Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The principal objective is to notice the relevance of timing performance of femoral block for knee replacement surgery during general anesthesia and analyze the relationship with bilateral bispectral index (BIS) monitoring during induction and maintenance of anesthesia. Otherwise the investigators try to investigate if the timing of performance of this block influence in postoperative variables as pain or blood loss.
