“…Thus, the dishwasher method introduced for anaesthetic equipment (Barrow and Meynell, 1966) appears to be acceptable. Furthermore, it saves space, time and money, does not require previous manual washing for the removal of hardened blood and expectorate, and does not entail the disadvantages of autoclaving (Stark, Green and Pask, 1962;Bennett, Cope and Thompson, 1968) or sterilization by ethylene oxide or other disinfectants (Hirose, Goldstein and Dailey, 1963;Marx, 1969;Lipton et al, 1971;Varpella, Otterstrom and Hackman, 1971;Craig et al, 1975;George, 1975;Stetson, Withbourne and Eastman, 1976).…”

The bacterial content of oxygen and nitrous oxide immediately before and after passing through clean and used breathing systems (circuits) was measured using a specially constructed agar chamber (Bourdillon's slit sampler). The content per litre of oxygen from the outlet of the anaesthetic machine was 4.0 X 10-2, and 2.9 X 10-2 for nitrous oxide, corresponding to 3.5 X 10-2 for a 50% mixture of the gases. After passing through cleaned circuits, the bacterial pollution of the gas mixture had increased by 30%, but more than elevenfold after passing through used circuits. The content from cleaned circuits was less than that measured previously in the air of hospital wards and operating theatres, whereas gases from used circuits were polluted to approximately the same extent. It is concluded that used circuits may increase the risk of cross-infection. The cleaning method employed by us (dish-washer--hot airy drying) appeared to be acceptable.

“…We have to think of poor risk patients who need surgery requiring general anesthesia, the hazard of infection due to contamination of anesthetic equipment is a matter of big concern. Anesthetic equipment which directly or indirectly makes contact with the airways of the patient must be decontaminated before reuse [5][6][7] .…”

Background: Anesthetic equipments undeniably occupy prime importance in clinical practice. However, their importance falls into question if they are not appropriately prepared and handled. Objectives: The objective of this audit was to assess the current practice of anesthetic equipment disinfection in comprehensive specialized hospital. Methods: An observational study was conducted. A total of 70 patients were operated during the study period and data was analyzed using Microsoft Excel as well as descriptive statistics was used. Results: Around 94.2% of anesthetists followed only the first step of disinfecting laryngoscope blade and 74.2% of anesthetists stored both the laryngoscope blade and handle appropriately but the rest of the steps were performed poorly and none of the anesthetists applied alcohol for both blade and handle disinfection. All anesthetists immersed the endotracheal tube or laryngeal mask airway in high level disinfection solution and then rinse them with water. However, none of the anesthetists were applied around 6 of the process of disinfecting these equipments. Regarding face mask, only 4 (5.7%) of the anesthetists washed the anesthetic face mask with soap and 2 (2.8%) stored it safely for further use but none of them used alcohol to disinfect this equipment. Conclusions: Even if all of the anesthetic equipments disinfection process needs improvement, special attention should be given to laryngoscope disinfection protocol since this equipment is being used frequently between patients as well as changing the high level disinfectant solution every 24 hours because more than this hour the solution cannot be used as disinfectant and finally we recommend that all anesthetists should follow the standards of anesthetic equipment disinfection process.

“…This method of disinfection has been recommended for all anaesthetic face masks, tubing, rebreathing bags, etc. (Jenkins and Edgar, 1964;Bennett, Cope and Thompson, 1968;Craig et al, 1975). It is essential, however, that the equipment be completely immersed in the water.…”

Decontamination of Anaesthetic Equipment and Ventilators

For some years there has been concern over the role of anaesthetic and ventilatory equipment in the transmission of infection. It is known that those pieces of anaesthetic apparatus which come in direct contact with the skin and mucous membranes of the patient (face mask, airway, endotracheal tube, catheter mounts, suction catheters) are all liable to become contaminated with microorganisms (Stark, Green and Pask, 1962). Jenkins and Edgar (1964) found all the corrugated tubing in one hospital to be contaminated with Pseudomonas pyocyanea, and showed experimentally that a small proportion of these organisms could be caught up in the inspiratory gas. They showed further that coughing into anaesthetic apparatus caused heavy contamination of masks and Y-pieces, and that soda-lime in a Waters' canister was ineffective as a bacterial filter. However, as a result of experimental work, Stark, Green and Pask (1962) concluded that it was unlikely that infection would be transmitted from patient to patient via anaesthetic machines, but did state that if a patient was known to be infected with virulent organisms, then readily sterilizable apparatus should be used. Virtually every organism has been isolated from anaesthetic equipment, and transmission of infection from such apparatus to patient has been confirmed in a number of instances (
