Case Reports[Acute toxic accident following lumbar plexus block with bupivacaine].
We report the case of a patient who experienced ventricular dysrhythmias and seizure five minutes after the injection of 30 mL of 0.5% bupivacaine with 1:200,000 epinephrine, during a lumbar plexus block performed via the posterior approach described by Winnie. The patient who underwent his total hip arthroplasty was still anaesthetised and under controlled ventilation at the time of bupivacaine administration. ⋯ Normal cardiac activity and stable haemodynamic condition were restored after one hour of resuscitation including 15 electric shocks and administration of epinephrine (40 mg) and clonidine (300 micrograms). The patient was discharged without neurologic sequelae after four days in the ICU.

Clinical TrialCT-guided celiac plexus block for intractable abdominal pain.
Treatment of intractable abdominal pain due to inoperable intraabdominal malignancy is important, and the ineffectiveness of pharmacological agents has led many investigators to recommend chemical neurolysis of the celiac ganglions as a treatment. The author describes the technique and results of celiac plexus neurolysis under CT-guidance with various approach routes, including anterior, posterior and transaortic routes. Twenty-eight patients, ranging in age from 36 to 82 years, have been treated with this procedure. ⋯ Mild hypotension occurred in five patients (18%) and transient diarrhea in six patients (21%). Twenty-one (75%) of the 28 patients had some relief of pain and 17 of these patients (61%) had good relief of pain after the procedure. The results support that CT-guided celiac plexus block with alcohol is a safe and effective means of pain control in patients with intraabdominal malignancy.

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 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.
