Abstract

Background: Hospitals are faced with increasingly resistant strains of micro-organisms. When it comes to disinfection,
individual parts of electronic equipment of angiology diagnostics such as patient couches of computer tomography (CT) and
magnetic resonance imaging (MRI) scanners prove to be very hard to disinfect. Disinfectants of choice are therefore expected
to possess properties such as rapid, residue-free action without any damaging effect on the sensitive electronic equipment. This
paper discusses the use of the neutral electrolyzed oxidizing water (EOW) as a biocide for the disinfection of diagnostic rooms
and equipment.
Methods: The CT and MRI rooms were aerosolized with EOW using aerosolization device. The presence of micro-organisms
before and after the aerosolization was recorded with the help of sedimentation and cyclone air sampling. Total body count
(TBC) was evaluated in absolute and log values.
Results: The number of micro-organisms in hospital rooms was low as expected. Nevertheless, a possible TBC reduction
between 78.99–92.50% or 50.50–70.60% in log values was recorded.
Conclusions: The research has shown that the use of EOW for the air and hard surface disinfection can considerably reduce
the presence of micro-organisms and consequently the possibility of hospital infections. It has also demonstrated that the
sedimentation procedure is insufficient for the TBC determination. The use of Biocide aerosolization proved to be efficient and
safe in all applied ways. Also, no eventual damage to exposed devices or staff was recorded.
