The acronym DUMBELS is a mnemonic used primarily in the context of identifying signs and symptoms associated with cholinergic toxicity, particularly from exposure to certain chemicals or drugs that increase acetylcholine activity in the body. Each letter in DUMBELS corresponds to a specific symptom:

  • D: Diarrhea
  • U: Urination
  • M: Miosis (constricted pupils)
  • B: Bradycardia (slowed heart rate)
  • E: Emesis (vomiting)
  • L: Lacrimation (excessive tearing)
  • S: Salivation (excessive saliva production)

Understanding DUMBELS is crucial for emergency medical responders, as recognizing these signs can help in the rapid assessment and treatment of patients who may be experiencing cholinergic toxicity due to poison exposure, certain medications, or nerve agents. This knowledge allows for timely intervention, potentially improving outcomes in critical situations involving such toxic exposures.
