Ultrasound-guided neuraxial block

BACKGROUND: Surgeon-administered transversus abdominis plane block is a contemporary approach to providing postoperative analgesia, and this approach is performed by transperitoneally administering local anesthetic in the plane between the internal oblique and transversus abdominis muscles to target the sensory nerves of the anterolateral abdominal wall. Although this technique is used in many centers, it has not been studied prospectively in patients undergoing a midline laparotomy. OBJECTIVE: This study aimed to evaluate whether surgeon-administered transversus abdominis plane block reduces postoperative opioid requirements and improves clinical outcomes...

The erector spinae plane (ESP) block is a relatively novel regional anesthetic technique first described in 2016. There are limited data regarding its use in pediatric surgeries although ESP blocks can likely be safely used to provide effective postoperative analgesia for major thoracic and abdominal surgeries, especially in cases where neuraxial anesthesia is contraindicated. In this report, we describe a case in which bilateral lower thoracic erector spinae plane blocks were performed in a pediatric patient with vertebral anomalies undergoing posterior sagittal anorectoplasty and reconstruction of cloacal malformation...

Fascial plane blocks are useful for multimodal analgesia after cardiac surgery since they can provide effective analgesia without the serious risks associated with conventional techniques such as neuraxial hematoma and pneumothorax. This narrative review covers blocks performed at the parasternal intercostal, interpectoral, pectoserratus, serratus anterior, erector spinae, and retrolaminar planes, which are targets for fascial plane blocks in cardiac surgery. Brief anatomical considerations, mechanisms, and currently available evidence are reviewed...

Bariatric surgeries are effective long-term management for morbid obesity with its adverse sequelae. Anesthesia of bariatric surgeries poses unique challenges for the anesthesiologist in every step starting with vascular access till tracheal extubation. The usage of ultrasound in anesthesia is becoming more prevalent with a variety of benefits, especially in the obese population. Ultrasound is successfully used for obtaining vascular access, with more than 15 million catheters placed in the United States alone...

Perioperative analgesia plays an important role in thoracic surgery, regarding not only patient satisfaction, but also in preventing postoperative complications such as pneumonia. Ultrasound-guided thoracic wall blocks close the gap between opiate based and neuraxial pain management concepts.The following article explores the different ultrasound-guided approaches to anesthetize the thoracic wall, ranging from the ventral blocks such as parasternal or PECS I/II, followed by the lateral blocks (i.e. serratus anterior), up to the dorsal approaches including the paravertebral, erector spinae plane, and retrolaminar block...

STUDY OBJECTIVES: To develop evidence-based recommendations for prevention and management of infections, bleeding, and local anesthetic toxicity in children undergoing regional anesthesia. DESIGN: A joint committee of the European Society of Regional Anesthesia and Pain Therapy (ESRA) and the American Society of Regional Anesthesia and Pain Medicine (ASRA) studied electronic literature databases of pediatric regional anesthesia to construct evidence-based recommendations...

Vascular access formation surgery for renal replacement therapy can be performed under local, regional or general anaesthesia. Regional anaesthesia may offer several advantages, however the sensory innervation to the upper medial arm can be difficult to adequately block. We describe a novel regional anaesthetic technique using both supraclavicular brachial plexus and paravertebral blocks for a multimorbid 73-year-old woman undergoing brachioaxillary fistula formation with a synthetic graft. An ultrasound-guided supraclavicular brachial plexus block was performed, followed by an ultrasound-guided T2/3 level paravertebral block...

BACKGROUND: Bleeding is a potential complication after neuraxial and peripheral nerve blocks. The risk is increased in patients on antiplatelet and anticoagulant drugs. This joint guideline from the European Society of Anaesthesiology and Intensive Care and the European Society of Regional Anaesthesia aims to provide an evidence-based set of recommendations and suggestions on how to reduce the risk of antithrombotic drug-induced haematoma formation related to the practice of regional anaesthesia and analgesia...

BACKGROUND AND AIMS: Perfusion index (PI) is a new simple, objective and non-invasive method for evaluation of the success of central neuraxial and peripheral nerve blocks. So, we conducted a study with an aim to evaluate PI as an indicator for success of ultrasound-guided supraclavicular block (SCB). METHODS: 65 patients of either sex, age 18-60 years, American Society of Anesthesiologists physical status I and II posted for upper limb surgery under ultrasound (US)-guided SCB were included...

Conducting spinal anaesthesia in patients with elevated body mass index is commonly difficult, yet there are no guidelines to direct best practice. Landmark techniques are sometimes insufficient, leading to increased failure rates and suboptimal patient outcomes. Although ultrasound-guided techniques are now considered standard care for central venous access and regional anaesthesia, there has been relatively sparse uptake of this widely available resource for central neuraxial block, despite evidence of its efficacy...

