Brief Summary

- Laryngoscopy prior to intubation and intubation in itself produce significant hemodynamic stress response in the form of tachycardia and hypertensionwhich is usually transient, returns to base line within 10-15 minutes and well tolerated by healthy individuals without cardio-respiratory compromise but can prove disastrous in the patient with cardiac and neurological diseases.

- Among opioids, fentanyl citrate has been identified as a most effective agent for this purpose. Fentanyl is effective in blunting  stress response to intubation and has been used for this purpose in different doses titrationranging from 1.5µg/kg to 6µg/kg in different studies.

- In most of the studies, investigators assessed response of fentanyl in normotensive population to prevent hemodynamic stress response to intubation. Their findings cannot be applied to the hypertensive population which behave quite differently than normotensive group.

- This prompted us to plan the present study to evaluate the efficacy and safety of two different doses of fentanyl (2µg and 3µg) to prevent hemodynamic stress response to laryngoscopy and intubation in controlled hypertensive patients.
