To determine the most effective local anaesthetic for or in the pain caused by its injection or the procedure. ingrown toenail surgery, 100 procedures were performed Significant differences were found between treatments with after patients had been randomized to receive lignocaine, respect to pain at dhharge from hospital and signi5cantly bupivacaine or hyaluronidase and bupivacaine. The effect fewer patients who received bupivacaine experienced pain of each anaesthetic was monitored and 80 patients returned 24 h after surgery (P= 0002). Bupivacaine provides quicka follow-up questionnaire. There was no significant acting and long-lasting anaesthesia and should be used in difference in the time for the local anaesthetic to take effect, preference to lignocaine.
Ingrown toenail is a common condition treated by a variety of practitioners'.2. Segmental ablation of the germinal matrix by surgery or phenolization under local anaesthesia is recommended as the most effective treatment'^^^. Postoperative pain can be considerable and the procedure is usually performed under 'ring block' local anaesthesia'. Lignocaine is frequently used as the anaesthetic agent; bupivacaine is slower to act but longer lasting. The speed of action of bupivacaine may be increased by the addition of hyaluronidase. This study examined the efficacy of three ring block local anaesthesia regimens.
