Aims and objectives: To Study of the transient hearing loss as a complication of subarachnoid block Material and Method: In the present study 50 subjects were selected who were posted for various surgeries under subarachnoid block. Normal hearing power has been the first precondition for patient selection in study. Preanesthetic examination was conducted in all the study patients. Audiometry was performed in all the patients before surgery. To record the hearing loss audiogram was taken on second and fifth day following surgery in the audiometry room. Results: Majority of the subjects (48%) were in the age group of 21 to 30 years followed by 41-50 years group (22%). 58% subjects were male. The incidence of transient hearing loss was observed in 8% subjects. Post spinal hypotension was observed in 20% subjects whereas Post spinal headache was reported by 14% subject. Out of 4 subjects of transient hearing loss three were male. Three subjects were more than 40 years of age.
