Efficacy of IV Lidocaine in attenuating the hemodynamic responses to laryngoscopy and intubation
Aims & Objectives: To determine the efficacy of IV Lidocaine in attenuating the hemodynamic responses to laryngoscopy and intubation and to statistically compare and analyse the results obtained.
Materials & Methods: The study was conducted in 50 ASA I & II patients who were randomly allocated into two groups. Group I patients received IV rocuronium 1.2 mg/kg along with thiopentone induction and the pressor response to laryngoscopy and intubation was assessed at subsequent intervals in the next 10 minutes. Group II patients received IV rocuronium 1.2 mg/kg and IV Lidocaine 1.5 mg/kg along with thiopentone induction and the pressor response to laryngoscopy and intubation was assessed at subsequent intervals in the next 10 minutes.
Results: Lidocaine suppresses the pressor response to laryngoscopy and intubation in the current study.
Conclusion: We found out that intravenous lignocaine is effective to attenuate the pressor response if given along with induction not just before intubation.
