Healthcare Associated Infections

Aseptic Technique and Injecting into Joint Cavities

This resource is part of the intermediate layer of the Scottish Infection Prevention and Control Education Pathway.

Complications associated with injecting into a sterile body cavity are rare, however the consequences of an infection of the joint can cause pain and suffering to the persons we care for, and is costly to the NHS. Providing a standardised approach to aseptic technique with clear indications of what is required, ensure the principles of asepsis are practiced during an invasive procedure.
