PURPOSE OF REVIEW: Is ultrasound guidance changing the practice of upper extremity regional anesthesia? This review will aim to describe the findings published in the literature during the previous 18 months. RECENT FINDINGS: In some approaches to brachial plexus blockade, local anesthetic volumes may be reduced without deterioration of analgesic effect. However, even 10 ml of local injected into the interscalene space may result in diaphragmatic paresis. High-resolution ultrasonography has revealed anatomical variations of C5, C6 and C7 nerve roots in almost half of the patients examined, without negative block effectiveness...

Regional anesthesia of the upper extremity has several clinical applications and is reported to have several advantages over general anesthesia for orthopaedic surgery. These advantages, such as improved postoperative pain, decreased postoperative opioid administration, and reduced recovery time, have led to widespread acceptance of a variety of regional nerve blocks. Interscalene block is the most commonly used block for shoulder surgery. Other brachial plexus nerve blocks used for orthopaedic surgery of the upper extremity are supraclavicular, infraclavicular, and axillary...

UNLABELLED: Interventional pain management techniques play an important role in the multidisciplinary approach to management of complex regional pain syndrome (CRPS). In this preliminary study we compared the efficacy of continuous stellate ganglion (CSG) block with that of continuous infraclavicular brachial plexus (CIBP) block in management of CRPS type I of upper extremity. METHODS: Thirty-three patients with CRPS type I of upper extremity were randomly assigned to either CSG or CIBP group...

PURPOSE OF REVIEW: Ultrasound-guidance is gaining tremendous popularity. There is growing evidence of value with emphasis on clinical relevance, but can ultrasound-guidance scientifically warrant changing the practice of upper extremity regional? The literature is searched to describe findings where ultrasound may reduce complication rates, reduce block performance times, and improve block efficacy and quality. RECENT FINDINGS: Ultrasound examination identified variations in anatomical positioning of C5-C7 roots in approximately half of all patients despite no deleterious effects on block efficacy...

OBJECTIVE: Subclavian vein catheterization may cause various complications. We compared the real-time ultrasound-guided subclavian vein cannulation vs. the landmark method in critical care patients. DESIGN: Prospective randomized study. SETTING: Medical intensive care unit of a tertiary medical center. PATIENTS: Four hundred sixty-three mechanically ventilated patients enrolled in a randomized controlled ISRCTN-registered trial (ISRCTN-61258470)...

BACKGROUND: Although the efficacy of single-injection supraclavicular nerve blocks is well established, no controlled study of continuous supraclavicular blocks is available, and their relative risks and benefits remain unknown. In contrast, the analgesia provided by continuous infraclavicular nerve blocks has been validated in randomized controlled trials. We therefore compared supraclavicular with infraclavicular perineural local anesthetic infusion following distal upper-extremity surgery...

Background. There are a variety of techniques for targeting placement of an infraclavicular blockade; these include eliciting paresthesias, nerve stimulation, and 2-dimensional (2D) ultrasound (US) guidance. Current 2D US allows direct visualization of a "flat" image of the advancing needle and neurovascular structures but without the ability to extensively analyze multidimensional data and allow for real-time manipulation. Three-dimensional (3D) ultrasonography has gained popularity and usefulness in many clinical specialties such as obstetrics and cardiology...

BACKGROUND AND OBJECTIVES: Stimulating catheters provide feedback regarding the location of the catheter tip in relation to the target nerve or plexus. There is debate concerning whether stimulating catheters may reduce the failure rate of postoperative analgesia or whether they may enhance functional recovery by providing superior and more reliable postoperative analgesia. METHODS: Studies comparing the effect of stimulating versus nonstimulating catheters for postoperative analgesia were systematically and independently searched by 2 authors...

OBJECTIVE: Electrical stimulation (ES)- and ultrasound-guided placement techniques have been described for infraclavicular brachial plexus perineural catheters but to our knowledge have never been previously compared in a randomized fashion, leaving the optimal method undetermined. We tested the hypothesis that infraclavicular catheters placed via ultrasound guidance alone require less time for placement and produce equivalent results compared with catheters placed solely via ES. METHODS: Preoperatively, patients receiving an infraclavicular perineural catheter for distal upper extremity surgery were randomly assigned to either ES with a stimulating catheter or ultrasound guidance with a nonstimulating catheter...

