Drawover anaesthesia and preoxygenation.

We have studied the efficacy of preoxygenation using the Triservice Anaesthetic Apparatus (TSA) in healthy patients and found it to be unsatisfactory. An alternative technique suitable for field use was explored. The Mapleson D system (Bain) was found to be suitable for preoxygenation with a fresh gas flow of only 4 litre of oxygen per minute. In a randomized study using only 4 litre of oxygen ...

A modified method for the determination of halothane and other halogen-containing anaesthetics.

DUNCAN (1959) described a method for determining halothane in tissues, body fluids and gases, based on the liberation of chloride and bromide ions by the action of an ethereal solution of lithium aluminium hydride. The reagent is somewhat troublesome to prepare and can only be kept under conditions which rigidly exclude moisture. Some workers have experienced difficulties in obtaining anhydrous...

A Modified Orcinol Reaction for RNA Determination

Improving the efficiency of the drawover anaesthetic breathing system.

We investigated modifications to the reservoir tube usually used in drawover anaesthetic breathing systems as a method of improving its efficiency and performance. The resulting oxygen concentration was recorded at different oxygen flow rates whilst an artificial lung was being ventilated over a range of minute volumes. Addition of a reservoir bag and valves significantly increased the measured...
