Randomized Controlled Trial Clinical Trial
Latency of brachial plexus block. The effect on onset time of warming local anaesthetic solutions.
A double-blind study was set up to investigate the effect of warming local anaesthetic solutions on the latency of onset of subclavian perivascular brachial plexus blocks. Twenty-four adult patients were randomly allocated into two equal groups. ⋯ The speed of onset of sensory blockade was significantly increased when the temperature of the local anaesthetic solution was increased to 37 degrees C. There were no adverse side effects in either group.

[Anatomy of extraoral block anesthesia of the maxillary nerve (precoronoid approach)].
The authors measured with sliding-calliper of 0.01 mm of accuracy bi-zigio distance and the distance between the foramen rotundum and vertex of the angle formed by the anterior border of the coronoid process with the lower border of the zygomatic bone. The sample was 160 brazilian adults skulls (50% male and 50% female). Using the Pearson's correlation they found the following results: 1) The positive correlation was reasonably strong in male at the right side between the maximal width of the face and the ideal depth, to reach with an injection needle, the maxillary nerve in the pterigopalatine fossa. 2) The correlation was moderately positive in male sex at the left side and in female at both sides. The formula of the line of regression found was: [table: see text]
