We deal with an important problem in the field of anesthesiology known as automatic segmentation of nerve structures depicted in ultrasound images. This is important to aid the experts in anesthesiology, in order to carry out Peripheral Nerve Blocking (PNB). Ultrasound imaging has gained recent interest for performing PNB procedures since it offers a non-invasive visualization of the nerve and the anatomical structures around it. However, the location of these nerves in ultrasound images is a difficult task for the specialist due to the artifacts (i...

BACKGROUND: The in-plane lateral to medial approach is a standard technique for ultrasound-guided femoral nerve block (USG-FNB). The first bifurcation of the femoral artery, which consists of the deep artery of the thigh (DAT) or occasionally the lateral circumflex femoral artery (LCFA), is regarded as the distal border for this procedure. We sometimes detect arteries along the estimated needle trajectory for USG-FNB. The superficial (SCIA) and deep (DCIA) circumflex iliac arteries run laterally parallel to the inguinal ligament from the femoral or external iliac artery...

BACKGROUND: Perioperative care for patients undergoing carotid endarterectomy (CEA) often presents a challenge to the anesthesia provider, as this patient group commonly suffers from a wide range of comorbidities. Although clinical trials could not demonstrate a significant benefit associated with regional anesthesia for outcomes such as insult, cardiac infarction or mortality, many authors concur that regional anesthetic techniques might be preferential in specific patient populations for this type of surgery...

This study evaluated the incidence of nerve puncture and intraneural injection based on the needle approach to the nerve (direct vs. tangential). Two expert operators in regional anaesthesia performed in-plane ultrasound-guided nerve blocks (n = 158) at different levels of the brachial plexus in cadavers, aiming either directly for the nerve (n = 77) or tangentially inferior to the nerve (n = 81). After reaching the outer limit of the nerve, the needle was intentionally advanced approximately 1 mm in both approaches, and 0...

The America Society of Anesthesiology guidelines recommend multimodal analgesia that combines regional anesthetic techniques with pharmacotherapy to improve peri-procedural pain management and reduce opioid related complications. Commonly performed emergency procedures of the upper extremity such as fracture and dislocation reduction, wound debridement, and abscess incision and drainage are ideal candidates for ultrasound-guided (USG) regional anesthesia of the brachial plexus. However, adoption of regional anesthesia by emergency practitioners has been limited by concerns for potential complications and perceived technical difficulty...

Sonographic-guided tibial nerve block allows for rapid anesthetization of the heel and plantar regions of the foot. We describe a variant technique for tibial nerve regional anesthesia utilizing perineural injection of the medial plantar nerve proximal to the sustentaculum tali where the nerve is superficial and readily accessed, with resultant retrograde flow of local anesthetic proximally. Perineural injection of the medial plantar nerve at the inframalleolar level provides a simple, safe, and effective alternative method to achieve tibial nerve block for regional anesthesia in a variety of procedures...

Regional and neuraxial anesthesia for pain management after breast surgery is not widely used despite data showing improved postoperative pain control and patient satisfaction scores. We report a case of a 61-year-old woman who underwent bilateral mastectomies, and received postoperative analgesia via pectoral nerves 1 and 2 nerve blocks. This case highlights a previously undescribed technique of prolonged postoperative pain control by intraoperative placement of pectoral nerves 1 and 2 regional anesthesia catheters under direct visualization...

BACKGROUND: Pain is a major limiting factor in patient's recovery from major thoracic surgical procedures. Thoracic epidural analgesia (TEA), the current gold standard of perioperative management, has contraindications, can technically fail, and carries a risk of complications such as epidural abscess and spinal hematoma. The ultrasound-guided serratus anterior plane (SAP) block is a promising regional analgesia technique. OBJECTIVES: Since the anatomic space involved in the SAP block corresponds to the area exposed by the surgeon during right posterolateral thoracotomy, we investigated the feasibility of a "surgically guided" continuous SAP block as an alternative to TEA in selected esophagectomy patients...

Meralgia paresthetica (MP) is an entrapment neuropathy of the lateral femoral cutaneous nerve (LFCN). There are many variations in the course of the LFCN. A 55-year-old woman presented with pain and tingling sensations on the anterolateral aspect of her left thigh. Physical examination revealed hypoesthesia of the proximal anterolateral thigh on the left side. During the electrodiagnostic study, sensory nerve action potential of the LFCN could not be obtained on both sides. Through those clinical and electrophysiological findings, we prediagnosed the case as MP and planned to perform diagnostic nerve block...

In recent years, brachial plexus anesthesia techniques for upper limb surgery have been used more and more commonly on children; however, the patient is typically under deep sedation or general anesthesia. For eligible, cooperative children, surgery can also be performed using regional blocks while the patient is awake. We present 5 cases in which Ultrasound (US)-guided infraclavicular brachial plexus blocks (ICB) were used on children for hand or forearm surgery. Surgical anesthesia was achieved in all patients and surgery was completed uneventfully using brachial plexus anesthesia, without need for deep sedation...

BACKGROUND AND AIMS: The cost effectiveness of ultrasound-guided regional anesthesia is an issue which requires discussion. Based on our experience, we hypothesized that this is an economically viable option. MATERIAL AND METHODS: In this retrospective study, we included 90 patients who underwent upper extremity surgeries in our institute solely under ultrasound (USG)-guided brachial plexus blocks in a year. The cost of the block was derived by adding the cost of the material and drugs used for the block...

The stellate ganglion is a common target to manage neuropathic pain in the upper extremities. However, the effect duration of a single stellate ganglion block is often temporary. To overcome the short-term effects of a single sympathetic block, pulsed radiofrequency (PRF) can be applied. The aim of the present study was to investigate the efficacy of PRF on the cervical sympathetic chain under ultrasound guidance for complex regional pain syndrome (CRPS).Twelve CRPS patients who underwent PRF on the cervical sympathetic chain were enrolled in this retrospective analysis...

BACKGROUND: Lower extremity trauma during earthquakes accounts for the largest burden of geophysical disaster-related injuries. Insufficient pain management is common in disaster settings, and regional anesthesia (RA) has the potential to reduce pain in injured patients beyond current standards. To date, no prospective research has evaluated the use of RA in a disaster setting. This cross-sectional study assesses knowledge translation and skill acquisition outcomes for lower extremity RA performed with and without ultrasound guidance among a cohort of Médecins Sans Frontières (MSF) volunteers who will function as proceduralists in a planned randomized controlled trial evaluating the efficacy of RA for pain management in an earthquake setting...

INTRODUCTION: Regional anaesthesia is commonly preferred for arteriovenous fistula (AVF) creation. Previous studies suggest a shorter block duration in patients with chronic renal failure, maybe because of the changes in regional blood flow. The aim of our study was to evaluate the duration of the axillary block with 1.5% mepivacaine in patients with chronic renal failure scheduled for AVF compared with healthy controls. METHODS: Patients scheduled for AVF creation for the first time (GIRC) were included...
