ultrasonography neuroaxial

OBJECTIVE: This study was aimed to determine whether preprocedural ultrasonography (USG) affects the technical performance of spinal anesthesia in elderly patients with difficulty in palpating landmarks, scoliosis, or previous spine surgery. MATERIALS AND METHODS: This prospective study was conducted in 156 elderly patients scheduled for elective orthopedic lower extremity surgery. The patients were randomly divided into 2 groups to receive spinal anesthesia by the preprocedural USG examination (group U) or conventional landmark palpation technique (group P)...

In recent decades, regional plane blocks via ultrasonography have become very popular in regional anesthesia and are more commonly used in pain management. The transversus abdominis plane (TAP) block is a procedure where local anesthetics are applied to block the anterior divisions of the tenth thoracic intercostal through the first lumbar nerves (T10-L1) into the anatomic space formed amidst the internal oblique and transversus abdominis muscles located in the antero-lateral part of the abdomen wall. The most important advantage of this block method is that ultrasonographic identification is easier and its complications are fewer compared with central neuroaxial or paravertebral blocks...

Plane blocks have become very popular in recent years with the introduction of ultrasonography into the regional anesthesia and algology practice. Erector spinae plane (ESP) block involves injection of local anesthetics between erector spinae muscles and transverse process of vertebrae and can block the dorsal and ventral rami of thoracolumbar spinal nerves. The primary factor in the great popularity of this block is easy sonographic identification of landmarks and lower complication rate compared to paravertebral or central neuroaxial blocks...

BACKGROUND: Children that have had a meningomyelocele repair often present for hip and bilateral lower limb surgeries. Due to vertebral, epidural, and nerve root abnormalities, placement of epidural catheter is difficult. AIMS: We aim to describe the potential role of ultrasound in delineating the most appropriate intervertebral space for central neuroaxial blocks in these patients. METHODS: Twelve children with previous meningomyelocele repair, in the age group of 6-12 years posted for hip or bilateral lower limb surgeries were included...

Henceforth, ultrasonography (US) is an indispensible imaging technique in regional anesthesia practice. With the guidance of US, various invasive interventions in chronic pain pathologies of the musculoskeletal system, peripheral and neuroaxial pathologies has become possible. The management includes diagnostic blocks as weel as radiofrequency ablation and institution of neurolythic agents. During these algologic interventions we are able to see the target tissue, the dispersion of the drug and all nearby vascular structures...

OBJECTIVES: Introduction of ultrasound into regional anesthesia (RA) practice has resulted in important changes and developments in RA. These developments have had a major influence on the way of practice and choice of blocks. The purpose of this study was to present the most recent instruments used in RA and clinical applications in our country. METHODS: A questionnaire consisting of 10 questions were distributed to the participants of the National RA Congress in 2011...

INTRODUCTION: Several nerve blocks have recently been used for pain treatment in breast surgery. The main objective of our study was to determine the efficacy and safety of ultrasound-assisted blocking of the anterior and lateral cutaneous branches of the intercostal nerves in the mid-axillary line for non-reconstructive breast and axilla surgery. MATERIAL AND METHODS: A prospective observational study was conducted on 30 patients scheduled for non-reconstructive breast and axilla surgery...

OBJECTIVES: This is a case report and description of a new ultrasound-guided caudad epidural needle placement for percutaneous stimulation of the lumbosacral roots. MATERIALS AND METHODS: Case report. RESULTS: Using ultrasonography pertinent spinal and neuroaxial anatomy was visualized. In-plane approach with continuous monitoring of the needle advancement was utilized. The needle was seamlessly placed in the epidural space on the first attempt...

BACKGROUND AND OBJECTIVES: Caudal epidural anesthesia is the most popular regional anesthesia technique used in children. With advanced age, only the relative difficulty in localizing the sacral hiatus limits its use. However, in adults this technique has been widely used to control chronic pain by adjuvant use of fluoroscopy. Thus, the ability to locate the hiatus and define anatomical variations is the main determinant of the success and safety of caudal epidural anesthesia. In this context, the use of the ultrasound in caudal epidural anesthesia has been increasing...

PURPOSE OF REVIEW: Since Kapral in 1994 first described the use of real-time ultrasound-guided regional anaesthesia, this novel technique has gained widespread recognition in adult practice and has been shown to be associated with clinically relevant advantages. The aim of this manuscript is to review the currently published paediatric data associated with the use of ultrasound-guided regional anaesthesia. RECENT FINDINGS: Compared with alternative techniques ultrasound guidance is associated with an increased success rate, reduced onset time, moderately prolonged duration, reduced need for local anaesthetics and lower costs, and may also be considered to reduce the risk for complications...

Recently, ultrasonography has been increasingly used in the field of regional anesthesia to assure reliable blockade of peripheral nerves and to visualize neuroaxial structures. As its popularity is steadily increasing, it may become a standard of care for both intraoperative analgesia and postoperative pain control. The application of ultrasound in chronic pain management, however, remains underutilized. Multiple reasons can be suggested to explain this situation. Nonetheless, numerous articles have been published and some interventionalists have gained experience and started to spread their knowledge through hands-on workshops and medical meetings...

Ultrasound imaging techniques in regional anaesthesia are becoming a subject of major interest. The quality of blocks and analgesia is relevant to the perioperative outcome of patients and the development of perfect blocks has always been a focus in regional anaesthesia research. Several studies in neuroaxial anaesthesia and peripheral blocks have found that puncture processing performed under ultrasound guidance is easier and more effective than that performed without such guidance, thus ultrasound imaging techniques are being developed for clinical practice...

The technology and clinical understanding of anatomical sonography has evolved greatly over the past decade. In the Department of Anaesthesia and Intensive Care Medicine at the Medical University of Vienna, ultrasonography has become a routine technique for regional anaesthetic nerve block. Recent studies have shown that direct visualization of the distribution of local anaesthetics with high-frequency probes can improve the quality and avoid the complications of upper/lower extremity nerve blocks and neuroaxial techniques...

The use of ultrasound as a diagnostic tool for the visualisation of the epidural space has effects on the quality and the performance of epidural anesthesia. This work presents an overview of the recent experiences with ultrasound for epidural anesthesia and on the possibilities for ultrasound imaging techniques. The results of visualisation of the epidural space and its limiting structures obtained by various working groups are presented. We review all presently available data on the prediction of the puncture depth...