Local anesthetic perineural infusion has emerged as an effective analgesic technique in pediatric patients, but it can also complement surgical perioperative management in complex cases that require optimal tissue perfusion such as limb salvage. We report the successful use of brachial plexus perineural infusion in the care of a child following near-amputation of her dominant hand. An ultrasound-guided infraclavicular brachial plexus catheter was placed in the recovery room after complex reconstructive surgery and a continuous infusion of 0...

Two important issues after a complete right forearm amputation are replantation and ongoing pain management. There are no reports of successful forearm replantation as a consequence of a crocodile bite. Here, we discuss our pain management in a case of complete forearm amputation after a bite from a saltwater crocodile (Crocodylus porosus), which necessitated six further operations to achieve successful replantation. Continuous infraclavicular brachial plexus block was effective for acute pain control in this case...

BACKGROUND: It remains unclear whether local anesthetic concentration or total drug dose is the primary determinant of continuous peripheral nerve block effects. The only previous investigation, involving continuous popliteal-sciatic nerve blocks, specifically addressing this issue reported that insensate limbs were far more common with higher volumes of relatively dilute ropivacaine compared with lower volumes of relatively concentrated ropivacaine. However, it remains unknown if this relationship is specific to the sciatic nerve in the popliteal fossa or whether it varies depending on anatomic location...

BACKGROUND: Secondary catheter failure has been reported in up to 40% of patients with continuous peripheral nerve blocks resulting in failure to provide pain relief after the initial block wears off. Introduction of stimulating catheters as well as ultrasound for regional anaesthesia has facilitated correct placement of catheter tip, closer to the plexus. This randomized study was conducted to compare the efficacy of continuous infraclavicular brachial plexus blocks using non-stimulating catheter, stimulating catheter and ultrasound-guided catheter placement with nerve stimulation assistance...

Ultrasonographic guidance has been introduced as an aid to nerve localization, for brachial plexus blockade in the interscalene and infraclavicular regions. Ultrasound-guided interscalene approach and infraclavicular approach were established as an excellent method to provide good analgesia during surgery and relieve post-surgical pain after shoulder or upper arm surgery and forearm or hand surgery respectively. Single shot injection and continuous catheter approach in both nerve blocks were described together with clinical key points based on the ultrasound images...

OBJECTIVE: The application of continuous peripheral nerve block (CPNB) has been an important anesthetic tool in the management of combat soldiers wounded from current conflicts. Placing and maintaining CPNBs becomes a challenge in this patient population due to concomitant prophylactic and therapeutic anticoagulation. CASE REPORT: A 32-year-old male sustained multiple traumatic injuries from an improvised explosive device, including a right tibial fracture, a left tibial fracture, and a left ulnar fracture...

PURPOSE: We describe our experience of combining the use of ultrasound (US) guidance with contrast enhancement and peripheral nerve stimulation for the insertion of infraclavicular brachial plexus catheters. METHODS: Thirty patients scheduled to have upper limb surgery under regional block were studied. Under US guidance and peripheral nerve stimulation assistance, continuous peripheral nerve block needle and stimulating catheter were placed in the infraclavicular area...

INTRODUCTION: The infraclavicular approach to the brachial plexus provides suitable anesthesia and also lends itself well to stabilizing and securing a catheter for a continuous infusion. We describe an approach for continuous infusions using an infraclavicular approach in children. METHODS: Twenty-five patients aged 8 mo to 3 yr, weighing 7-14 kg, scheduled for forearm and hand surgeries were studied. The infraclavicular brachial plexus was located using a nerve stimulator attached to a sheathed 19-gauge Touhy needle...

Despite the increasing use of ultrasound, electrical nerve stimulation is commonly used as the standard for both plexus and peripheral nerve blocks. Several recent randomized trials have contributed to a better understanding of physiological and clinical correlations. Traditionally used currents and impulse widths are better defined in relation to the distance between needle tip and nerves. Commercially available devices enable transcutaneous nerve stimulation and provide new opportunities for the detection of puncture sites and for training...

BACKGROUND AND OBJECTIVES: This prospective study compared the initial block quality and surgical anesthesia rates of ultrasound-guided infraclavicular blocks with local-anesthetic injected through a catheter versus through a needle. We hypothesized that positioning of the catheter immediately posterior to the axillary artery would produce through-the-catheter (TTC) anesthesia with rates of complete block not inferior to through-the-needle (TTN) injection. METHODS: Eighty patients undergoing hand or forearm surgery extensive enough to require regional anesthesia were randomized into 2 groups of 40...
