The Prevalence of Bacterial and Red Blood Cell Contamination of Multiple Dose Vials used in ICU, NICU and the Operation Room

Transmission of infection via multiple dose vials has been well documented. Thus, the probability of contamination in these vials, no matter how little, is very important because they are supposed to be a potential source of nosocomial infection in Introduction patients. Therefore, a prevalence study on the contamination of multiple dose vials (MDV) seams to be necessary. The purpose of this study was to identify bacterial contamination and red blood cell (RBC) contamination in multiple dose vials used in Bahman 22nd Hospital.In a cohort study, different types of MDVs used in different sections of Bahman 22nd Hospital were periodically collected Materials during one year. Information about the medication, wards, and labeling of vials, the date and time of opening and storingMethods temperature was recorded. Then, 0.5 ml of each vial was cultured in Blood Agar media at 37°c for 48 hours. Also, the samples were tested for Red Blood Cell contamination after they were centrifuged.Totally, 300 MDVʹs were collected and studied. No bacterial contamination was found in the cultures. Of the 300 vials available, 2 vials were contaminated with RBC (2 RBC in one vial and 3 RBC in another) at a contamination rate of 0.67%.Although the results of bacterial culture of multiple dose vials used in different wards of the hospital were negative, the Conclusion contamination of two vials with Red Blood Cells is still very important. The finding should raise concerns about the potential risk of transmission of blood borne pathogens through such vials.
