Randomized Controlled TrialIntermittent injection of bupivacaine into the margin or the cavity after reduction mammaplasty.
Twenty-seven operated women had postoperative intermittent injections of bupivacaine or saline for 24 hours after reduction mammaplasty. The injections were given five-hourly either subcutaneously along the submammary incision or deep into the wound. The patients were randomised into three groups of nine each: 5 ml bupivacaine 0.25% into the margin; 5 ml bupivacaine 0.25% into the cavity; and 5 ml physiological saline into the cavity. ⋯ Total morphine consumption was significantly (p<0.03) lower in patients given bupivacaine into the margin (2.0 (0.9) mg) or into the cavity (2.4 (0.8) mg) compared with controls (6.9 (1.5) mg). VAS pain scores and vomiting did not differ among the three groups. Postoperative intermittent infusion of bupivacaine lowered morphine consumption after reduction mammaplasty, and the analgesic effect seemed to be independent of where the infusion was given.

Cold injury by liquid petroleum gas is produced by evaporation that causes damage by cold to vital structures. We present two cases of exposure to pressurised liquid petroleum gas during an industrial accident.

Plexiform schwannoma is a rare benign neurogenic tumour; we report a case that arose in the ulnar nerve of a 59-year-old woman. Exploration showed a continuous multinodular tumour that involved the ulnar nerve from the hand to the upper arm; the length of the tumour was 35 cm.
