Clinical Trial[Sciatic nerve block. Description of a new posterior approach in the gluteal area].
To describe and assess the clinical usefulness of a new posterior approach for sciatic nerve block to the gluteal zone. ⋯ We describe a new approach for sciatic nerve block using only two points of osseous reference identified by palpation. The level of efficacy and safety is high.

Comment Randomized Controlled Trial Comparative Study Clinical Trial[Comparative study between 5% prilocaine and 2% mepivacaine by the subarachnoid route in transurethral resections].
To compare the duration of spinal block with 5% prilocaine and 2% mepivacaine in short procedures for transurethral resection and to assess possible complications in the immediate postoperative period. ⋯ Both local anesthetics offer good surgical conditions with hemodynamic stability and few complications. The duration of sensory and motor blockade is shorter with prilocaine than with mepivacaine, making prilocaine more appropriate for short interventions.

Review Historical Article[Subarachnoid anesthesia: 100 years of an established technique].
Over the 100 years since the introduction of spinal anesthesia into clinical practice, this technique, like most others, has enjoyed varying degrees of popularity. The attraction of spinal anesthesia is easy to identify: a relatively simple technique is used to inject a very small amount of drug into a readily identifiable body compartment to provide deep anesthesia. ⋯ In addition to reviewing the history of spinal anesthesia and the local anesthetics and adjuvant drugs administered by this route, we discuss single-dose and continuous spinal injection, combined spinal-epidural technique, and spinal anesthesia for outpatient settings. The problems typical of dural puncture and placement of local anesthetics and adjuvant drugs into the intrathecal space are also reviewed.

Review[Combined subarachnoid-epidural technique for obstetric analgesia].
Combined spinal-epidural blockade for labor pain has enjoyed increasing popularity in obstetric anesthesia. The usual procedure is to use a single space and a single needle for dural puncture, inserting a spinal needle through an epidural needle followed by insertion of a catheter. A small dose of one or several substances (usually a lipophilic opioid and a local anesthetic) is first injected in the intrathecal space to provide rapid, effective analgesia with minimal muscle blockade. ⋯ The most widely-recognized advantage of the technique is high maternal satisfaction with rapid and effective analgesia. Mobility of the lower extremities is preserved and the mother is often able to walk. Because opioids are injected into the intrathecal space and because the technique is more invasive than standard epidural analgesia, the potential risk to mother and fetus increases.
