Some observations on the use of phenazocine (narphen) in Anaesthesia

  • Margaret Macpherson


  1. 1.

    Narphen is a potent analgesic for use during anaesthesia, and absence of restlessness in the post-operative period would suggest a prolongation of effect.

  2. 2.

    A pethidine-like respiratory depression occurs, which can be reversed by lethidrone, without any noticeable reduction in analgesia.

  3. 3.

    The patient can be maintained in adequate acid-base balance for long periods of anaesthesia with spontaneous respiration.

  4. 4.

    The drug is remarkably free from unpleasant side effects. It causes no cardiovascular depression, and minimal post-operative sequelae.

  5. 5.

    The recovery time is rapid.
