Contamination of Multiple Dobe Solutions for Injection distilled water and procaine

This study was performed from July to December 1974 to investigate the rates of contamination of distilled water for injection and local anesthetics. 222 vials were sampled from 7 different places of St. Mary's Hospital The samples were cultured for isolation of microorganisms. The results were as follows; 1. Of 222 vials, 11 were Contaminated by 6 types: Staphylococcus epidermis, Bacillus subtilis, Mima polymorph a, Alcaligenes faecalis, Herellea vaginicala and pepto- streptococcus. 2. 5(9.1 %) of 55 vials from surgical wards, 2 (4.2 %) of 48 vials from surgical OPD, and 4 (12,l %) of 33 vials from pediatric wards were contaminated 3. Between rates of contamination of distilled water for injection and local anesthetics and the number of punctures, there was no significant relationship. (CR=1.42 P〉0.1) 4. There was no significant relationship (CR=1.02 P〉0.1) between the rates of contamination of vials and the duration of the first and the last punctures. 5. The ratios of contamination between 75% alcohol and 2% phenol used for disinfection of rubber lids of vials did not show significant difference.
