Defining the cross-sectional anatomy important to interscalene brachial plexus block with magnetic resonance imaging.
Interscalene brachial plexus block is a useful technique to provide anesthesia and analgesia for the shoulder and proximal upper extremity. The initial needle direction at the interscalene groove has been described as being "perpendicular to the skin in every plane" (1). A cross-sectional (axial) approach may offer a more easily conceptualized directed needle placement. The purpose of this study is to define the cross-sectional anatomy and idealized needle angles important to interscalene brachial plexus block. ⋯ These findings suggest initial needle placement at the interscalene groove should be angled less perpendicularly relative to the sagittal plane than is often observed. A cross-sectional approach enables more practical visualization of initial needle placement. A more accurate initial needle placement may minimize the number of needle passes necessary to contact the nerve roots, thereby more efficiently obtaining a successful block.

Randomized Controlled Trial Comparative Study Clinical Trial[Brachial plexus anesthesia via an axillary route for emergency surgery: comparison of three approach methods].
To compare three techniques of brachial plexus blockade for emergency surgery of the upper limb. ⋯ As these three techniques for brachial plexus block in emergency surgery are comparable, no one can be recommended instead of the others.

Randomized Controlled Trial Comparative Study Clinical TrialCardiovascular effects of two different regional anaesthetic techniques for unilateral leg surgery.
Cardiovascular function was assessed in 20 ASA I-II patients, scheduled for elective orthopaedic surgery with tourniquet in order to compare the haemodynamic changes induced by unilateral spinal anaesthesia and combined sciatico-femoral nerve block. ⋯ Both sciatico-femoral and unilateral spinal blockade provide adequate anaesthesia for unilateral leg surgery with tourniquet. The former technique affects cardiovascular performance less than the latter one.

Randomized Controlled Trial Clinical TrialBupivacaine infiltration into the neurovascular bundle of the prostatic nerve does not improve postoperative pain or recovery following transvesical prostatectomy.
We assessed the effect of intraoperative bupivacaine infiltration into the neurovascular bundle of the prostatic nerve on postoperative pain and patient outcome. ⋯ Following transvesical prostatectomy, prostatic nerve blockade has no beneficial effects on postoperative pain or patient outcome.

Randomized Controlled Trial Clinical Trial
Postoperative analgesia with "3-in-1" femoral nerve block after prosthetic hip surgery.
To evaluate the efficacy of a single shot "3-in-1" femoral nerve block for prosthetic hip surgery in association with general anaesthesia on post-operative analgesia. ⋯ There is a short-term benefit during the first few postoperative hours in using a single shot "3-in-1" femoral nerve block to complement general anaesthesia for elective hip surgery.
