Ultrasound regional block

Michael J Barrington, Yoshiaki Uda
PURPOSE OF REVIEW: Ultrasound guidance has become the accepted standard of practice for peripheral regional anesthesia. Despite evidence supporting the efficacy of ultrasound-guided regional anesthesia, its impact on patient safety has been less clear. RECENT FINDINGS: Evidence has been consistent that ultrasound guidance reduces the incidence of vascular injury, local anesthetic systemic toxicity, pneumothorax and phrenic nerve block. Within the limited global scope of the epidemiology and etiologic complexity of perioperative (including block-related) peripheral nerve injury, there has not been consistent evidence that ultrasound guidance is associated with a reduced incidence of nerve injury...

Erector spinae plane block (ESPB) as postoperative analgesia method has been successfully carried out in several surgical interventions. Postoperative pain treatment for cesarean section is considered one of the important challenges for anesthesiologists due to the risk of chronic pain development and even pospartum depression. Regional anesthesia techniques were effectively used to prevent the pain together with multimodal analgesia regimes in cesarean section. Formerly, successful erector spinae plane block was documented as postoperative analgesia treatment for cesarean section; however, no motor weakness was recorded as a side effect...

Ultrasound is a real-time image modality enabling the analysis of tendon dynamics for diagnosis of carpal tunnel syndrome. Automatic tendon displacement quantification algorithms based on speckle tracking generally suffer from underestimation due to stationary background present in the tendon region. We propose an improved quantification method using Singular Value Decomposition (SVD) filtering to suppress the clutter. The accuracy of our Improved Speckle Tracking (IST) method was validated against a ground truth and compared to the accuracy of our Original Block Matching (OBM) algorithm and Commercial Tissue Tracking (CTT) software...

BACKGROUND: Despite the ultrasound guidance of transversus abdominis plane (TAP) blocks has allowed greater precision of needle placement in the desired tissue plane, visualization of the abdominal wall muscles can be hindered by morbid obesity and could lead to failed regional anesthesia. The aim of this study was to assess the feasibility and effect of laparoscopic-guided TAP block in patients undergoing Roux-en-Y gastric bypass and to compare it with port-site infiltration. PATIENTS AND METHODS: A prospective randomized clinical trial was performed...

Plane blocks have become very popular in recent years with the introduction of ultrasonography into the regional anesthesia and algology practice. Ultrasound guided erector spinae plane (ESP) block was first described in 2016. ESP block involves injection of local anesthetics between erector spinae muscles and transverse process of thoracic or lumbar vertebrae and can block the dorsal and ventral rami of thoracolumbar spinal nerves. ESP block has been successfully reported to relieve the pain of multiple rib fracture in the emergency department (ED)...

Cervical plexus block (CPB) has been used in various head and neck surgeries to provide adequate anesthesia and/or analgesia. However, it is performed in narrow space of neck area containing many sensitive structures, multiple fascial layers, and complicated nerve innervation. Since intermediate CPB was introduced in addition to superficial and deep CPBs in 2004, there has been some confusion in nomenclature and definition of CPB, particularly the intermediate CPB. Additionally, as the role of ultrasound in the head and neck region has expanded, CPB can be performed more safely and accurately under ultrasound guidance...

Background: Worldwide, breast cancer is the main common cancer among females. In the United States, it affects one in eight women during their lifespan. In breast cancer surgery, chronic pain can be developed from poorly managed acute postoperative pain. The aim of the study was to use a safe, easy, and less complicated method of regional block for reducing the postoperative pain after mastectomy, which will reduce the incidence of chronic postmastectomy pain. Materials and Methods: Ninety adult female patients with American Society of Anesthesiologists Physical Status I, II, and III were allocated randomly into three groups: Group C had general anesthesia; Group B had ultrasound-guided pectoral nerve block (PECS block) (28mL 0...

Background and Aims: The technique of percutaneous brachial plexus block has persisted in many variations since first such block given by Hirsheli in 1911.[1] Both supraclavicular and infraclavicular approaches have been described. Consequent to perivascular technique (Winnie and Collins 1964), Winnie described interscalene block (ISB) in 1970.[23] Winnie's was a single deposit block which relied upon volume for its success. It is nearly 50 years that ISB has stood the test of time and has evolved from single to multiple deposits Block...

Background Trigeminal neuralgia is a neuropathic disorder characterized by episodes of intense pain in the face. Drug therapy is the first choice of treatment. However, in cases where drug therapy are contraindicated due to side effects, patients can get pain relief from lengthy neurosurgical procedures. Alternatively, a peripheral trigeminal nerve block can be easily performed in an outpatient setting. Therefore it is a useful treatment option for the acute paroxysmal period of TN in patients who cannot use drug therapy...
