Case Reports
Field experience with the Triservice anaesthetic apparatus in Oman and Northern Ireland.
Experience gained by two anaesthetists using the Triservice halothane, trichloroethylene air and oxygen draw-over apparatus in the field and in a sophisticated hospital is described and discussed.

The value of anticonvulsant drugs in the treatment of some cases of lancinating pain is now established. The results in 170 consecutive cases in an ongoing series are reported with special reference to the efficacy of four anticonvulsants--carbamazepine, clonazepam, phenytoin and valproate. The findings are discussed.

A series of 30 multiple choice questions were modified for presentation on a microcomputer which was programmed to present them to the user and mark them. In a preliminary study, 15 trainee anaesthetists all agreed the system was satisfactory as an aid to preparation for the FFARCS.

The Triservice anaesthetic apparatus is a draw-over using ambient air as the primary carrier gas. Its modules are a self-inflating bag, a vaporiser, a supplementary oxygen regulator and a ventilator; each is described. The outputs of halothane and trichloroethylene were measured with changes of temperature, continuous and intermittent gas flows and with alteration in barometric pressure. ⋯ The resistance to airflow of the apparatus was also measured and the effect of extreme cold observed. The merits, limitations and the way in which the equipment may be used are discussed. A carrying case with equipment for 10 anaesthetics is illustrated.
