        Instruction to wait for pulsations of the cord to cease before clamping

    A MIDWIFERY SURGICAL CLAMP

    In the old method of dividing the umbilical cord the accoucheur after tying the
    first thread pressed the blood in the vessels some distance along the cord
    which was then held by an assistant until the second thread was tied, the
    object being to avoid the escape of blood on to the bedclothes. This part of
    the accoucheur’s work may, however, be accomplished more conveniently by
    making use of a clamp which I have designed and which is represented open
    in Fig. 1 and closed in Fig. 2, for it by the same movement cuts the cord and
    compresses both the cut ends, thereby supplying the place of scissors and
    ligatures. The clamp having been opened, the cord when it has ceased to
    pulsate is placed between the blades, resting on the plain side; the knifed
    edge is then pressed firmly down and retained in position by the catch. The
    clamp is removed a few seconds after application, and if the accoucheur is
    afraid of haemorrhage (although French authorities say there is no need for
    ligatures) he can tie the cord on either side of the clamp before releasing the
    catch. The instrument is neat and easy to use. Messrs. Arnold and Sons,
    London, are the makers.                           EDWARD MAGENNIS, M.D. R U.I.
