[Therapeutic application of anesthetic blocks in weever-fish stings].

Five cases of weaver-fish sting (weaver Trachinus) are described. All patients presented severe pain and peripheral vascular disorders. In 4 cases the sting was in the upper limb and treated with brachial plexus axillary block. One patient had been stung in the foot and treated with epidural continuous block with catheter: In all cases bupivacaine 0.5% was employed and evolution was good 24-48 hours later. We conclude that anesthetic blocks should be included in the symptomatic treatment of those cases, that is: steroids, antihistaminics, calcium, analgesic agents, antibiotics, and antitetanic vaccine.
