedure protocols in the ED can help circumvent this requirement, which likely disproportionally impacts patients who are of low socioeconomic status or undomiciled.
