Study of post spinal anesthesia hearing loss:A hospital based study
Journal Title: Medpulse International Journal of Anesthesiology - Year 2017, Vol 2, Issue 2
Abstract
Background: Spinal anaesthesia is one of the most frequent regional anaesthesia techniques in surgical interventions, being used in all procedures below the umbilicus. Hearing loss following spinal anaesthesia is a known yet uncommonly reported complication with incidence between 0.4% and 40%, affecting the low frequency range. Aims and Objective: To study the post spinal anesthesia hearing loss observed in tertiary care institute. Materials and Method: In the present study total 30 cases admitted for various surgeries under spinal anesthesia in the institute were enrolled. Informed written consent was obtained from each patient. Pre-anesthetic examination was done in all the patients. Audiometry was performed in all the patients before surgery in a sound-proof room using Arphi portable audiometer. Post operative hearing loss was recorded on second and fifth day following surgery. The audiogram was repeated after one month of surgery to verify if return to normally of hearing power had occurred. The complications that have occurred had also been recorded. All the findings were recorded on a prestructured proforma. Results: Majority of the patients (40%) under the study were between the age group of 21-30 years followed by 31-40 years of age (26.67%). Majority of the patients were male (60%) and 90% patients were of ASA grade I. Transient hearing loss was diagnosed in 13.33% patients. Post spinal headache was seen in 16.67% patients and post spinal hypotension was seen in 23.33% patients. Two cases were having hearing loss at 2000Hz while at 250Hz and 6000Hz one case each was diagnosed. All the patients were followed for one month and it was observed that the hearing loss was completely revered in one month. Conclusion: Thus we conclude that transient hearing loss was diagnosed in 13.33% patients and it was found that hearing loss was completely reversible.
