A modified technique of intercostal nerve blockade is described which is suitable for use in children. Ten patients received intercostal nerve blockade on a total of 29 occasions in order to provide analgesia following liver transplantation and to facilitate weaning from artificial ventilation of the lungs. ⋯ The technique has proved to be safe in skilled hands. It is an acceptable method of postoperative analgesia in children after liver transplantation and may be a useful technique in the management of other paediatric patients.

Randomized Controlled Trial Comparative Study Clinical Trial
A double-blind comparison of the relative efficacy, side effects and cost of buprenorphine and morphine in patients after cardiac surgery.
The analgesic efficacy, side effects and cost of administration of regimens of intravenous buprenorphine and intravenous morphine were compared in a randomized double-blind trial performed during the first 24 h after cardiac surgery. Seven patients received buprenorphine by intermittent intravenous injection and six received morphine by continuous infusion. Both these regimens provided good analgesia for the entire 24 h period, with only mild pain at rest and moderate pain on vigorous coughing. ⋯ Buprenorphine had no narcotic code restriction and could be given by intermittent intravenous injection, whereas morphine required checking and handling as a restricted drug and administration by continuous intravenous infusion. When labour and material costs were computed, over the first 24 postoperative hours, it cost $19.76 per patient to administer morphine, but only $3.16 to administer buprenorphine. Thus the use of buprenorphine injections for the first 24 h after cardiac surgery produced pain relief and respiratory depression comparable to that produced by a morphine infusion, but with a significant cost saving in terms of labour and materials.

Randomized Controlled Trial Clinical Trial
Role of cryoanalgesia in the control of pain after thoracotomy.
Thoracotomy causes severe postoperative pain, which is difficult to manage since the use of systemic analgesics often causes respiratory depression. Cryoanalgesia of the intercostal nerves has been advocated as an effective means of local analgesia without serious side effects. A prospective randomised blind trial to investigate the efficacy of the technique was carried out. ⋯ Statistical analysis of the scores of postoperative pain and analgesic consumption showed that there was no significant difference between the trial and the control group. There was, however, a suggestion of an increase in the long term morbidity, although these figures were not amenable to statistical analysis. Thus is has not been possible to demonstrate a role for cryoanalgesia in the control of post thoracotomy pain.

The safety and efficacy of a disposable, nonelectronic, patient-controlled-analgesia (PCA) device for alleviating postoperative pain were evaluated. Patients who were to undergo abdominal surgical procedures under general anesthesia were instructed in the use of the Travenol Infusor with Patient Control Module. Patients used the PCA device upon emerging from anesthesia in the recovery room. ⋯ Results of a poststudy self-assessment questionnaire showed that 90% of the patients reported experiencing mild to moderate pain overall, and 78% reported only mild discomfort throughout the postoperative period. Ninety-two percent of the patients strongly preferred PCA therapy over intramuscular injections. The Travenol Infusor with Patient Control Module represents a safe and effective device for PCA therapy of postoperative pain.
