Randomized Controlled Trial Clinical TrialPatients' perception of pain during axillary and humeral blocks using multiple nerve stimulations.
Axillary or humeral blocks by multiple nerve stimulation (MNS) are used for ambulatory hand surgery. This double-blind study identified which of the three main components of the procedure (repeated needle passes, local anesthetic injections, or electrical stimulations) is most painful, quantified its intensity, and recorded patients' preferences for a future anesthetic. ⋯ This study found that more axillary-block patients compared with humeral-block patients reported electrical stimulation as the most unpleasant part of the block but failed to detect significant differences in the intensity of the 3 block components (repeated needle passes, local anesthetic injections, and electrical stimulations). Most patients in both groups would accept the same block for future hand operations. Patients were ready for surgery sooner after axillary block, but the clinical importance of this finding is doubtful.

Randomized Controlled Trial Clinical TrialRopivacaine 3.75 mg/ml, 5 mg/ml, or 7.5 mg/ml for cervical plexus block during carotid endarterectomy.
To examine the effect of 225 mg (7.5 mg/mL), 150 mg (5 mg/mL), and 112.5 mg (3.75 mg/mL) ropivacaine on quality of cervical plexus block during carotid endarterectomy. ⋯ The best quality of cervical plexus block associated with the smallest incidence of pain for patients undergoing carotid endarterectomy was obtained with 30 mL of 225 mg and 150 mg of ropivacaine, respectively.

Randomized Controlled Trial Comparative Study Clinical TrialProspective comparison of continuous femoral nerve block with nonstimulating catheter placement versus stimulating catheter-guided perineural placement in volunteers.
Stimulating catheter-guided perineural placement may potentially increase the success rate and quality of continuous femoral nerve block as compared with a nonstimulating catheter technique. These hypotheses have not been rigorously tested. ⋯ In this volunteer study, there was no statistically significant difference in block success between the two techniques. However, stimulating catheter-guided placement provided an increased overall quality of continuous femoral perineural blockade. Further studies are needed to verify these observations in the clinical setting.

Randomized Controlled Trial Comparative Study Clinical TrialSpinal ropivacaine or bupivacaine for cesarean delivery: a prospective, randomized, double-blind comparison.
The aim of this prospective, randomized, double-blinded study was to compare clinical efficacy and safety of ropivacaine and bupivacaine given intrathecally in combination with morphine for cesarean delivery. ⋯ Spinal anesthesia produced with 20 mg ropivacaine plus 0.1 mg morphine is as effective and safe as that provided by 15 mg bupivacaine plus 0.1 mg morphine, with an earlier recovery of sensory and motor functions after surgery.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative analgesia after total-hip arthroplasty: Comparison of intravenous patient-controlled analgesia with morphine and single injection of femoral nerve or psoas compartment block. a prospective, randomized, double-blind study.
The authors compared the analgesic effects and quality of rehabilitation of three analgesic techniques after total-hip arthroplasty in a double-blind, randomized trial. ⋯ PCA is an efficient and safe analgesia technique. FNB and PCB should not be used routinely after total-hip arthroplasty.
