Randomized Controlled Trial Comparative Study
Comparison of injection lignocaine (preservative free) 1.5 mg/kg i.v with oral pregabalin 150 mg for attenuation haemodynamic response to laryngoscopy and tracheal intubation.
Endotracheal intubation is sine quo non for safe conduct of general anaesthesia. Pregabalin, an anticonvulsant drug is being studied for control of haemodynamic response to laryngoscopy and intubation. Some authors have found that pregabalin 150 mg orally attenuates the haemodynamic response to laryngoscopy. ⋯ Pregabalin was more effective than lignocaine in controlling diastolic blood pressure at 1, 3 and 5 minutes following laryngoscopy, and mean arterial pressure at land 3 minutes following laryngoscopy. There was no difference between two groups when systolic BP and rate pressure product were compared. Lignocaine (preservative free) thus, exerts better control over heart rate and pregabalin exerts better control over diastolic and mean blood pressure following laryngoscopy.
