Randomized Controlled Trial Clinical Trial
Femoral nerve block for total knee arthroplasty patients: a method to control postoperative pain.
This study was designed to determine the effects of a single-injection femoral nerve block (FNB) using 30 mL of 0.5% bupivacaine with epinephrine 1:200,000, on pain control following total knee arthroplasty (TKA). Forty patients were randomly distributed into 2 groups: Group A received general anesthesia plus a FNB (n = 19), whereas Group B received general anesthesia plus a FNB with 30 mL of preservative-free saline (n = 21). The amount of morphine used, sedation, and average pain perception were measured for the first 24 hours and daily postoperatively. ⋯ The average pain perception was significantly different (P =.002). Postoperative management of pain following TKA can be improved through a preoperative single-injection FNB with 0.5% bupivacaine plus epinephrine 1:200,000. The cost is minimal, risks appear acceptable, and the procedure is efficacious.

Multicenter Study Clinical TrialRopivacaine in neonates and infants: a population pharmacokinetic evaluation following single caudal block.
The aims of this study were to evaluate pharmacokinetics, efficacy and safety of ropivacaine in infants aged 0-12 months following a single caudal injection. ⋯ Following a caudal block with ropivacaine 2 mg x kg(-1) plasma concentrations of unbound ropivacaine were well below threshold levels for toxicity in adults. Apparent volume of distribution is unchanged, apparent unbound clearance increases and the terminal half-life decreases with age in 0-12-month-old neonates and infants. The postoperative pain management provided adequate analgesia and was well tolerated.

Randomized Controlled Trial Comparative Study Clinical TrialSciatic nerve block with lateral popliteal approach for hallux vagus correction. Comparison between 0.5% bupivacaine and 0.75% ropivacaine.
In this study the authors compared the clinical profile of 2 local anesthetic drugs in the sciatic nerve block used during hallux valgus correction, a surgical procedure known to be post-operatively extremely painful. Since hallux valgus correction is painful post-operatively, many attempts have been tried to ensure a long-lasting analgesia. Block of the sciatic nerve appears to be the right choice balancing ease to performance, satisfaction of the patient and duration of action. ⋯ Patient satisfaction was high in both groups.

Randomized Controlled Trial Clinical Trial
Epidural infusion or combined femoral and sciatic nerve blocks as perioperative analgesia for knee arthroplasty.
Peripheral neural blockade appears to provide effective analgesia with potentially less morbidity than central neuraxial techniques. We compared the relative benefits of combined femoral (3-in-1) and sciatic nerve block with epidural blockade for postoperative knee arthroplasty analgesia. ⋯ Combined femoral (3-in-1) and sciatic blocks offer a practical alternative to epidural analgesia for unilateral knee replacements.

Comparative Study Clinical Trial Controlled Clinical Trial[Effectiveness of interscalene plexus block for open subacromion decompression].
The aim of this study was to assess the influence of interscalene brachial plexus blocks on the functional outcome, subjective pain appraisal and patient satisfaction after open shoulder surgery. These results were compared with patients treated by conventional analgesic measures. ⋯ By implementing ISB sufficient analgesia in the early postoperative period after open shoulder surgery is attained, allowing for early physiotherapy. This positively influences convalescence and the outcome of the surgical procedure. Furthermore, patients are visibly more satisfied with the postoperative pain management.
