The intent of this research was to address the following question: Will an alteration in the drug aspiration technique cause a significant difference in the incidence of multidose vial contamination? The control group consisted of multidose vials collected at the end of each day from staff anesthetists. The use of these vials reflected the practice technique of a single needle and syringe for each vial. The vial, as well as needle and syringe, were used on all cases managed for the day. ⋯ Of the 369 multidose vials, one tested guaiac positive, 0.27%. A chi-square test on the cumulative data demonstrated a significant (p less than .05) difference between the two groups. The research demonstrated that occult blood may be contained within the used multidose vials suggesting that contaminated drug may then be injected into another patient.(ABSTRACT TRUNCATED AT 250 WORDS)
