Local Anesthetic Systemic Toxicity

A femoral nerve block has just been performed on a 65-year-old male who sustained a right femoral neck fracture. The patient also sustained a laceration to the scalp which was repaired by the medical student. The patient is now complaining of blurry vision, paresthesias, and “twitchiness”. The patient progresses on to seizure followed by cardiac arrest and will need high quality ACLS care along with lipid emulsion therapy.

Toxic Alcohol Ingestion

A 46 year-old male presents with a GCS of 3 after being found in the back alley behind a drug store. The team will need to work through a broad differential diagnosis and recognize the need to intubate the patient. If they try naloxone, it will have no effect. After intubation, the team will receive critical VBG results showing a profound metabolic acidosis with a significant anion gap. The goal is to trigger the team to work through the possible causes of an elevated anion gap, including toxic alcohols.
