Comparison of the effects of %0.5 bupivacaine and %0.5 levobupivacaine used for epidural anesthesia on QT dispersion and haemodynamy [Epi̇dural anestezi̇de %0.5 bupi̇vakai̇n ve %0.5 levobupi̇vakai̇n kullaniminin QT di̇spersi̇yonu ve hemodi̇nami̇k etki̇leri̇ni̇n karşilaştirilmasi]

Objective: the aim of this study was to compare the hemodynamic variables and qt dispersion effects of 05% bupivacaine and 0.5% levobupivacaine using epidural via. methods: sixty patients scheduled for operation under epidural anesthesia were included to this study. the patients were randomized into two groups; 15 ml of 0.5% bupivacaine was given to group b patients (n=30) and 15 ml of 0.5% levobupivacaine was given to group l patients (n=30). systolic blood pressure,diastolic blood pressure,mean blood pressure,heart rate,saturation of peripheral oxygen,respiratory rate and side-effects were recorded during perioperative period. postoperatively,motor blockade recovery time was assessed at 30-minute inten'als and total motor blockade time was recorded. ecg was recorded at preoperatively,at 30 minutes after first epidural anesthetic and postoperatively 24-hour and was assessed by a cardiologist. results: motor blockade and total blockage time were found to be longer in group b (p<0.05). mean blood pressure at the 180th minute was found to be decreased in group b (p<0.05). the longest corrected qt interval and the shortest corrected qt interval were increased in group b (p<0.05). incidence of hypotension was higher in group b (p<0.05). conclusion: levobupivacaine can be preferred to bupivacaine in patients having cardiac problem and when less motor blockade is desired.
