Randomized Controlled Trial Comparative Study Clinical Trial
Maintenance and recovery characteristics after sevoflurane or propofol during ambulatory surgery in children with epidural blockade.
To compare the maintenance and recovery characteristics after sevoflurane with those after propofol in children with epidural blockade. ⋯ Sevoflurane and propofol exhibit similar maintenance and recovery profiles when combined with epidural analgesia in children undergoing ambulatory surgery.

Randomized Controlled Trial Comparative Study Clinical TrialUltrasonographic guidance reduces the amount of local anesthetic for 3-in-1 blocks.
Recently it has been demonstrated that the use of ultrasound (US) improves the onset time and the quality of sensory block for 3-in-1 blocks compared with conventional nerve stimulator (NS) techniques. The present study was designed to evaluate if US guidance for 3-in-1 blocks reduces the amount of local anesthetic compared to NS guidance. ⋯ The amount of local anesthetic for 3-in-1 blocks can be reduced by using US guidance compared with the conventional NS-guided technique.

Randomized Controlled Trial Comparative Study Clinical Trial
Bupivacaine 0.125% produces motor block and weakness with fentanyl epidural analgesia in children.
Epidural infusions of fentanyl (2 micrograms.ml-1) alone or combined with bupivacaine 0.125% were compared for perioperative analgesia, motor block and other side-effects in children who underwent urological surgery. ⋯ Postoperative epidural fentanyl infusion provides equipotent analgesia to administration of a solution including both fentanyl and bupivacaine 0.125% and causes less lower limb weakness. No reduction in the fentanyl requirement resulted from the addition of bupivacaine 0.125%.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of phenol block and botulinus toxin type A in the treatment of spastic foot after stroke: a randomized, double-blind trial.
Locally acting treatments for spasticity such as nerve and motor point blocks have the advantage of reducing harmful spasticity in one area, while preserving useful spasticity in another area. This randomized, double-blind study is the first trial that was designed to find out whether botulinus toxin Type A and phenol relieves the signs and symptoms of ankle plantar flexor and foot invertor spasticity after stroke and if either of these methods offers any advantages and disadvantages over the other. Twenty patients who were included in this preliminary study were randomly assigned to receive a single treatment of 400 mouse units of botulinus toxin Type A injected into the calf muscles or to receive a tibial nerve blockade with 3 ml of 5% phenol. ⋯ The decrease in clonus duration that was detected by electromyography was significant in both groups at all visits, but the decrease in the group that received botulinus toxin Type A was significantly better at Weeks 2 and 4 (P < 0.05). It is concluded that both motor point injections with botulinus toxin Type A and tibial nerve blockade with phenol are effective in plantar flexor spasticity, but the changes were more significant in the group that received botulinus toxin Type A at Weeks 2 and 4, whereas there was not a significant difference between the two groups at Weeks 8 and 12. Future research should explore the long-term effect of these two treatment modalities.
