To demonstrate the effectiveness of Sarapin in prolonging the action of neural blockade with improved pain relief. ⋯ This prospective, double-blind trial of 500 patients undergoing 828 treatments, one time with Sarapin and a subsequent time without, with each patient acting as their own control, showed no significant differences in the pain relief or duration of significant relief with the addition of Sarapin.

Randomized Controlled Trial Clinical Trial
[Bupivacaine for continuous interscalene brachial plexus analgesia after shoulder surgery].
This study evaluates clinical efficacy of continuous interscalene brachial plexus block with bupivacaine 0.15% for postoperative analgesia after shoulder surgery. ⋯ Continuous interscalene brachial plexus analgesia is a reliable and effective method of providing postoperative pain relief after shoulder surgery and is superior to the systemic analgesia.

Randomized Controlled Trial Comparative Study Clinical TrialThe effects of three different approaches on the onset time of sciatic nerve blocks with 0.75% ropivacaine.
We studied three different injection techniques of sciatic nerve block in terms of block onset time and efficacy with 0.75% ropivacaine. A total of 75 patients undergoing foot surgery were randomly allocated to receive sciatic nerve blockade by means of the classic posterior approach (group classic; n = 25), a modified subgluteus posterior approach (group subgluteus; n = 25), or a lateral popliteal approach (group popliteal; n = 25). All blocks were performed with the use of a nerve stimulator (stimulation frequency, 2 Hz; intensity, 2-0.5 mA) and 30 mL of 0.75% ropivacaine. Onset of nerve block was defined as complete loss of pinprick sensation in the sciatic nerve distribution with concomitant inability to perform plantar or dorsal flexion of the foot. In the three groups, an appropriate sciatic stimulation was elicited at <0.5 mA. The failure rate was similar in the three groups (group popliteal: 4% versus group classic: 4% versus group subgluteus: 8%). The onset of nerve block was slower in group popliteal (25 +/- 5 min) compared with group classic (16 +/- 4 min) and group subgluteus (17 +/- 4 min; P < 0.001). There was no significant difference in the onset of nerve block between group classic and group subgluteus. No differences in the degree of pain measured at the first postoperative administration of pain medication were observed among the three groups. We conclude that the three approaches resulted in clinically acceptable anesthesia in the distribution of the sciatic nerve. The subgluteus and classic posterior approaches generated a significantly faster onset of anesthesia than the lateral popliteal approach. ⋯ Comparing three different approaches to the sciatic nerve with 0.75% ropivacaine, the classic and subgluteal approaches exhibited a faster onset time of sensory and motor blockade than the lateral popliteal approach.

Randomized Controlled Trial Comparative Study Clinical Trial
The posterior lumbar plexus (psoas compartment) block and the three-in-one femoral nerve block provide similar postoperative analgesia after total knee replacement.
To compare the efficacy of a continuous posterior lumbar plexus (PSOAS) block to a continuous three-in-one femoral nerve (FEM) block in patients undergoing primary total knee replacement (TKR). ⋯ Both continuous PSOAS block and continuous three-in-one FEM block provided better analgesia than PCA but no differences were seen between the two regional techniques.
