Area of Science:

  • Dentistry
  • Emergency Medicine
  • Cardiology

Background:

  • Dental local anesthetics can rarely cause adverse cardiovascular events.
  • Prompt and effective emergency response is vital in managing such incidents.

Observation:

  • A 57-year-old male experienced loss of consciousness post-dental local anesthetic injection.
  • Initial attempts to secure medical assistance were unsuccessful, with delayed ambulance arrival (approx. 35 minutes).

Findings:

  • Electrocardiogram revealed supraventricular tachycardia.
  • Immediate cardioversion successfully converted the rhythm to sinus rhythm, restoring circulation.

Implications:

  • This case highlights critical deficiencies in emergency protocols during dental treatment.
  • Inadequate emergency management can significantly worsen patient outcomes in dental adverse events.
