Role of repeated epidural injections in preventing post-spinal hearing loss

Sudden bilateral hearing loss after spinal anaesthesia

“…More than one entry into the dura with the needle has greater potential for hearing loss than a single entry. 7 The age of the patient is an important factor associated with hearing loss after spinal anaesthesia. 8 Gültekin and Ozcan found that 52 per cent of hearing losses occurred in young patients, compared with 16 per cent in older patients.…”

“…Additional CSF leakage during the process would generate this effect. More than one entry into the dura with the needle has greater potential for hearing loss than a single entry 7 …”

Epidural Volume Extension: A Review

“…Epidural injections of saline and blood are known therapies for post-spinal low-pressure effects such as post-dural puncture headache and hearing loss 44,45 . use of EVE and continued postoperative epidural injections for postoperative analgesia was associated with a decrease in postoperative hearing loss 46 . Whether raising intrathecal pressure with EVE prevents post-spinal low-pressure adverse effects is another area of possible research.…”
