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 Trial
Differential sensory block: spinal vs epidural with lidocaine.
In this study we sought to determine if and when a difference exists with regards to differential sensory blockade between spinal and epidural anaesthesia using lidocaine. ⋯ Spinal and epidural anaesthesia with lidocaine produce a similar degree of differential sensory blockade. Epidural anaesthesia produces a detectable difference between the level of analgesia and cold sensation at various times, whereas spinal anaesthesia did not reliably do so in this study.

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 Trial
Postdural puncture headache after spinal anaesthesia in young orthopaedic outpatients using 27-g needles.
Two large studies reported a very low rate (0.5-1.8%) of postdural puncture headache (PDPH) with the use of 27-G spinal needles. We suspected that it might be higher in young ambulatory patients. The purpose of this study was to establish the rate prospectively in such a patient population using two types of needles. ⋯ The rate of PDPH was higher than in large published studies with 27-G Quincke and Whitacre needles and greater in women than in men.

Randomized Controlled Trial Clinical Trial
Epidural saline solution prior to local anaesthetic produces differential nerve block.
The loss-of-resistance technique is generally used to identify the epidural space usually with normal saline. However, the effect of epidural saline on anaesthetic spread has not been demonstrated. The purpose of this study was to determine whether epidural saline affected the anaesthetic level and the quality of analgesia. ⋯ Our results suggest that a large volume of saline solution injected in the epidural space to elicit loss-of-resistance dilutes the local anaesthetic solution, resulting in reduced spread of the block to pinprick.
