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 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.

Randomized Controlled Trial Comparative Study Clinical TrialAnesthetic efficacy of the intraosseous injection of 0.9 mL of 2% lidocaine (1:100,000 epinephrine) to augment an inferior alveolar nerve block.
The purpose of this study was to determine the anesthetic efficacy of an intraosseous injection of 0.9 mL of 2% lidocaine with 1:100,000 epinephrine to augment an inferior alveolar nerve block in mandibular posterior teeth. ⋯ The results of this study indicate that the supplemental intraosseous injection of 0.9 mL of 2% lidocaine with 1:100,000 epinephrine, given distal to the second premolar, significantly increased the success of pulpal anesthesia in the second premolar (for 50 minutes) and first molar (for 20 minutes) in comparison with the inferior alveolar nerve block alone. The intraosseous injection did not statistically increase success in the second molar.

Clinical Trial[Continuous parascalene block for shoulder surgery].
To evaluate the efficacy and incidence of side effects of parascalene brachial plexus block for shoulder surgery and for postoperative analgesia. ⋯ The parascalene approach is easy to use and entails few risks while providing excellent anesthetic conditions for open and arthroscopic shoulder operations. It is useful for ambulatory analgesia to facilitate early rehabilitation after surgery.

Bilateral continuous 3-in-1 nerve blockade for postoperative pain relief after bilateral femoral shaft surgery.
We tested the effectiveness of bilateral continuous paravascular femoral nerve blocks in a patient following bilateral femoral shaft surgery in whom other analgesic regimens were considered contraindicated or of limited effectiveness. Bilateral continuous femoral paravascular nerve blocks were performed using a previously described technique. General anesthesia was subsequently used to facilitate surgery, which was a bilateral osteosynthesis using dynamic hip screws for osteolytic metastases of the proximal extremities of both femurs. ⋯ Plasma concentrations of lidocaine were consistently below toxic levels (1.35 to 1.65 micrograms/ml). Radiographic contrast studies failed to demonstrate movement of contrast to the level of the lumbar plexus. Bilateral continuous femoral paravascular nerve blocks can be used to provide effective and safe analgesia in patients requiring aggressive analgesia in whom other techniques may be contraindicated.
