Randomized Controlled Trial Comparative Study Clinical Trial
Epidural block with ropivacaine and bupivacaine for elective caesarean section: maternal cardiovascular parameters, comfort and neonatal well-being.
To determine cardiovascular effects and neonatal outcome of ropivacaine 0.75% and bupivacaine 0.5% for elective epidural caesarean section. ⋯ Both drugs produced equally satisfactory epidural block. Although ropivacaine 0.75% resulted in a greater decrease of maternal heart rate, this effect did not influence neonatal well-being. Both ropivacaine 0.75% and bupivacaine 0.5% can therefore be recommended for epidural anaesthesia in elective caesarean section.

Randomized Controlled Trial Clinical TrialA randomized controlled trial comparing mandibular local anesthesia techniques in children receiving nitrous oxide-oxygen sedation.
The aim of this study was to test the hypothesis that dental pain control using infiltration/intrapapillary injection was less effective than inferior alveolar block/long buccal infiltration anesthesia in children. A total of 101 healthy children, aged 5-8 years, who had no contraindication for local anesthetic and who needed a pulpotomy treatment and stainless steel crown placement in a lower primary molar were studied. A 2-group randomized blinded controlled design was employed comparing the 2 local anesthesia techniques using 2% lidocaine, 1:100,000 epinephrine. ⋯ Nine percent of children required supplementary local anesthetic: 4 of 52 (7.7%) in the block/long buccal group and 5 of 49 (10.2%) in the infiltration/intrapapillary group (P = .07). The hypothesis that block/long buccal would be more effective than infiltration/intrapapillary was not supported. There was no difference in pain control effectiveness between infiltration/intrapapillary injection and inferior alveolar block/long buccal infiltration using 2% lidocaine with 1:100,000 epinephrine when mandibular primary molars received pulpotomy treatment and stainless steel crowns.

Randomized Controlled Trial Clinical Trial
[Bupivacaine for continuous interscalene brachial plexus analgesia after shoulder surgery].
This study evaluates clinical efficacy of continuous interscalene brachial plexus block with bupivacaine 0.15% for postoperative analgesia after shoulder surgery. ⋯ Continuous interscalene brachial plexus analgesia is a reliable and effective method of providing postoperative pain relief after shoulder surgery and is superior to the systemic analgesia.

Randomized Controlled Trial Comparative Study Clinical Trial
Ropivacaine plasma concentrations are similar during continuous lumbar plexus blockade using the anterior three-in-one and the posterior psoas compartment techniques.
To compare ropivacaine blood concentrations obtained after a continuous lumbar plexus block performed either by the anterior three-in-one femoral (FEM) technique or the posterior (psoas compartment; PSOAS) technique. ⋯ Although the posterior PSOAS block results in higher early plasma concentrations of local anesthetic than the anterior three-in-one FEM block, both techniques are equivalent with regards to their potential toxicity when a continuous infusion is administered. Local anesthetic accumulation occurs with an infusion of ropivacaine 0.2% at 12 mL.hr(-1) and can lead to potentially dangerous concentrations at 48 hr.
