Abstract


Objective: To compare the effects of intratracheal and intravenous lidocaine on bucking, cough and emergence time at the end of anesthesia.
Methodology: Sixty patients were randomly allocated in to 2 groups to receive lidocaine 1.5mg/kg either intravenous or intratracheal in a double-blind study. The number of bucking and coughs for each patient was continuously monitored for thirty minutes after extubation. Heart rate, systolic, and diastolic blood pressures were measured before the injection of test solution and one minute after the tracheal extubation. The emergence time was also recorded.
Results: There was no significant difference in the number of bucking (P=0.192) before extubation and coughs during the 30-min monitoring after extubation (P=0.97) between two groups. The difference in emergence time between two groups was not significant (P=0.715).
Conclusion: The effect of intravenous or intratracheal lidocaine was similar on bucking, cough, and emergence time at the end of general anaesthesia.
