Randomized Controlled Trial Comparative Study Clinical Trial[Ultrasound-guided single dose injection of 0.5% levobupivacaine or 0.5% ropivacaine for a popliteal fossa nerve block in unilateral hallux valgus surgery].
To compare the perioperative analgesic efficacy of 0.5% levobupivacaine and 0.5% ropivacaine injected in a single dose to block the tibial and peroneal nerves for surgery using a posterior (popliteal fossa) approach. ⋯ The use of a single dose of either levobupivacaine or ropivacaine to provide anesthesia for a popliteal approach to hallux valgus surgery is effective for controlling postoperative pain.

Randomized Controlled Trial Comparative Study[Maternal hypotension with low doses of spinal bupivacaine or levobupivacaine and epidural volume expansion with saline for cesarean section].
Epidural volume extension (EVE) with saline solution can contribute to greater cephalad spread of drugs injected into the subarachnoid space during cesarean section. We studied the incidence of material hypotension with spinal bupivacaine or levobupivacaine (L-bupivacaine) and the spread after epidural saline injection. ⋯ The incidence of hypotension was lowest in the group anesthetized with 5 mg of L-bupivacaine, but the need for rescue analgesia was greater in this group. Doses of 5 mg and 6 mg may be sufficient for cesarean section, as they provide a good level of sensory blockade.
