简要总结
Stimulating catheters have been introduced to reduce the incidence of secondary failure after continuous peripheral nerve blocks, but they effectiveness over traditional nonstimulating catheters is still controversial. The aim of this prospective, randomized, blinded study is to detect if stimulating catheters improve postoperative compared with conventional non-stimulating catheters.
