Context: Auditory brainstem response is the most important tool in differential diagnosis and degree of hearing impairment. Many studies have been carried out to ascertain the effects of noise on human beings but very less on the transportation workers; hence, considering the need of time and use of brainstem auditory-evoked potentials (BAEP), this study was conducted to analyze the effect of noise pollution on auto-rickshaw drivers (ARDs). Aim: The aim of this study was to evaluate I, II, III, IV, and V wave latencies in ARDs and comparing it with control subjects in Central India. Settings and Design: This was a case-control study done on ARDs as participants and compared it with normal healthy individual BAEP pattern. Materials and Methods: We recorded BAEP from fifty healthy control subjects and fifty ARDs from the community of same sex and geographical setup. The absolute latencies were measured and compared. Recording was done using RMS EMG EP MARK II machine manufactured by RMS recorders and Medicare system, Chandigarh. Statistical Analysis Used: All the data related with subjects were filled in Excel sheet and analyzed with the help of EPI 6.0 info software with Student's t-test. Results: There were prolongations of all absolute wave latencies of II, III, IV, and V in the ARDs as compared to control subjects. Conclusions: The prolongation of all absolute latencies of II, III, IV, and V suggests abnormality in brainstem auditory pathway mainly affecting the retrocochlear pathways in group of ARDs (noise exposure >10 years) than other group who had exposed for <10 years and is more significant on the right ear than left. |
