A randomized comparison between Accuro and palpation-guided spinal anesthesia for obese patients undergoing orthopedic surgery.
Although obese patients benefit from neuraxial anesthesia, technical difficulties often discourage its use. The current randomized trial compared Accuro, a hand-held, battery-operated ultrasound (US) device, and conventional palpation for spinal anesthesia in obese patients undergoing orthopedic surgery. We hypothesized that Accuro would decrease the number of needle redirections. ⋯ The use of Accuro reduced the number of needle redirections and passes through the skin when performing spinal anesthesia, but required a longer procedural time.

ReviewA review of peripheral nerve blocks for cesarean delivery analgesia.
Peripheral nerve blocks have a unique role in postcesarean delivery multimodal analgesia regimens. In this review article, options for peripheral nerve blocks for cesarean delivery analgesia will be reviewed, specifically paravertebral, transversus abdominis plane, quadratus lumborum, iliohypogastric and ilioinguinal, erector spinae, and continuous wound infiltration blocks. Anatomy, existing literature evidence, and specific areas in need of future research will be assessed. Considerations for local anesthetic toxicity, and for informed consent for these modalities in the context of emergency cesarean deliveries, will be presented.

Anterior quadratus lumborum block analgesia for total hip arthroplasty: a randomized, controlled study.
Quadratus lumborum (QL) block is a new regional analgesic technique for upper and lower abdominal surgeries as part of a multimodal analgesic regime. It has also been reported to relieve pain after total hip arthroplasty (THA). In this prospective, randomized, double-blind study, we compared QL block with control (no block) in patients undergoing primary THA. ⋯ Our preliminary data show that the QL block provided effective analgesia and decreased opioid requirements up to 48 hours after primary THA.

The serratus plane block for postoperative analgesia in breast and thoracic surgery: a systematic review and meta-analysis.
The serratus plane block (SPB) is a novel chest wall interfascial plane block. Its analgesic efficacy compared with non-block care and paravertebral block (PVB) is unestablished. ⋯ SPB reduced postoperative pain scores (Grading of Recommendations Assessment, Development, and Evaluation rating: low; due to heterogeneity and deficiencies in blinding) in breast and thoracic surgery patients compared with non-block care. Based on five trials only, SPB was not appreciably different from PVB.
