A fully-automatic ultrasound image processing system that can determine the needle entry site for epidural anesthesia (EA) in real time is presented in this paper. Neither the knowledge of anesthetists nor additional hardware is required to operate the system, which firstly directs the anesthetists to reach the desired insertion region in the longitudinal view, i.e., lumbar level L3-L4, and then locates the ideal puncture site by instructing the anesthetists to rotate and slightly adjust the position of ultrasound probe...

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...

BACKGROUND: The transversus abdominis plane (TAP) block is a regional anesthesia technique that effectively reduces the pain intensity and use of analgesia in abdominal surgery. The aim of this study was to determine the utility of the ultrasound-guided TAP block in improving the efficacy of the ultrasound-guided ilioinguinal/iliohypogastric nerve (IIN/IHN) block for intraoperative anesthesia and postoperative pain control in day-case inguinal hernia repair (IHR). METHODS: We conducted a descriptive study of patients undergoing elective primary unilateral open IHR...

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...

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...

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...

BACKGROUND: Digital ischemia is associated with several rheumatologic disorders and is often difficult to treat. Symptoms and sequelae can include pain, disability, need for amputation, and poor quality of life. METHODS: Patients diagnosed with digital ischemia were referred for an ultrasound-guided axillary nerve block using liposomal bupivacaine (Exparel, Pacira Pharmaceuticals). The primary outcome measure was radial and ulnar artery diameter preprocedure and postprocedure...

Background. Distal arm surgery is widely performed under regional anesthesia with brachial plexus block. The preponderance of evidence for the efficacy relies upon injection of local anesthetic in excess of 30 mL. We aimed to compare three different ultrasound-guided brachial plexus block techniques restricting the total volume to 20 mL. Methods. 120 patients were prospectively randomized to ultrasound-guided brachial plexus block with 20 mL ropivacaine 0.75% at either the supraclavicular, infraclavicular, or axillary level...

BACKGROUND: Lower extremity trauma during earthquakes accounts for the largest burden of disaster-related injuries. Insufficient pain management is common in resource-limited disaster settings, and regional anesthesia (RA) may reduce pain in injured patients beyond current standards of care. To date, no controlled trials have been conducted to evaluate the use of RA for pain management in a disaster setting. METHODS/DESIGN: The Regional Anesthesia for Painful Injuries after Disasters (RAPID) study aims to evaluate whether regional anesthesia (RA), either with or without ultrasound (US) guidance, can reduce pain from earthquake-related lower limb injuries in a disaster setting...

Used in clinical practice as part of a multimodal analgesic regimen, the transversus abdominis plane block (TAP block) is a relative novel procedure in which local anaesthetic agents are injected into the anatomic neurofascial space between the internal oblique and the transversus abdominis muscle. It allows a significantly prolonged duration of analgesia during the early postoperative stage in abdominal surgery. This regional anesthesia technique provides analgesia to the skin, muscles of the anterior abdominal wall and parietal peritoneum in order to decrease the incision-related pain...

Ultrasound-guided regional anesthesia can be challenging, especially for inexperienced physicians. The goal of the proposed methods is to create a system that can assist a user in performing ultrasound-guided femoral nerve blocks. The system indicates in which direction the user should move the ultrasound probe to investigate the region of interest and to reach the target site for needle insertion. Additionally, the system provides automatic real-time segmentation of the femoral artery, the femoral nerve and the two layers fascia lata and fascia iliaca...

BACKGROUND: Ultrasound-guided techniques improve outcomes in regional anesthesia when compared with traditional techniques; however, this assertion has not been studied with novices. The primary objective of this study was to compare sensory and motor block after axillary brachial plexus block when performed by novice trainees allocated to an ultrasound- or nerve-stimulator-guided group. A secondary objective was to compare the rates of skill acquisition between the 2 groups. METHODS: This study was a prospective, randomized, observer-blinded, 2-arm controlled trial...
