Abstract
Laryngoscopy and tracheal intubation in anaesthetized children is often associated with hypertension and tachycardia. This may be the result of reflex sympathetic activation, perhaps involving the baroreceptor system provoked by airway nociceptive stimulus.

Various pharmacological agents have been used to prevent these effects e.g. narcotics, calcium channel blockers, sodium channel blockers, vasodilators, and paracetamol. Because Magnesium can modify many calcium{u2013}mediated responses
