Abstract:Conductive rubber anaesthetic circuit tubing both absorbs volatile agents and leaks these agents through its walls. We quantified the leakage and absorption properties of the most commonly used plastic materials used to make breathing circuit tubing, relative to conductive rubber. We then compared two different types of plastic tubes used to carry gas to volatile agent monitors; one made of polyvinyl chloride, the other made of polyvinyl chloride lined internally with a thin layer of polyethylene. We found that the three commonly used plastic types used to make anaesthetic circuit tubing all leak less volatile anaesthetic through their walls than conductive rubber. Polyethylene and polypropylene tubing absorb significantly less volatile anaesthetic than conductive rubber; however, this is not the case with polyvinyl chloride tubing. Differences in the leakage and absorption properties of polyvinyl chloride monitoring tubing are not significantly changed by the addition of a thin internal layer of polyethylene. It is therefore not worthwhile incorporating this feature into production.
