Abstract (english)
Even though ozone has shown its potential for air disinfection in hospital environment, its more frequent use has earned attention only with the COVID-19 pandemic due to its proven antimicrobial effect and low cost of production. The aim of this study was to determine its antimicrobial efficiency against the most common bacterial species in a real-life setting, that is, in the air of one postoperative room of the General Hospital Dr Ivo Pedišić (Sisak, Croatia). Air was sampled for aiborne bacteria before and after treatment with the ozone concentration of 15.71 mg/m3 for one hour. The most dominant Gram-positive bacteria of the genera Micrococcus, Staphylococcus, and Bacillus were reduced by 33 %, 58 %, and 61 %, respectively. The genus Micrococcus proved to be the most resistant. Considering our findings, we recommend longer air treatment with higher ozone concentrations in combination with mechanical cleaning and frequent ventilation.
Abstract (croatian)
Bolničke infekcije mogu se prenijeti zrakom pa je higijena zraka u bolničkim sobama važan preventivni čimbenik. Standardne metode dezinfekcije nisu dovoljne za potpuno uništavanje bakterija u zraku te je potrebno pronaći odgovarajuću metodu dezinfekcije zraka. Primjena plinovitih dezinficijensa pokazala se učinkovitom, a ozon je potencijalni kandidat za dezinfekciju zraka u bolničkom okružju zbog dokazanog antimikrobnog učinka i niske cijene proizvodnje. Svrha ovog istraživanja bila je utvrditi antimikrobni učinak plinovitog ozona na kakvoću zraka bolničke sobe i identificirati standardne bakterije, raspršene u zraku. Istraživanje je provedeno u bolničkoj sobi Opće bolnice “Dr. Ivo Pedišić” u Sisku. Zrak je bio uzorkovan na različitim mjestima u prostoriji prije i nakon tretmana ozonom u trajanju od 1 sata / 15, 71 mg/m3. Nadalje, identifikacija i kvantifikacija vrsta bakterija provedena je u uzorkovanom zraku na različitim lokacijama. Dominirale su gram-pozitivne bakterije iz rodova Micrococcus, Staphylococcus i Bacillus. Nakon tretmana, broj bakterija u zraku smanjen je 33 %, 58 % i 61 %, ovisno o lokaciji uzorkovanja, a najotpornijima su se pokazale bakterije iz roda Micrococcus. Plinoviti ozon prouzročuje značajno smanjenje mikroorganizama koji su raspršeni u zraku u česticama prašine i kapljicama u bolničkoj sobi. Preporučuje se produljeno djelovanje s većim koncentracijama ozona u kombinaciji s mehaničkim čišćenjem i čestim prozračivanjem.
