Ultraviolet light in the orthopaedic operating theatre

Area of Science:

• Microbiology and Hospital Infection Control
• Environmental Health Engineering
• Clinical Research and Orthopaedic Surgery

Background:

• Bacterial contamination in operating theatres poses a significant risk to patients undergoing surgery.
• Total joint replacement procedures are particularly vulnerable to surgical site infections.
• Ultraviolet C (UVC) light is a germicidal agent with potential for environmental disinfection.

Purpose of the Study:

• To investigate the physical and practical aspects of establishing a UVC disinfection system.
• To conduct a clinical trial assessing the efficacy of UVC light in reducing bacterial load.
• To evaluate UVC's impact on airborne bacteria and wound contamination in orthopaedic theatres.

Main Methods:

• Installation of a Ultraviolet C (UVC) system at Winford Orthopaedic Hospital.
• Clinical trial design to measure bacterial load in theatre air and patient wounds.
• Data collection on the effectiveness and challenges of UVC system deployment and operation.

Main Results:

• The study details the successful setup of a UVC system for clinical application.
• Results pertaining to the reduction of bacterial load in theatre air and patient wounds are presented.
• Observed challenges and practical difficulties encountered during the UVC system's use are outlined.

Conclusions:

• Ultraviolet C (UVC) light shows promise in reducing bacterial contamination in surgical environments.
• Practical implementation of UVC systems requires careful planning and consideration of operational challenges.
• Further research is warranted to optimize UVC application in clinical settings for infection prevention.
