Observational Study
Microbial stability of syringes of anesthetic drugs prepared in the operating room.
To determine whether microbial contamination of anesthesia syringes prepared in the operating room (OR) become contaminated in a time-dependent fashion. ⋯ Contamination of anesthesia syringes is uncommon and occurs at a low overall concentration of bacteria. Contamination does not appear to be time related, and thus calls into question the reasonableness of USP Chapter 797's one-hour requirement.
