Randomized Controlled Trial Comparative Study Clinical Trial
The efficacy of femoral nerve block in pain reduction for outpatient hamstring anterior cruciate ligament reconstruction: a double-blind, prospective, randomized trial.
The purpose of this study was to assess the efficacy of intraoperative femoral nerve block (FNB) in the reduction of postoperative pain following anterior cruciate ligament (ACL) hamstring reconstruction. Patients undergoing primary ACL reconstruction with hamstring tendon graft under general anesthetic who had signed an informed consent were included in the study. Patients were stratified to 4 surgeons and randomized to FNB with 0.25% bupivacaine or placebo of normal saline injected into the femoral nerve sheath before reversal of the general anesthetic. ⋯ In conclusion, FNB may reduce pain on the night of surgery. However, this may not be clinically significant. FNB is not recommended at this time for use in outpatient ACL reconstruction with hamstring graft.

Randomized Controlled Trial Clinical Trial[Brachial plexus block. Effect of low interscalenic approach on phrenic nerve paresis].
The aim of the paper was to determine the influence of the brachial plexus block on phrenic nerves paralysis in distal side of interscalenic space (between 1/3 medium and 1/3 inferior), with little volume of local anesthetic drug. Comparative, prospective, randomized study. ⋯ Brachial plexus anesthesia by low interscalenic tract, even using little local anesthetic drug volumes, like other supraclavear block techniques determines ipsilateral diaphragm paralysis.

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of coracoid and axillary approaches to the brachial plexus.
Brachial plexus block by the coracoid approach does not require arm abduction and may be more effective than the axillary approach because of a more proximal injection of local anaesthetic. However, the clinical usefulness of the coracoid approach has not been tested in prospective controlled trials. The present randomized, observer-blinded study compared success rates, time to obtain a complete block, frequency of adverse effects and block discomfort in two groups of 30 patients, anaesthetized for hand surgery using either the coracoid or the axillary approach to the brachial plexus. ⋯ The axillary approach to the brachial plexus using four injections of ropivacaine results in a faster onset of block and a better spread of analgesia than the coracoid approach using two injections.

Randomized Controlled Trial Comparative Study Clinical TrialCombined lumbar and sacral plexus block compared with plain bupivacaine spinal anesthesia for hip fractures in the elderly.
This prospective randomized study was designed to determine the hemodynamic effects and quality of combined lumbar and sacral plexus block compared with plain bupivacaine spinal anesthesia in the elderly for repair of proximal femoral fractures. ⋯ Plain bupivacaine spinal anesthesia and combined lumbar/sacral plexus block provided adequate anesthesia for repair of hip fracture in the elderly. Hypotension was induced by both the combined peripheral nerve block and plain bupivacaine spinal anesthesia in aged patients; hypotension was found to be longer lasting after spinal anesthesia and of a larger magnitude in patients over 85 years of age.
