Background: Serratus plane block is a thoracic truncal block that has been proposed as alternatives for analgesia such as epidural anesthesia and paravertebral block for the anterolateral chest wall. Previously, we performed the clinical study about optimal volume of the local anesthetic in serratus plane block. The primary aim of this study was to assess the pattern of distribution of dye into the serratus plane of cadavers after ultrasound-guided serratus plane injection. Findings: Ultrasound-guided serratus plane injection was performed at the level of the fourth rib on the mid-axillary line in nine adult Thiel-embalmed cadavers...

Ultrasound-guided interscalene brachial plexus blockade (IBPB) has a relatively high success rate in shoulder surgery; however, whether multiple injections are superior to a single injection (SI) is currently unknown. In the present study, ultrasound-guided SI and triple-injection (TI) IBPBs were compared in a prospective randomized trial. A total of 111 patients undergoing arthroscopic shoulder surgery and presenting with an American Society of Anesthesiologists physical status grading of I-II were randomly allocated to receive IBPB with 15 ml of 1% ropivacaine as a SI or TI...

INTRODUCTION: Acute ipsilateral shoulder pain (ISP) is a common complaint in patients after thoracotomy. The incidence ranges from 21% to 97%. Unfortunately, clinical studies did not put enough focus on ISP post thoracic surgery. AIM OF THE WORK: This study was designed to compare the effectiveness of suprascapular nerve block (SNB) and phrenic nerve infiltration (PNI) for controlling ISP. PATIENTS AND METHODS: One hundred and thirty-five lung cancer patients (135) scheduled for open-lung surgery were randomly allocated into three equal groups; control group: received thoracic epidural with general anesthesia, suprascapular group: (SNB) one hour before the operation with 10 ml bupivacaine plus thoracic epidural with general anesthesia and phrenic nerve group: (PNI) was performed by the operating surgeon with 10 ml bupivacaine plus thoracic epidural with general anesthesia...

BACKGROUND: Nerve block is usually performed before surgery because it inhibits reflection of the skin incision and reduces the amount of intraoperative anesthetic used. We hypothesized that performing rectus sheath block (RSB) after surgery would result in a longer duration of the analgesic effects and have a subtle influence on sleep time after surgery but that it would not decrease the perioperative cytokine levels of patients undergoing gynecological surgery. METHODS: A randomized, double-blinded, controlled trial was conducted from October 2015 to June 2016...

Background: Transrectal ultrasound-guided prostate biopsy (TRUSPB) is considered the procedure of choice for the diagnosis of prostate cancer. Men undergoing this biopsy experience high psychological stress. Different studies recommend techniques as sedation, lidocaine gel intrarectally, periprostatic nerve block alone, or nitrous oxide inhalation as effective methods of analgesia during procedural-related pain or discomfort. We evaluated three techniques for pain relief during TRUSPB and evaluated if there was any increase in the incidence of complications when employing either technique...

BACKGROUND: Although the safety and effectiveness of the short-axis in-plane method has been confirmed for lumbar plexus block, the operation is difficult and has a high rate of epidural spread at the plane of the articular process. Therefore, we developed a new in-plane technique, called the beach chair method, which displays images from the transverse process. We compared the operative difficulty and incidence of epidural spread of the beach chair method with those of the control method (at the plane of the articular process) in this randomized controlled clinical trial...

BACKGROUND AND OBJECTIVES: Nerve blockade of the lateral femoral cutaneous (LFC) nerve provides some analgesia after hip surgery. However, knowledge is lacking about the extent of the cutaneous area anesthetized by established LFC nerve block techniques, as well as the success rate of anesthetic coverage of various surgical incisions. Nerve block techniques that rely on ultrasonographic identification of the LFC nerve distal to the inguinal ligament can be technically challenging. Furthermore, the branching of the LFC nerve is variable, and it is unknown if proximal LFC nerve branches are anesthetized using the current techniques...

REVIEW
Dajie Wang
Chronic pain is a common medical condition. Patients who suffer uncontrolled chronic pain may require interventions including spinal injections and various nerve blocks. Interventional procedures have evolved and improved over time since epidural injection was first introduced for low back pain and sciatica in 1901. One of the major contributors in the improvement of these interventions is the advancement of imaging guidance technologies. The utilization of image guidance has dramatically improved the accuracy and safety of these interventions...

BACKGROUND: Recently, several studies suggested that radiofrequency (RF) ablation of the genicular nerves is a safe and effective therapeutic procedure for intractable pain associated with chronic knee osteoarthritis (OA). Diagnostic genicular nerve block (GNB) with local anesthetic has been generally conducted before making decisions regarding RF ablation. Although GNB has been recently performed together with corticosteroid, the analgesic effects of corticosteroids for treating chronic pain remain controversial...

BACKGROUND: Understanding the characteristics of the middle cervical sympathetic ganglion (MCSG) may minimize procedure-related complications and maximize efficacy during surgery or ultrasound (US)-guided procedures. The location and detection rate of the MCSG were variable in small population studies. Therefore, a large population study or meta-analysis could give more information about the MCSG. OBJECTIVES: We aim to review the published literature and evaluate the anatomical features of the MCSG, including the detection rate, location, size, and a normal variation, and to review the clinical relevance of MCSG for procedures including, US-guided ganglion block, ethanol ablation (EA), or radiofrequency ablation (RFA)...

The recent development of ultrasound-guide nerve block has led to innovation in anesthesia and pain clinics. However, it has also led to some complex issues, including (1) how to name a new technique, (2) the appropriateness of an intramuscular approach, and (3) how to publicize a new technique. This review addresses naming strategy, feasibility of intramuscular approach block, and methods of publication. First, researchers and authors should pay attention to appropriate nomenclature for the term 'approach', 'compartment block', and 'nerve block' for a new block...
