Ultraviolet radiation and air contamination during total hip replacement

Research output: Contribution to journalArticlepeer-review


Ultraviolet (uv) radiation of the operating room was assessed bacteriologically in an open randomized study of 30 total hip procedures. Volumetric air-sampling demonstrated that the number of colony forming units (cfu m-3) were significantly reduced (P less than 0.001) by uv light, both close to the wound and in the periphery of the operating room. No adverse effects of the uv-irradiation were observed either in the patients or the staff. In operating rooms fitted with a 'zonal ventilation' system and with an air change rate of about 70 h-1, the addition of uv irradiation during surgery may achieve 'ultra clean' air. However, in conventionally ventilated operating rooms uv-irradiation alone is probably not sufficient to do so.
