dental anesthesia

Dental procedures are generally safe; however, transient bradycardia (TB), a temporary slowing of the heart rate, can sometimes occur during local anesthesia administration under sedation. This phenomenon, often linked to the trigeminal cardiac reflex (TCR), can occur during the administration of local anesthesia, particularly in patients undergoing sedation. Understanding the Mechanisms The TCR is a physiological response triggered by stimulation of the trigeminal nerve, which innervates the face and oral cavity. This stimulation can lead to a cascade of events, including a sudden decrease in heart rate and blood pressure, as well as other autonomic responses. Identifying Risk Factors A recent prospective study identified several key risk factors associated with the occurrence of TB during dental anesthesia: Study Findings A study appearing in BMC Oral Health titled “Transient bradycardia during local anaesthesia to the oral cavity under intravenous sedation and … Read more
