Özet
SEP recordings are elicited from the external stimulation of the peripheral sensorial nerves. In this study, effects of local anaesthetics on SEP of twelve patients in two groups were evaluated by using epidural administration of bupivacaine (n=6) and lidocaine (n=6). In the first group, lidocaine 400 mg, in the second group, bupivacaine 75-100 mg were administered into the epidural space. SEP potentials obtained by electrical stimulation of posterior tibial nerve were recorded before and 15 min, 30 min, 1 h, 2 h, 3 h, 4 h after epidural administration of local anaesthetics. Increase in SEP latency time in lidocaine group began at 15th min. and reached its maximum point at 30th min. In bupivacaine group increase in SEP latency time began at 15th min and reached its maximum point in one hour. There was not any statistically significant decrease in SEP amplitudes in both groups (p>0.05). With data from this study, we conclude that SEP latency time recordings were much more stable than amplitude values.
