Twenty pancreatic cancer patients were studied to assess the effectiveness and duration of celiac plexus block compared to traditional treatment with analgesics by considering the previous and subsequent consumption of narcotics until their death. After 1 week of therapy with NSAID-narcotic sequence according to the WHO method, 10 patients were continued on this treatment, while the other 10 patients underwent celiac plexus block. ⋯ Celiac plexus block made pain control possible with a reduction in opioid consumption for a mean survival period of about 51 days. Administration of only analgesics resulted in an equal reduction in VAS pain score until death, but with more unpleasant side effects than when using celiac plexus block.

Randomized Controlled Trial Comparative Study Clinical Trial
Continuous intercostal nerve block versus epidural morphine for postthoracotomy analgesia.
Twenty patients undergoing elective thoracotomy were randomized into two groups, receiving either lumbar epidural morphine (n = 10) or continuous extrapleural intercostal nerve block (n = 10). Subjective pain relief was assessed on a linear visual analogue scale. Pulmonary function (peak expiratory flow rate, forced expiratory volume in 1 second, and forced vital capacity) was measured on the day before operation and daily for 4 days after operation. ⋯ Vomiting, pruritus, and urinary retention occurred only in the epidural group, whereas nausea occurred significantly less frequently in the extrapleural group. We conclude that after thoracotomy continuous extrapleural intercostal nerve block is as effective as lumbar epidural morphine in reducing postoperative pain and restoring pulmonary mechanics. Because of the significantly lower complication rates we favor continuous extrapleural intercostal nerve block for postthoracotomy analgesia.

Randomized Controlled Trial Clinical Trial
Continuous intercostal analgesia with 0.5% bupivacaine after thoracotomy: a randomized study.
This study was undertaken to evaluate the effectiveness of 0.5% bupivacaine (360 mg/day) as a continuous infusion through an indwelling intercostal catheter inserted intraoperatively in the management of pain after thoracotomy. Eighty-six patients were randomized into three groups: group 1 = intercostal bupivacaine, group 2 = intercostal saline solution, and group 3 = fixed-schedule intramuscular buprenorphine. Supplementary buprenorphine was given as required. ⋯ No between-group differences in pulmonary function were observed. Respiratory complications occurred in no patients in groups 1 and 3 versus 5 in group 2 (p < 0.05). Continuous intercostal bupivacaine provided similar early pain control as compared with fixed-schedule narcotics but induced better analgesia with fewer complications than on-demand narcotics alone (group 2).
