Abstract

Zdravstvene su ustanove u sklopu svoje djelatnosti dužne ne samo liječiti nego i unaprijediti zdravlje svakog čovjeka. Mnoštvo neželjenih situacija u kojima bolesnici mogu postati žrtve može se izbjeći drugačijim pristupom i davanjem veće važnosti poznavanju i provedbi osnovnih načela asepse i antisepse. Sterilizacija je važan korak u protokolu za kontrolu infekcija. Neodgovarajuća sterilizacija je važan uzrok egzogeno stečenih infekcija. Postotci infekcija kirurških rana, različito se, prema mnogim istraživanjima, kreću od manje od 1 do preko 9 na 100 kirurških zahvata. Infekcije kirurških rana su zajedno sa urinarnim i respiratornim infekcijama najčešće infekcije stečene u bolnici. Nekoliko međunarodnih i državnih tijela, kao što je Centar za kontrolu bolesti i prevenciju, Svjetski forum za bolničku sterilizaciju i Hrvatska udruga medicinske sterilizacije, preporučaju redovnu uporabu bioloških indikatora kao alata za kontrolu sterilizacijskih procesa. Biološki indikatori su idealni kontrolori procesa sterilizacije jer za razliku od kemijskih indikatora mjere sterilizacijski ciklus direktno uporabom spora, odnosno njihovim uništenjem. Neučinkovitost sterilizacijskog procesa mogu uzrokovati mnogi problemi kao što su prisutnost zraka, vlažan materijal, neispravan mjerač tlaka, pretrpavanje komore ili nezadovoljavajuće vrijeme same sterilizacije. Ovi problemi mogu nastati zbog kvara na autoklavu ili nedovoljno educiranog osoblja. Za kontrolu parne sterilizacije se koriste spore Geobacillus stearothermophilusa. Redovna uporaba bioloških indikatora doprinosi osiguravanju kvalitetne zdravstvene skrbi i sprječavanju nastanka bolničkih infekcija.

Abstract (english)

Health institutions in the framework of their activities must not only treat, but also improve the health of every man. A multitude of adverse situations in which patients may become victims may be avoided by a different approach and giving more importance to knowledge and implementation of the basic principles of asepsis and antisepsis. Sterilization is an important step in the infection control protocol. Inadequate sterilization is an important cause of exogenously acquired infections. Rates of surgical site infection differ in different studies, varying from less than 1 to over 9 per 100 procedures. Surgical site infections along with urinary tract infections and respiratory tract infections are most commonly encountered hospital aquired infections. Several international and national bodies, like Center for Desease Control and Prevention, World Forum for Hospital Sterile Supply and Croatian Association of Sterilization, have recommended regular use of biological indicators as a process control tool. Biologic indicators are ideal monitors of sterilization process because, unlike chemical indicators, they measure the sterilization process directly by using of spores and their destruction. Ineffectivness of the sterilization process could be caused by many problems such as trapping of air, wet material, faulty pressure gauge, overloading of drums or inadequate holding time. This problems could arise because of faulty autoclaves or inadequately trained stuff. Geobacillus stearothermophilus spores are used for control of the steam sterilization process. Regular use of biologic indicators is contributing to the provision of quality health care and the prevention of the occurence of nosocomial infections.
