Scopolamine Toxicity in an Elderly Patient.

We present a case of a 66-year-old female who was to undergo a scheduled operation and placed on our institution's ERAS (Enhanced Recovery After Surgery) protocol. The intraoperative course was unremarkable. The patient developed delayed emergence in the Post-Anesthesia Care Unit. On physical exam, the patient was noted to have a transdermal scopolamine patch adjacent to an area of skin breakdown. She also displayed signs of central anti-cholinergic toxicity including mydriasis and tachycardia. Following removal of the scopolamine patch and administration of physostigmine, her mental status returned to baseline. This interesting case highlights the importance of considering patient specific factors such as age when implementing ERAS protocols perioperatively. It also demonstrates the risks associated with scopolamine and the importance of risk/benefit analysis prior to administration.
