Summary

Interscalene brachial plexus block (IBPB) may cause temporary hearing loss in the same ear. This auditory dysfunction, observed in some patients, might be linked to sympathetic nerve effects.

Area of Science:

  • Anesthesiology
  • Audiology
  • Neurology

Background:

  • Interscalene brachial plexus block (IBPB) is a common regional anesthesia technique for shoulder surgery.
  • Potential side effects of IBPB, particularly auditory changes, require further investigation.

Purpose of the Study:

  • To investigate the incidence and characteristics of auditory dysfunction following interscalene brachial plexus block.

Main Methods:

  • Audiometric threshold measurements (0.25-18 kHz) were conducted before IBPB, 2-6 hours post-surgery, and on the first postoperative day in 20 patients.
  • Patients received bupivacaine 0.75% with adrenaline followed by a 24-hour continuous infusion of 0.25% bupivacaine.

Main Results:

  • Four patients exhibited hearing impairment on the side of the block post-operation.

  • Impairment was noted on the day of surgery in three patients and the following day in one.
  • Maximum threshold change was 35 dB at 6 kHz; one patient also showed contralateral hearing changes.

    • Conclusions:

    • Interscalene brachial plexus block may induce transient auditory dysfunction in the ipsilateral ear.
    • The mechanism may involve an effect on sympathetic innervation, warranting further research into anesthetic-related ototoxicity.
