BACKGROUND: Epidural analgesia is a central nerve block technique achieved by injection of a local anaesthetic close to the nerves that transmit pain, and is widely used as a form of pain relief in labour. However, there are concerns about unintended adverse effects on the mother and infant. This is an update of an existing Cochrane Review (Epidural versus non-epidural or no analgesia in labour), last published in 2011. OBJECTIVES: To assess the effectiveness and safety of all types of epidural analgesia, including combined-spinal-epidural (CSE) on the mother and the baby, when compared with non-epidural or no pain relief during labour...

Surgery is the first-line treatment for early, localized, or operable breast cancer. Regional anesthesia during mastectomy may offer the prevention of postoperative pain. One potential protocol is the combination of serratus anterior plane block (SAM block) with pectoral nerve block I (PECS I), but the results and potential benefits are limited. Our study compared general anesthesia with or without SAM block + PECS I during radical mastectomy with axillary node dissection and breast reconstruction using evaluations of pain, opioid consumption, side effects and serum levels of interleukin (IL)-1beta, IL-6 and IL-10...

INTRODUCTION: Pectoral Nerves Block (PECS) and Serratus Plane Block (SPB) have been used to treat persistent post-surgical pain after breast and thoracic surgery, however they cannot block the internal mammary region, so a residual pain may occur in that region. Parasternal block (PSB) and Thoracic Transversus Plane Block (TTP) anesthetize the anterior branches of T2-6 intercostal nerves thus they can provide analgesia to the internal mammary region. METHODS: We describe a 60-year-old man suffering from right post thoracotomy pain syndrome with residual pain located in the internal mammary region after a successful treatment with PECS and SPB We performed a PSB and TTP and hydrodissection of fascial planes with triamcinolone and Ropivacaine...

INTRODUCTION: There is no standardized approach to the greater occipital nerve (GON) block technique for treating occipital neuralgia. The aim of the present study was to validate the previously-suggested guidelines for conventional injection techniques and to provide navigational guidelines for safe GON block. METHODS & MATERIALS: The GON, lesser occipital nerve (LON) and occipital artery (OA) were carefully dissected in the occipital region of embalmed cadavers...

Background: A stellate ganglion block (SGB) causes increased blood flow in the maxillofacial region, exhibiting the potential for regenerative effects in damaged tissue. The focus of this study was to understand the efficacy of SGB for regenerative effects against nerve damage. A rat model of the superior cervical ganglion block (SCGB) was created instead of SGB, and facial blood flow, as well as sympathetic nervous system function, were measured. Methods: A vertical incision was made on the left side of the neck of a Wistar rat, and a 5-mm resection of the superior cervical ganglion was performed at the back of the bifurcation of the internal and external branches of the left common carotid artery...

Peripheral regional anesthesia procedures, such as femoral nerve block, are relatively safe procedures in clinical anesthesia. Nevertheless, it may lead to typical, usually transient and rarely even persistent complications. This article aims to highlight key aspects of complications in peripheral regional anesthesia and, in particular, strategies to reduce risk. Moreover, beside general complications, which might potentially occur in any peripheral nerve blockade ("bleeding/infection/nerve damage"), accidental co-blockades of other nerval structures are discussed using the example of the brachial plexus...

The PECS II nerve block is a relatively new regional anesthetic technique that targets the medial and lateral pectoral nerves, as well as the lateral cutaneous branches of the intercostal nerves. It has been described for surgical cases involving the breast, as an adjunct or alternative to neuraxial or paravertebral techniques. This case report describes the first successful use of the PECS II nerve block placed using ultrasound guidance as the primary anesthetic and postoperative analgesic in a non-breast-related chest wall surgery...

INTRODUCTION: Difficulty in identifying the susprascapular nerve (SSN) limits the success of US-guided regional anesthetic injections. A proximal SSN block could be an effective and reliable approach. The primary objective was to validate the feasibility of the US-guided proximal SSN block. The secondary objective was to quantify the spread of the colored local anesthetic to the phrenic nerve (PN). MATERIALS AND METHODS: Fourteen brachial plexuses from seven cadavers were included...

PURPOSE: To determine whether an infratrochlear nerve block (ITB) can reduce the oculocardiac reflex (OCR) during strabismus surgery on the medial rectus muscle (MR). METHODS: This prospective, randomized single-masked study included 60 patients with intermittent exotropia scheduled for unilateral MR resection/lateral rectus recession under general anesthesia. Patients were randomly allocated to receive a regional nerve block of the infratrochlear nerve (ITB group) prior to surgery or standard treatment without a nerve block (control group)...

