ABSTRACT
Purpose: To evaluate whether there is any effect of different local anaesthetic agents on hearing loss after spinal anaesthesia.
Methods: Thirty American Society of Anesthesiologists (ASA) I patients without a hearing problem were included in the study. Transient evoked otoacoustic emissions (TEOAE) were examined. Patients were randomly separated into two groups: Group L, 15 mg isobaric levobupivacaine application and Group B, 15 mg isobaric bupivacaine application for spinal anaesthesia. Otoacoustic emission measurements were repeated on patients at the 24th hour after spinal anaesthesia application.
Results: No significant difference was found in the output values of right and left ears according to the input values in group L at no kHz (p > 0.05). No significant difference was found in the output values of right and left ears according to the input values in other kHz of group B (p > 0.05).
Conclusion: Fifteen milligrammes of isobaric bupivacaine and levobupivacaine had no significant difference on the effect of hearing loss after spinal anaesthesia. However, hear loss after spinal anaesthesia has many unknown issues, deserves to be explained more widely by performing many studies.
