Improving the efficiency of the drawover anaesthetic breathing system.

Abstract:

: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 percentage of oxygen at the common gas outlet when compared to a 300-ml reservoir tube. There was no difference in the percentage of oxygen when comparing a reservoir bag and a 600-ml reservoir tube.

  • Speed of injection and spread of bupivacaine in the epidural space.

    abstract::Speed of injection of bupivacaine was assessed in 73 women who received epidural analgesia in labour. Rapid injection was shown to produce quicker onset of epidural block and more reliable perineal anaesthesia than slow injection, but there was no difference in the final extent of the block. ...
