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.

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.

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.
