Overview
The LF-PODD study investigates the use of UVC (270nm) light in the prevention of surgical wound infections. Three devices are used in the study, two of which are actively producing UVC light (265 and 275 nm) and one device does not produce UVC light at all. The devices are outwardly completely identical and the devices are drawn for the research participants. Volunteers for neurosurgical procedures are selected for the study. Everyone participating in the study will be informed about the research and written consent will be requested. In the study, UVC light is focused on the surgical area at the beginning of the neurosurgical operation, during the operation, the device automatically dispenses UVC light into the air of the surgical area every 20 minutes, and at the end of the surgical procedure, the device delivers a single dose of UVC light to the surgical wound after closing the surgical wound. Study participants are monitored according to the standard treatment protocol and, in particular, the inflammation of the surgical wound is monitored. The results of the study are recorded and analysed using statistical methods.
