Randomized Controlled Trial Comparative StudyDoes the addition of magnesium to bupivacaine improve postoperative analgesia of ultrasound-guided thoracic paravertebral block in patients undergoing thoracic surgery?
Magnesium is a plentiful intracellular cation that has been reported to possess analgesic effect. The present study was aimed to see whether addition of magnesium to bupivacaine in thoracic paravertebral block (TPVB) improved the analgesic effect after thoracic surgery. ⋯ Addition of magnesium to bupivacaine in TPVB improved the analgesic effect of bupivacaine in patients undergoing thoracic surgery.

Randomized Controlled Trial Comparative StudyEffective analgesia with ultrasound-guided interscalene brachial plexus block for postoperative pain control after arthroscopic rotator cuff repair.
Ultrasound (US)-guided continuous interscalene brachial plexus block (CBPB) is known to provide effective pain relief for arthroscopic rotator cuff repair. This study was conducted to compare analgesic efficacy and forearm muscle tone of the basal infusion rate and bolus dose of 0.2 % ropivacaine for US-guided CBPB with intravenous patient-controlled analgesia (IV-PCA). ⋯ The bolus dose of 0.2 % ropivacaine using US-guided CBPB would provide equivalent analgesic efficacy comparable with the basal infusion and motor weakness comparable with IV-PCA after arthroscopic rotator cuff repair.
