The value of anticonvulsant drugs in the treatment of some cases of lancinating pain is now established. The results in 170 consecutive cases in an ongoing series are reported with special reference to the efficacy of four anticonvulsants--carbamazepine, clonazepam, phenytoin and valproate. The findings are discussed.

The effectiveness of methadone given postoperatively by the lumbar epidural route to patients following upper abdominal or thoracic surgery was assessed. Intermittent injections of methadone diluted in large volumes of normal saline were given during the first 48 hours after surgery. Pain relief was assessed by both the patient and an observer using a visual linear analogue scoring system. Methadone 4-5 mg in 18-20 ml normal provided good postoperative pain relief for 6-8 hours.

Clinical Trial Controlled Clinical Trial
Analgesic efficacy of zomepirac sodium in patients with pain due to cancer.
In a single-dose, a double-blind crossover study in 40 patients with chronic pain due to advanced cancer, zomepirac sodium (Zomax), a new, single-entity, non-narcotic analgesic, was compared to oxycodone with APC (Percodan) and placebo. Both a verbal and a curvilinear visual analog scale were used in the study, and the results obtained were comparable. ⋯ Zomepirac sodium, 100 mg, appears to be an acceptable alternative to narcotic combinations such as oxycodone with APC in the management of moderate to severe cancer pain. The visual analog scale presented appears to be useful in the evaluation of analgesic efficacy and appears to be acceptable as an alternative to the more conventional verbal scale.

Randomized Controlled Trial Comparative Study Clinical TrialImproved pain relief after thoracotomy: use of cryoprobe and morphine infusion.
In a randomised controlled trial carried out during the first to days after thoracotomy patients who had had intercostal nerves frozen with a cryoprobe or were given morphine by continuous intravenous infusion had significant less pain at rest than patients given intramuscular morphine. Differences between the groups with respect to pain on movement and during physiotherapy were not significant. ⋯ The trial did not distinguish between the cryoprobe and infusion treatment. The simplicity of the cryoprobe had much to commend it, but in units without access to this equipment a small infusion pump offers a satisfactory alternative.
