Randomized Controlled Trial Comparative Study Clinical Trial
[Use of new elastomeric pumps and PCA in postoperative pain control in thoraco-abdominal surgery].
36 patients submitted to interventions for thoraco-abdominal surgery has been submitted to antalgic post-operatory therapy with elastomeric pump at a continuous intravenous infusion and patient controlled analgesia (PCA). The patients have been randomized in three groups. The patients of the 1 degree group received 30 minutes before of the end of the surgical intervention 30 mg of Ketorolac. ⋯ In the 2 degree group to the awakening (T0), the pain was middle-tall (5.50 +/- 2.32) and an expressive reduction appeared at the time T2 (3.60 +/- 1.35 P < 0.005). In the 3 degrees group have not recorded a diminution of the pain if not after 24 hours from the end of the intervention deposit the intramuscular antalgic therapy. In conclusion, the system infusion + PCA represents an indubitable advantage in comparison with the traditional antalgic therapy as for concern the entity of the reduction of the pain as because it permits the use of a smaller quality of drugs.

Role of magnesium sulfate in postoperative analgesia.
N-methyl-D-aspartate antagonists may play a role in the prevention of pain. An assessment was made of the effect of the physiologic N-methyl-D-aspartate antagonist magnesium on analgesic requirements, pain, comfort, and quality of sleep in the postoperative period. ⋯ This is the first clinical study showing that the perioperative application of magnesium sulfate is associated with smaller analgesic requirement, less discomfort, and a better quality of sleep in the postoperative period but not with adverse effects. Magnesium could be of interest as an adjuvant to postoperative analgesia.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA double-blind study of subcutaneous dihydroergotamine vs subcutaneous sumatriptan in the treatment of acute migraine.
To assess the efficacy and tolerability of subcutaneous dihydroergotamine mesylate (DHE-45) vs subcutaneous sumatriptan succinate (Imitrex) for the treatment of acute migraine with or without aura. ⋯ Both sumatriptan and dihydroergotamine were effective in aborting migraine headaches. Headache recurrence was two and a half time as likely with sumatriptan as with dihydroergotamine.

Randomized Controlled Trial Comparative Study Clinical Trial
Amitriptyline effectively relieves neuropathic pain following treatment of breast cancer.
The effectiveness of amitriptyline in relieving neuropathic pain following treatment of breast cancer was studied in 15 patients in a randomised, double-blind placebo-controlled crossover study. The dose was escalated from 25 mg to 100 mg per day in 4 weeks. The placebo and amitriptyline phases were separated by a 2-week wash-out period. ⋯ The 'poor responders' reported significantly more adverse effects with amitriptyline and placebo than the good responders. It is concluded that amitriptyline effectively reduced neuropathic pain following treatment of breast cancer. However, the adverse effects of amitriptyline put most of the patients off from using the drug regularly.

Randomized Controlled Trial Clinical TrialDose dependent time course of the analgesic effect of a sustained-release preparation of tramadol on experimental phasic and tonic pain.
1. The aim of this study was to investigate the analgesic effect and its duration of a new sustained-release preparation of tramadol in an experimental pain model based on pain-related chemosomatosensory evoked potentials (CSSEPs) and subjective intensity estimates of painful phasic and tonic stimuli. 2. Twenty volunteers participated in a randomised, double-blind, three-fold cross-over study. ⋯ The observed slight decrease in the estimates of phasic pain under medication did not reach a statistically significant level when compared with placebo. No significant effect could be demonstrated for the perception of the phasic and the tonic pain as determined by the McGill-Questionnaire. 5. A significant dose-related increase in the estimates of the side effects 'drowsiness', 'vertigo' and 'sickness' but not for 'tiredness' could be demonstrated.
