“…Hearing loss following general surgery under general anesthesia without extracorporal circulation has also been reported [8,9,11,18]. The cause is not known, but the etiology in these cases has been suggested to be microemboli or cochlear membrane breaks with perilymph fistulas due to increased middle ear pressure resulting from the use of nitrous oxide.…”

Hearing loss (HL) is a rare complication following cardiac surgery with extracorporal circulation (CSWEC) or other non-otologic surgery under general anesthesia, as is HL caused by loss of cerebrospinal fluid during neurosurgery or spinal anesthesia. The incidence of HL after CSWEC is not known since preoperative hearing testing is not commonly done and a perioperative HL may occur unnoticed. We present four cases of profound sensorineural hearing loss following CSWEC for coronary artery bypass or cardiac valve surgery. The hearing loss was noticed immediately on waking from anesthesia in three of the patients, whereas the fourth patient noticed decreased hearing during the first postoperative week. In all patients audiological investigation suggested a cochlear etiology of the HL. The possible mechanisms for HL are discussed. HL after CSWEC is most likely caused by a microembolism generated by atheromatous material.

“…The characteristics of permanent hearing loss, as well as the technical equipments for improving the extracorporeal circulation might significantly decrease the impairment, and could support the etiology [7][8][9] . However, there has been more and more reports on the hearing loss after a non-extracorporeal circulation or a non-aural operation anesthesia for the past several years, and a considerable quantity of patients failed to completely recover their acoustic sensitivity [10][11][12] .…”

The possible mechanism of inhalation anesthetics on the internal auditory impairment of the rat was investigated by determining the effect of nitrous oxide (N(2)O) and isoflurane on the total RNA yield from the cochlea of the rats. Thirty healthy Wistar rats were randomly divided into 3 groups: group C (control group, n=10) with a 3-h unremitting inhalation of 50% O(2), group N (experiment group, n=10) with a continuous inhalation of 50% N(2)O+50% O(2) for 3 h, and group I (experiment group, n=10) with a 3-h sustained inhalation of 2.5% isoflurane. The TRIzol in combination with RNeasy was used to respectively extract the total RNA from cochlea of rats in the 3 groups. Spectrophotometry was used to detect total RNA yield and electrophoresis to detect the quality. The total RNA extracted from the cochlea of the rats in the groups C and N was 7.69 and 6.51 microg, respectively. There was a 15% decrease in the N group as compared with group C. The total RNA from the rats in the group I was 7.32 microg, and there was hardly any change in the group as compared with the group C. The value of A(260)/A(280) in groups C, N and I was 2.07, 2.04 and 2.04, respectively, showing a very high RNA purity. The result of gel electrophoresis suggested that there was no degradation in the total RNA. It was suggested that the interference of N(2)O on the cochlear RNA yield might be one of the reasons which cause an injury of the ear. The isoflurane shows no harm on the hearing.

“…1,2 Hearing loss during or after cardiac surgical procedures was reported in the early 1980s. 4,24,25 Although use of the cardiopulmonary bypass pump revolutionized cardiac surgical procedures, the machine's high association with micro-emboli could result in intraoperative and postoperative complications, including SNHL. SNHL also has been reported after surgical procedures where spinal and general anesthesia were used for noncardiac/non-otologic procedures.…”
