1. Ultrasound-guided lower forearm median nerve block in open surgery for trigger thumb in 1- to 3-year-old children: A randomized trial. (Abstract)

Ultrasound-guided lower forearm median nerve block in open surgery for trigger thumb in 1- to 3-year-old children: A randomized trial. Trigger thumb is a common hand disability in children and is primarily treated with open surgery. A conscious median nerve block can usually meet the requirements for trigger thumb-releasing surgery in adults; however, its effectiveness in children requires further clarification. The present study aims to demonstrate whether ultrasound-guided lower forearm (...) median nerve blockade is a viable option for children undergoing open surgery for trigger thumb.A prospective randomized study was designed to compare median nerve blocks guided by ultrasonography with those guided by anatomic landmarks. Following induction of general anesthesia, the children received a median nerve block performed either by ultrasound-guided block of the lower forearm (group U) or landmark-based blocking at the proximal wrist crease level (group T) with a 0.2% ropivacaine injection

2. The use of ultrasound guidance for perioperative neuraxial and peripheral nerve blocks in children. (Abstract)

The use of ultrasound guidance for perioperative neuraxial and peripheral nerve blocks in children. The use of ultrasound guidance for regional anaesthesia has become popular over the past two decades. However, it is not recognized by all experts as an essential tool, perhaps because it is unclear whether ultrasound reduces the risk of severe neurological complications, and the cost of an ultrasound machine (USD 22,000) is substantially higher than the cost of other tools. This review (...) was published in 2016 and updated in 2019.To determine whether ultrasound guidance offers any clinical advantage when neuraxial and peripheral nerve blocks are performed in children in terms of decreasing failure rate or the rate of complications.We searched CENTRAL, MEDLINE, Embase, and two trial registers up to March 2018 together with reference checking to identify additional studies and contacted study authors to obtain additional trial information.We included all parallel randomized controlled trials

3. WITHDRAWN: Peripheral nerve blocks for postoperative pain after major knee surgery. (Abstract)

-analysis on specific types of adverse event. The numbers of studies and participants were also too few to draw conclusions on the other prespecified outcomes of: additional analgesic consumption; median time to remedication; knee range of motion; median time to ambulation; length of hospital stay; hospital costs; and participant satisfaction. There were insufficient data to compare peripheral nerve blocks and local infiltration or between peripheral nerve blocks and epidural analgesia.All (...) WITHDRAWN: Peripheral nerve blocks for postoperative pain after major knee surgery. Major knee surgery is a common operative procedure to help people with end-stage knee disease or trauma to regain mobility and have improved quality of life. Poorly controlled pain immediately after surgery is still a key issue for this procedure. Peripheral nerve blocks are localized and site-specific analgesic options for major knee surgery. The increasing use of peripheral nerve blocks following major knee

4. Readiness for Discharge After Foot and Ankle Surgery Using Peripheral Nerve Blocks: A Randomized Controlled Trial Comparing Spinal and General Anesthesia as Supplements to Nerve Blocks (Abstract)

Readiness for Discharge After Foot and Ankle Surgery Using Peripheral Nerve Blocks: A Randomized Controlled Trial Comparing Spinal and General Anesthesia as Supplements to Nerve Blocks Neuraxial anesthesia is often viewed as superior to general anesthesia but may delay discharge. Comparisons do not typically use multimodal analgesics and nerve blockade. Combining nerve blockade with general anesthesia may reduce pain, opioid consumption, and nausea. We hypothesized that general anesthesia (...) (with nerve blocks) would lead to earlier readiness for discharge, compared to spinal anesthesia (with nerve blocks).All patients underwent ambulatory foot and ankle surgery, with a predicted case duration of 1-3 hours. All patients received popliteal and adductor canal nerve blocks using bupivacaine and dexamethasone. No intraoperative opioids were administered. All patients received ondansetron, dexamethasone, ketamine, and ketorolac. Patients, data collectors, and the data analyst were not informed

Plasma concentrations of bupivacaine were no different following the blocks and were less than 0.78 μg mL-1 at all times. These results suggest that these ultrasound-guided nerve blocks do not result in potentially toxic systemic levels of local anesthetic and that their duration of action is useful for providing anesthesia (...)

A randomised controlled trial of pectoral nerve-2 (PECS 2) block vs. serratus plane block for chronic pain after mastectomy. Thoracic interfascial plane blocks are effective for post-mastectomy acute analgesia. However, their effects on chronic pain are uncertain. We randomly allocated 80 women equally to pectoral nerve-2 (PECS 2) block or serratus plane block. The pectoral nerve-2 block reduced the rate of moderate or severe chronic pain from 13/40 (33%) with the serratus plane block to 4/40

Quality of Recovery After Breast Surgery: A Multicenter Randomized Clinical Trial Comparing Pectoral Nerves Interfascial Plane (Pectoral Nerves II) Block With Surgical Infiltration. Pectoral nerves (PECS II) block is a popular regional analgesia technique for breast surgery. PECS II block or local infiltration by surgeon may improve outcomes including quality of recovery (QoR).In this multicenter randomized clinical trial, 104 female patients undergoing breast surgery received: (1) PECS II (...) block with local anesthetic and surgical infiltration with 0.9% saline (PECS group) or (2) PECS II block with 0.9% saline and surgical infiltration with local anesthetic (infiltration group). Patients, anesthetists, surgeons, nursing staff, and research assistants were blinded to group allocation. Patients received standardized general anesthesia and multimodal analgesia. The primary outcome was the global score (maximum score, 150; good recovery, 118) of the multidimensional (pain, comfort

A variation of Musculocutaneous nerve without piercing the coracobrachialis muscle while communicating to the median nerve: A case report and literature review Anatomical variations of the peripheral nervous system may have not any clinical signs and symptoms.

mechanisms underlying the effects of median nerve stimulation on hypertension were investigated via microneurography, A-fiber blocking experiments, and localized chemical or electrical stimulation. Bilateral median nerve stimulation at either low or high frequencies produced profound but transient reductions in systolic BP, which were elicited when median nerve stimulation was unilaterally applied at interelectrode distances of 2 and 4 cm. Systolic BP was also reduced by electrical stimulation (...)
