Abstract |
Background |
Wrist blockage of median and ulnar nerves before treatment of palmar hyperhidrosis with botulinum toxin (BTX-A) reduces discomfort and improves accuracy of BTX-A injections, but can be associated with mechanical/chemical injury.
Objectives |
We sought to compare locoregional anesthesia of median and ulnar nerves using conventional 25-G × 0.50 × 13 mm gauge needle with short 30-G × 0.40 × 6 mm gauge needle.
Methods |
In all, 37 patients with idiopathic, recalcitrant palmar hyperhidrosis were treated with BTX-A after median and ulnar nerve blockage. In 18 patients, a conventional needle was used to achieve nerve blockage and in 19 the short needle was used. The 2 groups of patients were compared for analgesic effects and lag phase.
Results |
No differences were found between groups for lag phase (P=.26) and discomfort of subsequent BTX-A treatment (P=1.0).
Conclusion |
The use of a short-gauge needle to block median and ulnar nerves is a suitable method to anesthetize the palm before treatment with BTX-A.
