Case Reports Clinical Trial
Bilateral paravertebral block: a satisfactory alternative for labour analgesia.
To describe a new technique of paravertebral block for labour analgesia and to report the successful use of bilateral paravertebral block in four parturients with contraindications to conventional labour epidural analgesia. ⋯ Bilateral paravertebral block provides adequate analgesia for the first stage of labour and could be an alternative analgesic technique for some parturients with contraindications to conventional labour epidurals.

Randomized Controlled Trial Clinical TrialAnesthetic efficacy of a combination of hyaluronidase and lidocaine with epinephrine in inferior alveolar nerve blocks.
The purpose of this prospective, randomized, double-blind study was to determine the anesthetic efficacy of a buffered lidocaine with epinephrine solution compared to a combination buffered lidocaine with epinephrine plus hyaluronidase solution in inferior alveolar nerve blocks. Thirty subjects randomly received an inferior alveolar nerve block using 1 of the 2 solutions at 2 separate appointments using a repeated-measures design. Mandibular anterior and posterior teeth were blindly pulp tested at 4-minute cycles for 60 minutes postinjection. ⋯ There were no significant differences (P > .05) between the 2 solutions. However, the combination lidocaine/hyaluronidase solution resulted in a significant increase in postoperative pain and trismus. It was concluded that adding hyaluronidase to a buffered lidocaine solution with epinephrine did not statistically increase the incidence of pulpal anesthesia in inferior alveolar nerve blocks and, because of its potential tissue damaging effect, it should not be added to local anesthetic solutions for inferior alveolar nerve blocks.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of two neurostimulation techniques for axillary brachial plexus blockade.
This prospective, randomized, double-blind study compared two techniques of axillary brachial plexus block using a peripheral nerve stimulator. Both groups received initial musculocutaneous nerve block followed by either a single injection on median nerve stimulation (group 1) or a double injection divided between median and radial nerves (group 2). ⋯ Complete sensory blockade of all six peripheral nerves occurred in 53% and 97% of patients in groups 1 and 2, respectively (P<0.001), with a more rapid onset of blockade occurring in group 2 patients (P<0.001). Complete motor blockade was evident in 30% and 83% of patients in groups 1 and 2, respectively (P<0.001).

Randomized Controlled Trial Clinical Trial
Interscalene brachial plexus anaesthesia with small volumes of ropivacaine 0.75%: effects of the injection technique on the onset time of nerve blockade.
We evaluated the effect of the injection technique on the onset time and efficacy of interscalene brachial plexus anaesthesia. ⋯ We conclude that using a multiple injection technique shortened the preparation time and improved the quality of interscalene brachial plexus anaesthesia performed with small volumes of ropivacaine 0.75%.
