Abstract

Current methods of treatment for retinopathy of prematurity, using laser photocoagulation, require surgeons to assume awkward standing positions, which can result in occupational injury. A new infant surgical table was designed for improving this surgical procedure. To quantify its benefits, an ergonomic comparison of the standard and modified procedures was carried out, using specialized checklists, Nordic Musculoskeletal Questionnaires, and analysis of videotaped procedures using an Ovako Working Posture Analysing System method. Analysis of the typical laser photocoagulation procedure revealed a high risk for cumulative trauma disorders. The majority of the risk factors were lowered considerably with use of the new table. Improvement was largely due to the new table allowing seated postures during surgery, relieving muscular stress on the back, shoulders and legs. This study demonstrates risk reduction through engineering design of new medical devices, and illustrates how combining different assessment approaches can help evaluate ergonomic impact of medical technologies.
