A syringe for extradural analgesia.
A specially designed 20 ml syringe for eliciting the loss of resistance test is described together with a suitably adapted Tuohy needle. This syringe and needle are primarily intended for use by those gaining experience in extradural analgesia (and such experience is readily transferred to any syringe) but it is considered that the consummate ease of operation will be appreciated by others.
