An association between intercostal nerve block and the development of a total spinal is rare. Usually, subarachnoid injection is considered to have followed intraneural placement or inadvertent entrance into a dural cuff extending beyond an intervertebral foramen. ⋯ This was a life-threatening event that occurred on two occasions before the definitive diagnosis was made. It is considered likely that the paravertebral catheter entered an intervertebral foramen and the tip perforated the dura.

This study assessed the efficacy of a modified transthecal digital block. Three-hundred-and-sixty consecutive digits were anaesthetised with this technique for the treatment of fractures, infections and foreign bodies. Complete palmar and dorsal anaesthesia was achieved in 357 of the 360 digits (99%), including 52 of 53 thumbs (98%). The technique was extremely easy to perform and no complications occurred.

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 TrialSelective ulnar nerve localization is not essential for axillary brachial plexus block using a multiple nerve stimulation technique.
The multiple-injection technique for axillary block, in which the 4 distal nerves of the plexus are located by a nerve stimulator and separately injected, has been shown to produce a rapid onset and a high success rate. However, this technique may be more difficult and time consuming than other axillary block methods. A simplified multiple-nerve stimulation technique, in which the ulnar nerve was not located, was compared in the present double-blind study to the 4-injection approach. ⋯ A triple-injection method of axillary block in which the ulnar nerve was not purposely located provides a spread and a latency of sensory block equal to that obtained with a 4-injection technique. A shorter performance time is an advantage of this approach.
