Randomized Controlled Trial Clinical TrialTramadol drops in children: analgesic efficacy, lack of respiratory effects, and normal recovery times.
Tramadol hydrochloride is a racemic mixture of two enantiomers. It has analgesic activity suitable for mild to moderate pain, part of its analgesic activity being modulated via mu receptors. Adult studies have raised the question of increased electroencephalographic activity. ⋯ Recovery times were 48.6 minutes (SD 32.3) (T) and 43.1 minutes (SD 32.5) (P) (P > .05). It is concluded that tramadol at 3 mg/kg has no clinical respiratory depressant effect and that behavior and recovery times are unaffected. Analgesic efficacy is demonstrated.

Randomized Controlled Trial Comparative Study Clinical TrialThe effect of a new type of video glasses on the perceived intensity of pain and unpleasantness evoked by a cold pressor test.
The aim of the study was to evaluate whether distraction induced by a new generation of video glasses (I-Glasses, Virtual i-O, Seattle, WA) has an effect on the perceived intensity of pain and unpleasantness. The effects of three-dimensional video, two-dimensional video, and no video glasses (control) were compared in two groups of healthy volunteers (13 males and 11 females) in a randomized, controlled trial. A cold pressor stimulus (1-2 degrees C chilled water) was used to induce experimental pain, and the volunteers rated the intensity of pain and unpleasantness on 100-mm visual analogue scales. ⋯ Three-dimensional video provided a significant reduction in both pain and unpleasantness (P < .01) compared with the control condition in the male group. However, in the female group, there was a significant reduction in unpleasantness with two-dimensional video compared with the control (P < .05). This suggests that the use of distraction by means of video glasses is able to reduce the perceived intensity of pain and unpleasantness.

ReviewKetamine: review of its pharmacology and its use in pediatric anesthesia.
The management of the uncooperative pediatric patient undergoing minor surgical procedures has always been a great challenge. Several sedative techniques are available that will effectively alleviate anxiety, but short of general anesthesia, no sedative regimen is available that will enable treatment of the uncooperative child. Ketamine produces a unique anesthetic state, dissociative anesthesia, which safely and effectively enables treatment of these children. The pharmacology, proposed mechanisms of action, and clinical use of ketamine (alone and in combination with other agents) are reviewed and evaluated.
