There are microbial risks associated with catheterisation and there has been a long running debate as to whether simple skin cleaning or the use of an antimicrobial is the most effective method. The concern is with reducing the risk of CAUTIs (catheter urinary tract infections). One risk is that bacteria can colonise a catheter and form biofilms, which involve clusters of cells covered in a protective matrix of polysaccharide polymers.
The purpose of urinary catheterisation is to drain urine from the bladder into a collection device, such as a catheter bag. The catheter itself comprises a flexible tube, usually manufactured from silicone, which is inserted through the urethra or sometimes via an abdominal incision (suprapubic catheterisation).
In an article for Inside Hospitals, Dr. Tim Sandle has presented a study looking at the efficacy of an antimicrobial cleaning solution prepared from octendine dihydrochloride. The study looked at the ability of the solution to reduce levels of bacteria on human skin.
