Randomized Controlled Trial Clinical Trial
Double-blind evaluation of analgesic efficacy of orally administered diclofenac, nefopam, and acetylsalicylic acid (ASA) plus codeine in chronic cancer pain.
The analgesic efficacy and toxicity of oral diclofenac sodium 50 mg (q.i.d.) vs. nefopam 60 mg (q.i.d.) and a combination of 640 mg ASA and 40 mg codeine (q.i.d.) in cancer patients with moderate to severe chronic pain has been evaluated in a randomized double-blind study. Planned duration of treatment was 10 days. Pain intensity was evaluated by a visual analog scale. ⋯ Patients treated with nefopam had a significantly shorter period in the study than patients treated with the other 2 treatments. Adverse effects were slightly more frequent with the nefopam and ASA + codeine regimens. The 3 therapeutic regimens appear to be similar as to analgesic efficacy, but diclofenac presents the advantage of a slightly better safety profile than nefopam and the ASA + codeine combination.

Randomized Controlled Trial Comparative Study Clinical TrialEffects of epidural bupivacaine and epidural morphine on bowel function and pain after hysterectomy.
A comparison was made of the effects of continuous epidural analgesia with bupivacaine and intermittent epidural morphine on bowel function after abdominal hysterectomy. The duration of postoperative ileus was assessed as the time from the end of operation to the first postoperative passage of flatus and feces. Twenty-two patients were randomly allocated to two equal groups. ⋯ The time to first postoperative passage of feces was shorter (P less than 0.05) in the former than in the latter 57 +/- 44 h vs 92 +/- 22 h). The patients of the epidural bupivacaine group started intake of oral fluids earlier (P less than 0.01) and to a greater extent (P less than 0.05) than those in the epidural morphine group. It is concluded that the duration of postoperative ileus after hysterectomy is shorter when epidural bupivacaine is given for postoperative pain relief than when this is achieved by epidural morphine.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of continuous paravertebral and extradural infusions of bupivacaine for pain relief after thoracotomy.
Pain was controlled in 20 post-thoracotomy patients using a continuous infusion of 0.25% bupivacaine through an extradural or para-vertebral catheter. Both techniques provided good analgesia. Hypotension and urine retention occurred significantly less frequently in the paravertebral than in the extradural group.

Randomized Controlled Trial Clinical Trial
Effect of diluting propofol on the incidence of pain on injection and venous sequelae.
The effect of diluting propofol in 5% dextrose on the incidence of i.v. injection pain was studied in 100 adult patients. Severe injection pain occurred in 32% (16 patients) who received undiluted propofol, compared with 10% (five patients) who received dilute propofol. We concluded that the dilution of propofol significantly reduced the incidence of severe pain during injection without increasing postoperative venous sequelae.

Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical TrialTreatment of post-thoracotomy pain with intermittent instillations of intrapleural bupivacaine.
The effect of intrapleural bupivacaine in the treatment of post-thoracotomy pain was evaluated. Bupivacaine, 0.5% 20 ml, with adrenaline (5 micrograms/ml) was given through an indwelling intrapleural catheter, at 4-h intervals four times daily for 2 days. No pleural suction was applied during and 10 min after each injection. ⋯ The VAS and PQ scores 30 min after bupivacaine instillations diminished to an extent similar to that after oxycodone treatment. The need for analgesics during the day of operation was less in the bupivacaine group than in the control group (P less than 0.001). The number of oxycodone supplementation doses during 48 h postoperatively was, however, not smaller in the bupivacaine group than in the control group.
