Randomized Controlled Trial Comparative Study Clinical Trial
Imagery reduces children's post-operative pain.
This un-blinded experimental study investigated the effectiveness of imagery, in addition to routine analgesics, in reducing tonsillectomy and/or adenoidectomy pain and anxiety after ambulatory surgery (AS) and at home. Seventy-three children, aged 7-12, were recruited from five AS settings. Thirty-six children randomly assigned to the treatment group watched a professionally developed videotape on the use of imagery and then listened to a 30-min audio tape of imagery approximately 1 week prior to surgery (T1). ⋯ When controlling for trait anxiety, a two-way RM MANCOVA indicated no significant group differences in combined opioid and non-opioid use between the groups, or between times. Appropriately trained health care providers should use imagery to reduce post-operative pain following tonsillectomy and/or adenoidectomy in AS. Teaching parents about adequate home administration of analgesics may increase the effectiveness of imagery at home.

Randomized Controlled Trial Comparative Study Clinical Trial
The analgesic effects that underlie patient satisfaction with treatment.
Patient satisfaction and global ratings of study medications are increasingly used as secondary outcome measures in pain clinical trials. However, little is known about the factors that underlie and contribute to these ratings. 191 patients who participated in a randomized trial of parenteral parecoxib sodium followed by oral valdecoxib for pain following laparoscopic cholecystectomy versus standard care rated their satisfaction with the overall performance of the study medications (postoperative days 1 and 7) and also provided global evaluation of the analgesics on postoperative day 7. ⋯ These results were replicated in the prediction of day 7 ratings, except that at day 7, treatment regimen also made a significant independent contribution to the prediction of satisfaction. These findings indicate that the study participants considered more than one factor when estimating their satisfaction with the study medications, and that the changes produced by the treatment (e.g. decreased pain, opioid-related symptoms) mediated, in part, the effects of treatment on treatment satisfaction.

Randomized Controlled Trial Comparative Study Clinical Trial
Gabapentin for the prevention of postoperative pain after vaginal hysterectomy.
Gabapentin alleviates and/or prevents acute nociceptive and inflammatory pain both in animals and volunteers, especially when given before trauma. Gabapentin might also reduce postoperative pain. To test the hypothesis that gabapentin reduces the postoperative need for additional pain treatment (postoperative opioid sparing effect of gabapentin in humans), we gave 1200 mg of gabapentin or 15 mg of oxazepam (active placebo) 2.5 h prior to induction of anaesthesia to patients undergoing elective vaginal hysterectomy in an active placebo-controlled, double blind, randomised study. ⋯ Additionally, pretreatment with gabapentin reduced the degree of postoperative nausea and incidence of vomiting/retching possibly either due to the diminished need for postoperative pain treatment with opioids or because of an anti-emetic effect of gabapentin itself. No preoperative differences between the two groups were encountered with respect to the side effects of the premedication. However, 15 mg oxazepam was more effective in relieving preoperative anxiety than 1200 mg gabapentin.

Comparative Study Clinical Trial Controlled Clinical Trial
The effects of early or late neurolytic sympathetic plexus block on the management of abdominal or pelvic cancer pain.
Neurolytic sympathetic plexus block (NSPB) has been proposed to prevent the development of pain and improve the quality of life of patients with cancer, thus questioning the WHO protocol that proposes the use of invasive methods only as a final resort. This study evaluates the pain relief, opioid consumption and quality of life provided by the use of NSPB in two different phases of cancer pain and compares them with that provided by pharmacological therapy only. Sixty patients with abdominal or pelvic cancer pain were divided into three groups and observed for 8 weeks. ⋯ Opioid-related adverse effects were significantly greater in group III (P < 0.05). The occasional neurolysis-related complications were transitory. The results suggest NSPB for the management of cancer pain should be considered earlier in the disease.

Although pain is experienced at all ages, there is uncertainty about the pattern of its occurrence in older people. We have investigated the prevalence of three aspects of self-reported pain-occurrence of any recent pain, number and location of pain sites, and interference with daily life-to determine their association with age in older people. A cross-sectional postal survey of all adults aged 50 years and over registered with three general practices (n = 11230) in North Staffordshire using self-complete questionnaires was conducted. ⋯ Within each regional pain subgroup, the proportion of people who also reported pain interference rose with age. Our study has provided evidence that increasing age in the elderly population is not associated with any change in the overall prevalence of pain, although, as previous studies have suggested, the pattern of pain prevalence in different body regions does change with age. More importantly the extent to which pain interferes with everyday life increases incrementally with age up to the oldest age-group in the community-dwelling general population.
