Further research is needed to determine a clinically effective dose with shorter duration of motor block for magnesium used as an additive to spinal analgesic agents
As part of a multimodal analgesia approach the use of femoral and sciatic nerves blocks with bupivacaine appears to be an alternative technique to help with analgesia and anesthesia during surgery.
Bupivacaine administered via femoral nerve block can provide short-term postoperative analgesia not different to that with administration via lumbosacral epidural.
