Journal Title: MedPulse -International Medical Journal - Year 2015, Vol 2, Issue 1
Abstract
Introduction: Mild and transient hearing deficiency is not very uncommon after anaesthesia which improves before patient is fully aware of the problem. The hearing loss is either unilateral or bilateral, low frequency and usually reverses spontaneously. Among the various complications an association has been observed transient hearing loss and spinal hypotension. Aims and Objectives: To study the association between temporary hearing loss and hypotension in patients undergoing spinal anesthesia. 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. The hearing loss and hypotension in the subjects was recorded and compared. 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. Among the various complications Post spinal hypotension was observed in 20% subjects whereas Post spinal headache was reported by 14% subject. The incidence of transient hearing loss was observed to be 8%. Out of total 10 cases of spinal hypotension, Transient hearing loss was observed in three cases. On statistical analysis the difference observed in Transient hearing loss and Spinal hypotension was statically significant. Conclusion: Thus we conclude that there is significant association between temporary hearing loss is with hypotension in spinal anesthesia
