Abstract
presence of vital neural structures located there as well as exit/ entry foramina for cranial nerves and blood vessels poses a great challenge to the neurosurgeon who must do all possible to preserve this structures during neurosurgical intervention and as well as the neuroanaesthetist who had to continuously monitored neurovital signs which guide the surgeon in view of structure such as the brainstem which controls cardiorespiratory activities located in the skull base. These vital structures regulate the dynamic body reflexes (cardiorespiratory center) and cranial nerves important for control of body function. The trigeminal nerve, which is the largest cranial nerve with mainly sensory supply to the craniofacial structure is involved in the trigeminocardiac reflex. Trigeminocardiac reflex is a well know entity consisting of bradycardia, arterial hypotension, apnea and gastric hypermotility [1]. In skull base surgeries, awareness of a rapid drop in pulse rate, mean arterial pressure more than 20% of baseline values following stimulation of the peripheral or central branches of trigeminal nerves or the structure
it supplies should be recognized [1-3] and could avert calamity
