Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of multiple against single pain intensity measurements in complex regional pain syndrome type I: analysis of 54 patients.
To describe the comparison of multiple and single pain ratings in patients with complex regional pain syndrome type I (CRPS I). ⋯ In patients with CRPS I a single pain rating is an accurate predictor of the average pain measured by a multiple pain-rating test. Moreover, both assessments are accurate enough to determine changes in pain over time with an effective treatment.

Cortical potentials related to assessment of pain intensity with visual analogue scale (VAS).
To elucidate brain mechanisms underlying the psychophysical processes to measure pain intensity, pain-related somatosensory evoked potentials (pain SEPs) following painful CO(2) laser stimulation were studied while employing a task to measure intensity of pain on a visual analogue scale (VAS). ⋯ IAP is an event-related potential (ERP) associated with assessment of pain intensity but not influenced by pain intensity itself. From its scalp distribution, it can be assumed that the assessment of pain intensity involves multiple areas in both hemispheres.

Watch needle, watch TV: Audiovisual distraction in preschool immunization.
To evaluate the effectiveness of audiovisual distraction compared with a blank TV screen in the reduction of pain associated with intramuscular immunization. ⋯ Watching cartoons did not distract children during needle injection nor reduce their pain. Looking at the TV screen was related to lower behavioral pain scores in the total sample.

Randomized Controlled Trial Comparative Study Clinical TrialParent visual analogue scale ratings of children's pain do not reliably reflect pain reported by child.
To determine whether parent and child visual analogue scale (VAS) scores for the pain associated with acute conditions in the child agree sufficiently for these methods of measurement to be considered interchangeable in pain and analgesia research. ⋯ Parents' VAS score ratings of their children's pain correlate only moderately with the children's VAS pain scores and show poor levels of agreement. The difference between the measures is variable and appears to be more marked when the child reports a higher VAS score. This research raises doubt about whether parental rating of a child's pain is an appropriate surrogate marker in pediatric pain and analgesia research.

Intravenous single-dose tramadol versus meperidine for pain relief in renal colic.
Comparison of the effectiveness of tramadol with meperidine given intravenously to emergency patients with suspected renal colic. ⋯ Meperidine 50 mg was superior to tramadol 50 mg for acute pain relief in patients with suspected renal colic when given intravenously. Because many patients in both groups received supplemental meperidine and the response to tramadol alone cannot be predicted, clinicians may want to choose higher doses of meperidine alone or other alternative combinations.
