Of 16 different anaesthetic drugs, the maximum amount of wastage after loaded in syringes but not used, partially unused in ampoules or vials per case basis were seen in propofol, tramadol, and diclofenac (23.72 mg, 18 mg, and 10.6 mg, respectively). A total of 1967.8 Ethiopian birr (89.44 USD) were the cost of wasted drugs, of these the cost of wasted bupivacaine was maximum (33.8%).
Conclusion: There was a significant amount of anaesthetic drugs and financial wastage during perioperative anaesthetic management for different surgical procedure. The use of drugs like neostigmine, metoclopramide, cimetidine and acetaminophen was best practice of usage during the study period no wastage was seen in those drugs. The use of fentanyl was also good which is 3.7% compared to other drugs.
