ultra sound guided nerve blocks

BACKGROUND: Regional anaesthesia offers the anaesthesiologist, the surgeon, as well as the patient advantages over general anaesthesia such as being conscious through the surgery, avoiding multiple drugs, better haemodynamic stability, excellent postoperative analgesia, and faster per oral consumption post surgery. Compared with the axillary approach, the brachial plexus block at the level of the clavicle can anaesthetize all four distal upper extremity nerve territories without the requirement for a separate block of the musculocutaneous nerve...

BACKGROUND: This study aimed to compare local periarticular infiltration (LIA) with ultra-sound guided regional anesthesia (USRA) with ropivacaine and dexmedetomidine as an additive agent in primary total knee arthroplasty (TKA). METHODS: Fifty patients were randomized into two groups in a 1:1 ratio. Patients in the LIA group received local periarticular infiltration into the knee joint. The USRA group received two single-shot USRA blocks. Functional outcomes and satisfaction (range of movement, Knee Society Knee Score, Western Ontario and McMaster Universities Osteoarthritis Index, Oxford Knee Score, and Forgotten Joint Score), including well-being, were analyzed preoperatively and at five days, six weeks, and one and two years postoperatively...

INTRODUCTION: This cadaveric dye study assesses the effect of volume and number of injections on the spread of solution after ultrasound-guided rectus sheath injections. In addition, this study evaluates the impact of the arcuate line on solution spread. MATERIALS AND METHODS: Ultrasound-guided rectus sheath injections were performed on seven cadavers on both sides of the abdomen, for a total of 14 injections. Three cadavers received one injection of 30 mL of a solution consisting of bupivacaine and methylene blue at the level of the umbilicus...

BACKGROUND: Interscalene block is one of the popular methods for decreasing pain and analgesic consumption after shoulder arthroscopic surgeries. OBJECTIVES: The objective is to compare the analgesic duration of effects of dexmedetomidine and dexamethasone as adjuvants to 0.5% ropivacaine in ultrasound-guided interscalene blocks for arthroscopic shoulder surgery in an ambulatory setting. METHODS: In this randomized controlled trial, 117 adult patients candidate for ambulatory arthroscopic shoulder surgery under general anesthesia were divided into three groups to perform an ultra-sound guided interscalene block before the surgery...

STUDY DESIGN: Prospective clinical pilot study and cadaveric study. OBJECTIVE: The aim of this study was to evaluate the spread of an ultrasound-guided interfascial plane blocks (UGIPBs) and its potential efficacy for cervical radiculopathy. SUMMARY OF BACKGROUND DATA: Cervical radiculopathy is a common disorder, potentially leading to severe pain and disability. Conservative treatment with cervical epidural steroid injections (ESI) is limited by concerns regarding their safety...

Marfan syndrome is an autosomal dominant connective tissue disorder with anomalies involving the musculoskeletal system, cardiovascular system, skin, eyes, and teeth. Patients with Marfan syndrome are especially prone to cardiovascular complications, which increases the risk multifold under general anesthesia. This is a case of a 37-year-old Marfan syndrome male patient with cardiac manifestations and his anesthesia course during emergency wound debridement.

: Ultrasound for diagnostic and procedural purposes is becoming a standard in daily clinical practice including anaesthesiology and peri-operative medicine. The project of European Society of Anaesthesiology (ESA) Task Force for the development of clinical guidelines on the PERioperative uSE of Ultra-Sound (PERSEUS) project has focused on the use of ultrasound in two areas that account for the majority of procedures performed routinely in the operating room: vascular access and regional anaesthesia. Given the extensive literature available in these two areas, this paper will focus on the use of ultrasound-guidance for vascular access...

INTRODUCTION: Among the elderly population, chronic osteoarthritis of the knee joint is one of the leading causes of disability and causes considerable pain, joint stiffness, and functional limitations. Although knee replacement is a good option for advanced osteoarthritis, many patients could not undergo surgery due to comorbidities or other reasons. METHODS: Four patients with severe pain from grade 3 and 4 osteoarthritis of the knee had undergone ultrasound-guided alcohol neurolysis of the 6 genicular nerves after a positive genicular nerve block with local anesthetics...

Pain is the most feared symptom of cancer. New oncological cancer treatments are improving survival, but advanced cancer presents challenges that have not been seen before, often with pain that is very difficult to manage because of a recurrent tumour that is invading the central nervous system. In some of the older interventional techniques of destroying nerve pathways, expertise has diminished or has been deemed unnecessary with the development of specialist palliative care. Not all pain is managed adequately with the analgesic ladder...
