Clinical Trial[Midfemoral nerve block for foot surgery: is there an anatomical-clinical correlation between motor response and latency?].
The latency times of midfemoral sciatic nerve blocks vary greatly. This study investigated the correlation between the type of motor response to nerve stimulation on the one hand and latency and block efficacy on the other. ⋯ This approach provides an effective block with minimum latency in patients who have a flexion or extension motor response in the foot and/or fingers, inversion, or plantar flexion, which assumes that the injection has reached the common trunk of the sciatic or tibial nerve. However, a longer latency is associated with a peroneal motor response, particularly eversion.

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.

[Manual single infusion of combined remifentanil and propofol for anesthesia during laparoscopic gynecology procedures: a case series].
To describe a single manual infusion technique for total intravenous anesthesia with remifentanil and propofol. ⋯ Total intravenous anesthesia by means of a single manual infusion of remifentanil and propofol provided appropriate anesthetic and surgical conditions, with rapid, predictable awakening.
