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.
