Drug Audit of Intravenous Anaesthetic Agents in Tertiary Care Hospital

Beauty of the beast: anticholinergic tropane alkaloids in therapeutics

Tropane alkaloids (TAs) are among the most valued chemical compounds known since pre-historic times. Poisonous plants from Solanaceae family (Hyoscyamus niger, Datura, Atropa belladonna, Scopolia lurida, Mandragora officinarum, Duboisia) and Erythroxylaceae (Erythroxylum coca) are rich sources of tropane alkaloids. These compounds possess the anticholinergic properties as they could block the neurotransmitter acetylcholine action in the central and peripheral nervous system by binding at either muscarinic and/or nicotinic receptors. Hence, they are of great clinical importance and are used as antiemetics, anesthetics, antispasmodics, bronchodilator and mydriatics. They also serve as the lead compounds to generate more effective drugs. Due to the important pharmacological action they are listed in the WHO list of essential medicines and are available in market with FDA approval. However, being anticholinergic in action, TA medication are under the suspicion of causing dementia and cognitive decline like other medications with anticholinergic action, interestingly which is incorrect. There are published reviews on chemistry, biosynthesis, pharmacology, safety concerns, biotechnological aspects of TAs but the detailed information on anticholinergic mechanism of action, clinical pharmacology, FDA approval and anticholinergic burden is lacking. Hence the present review tries to fill this lacuna by critically summarizing and discussing the above mentioned aspects.

The Wastage and Economic Effects of Anaesthetic Drugs and Consumables in the Operating Room

Objective

Anaesthesia is a branch in which new anaesthetic drugs, devices, instruments and new treatment methods have been developed. Because of these innovations, health expenditures have escalated. Anaesthetic drugs and consumables constitute the majority of these expenses. Some waste of used drugs and consumables in the operating room is unavoidable. However, excessive drug wastage can be controlled. One of the ways to reduce the financial burden of this wastage is to know the loss cost. This study aimed to discuss the effect of the wastage of drugs and consumables.

Methods

This prospective observational study was conducted in a hospital operating room over a six-week period. At the end of each operation and at the end of each operation day, the amount of wasted and consumables was recorded. The total wastage of the drugs and consumables was calculated by multiplying unit prices.

Results

Data of 363 cases were collected during the study period. The total loss cost calculated during the study period was 2545.77 TL. The highest total loss cost was rocuronium (29.95%) and propofol (27.99%). The least loss was neostigmine (0.06%). The consumption rate of consumables was lower than that of drugs.

Conclusion

A significant amount of drug wastage was recorded during the study period. This can be reduced by simple means. These applications vary from physician behavioural change to the preparation of standard doses of single-dose preparations. Cost training programmes at regular intervals can also be used as a cost-reduction strategy.

Cost drain of anesthesia emergency drugs in a quaternary care hospital

Background:

Anesthesiologists draw up a selection of drugs for emergency use at the start of their list; unused drugs are discarded at the end of the list, to prevent contamination and spread of infections. We audited the practice in our department to evaluate the scale and cost impact of anesthesia emergency drugs wastage.

Subjects and Methods:

A questionnaire was randomly given to anesthesiologists in our department, working in some of the operating rooms in our main floor, every morning over 7 working days. Completed forms were collected at the end of respective lists.

Results:

A total of 93 completed forms were returned. Ephedrine (96%) and phenyepherine (95%) were the most frequently drawn drugs; atropine (96%) and suxamthonium (92%) were the most frequently discarded drugs. Phenylepherine was the single most expensive item wasted, representing 160% of the cost of all other drugs wasted together, and the price of discarded ephedrine and phenylephrine together represented 3/4^th of the total wastage. Some practices carried room for rationalization, such as drawing up of atropine and glycopyrolate simultaneously, of both the vasopressors in patients unsuspected for developing significant hypotension, or of suxamethonium in a patient planned to be intubated and postoperative ventilation.

Conclusion:

Significant savings may be realized through switching to prefilled syringes, making protocols available for rational use of emergency drugs, and safe pooling of expensive drugs between adjacent operating rooms, in an anesthesia department.
