PurposeTo evaluate whether there is any effect of different local anaesthetic agents on hearing loss after spinal anaesthesia.MethodsThirty American Society of Anesthesiologists (ASA) I patients without a hearing problem were included in the study. Transient evoked oto-acoustic 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. Oto-acoustic emission measurements were repeated on patients at the 24th hour after spinal anaesthesia application.ResultsNo significant difference was found in the output values of the 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 the right and left ears according to the input values in any kHz of Group B (p > 0.05).ConclusionFifteen milligrammes of isobaric bupivacaine and levobupivacaine had no significant difference on the effect of hearing loss after spinal anaesthesia. Hearing loss after spinal anaesthesia has many unknown issues, and deserves to be explored by performing many studies.
