Pressure receptors exist within the walls of the carotid bulb which are responsible for maintaining the balance between blood volume, vascular tone, and cardiac output. When these receptors are manipulated during neck surgery the result may be bradycardia, hypotension or cardiac arrythmia. Such events occur sporatically during head and neck surgery and occasionally may prove fatal. While many surgeons advocate anesthetizing the carotid bulb prophylactically, this practice is not universally accepted.
