Compare the Effect of Oral Pregabalin versus Oral Clonidine for Attenuation of Hemodynamic Responses for Laryngoscopy and Tracheal Intubation

This study was done to assess the laryngoscopy and intubation responses of two drugs namely, Pregabalin 150mg and Clonidine 0.2mg. The drugs were orally administered 90 minutes prior to induction, as the peak action of both the drugs are known to be 1-2 hours after oral administration. Variation of heart rate changes decreases with increasing age. The selected age range was 18-60 years in our study.
