• There is a potential risk of bacterial and viral infection being transmitted through anaesthesia circuits. Several studies have shown contamination of parts of anaesthetic equipment with bacteria that colonise the mouth and upper airway. A definite relationship between such contaminated anaesthetic equipment and subsequent lung infection remains to be established. Various factors contribute to the transmission and pathogenesis. Among the recommendations for preventing transmission of infection through anaesthetic circuits are using a bacterial/viral filter for every patient or using disposable circuits. Owing to financial constraints, all these recommendations may not be practical in India. Possible guidelines for India may include discarding endotracheal tubes after single use and rigorous cleaning and disinfection of masks and laryngoscopes. Corrugated tubings used in the expiratory limb of the circuit may be washed with soap and water after each patient and dried before use. It is advisable to disinfect all such tubings in 2% glutaraldehyde, and then to wash in water and to dry before use at least once a day or when they are visibly contaminated.
