INTRODUCTION: The aim of the current study was to compare block of the sciatic nerve through the anterior approach by two methods, namely, the nerve-stimulator guided and ultrasound-guided, with or without nerve stimulation, with regard to the ease of performance, reliability and safety of this approach. PATIENTS AND METHODS: 36 adult patients were randomly allocated equally into one of 2 main groups: "Nerve Stimulator-Guided Group (NSG)" where the nerve was located by nerve stimulator only and "Ultrasound guided group (USG)" where the sciatic nerves were blocked by a stimulated needle under guidance of the ultrasound...

BACKGROUND: Optimum positioning of the nerve catheter is crucial for a successful nerve block. We present a novel technique for confirmation of catheter position. METHODS: We are describing a novel technique for localization of the shaft and tip of the peripheral nerve catheter. After introduction of the catheter 3 to 5 cm beyond the needle tip and removal of the needle, the guide wire was reintroduced and was moved inward and outward rapidly. This movement produced the color Doppler effect along the track of the catheter and the catheter tip that helped us verify the proper positioning of the catheter...

BACKGROUND: Obturator nerve block plays an additive role on the quality of analgesia for knee surgery. Since the use of dual guidance increases the success rate of nerve blocks, we investigated the feasibility of performing anterior cruciate ligament reconstruction under dual-guided blockade of obturator with femoral and sciatic nerves. Furthermore, we propose a novel method for the assessment of obturator nerve block. METHODS: Fifty-seven patients undergoing anterior cruciate ligament repair were studied...

BACKGROUND: The prevalence of anterior knee pain following intramedullary tibial nail insertion is high. Continuous peripheral nerve blockade is an alternative method of pain control to opiods. This case illustrates the use of femoral nerve and sciatic nerve peripheral catheters with an elastomeric infusion pump for major intramedullary nailing surgery. CASE REPORT: A 36-year-old male with fractures to the left leg bones presented for placement of an intramedullary nail under spinal anesthesia...

AIMS: No pharmacokinetic data exist on doses of ropivacaine larger than 300 mg for peripheral nerve block in man, although in clinical practice higher doses are frequently used. The purpose of the present study was to describe the pharmacokinetic profile in serum of 450 mg ropivacaine with and without epinephrine in patients undergoing anterior cruciate ligament reconstruction. METHODS: Twelve patients were randomly allocated to receive a single shot combined sciatic/femoral nerve block with 60 ml of either ropivacaine 0...

Ultrasound guidance has made it possible to carry out an anterior approach to sciatic nerve block. This technique can be performed as fast and as successfully as the posterior or subgluteal approach. A major advantage of this technique is that the patient can remain comfortable in a neutral supine position.

BACKGROUND AND OBJECTIVES: A major concern with the use of continuous peripheral nerve block is the difficulty encountered in placing the catheters close enough to the nerves to accomplish effective analgesia. The aim of this study was to investigate if a self-coiling catheter would remain close to the sciatic nerve once introduced through needles placed under ultrasound guidance and if contrast dye injected through the pigtail catheter made direct contact to the nerves. METHODS: First, Tuohy needles were placed anterior to the sciatic nerves under ultrasound guidance (needle-in-plane/nerve in short-axis approach)...

BACKGROUND: Sciatic nerve block is a commonly used technique for providing anesthesia and analgesia to the lower extremity. At the parasacral level, the nerve block is classically performed via a posterior approach in lateral decubitus position causing patient's discomfort. Therefore, we aimed to conduct an anatomical study describing a new lateral approach to the parasacral sciatic nerve in supine position. METHODS: The skin entry point was located on the vertical line through the greater trochanter (GT) at the midpoint between the anterior superior iliac spine (ASIS) level and the GT...

Obturator nerve block is commonly used for transurethral resections of the bladder in order to inhibit reflectory adductor muscle reaction during electrocoagulation and to reduce the risk of bladder wall perforation during transurethral surgery. Furthermore, obturator block is used to complete regional blocks for major knee surgery in addition to femoral and sciatic nerve blocks. Continuous techniques are sometimes used to treat chronic pain problems such as adductor spasm. During a so called "3 in 1" block (femoral nerve block) the obturator nerve will only be anaesthetized in 0-62% of the patients...

BACKGROUND: Sciatic nerve block is a commonly used technique for providing anesthesia and analgesia to the lower extremity. It is classically performed through posterior or lateral approaches. However, an anterior approach should be considered in certain conditions where patient positioning would be complicated. The success rate of the sciatic nerve block with previously defined approaches has been reported to be low, however, the complication rate with such approaches has been found to be high...

INTRODUCTION: The usual technique of parasacral sciatic nerve block seems an approach easily achieved, however, the ischial tuberosity is difficult to palpate. [1] The purpose of the study was to propose new skin landmarks improved by an anatomical and clinical study. PATIENTS AND METHODS: Three cadaver dissections made previously have shown that our skin landmarks appeared correct. Twenty consenting patients, ASA I to III, proposed for lower limb surgery, were included in this descriptive and prospective study...

BACKGROUND AND OBJECTIVES: The sciatic nerve may be blocked by several routes, all of them with advantages and disadvantages. It is the largest human nerve in diameter and length, being the prolongation of the upper sacral plexus fascicle (L4, L5, S2 and S3). It leaves the pelvis through the foramen ischiadicum majus, passing below the piriform muscle and going down between the greater trochanter and the ischial tuberosity, continuing along the femoral dorsum, anterior to biceps femoris and semitendinous muscles, to the lower femoral third, where it is divided in two major branches called tibial and common fibular nerves...

BACKGROUND: Although the anterior approach to the sciatic nerve block has rarely been performed due to lack of reliable surface anatomical landmarks and technical difficulty, ultrasound guidance may make performance of this approach easier. In this study, we evaluated the clinical use of the ultrasound-guided anterior approach to sciatic nerve block and compared this approach with the posterior approach in adults. METHODS: One hundred patients undergoing minor knee surgery were randomly divided into two groups to receive anterior and posterior (subgluteal) approaches to sciatic nerve block, using 1...

REVIEW
Junichi Ota, Kaoru Hara
Theoretically, sciatic nerve block can be used alone or in combination with lumbar plexus block or femoral nerve block for anesthesia and/or analgesia of lower limb surgery. However, clinical use of sciatic nerve block was limited by technical difficulties in performing the block since techniques used relies only on surface anatomical landmarks. Recent advances in ultrasound technology allow direct visualization of nerves and other surrounding structures and have increased the interest in performing many kinds of peripheral nerve blocks including sciatic nerve block...

BACKGROUND: The ability of parasacral sciatic nerve block to provide consistent obturator nerve and perineal blockade remains undetermined. In this anatomic work, we assessed the spread of a colored latex mimicking a parasacral injection, and observed the spread to the obturator nerve and sacral nerve roots. METHODS: Fourteen parasacral injections were performed bilaterally on seven human cadavers. Dissection was performed in two steps. First, the posterior approach confirmed the presence of dye on the sciatic nerve at the level of the piriformis muscle to define the success of the injection...
