Study objective: Evaluation of bacterial growth in atropine and glycopyrrolate.
Design: Laboratory investigation.
Subjects and measurements: Standard microbiological methods were used to evaluate the impact of atropine and glycopyrrolate on the growth of Acinetobacter baumannii, Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli. Bacterial count was checked at 0, 1, 2, 3, 4, 6, and 24 hours.
Main results: Atropine or glycopyrrolate did not support the growth of the above bacteria at any examined time at room temperature. Glycopyrrolate killed all of the examined strains (P < .05), whereas in atropine, only the clinical isolates of Staphylococcus and Acinetobacter were killed (P < .05).
Conclusions: Drawing up atropine or glycopyrrolate at the beginning of the operating list and use within 24 hours if needed are a safe practice and do not pose infection hazard. We can also reduce hospital costs if we do not throw away these unused syringes following each case.
