Haemodynamic pressor response to airway instrumentation is a dangerous complication of general anesthesia.(1) Laryngoscopy and tracheal intubation are associated with cardiovascular changes and increased circulating plasma catecholamines.(2-7) Haemodynamic changes are usually transient and without sequela.(8) Patients with pre-existing coronary artery disease, hypertension or cerebrovascular disease, these changes may causes myocardial ischemia, arrhythmias, myocardial infarction and cerebral haemorrhage.(7, 9, 10)
There are many techniques that have been studied to prevent the hemodynamic response to laryngoscopy and tracheal intubation, which include avoiding cholinergic medications, deepening of anesthesia, pretreatment with nitroglycerine,
