Status of S.aureas carrying in the surgical patients and the relations between the infection of incision and the existence of S. aureus in the nose

Having studied the results, we realised: -Incidence of nasal S.aureus carriage in the surgical patients is 36.1%, of skin S. aureus carriage is 9.6%. - Incidence of S. aureus infection of incision on patients who carry this microorganism in nose is 8.2% and do not carry it is 2.3%. - S. aureus patient ‘s nasal carriage is really the risk factor for transmission of this microoganism to skin and causing infection of incision, including the clean operations. - Treating infectious locations and resolving state of S. aureus patient’ nasal S. aureus carriage will reduce the infected incisions from endogenous flora.

Antibiotic resistance of some bacteria isolated from infectious lesion of operation at the Hospital No 175

157 samples were isolated from infectious operating lesion they were cultured into Biomerieus culture media and undergone an antibiogramme on Muller-Hilton medium. S. aureus and E. coli are the most common organisms, which are isolated. Occasional infections occurred increasingly.

Study on bactericidal effects of ultraviolet rays in vitro

Having studied in vitro the effect of UVR on the two species of microorganisms which are most common as agents of surgical infection, we realized the closer the distance from the irradiation lamp and the longer the irradiation time, the stronger the bactericidal effect of UVR. When UVR is applied for air disinfection within the distance of more than 2 meters from the sunlamp irradiation, it can also reduce significantly the number of microorganisms in the air. It is due to the fact that there is a continuous air exchange between the upper and the lower part of the room. Previous studies and the experiments on petri dishes show that the use of UVR for cleaning infected wounds and preventing infection is an effective, simple and safe measure
