Randomized Controlled TrialNerve stimulation guided bilateral pudendal nerve block versus landmark-based caudal block for hypospadias repair in young children: a prospective, randomized, pragmatic trial.
Caudal block is frequently performed to provide analgesia for hypospadias repair. Literature suggests that pudendal block provides prolonged postoperative analgesia as compared with caudal block in children between 2 and 5 years. We compared the efficacy of pudendal and caudal blocks in children less than 2 years. ⋯ In children less than 2 years, both blocks provide comparable intraoperative and postoperative pain relief in the first 24 hours after hypospadias surgery.

Randomized Controlled TrialImpact of an extrafascial versus intrafascial injection for supraclavicular brachial plexus block on respiratory function: a randomized, controlled, double-blind trial.
Hemidiaphragmatic paresis after ultrasound-guided supraclavicular brachial plexus block is reported to occur in up to 67% of patients. We tested the hypothesis that an injection outside the brachial plexus sheath reduces the incidence of hemidiaphragmatic paresis compared with an intrafascial injection while providing similar analgesia. ⋯ Ultrasound-guided supraclavicular brachial plexus block with an extrafascial injection does not reduce the incidence of hemidiaphragmatic paresis although it provides similar analgesia, when compared with an intrafascial injection. The longer time to surgery readiness is less compatible with contemporary operating theater efficiency requirements.

Randomized Controlled TrialComparison of lateral quadratus lumborum and lumbar plexus blocks for postoperative analgesia following total hip arthroplasty: a randomized clinical trial.
Effective analgesia after total hip arthroplasty must minimize pain and optimize early ambulation. Lumbar plexus blocks (LPBs) provide analgesia but may cause motor weakness. Quadratus lumborum blocks (QLBs) may provide analgesia with preserved motor strength. ⋯ Although we were unable to demonstrate non-inferiority for opioid consumption at 12-hour postoperative, strength and mobilization were improved in lateral QLB subjects.

Randomized Controlled TrialComparison of postoperative analgesic effects of posterior quadratus lumborum block and intrathecal morphine in laparoscopic donor hepatectomy: a prospective randomized non-inferiority clinical trial.
Posterior quadratus lumborum block (QLB) and intrathecal morphine are accepted analgesic strategies in laparoscopic liver resection, but their effects have not been compared after laparoscopic donor hepatectomy. This study was planned to perform this comparison. ⋯ Bilateral posterior QLB elicited higher resting pain scores at 24-hour after laparoscopic donor hepatectomy than intrathecal morphine and did not meet the definition of non-inferiority.
