INTRODUCTION: Anterior cutaneous nerve entrapment syndrome (ACNES) is an underrecognized etiology of chronic abdominal pain that causes great morbidity to those affected. We sought to determine the outcome of neurectomy for ACNES in children. METHODS: Demographic and clinical data on children who underwent neurectomy for ACNES by a single surgeon from 10/2011 to 01/2017 were reviewed. RESULTS: Twenty-six patients underwent neurectomy for ACNES...

BACKGROUND: In recent years, thoracic wall nerve blocks, such as the pectoral nerve (PECS) block and the serratus plane block have become popular for peri-operative pain control in patients undergoing breast cancer surgery. The effect of PECS block on quality of recovery (QoR) after breast cancer surgery has not been evaluated. OBJECTIVES: To evaluate the ability of PECS block to decrease postoperative pain and anaesthesia and analgesia requirements and to improve postoperative QoR in patients undergoing breast cancer surgery...

BACKGROUND AND AIM: 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. METHODS: A prospective randomized study was designed to compare median nerve blocks guided by ultrasonography with those guided by anatomic landmarks...

The general microscopic characteristics of nerves are described in several textbooks of histology, but the specific microanatomies of most nerves that can be blocked by anesthesiologists are usually less well known. Our objective was to evaluate the 3D reconstruction of nerve fascicles from optical projection tomography images (OPT) and the ability to undertake an internal navigation exploring the morphology in detail, more specifically the fascicular interconnections. Median and lingual nerve samples were obtained from five euthanized piglets...

OBJECTIVE: Anterior cutaneous nerve entrapment syndrome (ACNES) is often an overlooked cause of abdominal pain. Data for pediatric patients, especially regarding the treatment modalities are scarce. The aim of this study is to present a treatment modality of ACNES with combined local subfascial anesthetic and corticosteroid injection in a prospectively collected cohort of pediatric patients. METHODS: This was a prospective observational long-term study, which included pediatric patients who were diagnosed with ACNES in a tertiary care pediatric center and followed up for at least 12 months (median 1...

The goal of this study was to capture the electroencephalographic signature of experimentally induced pain and pain-modulating mechanisms after painful peripheral electrical stimulation to determine one or a selected group of electrodes at a specific time point with a specific frequency range. In the first experiment, ten healthy participants were exposed to stimulation of the right median nerve while registering brain activity using 32-channel electroencephalography. Electrical stimulations were organized in four blocks of 20 stimuli with four intensities - 100%, 120%, 140%, and 160% - of the electrical pain threshold...

Objective: To investigate the median effective dose (ED(50)) of hydromorphone and the appropriate concentration of ropivacaine combined with hydromorphone in epidural labor analgesia. Methods: One hundred and forty nulliparous women undergoing labor selected for delivery with epidural analgesia were enrolled in our hospital from January to June 2016. The first of top 50 women received 0.12% ropivacaine plus 20 μg/ml hydromorphone complex solution, then sequential women were used the modified sequential method to determine the ED(50) and ED(95) of hydromorphone...

Background: Pectoral nerve block1 (PEC1) given between pectoralis major and minor, and modified pectoral nerve block2 (mPEC2) performed between pectoralis minor and serratus anterior, can provide continuous analgesia after modified radical mastectomy (MRM) when catheters are placed before skin closure. This study was designed to compare PEC1 and mPEC2 block for providing postoperative pain relief after MRM. Methods: Sixty-two physically fit patients undergoing MRM were assigned into two groups (Group PEC1, n=31 and Group mPEC2, n=31)...

Objective: In this study, we aimed to compare axillary brachial plexus block using the two-injection and four-injection techniques assisted with ultrasonography (USG) and nerve stimulator in patients operated for carpal tunnel syndrome with articaine. To evaluate which technique is more effective, we compared the onset time, effectiveness, and duration of block procedures, patient satisfaction, adverse effect of the drug, and complication rates of the motor and sensory blocks. Methods: Sixty patients were randomly divided into two groups...

Acute inflammatory demyelinating polyradiculoneuropathy (AIDP) and acute motor axonal neuropathy are the most common variants of Guillian-Barre syndrome documented in the Asian population. However, the variability of early neurophysiologic findings in the Asian population compared to western data has not been documented. Eighty-seven cases of AIDP were retrospectively reviewed for their demographic, clinical, electrophysiological, and laboratory data. Mean age of subjects was 31 ± 8 years with males more commonly affected...

PURPOSE: Microsurgical denervation of the spermatic cord (MDSC) is a treatment option for chronic orchialgia that is refractory to conservative treatment. A recent study has shown specific nerve fibers as the possible cause of chronic orchialgia. Our goal was to present outcomes of ligation of these nerves using a targeted robotic assisted microsurgical denervation of the spermatic cord (TRMDSC) technique. METHODS AND MATERIALS: Retrospective review of 872 cases (772 patients) who underwent TRMDSC from Oct 2007 to July 2016...

Although total knee arthroplasty (TKA) is a commonly performed procedure, anesthetic efficacy in post-surgical pain remains an issue. Exparel (45mM liposome bupivacaine), a relatively long-acting local anesthetic, has shown efficacy in blocking peripheral nerve or periarticular infiltration to achieve better post-TKA analgesia. In the present work, we tested whether a fixed-dose combination of QX-OH (35mM) and levobupivacaine (10mM) (QX-OH/LB) could confer longer-lasting pain relief and reduce periarticular tissue toxicity compared to liposome bupivacaine (45mM) after TKA operation...

Here is described a successful perioperative pain control with continuous median nerve block after flexor tendon repair surgery on 2nd finger of a child. A 9-year-old patient was admitted for reconstruction surgery. The combination of median nerve block and lateral/medial antecubital cutaneous nerve blocks were performed before the surgery to cover all the surgical incision including the 2nd finger, palm, the graft site proximal to the wrist, and Kleinert traction at the nail bed. At the end of the surgery, the infusion catheter was inserted at the distal one-third to spare the muscle strength of flexor digitorum muscles...

BACKGROUND: The cluster approach for supraclavicular brachial plexus block (SC-BPB) can be easily performed but may result in asymmetric local anesthetic (LA) spread. The authors hypothesized that the use of a cluster approach in each of the 2 planes would achieve better 3-dimensional LA distribution than the traditional single cluster approach. OBJECTIVES: The purpose of the present study was to compare a double injection (DI) in 2 planes (one injection in each plane) with the traditional single injection (SI) cluster approach for ultrasound-guided SC-BPB...

BACKGROUND: Traumatic injury of the femur resulting in femoral fracture may result in significant postoperative pain. As with other causes of acute pain, regional anesthesia may offer a benefit over conventional therapy with intravenous opioids. This study prospectively assesses the effects of femoral nerve blockade with a lateral femoral cutaneous nerve block (FN-LFCN) on intraoperative anesthetic requirements, postoperative pain scores, and opioid requirements. MATERIALS AND METHODS: Seventeen pediatric patients (age 2-18 years) undergoing surgical repair of a traumatic femur fracture fulfilled the study criteria and were randomly assigned to general anesthesia with either an FN-LFCN block (n = 10) or intravenous opioids (n = 7)...
