[Peripheral nerve stimulator for femoral nerve block. Is it really necessary?].
There are several methods to locate the femoral nerve in the perivascular inguinal space, being the most common the use of a peripheral nerve stimulator. This study aimed at evaluating femoral nerve block performed with peripheral nerve stimulator as compared to the loss of resistance to air technique, both by single injection or with catheter insertion. ⋯ Whereas the peripheral nerve stimulator is more widely used in the inguinal region, our study has shown that the loss of resistance to air technique is an effective and feasible alternative.
