COMPARATIVE ARRHYTMOGENIC EFFECTS OF LIGNOCAINE AND BUPIVACAINE

evaluate whether lignocaine and bupivacaine caused arrhythmias in ASA I status patients, during spinal anesthesia, by using Holter monitorization and QT dispersion parameters. Methods: Spinal anesthesia was performed at the L3-L4 level. Patients in Group I (n=16) and Group II (n=17) were given 2%, 3ml lignocaine and, 0.5%, 3ml plain bupivacaine respectively. Starting 45 minutes before the operation, 24h Holter ECGs were recorded. Preoperative and postoperative 12 lead ECGs were recorded for QT dispersion measurements which were obtained by a blinded cardiologist. Results: In our study there were no ST segment depressions as an indication of ischemia in Holter recordings and there were no significant differences in both groups (p>0.05). The mean preoperative QT interval dispersion wa
