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 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.

Randomized Controlled Trial Comparative Study Clinical Trial
Intercostal blockade and pulmonary function after cholecystectomy.
Sixty-six patients undergoing cholecystectomy were randomly allocated to receive either intercostal blockade with bupivacaine supplemented with papaveretum or papaveretum alone for postoperative analgesia. Both groups were similar regarding distribution of sex, age, and weight. These two groups were compared. ⋯ There was no significant difference, however, in the total consumption of papaveretum. Both groups experienced similar degrees of pain, and there were no differences in postoperative pulmonary function. We conclude that although single intercostal blockade is an effective analgesic, it does not improve pain relief and does not improve pulmonary function after cholecystectomy when compared with a regimen of on-demand, intramuscularly administered papaveretum.

Comparative StudyAcceptability of visual analogue scales in the clinical setting: a comparison with verbal rating scales in postoperative pain.
Pain is the clinical symptom most difficult to evaluate. Although clinical trials methodology have permitted assessment of pain objectively through rating scales, these strategies have not been used in clinical setting. The present study was undertaken to determine if visual analogue scales could be useful in the measurement of postoperative pain in usual medical practice. ⋯ The VAS of patients and researchers were also found to be highly correlated (p less than 0.001). When values of each group were compared by pain intensity a total agreement of VAS scores at low pain level could be established, but differences were found at high pain intensity levels, suggesting that physicians scored lower than patients when pain was severe to unbearable. It is concluded that VAS could be a reliable method to assess pain in clinical setting.