BACKGROUND AND AIMS: Caudal epidural and ultrasound-guided ilioinguinal, iliohypogastric nerve (IL/IH) blocks are commonly used regional anesthesia techniques for postoperative analgesia in pediatric inguinal surgeries. Dexmedetomidine as an adjuvant has been proven to prolong the duration of both neuraxial and peripheral nerve blocks. We compared the duration of analgesia provided by local anesthetic (LA) and dexmedetomidine for caudal and IL/IH block for pediatric inguinal surgeries...

BACKGROUND: Traditional landmark-guided spinal anesthesia can be challenging in elderly patients with hip fractures. Ultrasound assistance (USAS) and real-time ultrasound guidance (USRTG) techniques can facilitate lumbar neuraxial blocks. However, it remains undetermined which method is optimal for use in elderly patients. This study aimed to evaluate which technique was associated with a higher success rate of spinal anesthesia in elderly patients with hip fractures: USAS or USRTG technique...

BACKGROUND: Breast cancer surgery is associated with considerable acute post-surgical pain and restricted mobility. Various regional and neuraxial anesthesia techniques have been used to alleviate post-mastectomy pain. Ultrasound-guided serratus anterior plane block (SAPB) has been considered a simple and safe technique. This randomized control study was performed to compare the efficacy of SAPB with the thoracic paravertebral block (TPVB) for postoperative analgesia after breast cancer surgery...

BACKGROUND: Major hip surgery usually requires neuraxial or general anesthesia with tracheal intubation and may be supplemented with a nerve block to provide intraoperative and postoperative pain relief. CASE SUMMARY: This report established that hip surgical procedures can be performed with a fascia iliaca compartment block (FICB) and monitored anesthesia care (MAC) while avoiding neuraxial or general anesthesia. This was a preliminary experience with two geriatric patients with hip fracture, American Society of Anesthesiologists status III, and with many comorbidities...

CONTEXT: The supraclavicular brachial plexus block is a very safe, useful and effective method for upper limb surgeries. Among local anesthetics, ropivacaine has special applications in neuraxial and peripheral nerve blocks due to its low cardiotoxicity and less toxicity to central nervous systems compared to bupivacaine and lignocaine. Dexmedetomidine is a newer and potent alpha-2 receptor agonist which has 10 times higher selectivity for alpha-2 receptors as compared to clonidine, So far, very few studies have been undertaken to compare the efficacy of clonidine and dexmedetomidine to provide and prolong postoperative analgesia, especially with the use of ultrasound for nerve localization...

OBJECTIVES: Chest wall blocks are an effective strategy for postoperative pain control in minimally invasive cardiac surgery, but, in the absence of clinical trials evaluating their safety in the presence of anticoagulant and antiplatelet drugs, it still is recommended to follow the same guidelines developed for the neuraxial procedures and for peripheral blocks. DESIGN: Retrospective observational study. SETTING: AOU Città della Salute e della Scienza di Torino, University of Turin, Italy...

Surgery for hip fractures should be performed within 48 h from patient's admission. However, several factors including chronic antiplatelet therapy could delay operation. Among the totality of patients taking clopidogrel, up to 30% are resistant to the drug and have a normal platelets reactivity. We propose thromboelastography (TEG) with an ADP Platelet Mapping assay kit to assess platelet aggregation, a safe tool that could help to avoid surgery delay in those patients treated with antiplatelet therapy. A patient's blood sample was collected for aggregometry...

BACKGROUND: Infraclavicular brachial plexus nerve block is a commonly performed anesthesiology technique in the upper extremity. Local anesthetics may be administered at different temperatures for both neuraxial and peripheral nerve blocks. We aimed to evaluate the effects of the temperature of the local anesthetic at the time of administration on the onset and duration of sensory and motor blocks in infraclavicular brachial plexus nerve block. METHODS: A total of 80 patients undergoing elective upper extremity surgery were randomly assigned to one of the following groups using a computer-based randomization software; low temperature (4 °C) (Group L, n = 26), room temperature (25 °C) (Group R, n = 27) and warmed (37 °C) (Group W, n = 27)...

With the advent of fast-track pathways after cardiac surgery, there has been a renewed interest in regional anesthesia due to its opioid-sparing effect. This paradigm shift, looking to improve resource allocation efficiency and hasten postoperative extubation and mobilization, has been pursued by nearly every specialty area in surgery. Safety concerns regarding the use of classical neuraxial techniques in anticoagulated patients have tempered the application of regional anesthesia in cardiac surgery. Recently described ultrasound-guided thoracic wall blocks have emerged as valuable alternatives to epidurals and landmark-driven paravertebral and intercostal blocks...

Lung transplant recipients are at particular high risk for postoperative respiratory failure as a result of poorly controlled pain, inadequate graft expansion, decreased cough, and reliance on systemic opioid therapy. Thoracic epidural and paravertebral blocks have been employed with the goal of improving postoperative pain control, improving pulmonary mechanics, and limiting the need for narcotic administration. These approaches require a needle position in proximity to the neuraxis and may cause significant hypotension that is poorly tolerated in transplant patients...
