The reflex can be blocked by intravenous injection of an anti-muscarinic acetylcholine (ACh) antagonist, such as atropine or glycopyrrolate. If bradycardia does occur, removal of the stimulus is immediately indicated. This often results in the restoration of normal sinus rhythm of the heart. If not, the use of atropine or glycopyrrolate will usually be successful and permit continuation of the surgical procedure. Caution should be used with fast-push, intravenous opioids and dexmedetomidine which exacerbate the bradycardia. In extreme cases, such as asystole, cardiopulmonary resuscitation may be required.