Identification of voltage-gated sodium channel NaV1.7 inhibitors for chronic pain therapeutic development is an area of vigorous pursuit. In an effort to identify more potent leads compared to our previously reported GpTx-1 peptide series, electrophysiology screening of fractionated tarantula venom discovered the NaV1.7 inhibitory peptide JzTx-V from the Chinese earth tiger tarantula Chilobrachys jingzhao. The parent peptide displayed nominal selectivity over the skeletal muscle NaV1.4 channel. Attribute-based positional scan analoging identified a key Ile28Glu mutation that improved NaV1...

Erector spinae plane block (ESP) is a recently described regional anesthesia technique that leads to the blockage of both visceral and somatic nerve fibers. While there are anecdotal reports of ESP used in children, none are for laparoscopic procedures. Herein we report a child undergoing laparoscopic cholecystectomy in which ESP was used as part of multimodal anesthesia. Ultrasound-guided ESP block is an easily performed peripheral nerve block that leads to long-lasting postoperative analgesia. It can be successfully used in pediatric laparoscopic procedures such as cholecystectomy and should be kept in mind as an option for multimodal analgesia in children...

The epaxial muscles produce intervertebral rotation in the transverse, vertical and axial axes. These muscles also counteract the movements induced by gravitational and inertial forces and movements produced by antagonistic muscles and the intrinsic muscles of the pelvic limb. Their fascicles are innervated by the dorsal branch of the spinal nerve, which corresponds to the metamere of its cranial insertion in the spinous process. The structure allows the function of the muscles to be predicted: those with long and parallel fibres have a shortening function, whereas the muscles with short and oblique fibres have an antigravity action...

Spectral analysis of ultrasound radiofrequency backscatter has the potential to identify intercostal blood vessels during ultrasound-guided placement of paravertebral nerve blocks and intercostal nerve blocks. Autoregressive models were used for spectral estimation, and bandwidth, autoregressive order and region-of-interest size were evaluated. Eight spectral parameters were calculated and used to create random forests. An autoregressive order of 10, bandwidth of 6 dB and region-of-interest size of 1.0 mm resulted in the minimum out-of-bag error...

There are few data available that describe the current anaesthetic management of children. We have analysed anaesthetic practice and peri-operative complications for children in Denmark aged less than two years. We conducted a population-based observational cohort study using the Danish Anaesthesia Database to identify children who received anaesthesia in hospital from 1 January 2005 until 31 December 2015. Data were combined with that from the Danish National Patient Registry and the Danish Civil Registration System...

BACKGROUND AND OBJECTIVES: General anesthesia for breast surgery may be supplemented by using a regional anesthetic technique. We evaluated the efficacy of the first pectoral nerve block (Pecs I) in treating postoperative pain after breast cancer surgery. METHODS: A randomized, double-blind, dual-centered, placebo-controlled trial was performed. One hundred twenty-eight patients scheduled for unilateral breast cancer surgery were recruited. A multimodal analgesic regimen and surgeon-administered local anesthetic infiltration were used for all patients...

BACKGROUND AND OBJECTIVES: Major ankle surgery causes intense postoperative pain, and whereas the importance of a sciatic nerve block is well established, the clinical significance of a supplemental saphenous nerve block has never been determined in a prospective, randomized, double-blind, placebo-controlled trial. We hypothesized that a saphenous nerve block reduces the proportion of patients experiencing significant clinical pain after major ankle surgery. METHODS: Eighteen patients were enrolled and received a popliteal sciatic nerve block...

BACKGROUND: Anatomical knowledge dictates that regional anaesthesia after total hip arthroplasty requires blockade of the hip articular branches of the femoral and obturator nerves. A direct femoral nerve block increases the risk of fall and impedes mobilisation. We propose a selective nerve block of the hip articular branches of the femoral nerve by an ultrasound-guided injection in the plane between the iliopsoas muscle and the iliofemoral ligament (the iliopsoas plane). The aim of this study was to assess whether dye injected in the iliopsoas plane spreads to all hip articular branches of the femoral nerve...

Ultrasound (US)-guided transversalis fascia plane block (TFPB) was first described by Hebbard as a technique for blockade of T12-L1 nerves. Although this technique appears similar to the quadratus lumborum 1 block, the point of injection is more caudal and anterior, specifically targeting ilioinguinal and iliohypogastric nerves. There are only few published data on US-guided TFPB demonstrating effective postoperative analgesia in iliac crest bone graft harvesting. We report the use of US-guided TFPB in a patient undergoing inguinal herniorrhaphy...

Isolated fractures of shaft of ulna are common. Plate fixation with anatomic reduction is thought to produce the best functional results in closed or open fractures. Surgery can be done under general and various types of regional anaesthesia. We report a case of fracture shaft of ulna treated by plating under a combination of WALANT (wide awake, local anaesthesia, no tourniquet) using tumescent anaesthesia and periosteal nerve block as a day care procedure.
