We report a serious dysfunction of 19 halothane vaporisers Vapor 19.3 (Dräger) which delivered a much higher concentration of agent than indicated on the dial. This inaccuracy was linked to a major corrosion of the inner layers of the vaporiser, with a deposit of zinc bromide and chloride in the bypass channel. The main cause for this dysfunction was the absence of an adequate maintenance of the vaporisers since their purchase 3 years before.
我们报告了19台氟烷蒸发器Vapor 19.3（德尔格公司）出现的严重故障，这些蒸发器所输送的麻醉剂浓度比刻度盘上显示的要高得多。这种不准确与蒸发器内层的严重腐蚀有关，旁路通道中有溴化锌和氯化锌沉积。造成这种故障的主要原因是自3年前购买以来，这些蒸发器没有得到充分的维护。
