Randomized Controlled Trial Clinical Trial
Intrathecal labor analgesia using levobupivacaine 2.5 mg with fentanyl 25 microg--would half the dose suffice?
This randomized, double-blinded, controlled trial of 40 patients in early labor was conducted to determine whether a reduction in the total amount of intrathecal levobupivacaine and fentanyl would reduce the incidence of motor blockade and pruritus, respectively. ⋯ A reduction in the intrathecal dose of 2.5 mg levobupivacaine with 25 microg fentanyl by half is an option for CSE in labor because it can reduce the incidence of motor impairment. Although the reduced dose does not differ significantly from the full dose with respect to onset, duration, and quality of analgesia for the majority of parturients, it must be highlighted that insufficient labor analgesia may occur in certain individuals. In this respect, further studies related to dosage of intrathecal levobupivacaine in obstetric labor analgesia will be beneficial in substantiating this point.

Randomized Controlled Trial Comparative Study Clinical Trial
The sciatic nerve block in emergency settings: a comparison between a new anterior and the classic lateral approaches.
Anterior and lateral approaches to the sciatic nerve block are performed with the patient in the supine position. This could be an important advantage when mobilization to the limb involved is limited or painful, particularly in emergency conditions. The aim of this prospective, randomized study was to compare these two sciatic nerve blockades performed in an emergency setting. ⋯ These data suggest that both techniques are of similar value in an emergency setting.
