Noise-induced hearing loss in orthopaedic staff.
In the light of EEC proposals on the avoidance of damage to hearing caused by noise, a study was undertaken to determine the risk posed by powered orthopaedic instruments. The noise levels from a number of air-powered and electric tools were measured and analysed and found to exceed the recommended levels. The predicted daily personal noise exposure was calculated and the potential for hearing damage confirmed. Twenty-seven senior orthopaedic staff were then assessed by audiometry; evidence of noise-induced hearing loss was found in half the subjects. The increasing use of powered instruments in elective orthopaedics and fracture fixation may present a significant cumulative risk to the hearing of orthopaedic surgeons and theatre personnel. The use of ear defenders should be promoted, and manufacturers should be encouraged to develop instruments with lower noise emission levels.
Objective(s): Noise-induced hearing loss (NIHL) is the major cause of acquired hearing loss. Celecoxib, a cyclooxygenase-2 (COX-2) inhibitor, is a non- steroidal anti- inflammatory drug (NSAID) with known antioxidant and antineoplastic activity. Therefore, we monitored the extent of temporary noise- induced threshold shifts (TTS) and cochlear damage caused by high level 4- kHz noise exposure t...متن کامل
Introduction: It has been shown that low levels of pigmentation increase susceptibility to noise-induced hearing loss in humans. For this reason, white populations develop more pronounced noise- induced hearing loss in comparison to black populations. Similarly, blue-eyed individuals exhibit greater temporary threshold shift than brown-eyed subjects; still, no strong correlation has been veri...متن کامل
Preconditioning by the inhalation of pure oxygen protects rat’s cochlear function against noise-induced hearing loss
Background: Occupational noise-induced hearing loss (ONIHL) is a hearing disorder that affects workers all over the world. Preconditioning with several mild or less potent stressors will effectively prevent the development of noise-induced hearing loss. This study investigated the possible preventive effects of normobaric hyperoxia preconditioning on preventing the noise-induced hearing impairm...متن کامل
Introduction: Nowadays, noise exposure is one of the most important industrial health problems. Noise exposure can cause hearing loss and many other health problems. So, paying attention to the noise exposure problem should be of main priority in industrial health programs. This study was conducted in an oil producing region, aimed to assess noise pollution and noise induced hearing loss. Met...متن کامل
Effects of Exposure to Impact Noise on the Hearing of Armed Forces and Evaluation of the Methods to Control and Decrease its Consequences: A Review Study
Background and Aim: Exposure to impact noise (short-term, high intensity) higher than permitted levels results in injury to the auditory system. Armed forces are one of the occupational groups exposed to these types of noises resulting from gunshots. In this study, relevant articles and research on the adverse effects of impact noise, hearing loss, and tinnitus in armed forces and effective con...متن کامل
