Randomized Controlled Trial Comparative Study Clinical TrialRopivacaine 7.5 mg/ml versus bupivacaine 5 mg/ml for interscalene brachial plexus block--a comparative study.
We investigated ropivacaine 75 mg/ml in comparison with bupivacaine 5 mg/ml in patients receiving interscalene brachial plexus block (ISB) and general anaesthesia. In this randomized, double-blind, prospective clinical trial, each patient received an ISB block according to the technique originally described by Winnie and a catheter technique as per Meier. The rapidity of onset and the quality of sensory and motor block were determined. ⋯ There were no significant differences in terms of onset and quality of sensory or motor block during the intraoperative and early postoperative period. In addition we did not identify any side-effects related to the administration of the local anaesthetics. Ropivacaine 7.5 mg/ml and bupivacaine 5mg/ml proved to be nearly indistinguishable when administered for interscalene brachial plexus block.

ReviewParavertebral anaesthesia/analgesia for ambulatory surgery.
For many years, paravertebral nerve blockade has been an established technique for providing analgesia to the chest and abdomen. The current emphasis on containment of health care costs has resulted in a rediscovery of anaesthetic techniques, such as paravertebral blocks, that facilitate outpatient surgical management and promote early discharge. ⋯ Continuous paravertebral catheters, pharmacological agents used in PVB, and single versus multiple injection paravertebral block techniques are also covered. Specific clinical situations that are particularly well suited to the application of PVB as the primary anaesthetic in the ambulatory setting and other clinical situations where analgesia from PVB is efficacious are discussed.

Randomized Controlled Trial Comparative Study Clinical Trial
Patient-controlled regional analgesia (PCRA) at home: controlled comparison between bupivacaine and ropivacaine brachial plexus analgesia.
The aim of this randomized, double-blinded study was to compare the analgesic efficacy of bupivacaine versus ropivacaine brachial plexus analgesia after ambulatory hand surgery. An additional aim was to study the feasibility and safety of patient-controlled regional analgesia (PCRA) outside the hospital. ⋯ This double-blinded study has demonstrated the feasibility of self-administration of local anesthetic to manage postoperative pain outside the hospital. Ropivacaine and bupivacaine provided effective analgesia, and patient satisfaction with PCRA was high. Patient selection, follow-up telephone call, and 24-h access to anesthesiology services are prerequisites for PCRA at home.

We describe a simple technique to deliver local anaesthetic for percutaneous testis biopsies. ⋯ Intra-testicular lidocaine appears to be a simple, rapid and safe method to provide anaesthesia for a percutaneous testis biopsy.

Randomized Controlled Trial Clinical Trial
Lumbar paravertebral nerve block in the management of pain after total hip and knee arthroplasty: a randomized controlled clinical trial.
The accepted mode of pain management after total hip or knee arthroplasty is patient-controlled analgesia. This study evaluates the efficacy of lumbar paravertebral nerve block in diminishing postoperative pain when used as an adjunct to patient-controlled analgesia. A total of 115 arthroplasty patients received postoperatively a lumbar paravertebral nerve block (block, n = 57) or a sham procedure (control, n = 58). ⋯ Visual analog scale pain score measurements at 4, 8, and 24 hours did not differ significantly between the groups. Paravertebral nerve block of the lumbar plexus is an invasive procedure with some risk. Considering the added risk and minimal benefits, routine use of this procedure is not supported.
