The accuracy of the output halothane concentration of seven draw-over halothane vaporizers (TEC, Ohmeda) which were delivered in 1986 to Malawi was investigated. They had not been serviced for the past 8 years. The output was studied at dial settings of 0.5%, 1%, 2%, 3%, 4%, and 5% at minute volumes of 2 to 8 litres before and after thorough cleaning of the vaporizers. ⋯ Whether the replacement of damaged wicks and seals would improve the accuracy further could not be investigated because these spare parts were not available. It is concluded from this study that regular servicing of draw-over vaporizers is essential. Support for the training of technicians in developing countries and also support for the funding of spare parts and measuring instruments in these countries should be considered by donors.

The mean age of patients was 26.9 years. There were 17 (46%) males and 20 (54%) females, with male:female ratio being 1:1.2. ⋯ The mean dose of atropine used in the first 24 h and during the hospital stay was 30.6 mg and 136.7 mg, respectively. The mean duration of treatment was 5.5 days (range 2-20 days). Two patients developed intermediate syndrome and the overall mortality among hospitalized patients was 8%.
