[Association of fentanyl or sufentanil an 0.5% isobaric bupivacaine in spinal anesthesia: a comparative study.].
Since the discovery of opioid receptors and the increase in spinal cord neuropharma- cological knowledge as to transmission and inhibition of nociceptive stimulations, there has been an increased interest in spinal drugs for anesthesiology and pain relief. This study aimed at prospectively evaluating the clinical efficacy of fentanyl (25 microg) and sufentanil (5 microg) with isobaric bupivacaine (10 mg), in patients submitted to spinal anesthesia for varicose vein surgery. ⋯ The addition of fentanyl (25 microg) and sufentanil (5 microg) to isobaric bupivacaine (10 mg) in spinal anesthesia affects sensory block levels.

Reappraisal of use of X-rays in childhood ankle and midfoot injuries.
To determine whether the Ottawa ankle rules (OAR) can be applied in children and what the potential reduction in the use of X-ray studies might be. ⋯ The Ottawa ankle rules are very sensitive and can be applied in children, resulting in a reduction in the use of X-rays studies.

Long-term experience with implanted intrathecal drug administration systems for failed back syndrome and chronic mechanical low back pain.
Continuous intrathecal drug delivery has been shown in open studies to improve pain and quality of life in those with intractable back pain who have had spinal surgery. There is limited data on long term effects and and even less for patients with mechanical back pain without prior spinal surgery. ⋯ We conclude that spinal drug administration systems appear to be of benefit in alleviating pain in the failed back syndrome and chronic mechanical low back pain but need to be examined prospectively.

This review aims to summarize results of recently published studies concerning clonidine application in paediatric anaesthesia, to analyse trends in these studies, and to discuss perspectives of the perioperative use of clonidine for children. ⋯ Clonidine may be less favored than midazolam as premedication for children because of inferior clonidine-induced sedation. Additional comparative studies are required, however, to confirm this finding. On the other hand, clonidine-induced analgesia may well be useful and find wide application in paediatric anaesthesia. Prospective multicentre trials using a larger number of patients will be needed to verify the usefulness of caudal clonidine for postoperative pain relief. Prophylactic use of clonidine against sevoflurane-induced agitation may represent a new and promising application. Assessment of the efficacy of clonidine in potentiating regional anaesthesia/analgesia by local anaesthetics in children also needs more investigation. Moreover, it may be worthwhile to try new successful applications demonstrated in adults for paediatric anaesthesia.

To examine the use of intravenous immunoglobulin (i.v.i.g.) in chronic pain. ⋯ Overall, 20% of patients had>70% pain relief and 27.7% of patients reported relief between 25% and 70%. Six patients (4.6%) had moderately increased pain levels for a duration of up to 9 weeks. Good relief, of more than 70%, was found in all major symptom groups. Patients with pain of short duration (<2 years) reported high relief rates (33.8% of patients in this group reported relief of >70%). No serious adverse events were reported. conclusions: i.v.i.g. may be effective in patients suffering from chronic pain. Controlled studies are needed to evaluate the efficacy of i.v.i.g. in these patients. Patients with a good response to i.v.i.g. may be models for the study of neuroimmune interactions in chronic pain.
