Study on the effects of germicide solution soaking the operative washing brush

Taking the residuary on brushes without soaking germicide solution at 5 operative rooms at surgical department, Saint Paul Hospital, Ha Noi. The number of studied brushes was 216, of residuary was 348. Before soaking into germicide solution, 100% washing brushes of A operative room and general operative room all had pathogenic bacteria, among which aerobic bacterium accounted for high rate (35.5%). The antiseptic effect of permanganate 1‰ and chloramine 5% by the time 5, 10, 15, 30, 45 and 60 minutes was similar. But at the time of 2 minutes the effect of permanganate 1‰ was better than chloramine 5%.

Determication of antibiotic sensitivity of E.Coli with AFA gen in urinary system and bile tract system of surgery infection

An analysis was conducted at some big Hospital in Ha Noi on 60 species of E.coli isolated from intestinal fluid and urine of the patients infected in bile duct and urological tract. Results showed that E.coli strains with or without afa gene causing infection of bile duct were rather resistant highly to ampicillin, and chloramphenicol, but sensitive to amikacin, cefataemi, norfloxacin. These E.coli infecting to urological tract and was resistant highly to ampicillin and chloramphenicol. Particulary, E.coli without afagene was resistant co-trimoxazole with higher percentage (72,7-58,3%).

The bacterium causing nosocomial infection in Hospital Dong Da, Ha Noi

From December 1999 to April 2001, a survey performed in Dong Da Hospital (Ha Noi) showed that in aseptic operation room, asmosphere met 90% of the standard criterion, and in ordinary operation room 80%. In post operation rooms and resuscitation room high possibility of microbiological pollution was noted. 10 examinations showed the number of anaerobic bacteria on 1m3 of air is over the permissible criterion. In 2 operating rooms and post operative room, 100% of intact surgical instruments draining tubes and perfusion tubes are met the demand, while aspirators and rolling cars are polluted. 11 on 30 patients (36.7%) had any bacteria in the operated lesion. There is some rate of pollution in the cloths and the fingers of patients (33.3% and 26.7% respectively) and there is some rate of bacterial infested in the skin area of infection and installation of drain (10% and 20% respectively)

Bacteriology and some factors influencing to V.A children in maternal preschool institutions and kindergartens at Hanoi suburban districts, year 2001

96 under 6-year-old children in Tu Liem and Gia Lam districts Hanoi were diagnosed as tracheal V.A. V.A children with pathogene bacteria make up a high rate, especially in the age 4-6. The common pathogene microorganisms in V.A children are H.influenzae, S. pneumoniae, S.pyogenes and S.aureus, among them the most common are H. influenza and S. pneumonia. A high rate of bacterial strains was sensitive experimentally to antibiotics, especially to norfloxacin. Antibiotic resistance to ampicillin, bactrim, chloramphenicol and erthromycine was reported. Most VA children are living in the house holds using charcoal, petroleum for cooking, and living with smoker parents

Study on some changes of paraclinical features of Dengue fever/ Dengue hemorragic fever

At the Department of Communicabe Disease of Ha Noi – Dong Da Hospital 546 patients (52 dengue fever (DF) patients and 44 dengue hemorrhagic fever (DHF) patients were studied. IgM antibody was quantified by ELISA, blood count by 680 plus device. Results: a leucopenia (<4000) 24.2% in DF and 15.9% in DHF. Thrombocytopenia 51.2% in DF. In DF, 81.8% exerted an antibody response; in DHF there were a high rate of stimulating lympho cells (84.1%), there is 100% correlation between stimulating lympho cell and IgM antibody response

Study on antibiotic susceptibility of Neisseria gonorrhoeae

From Nov. 1999 to April 2000, at Ha Noi Centre of Vereno-Dermatology, 365 samples isolated from patients of all ranges of age were studied, using the procedures of antibiogramme to determine the sensitivity of antibiotics to blennorrhagic agent. Results: 65 positive cases (17.8%), among them patients aged 16-40 account for highest positive rate (27.3%). Gonococcus has relatively high resistance to Penicillin (75.4%), then tetracyclin (21.5%), ciprofloxacin (6.2%). The resistance to Kanamycin (18.5%), Nalidizic acide (10.8%), Chloramphenicol (7.7%), Erythromycine (1.5%) were recorded. Multiresistance to 2 antibiotics had the highest rate: PG-TE (16.9%), PG-KA (15.4%), to 3 antibiotics PG-KA-NA (4.6%) was noted. There is no resistance to Ceftriaxon, Spectinomycin, Cephalexin
