Abstract
We analyzed the wasting of drugs in anesthesia subspecialties in our institution for four weeks. Except for cardiac anesthesia, anesthesia was inducted by propofol with vecuronium, and maintained with sevoflurane, N2O in oxygen. Each anesthetist was free to use to anesthetics or other drugs to keep the systemic hemodynamics stable.
The average cost of drug waste was 1,096 yen per case. Propofol was discarded in 169 out of 222 cases, and its mean dose wasted was 88±48 mg. Vecuronium was discarded in 162 out of 222 cases, and its mean dose wasted was 4.5±2.8 mg. Ephedrine was discarded in 156 out of 222 cases, and its mean dose wasted was 34±7mg. Our data showed that anesthetists should be interested in reducing of the amount of drugs wasted during anesthesia.
