Obturator nerve block

PURPOSE: Transurethral resection of bladder tumour (TURBT) is done under general anaesthesia (GA) with muscle relaxation to prevent obturator jerk and bladder perforation. TURBT under spinal anaesthesia (SA) with obturator nerve block (ONB) may prevent the obturator jerk while eliminating the disadvantages of GA. OBJECTIVES: To assess the outcome of TURBT under SA and ONB. METHODS: Patients undergoing TURBT for lateral wall tumours from 01...

OBJECTIVES: To examine the efficacy of regional anesthesia with sedation only for a variety of hip fractures using the newly described lateral femoral cutaneous with over the hip Block (LOH Block). DESIGN: Retrospective. SETTING: Level-I Trauma CenterPatients/Participants: 40 patients who presented between 11/2021 and 02/2022 for fixation of OTA/AO 31.A1-3 and 31.B1-3 fractures. Matched cohorts of 40 patients who received general anesthesia and 40 patients who received spinal anesthesia for hip fracture fixation were also used...

Iliopsoas plane (IP) is a fascial plane deep to the iliopsoas complex that can serve as a potential space for the injection of local anesthetics to selectively block the articular branches of femoral nerve and accessory obturator nerve to the anterior hip capsule. Two highly similar ultrasound-guided interfascial plane blocks that target the IP, pericapsular nerve group (PENG) block and iliopsoas plane block (IPB), were both designed to achieve motor-sparing sensory block to the anterior hip capsule. However, the most recent evidence shows that PENG block can cause 25% or more of quadriceps weakness, while IPB remains the hip block that can preserve quadriceps strength...

Total Knee Arthroplasty (TKA) is an increasingly common procedure performed for advanced osteoarthritis. Optimal perioperative pain management strategies are critical for early mobilization and shorter hospital stays in TKA. Peripheral nerve blocks commonly used in TKA perioperative analgesia including individual and combined femoral, obturator, sciatic, lumbar plexus, and adductor canal nerve blocks. Overall, the safety profile varies depending on which block is utilized, but the current evidence suggests when optimally chosen and delivered, peripheral nerve blocks may provide a safe, effective option for perioperative analgesia...

Background: Transurethral resection of bladder tumors (TURBT) is the main surgical treatment for bladder cancer, but during TURBT, it is easy to stimulate the obturator nerve passing close to the lateral side of the bladder wall and induce involuntary contraction of the adductor muscle group of the thigh innervated by it, which will affect the surgical process and lead to adverse reactions. Obturator nerve block (ONB) helps to prevent the obturator nerve reflex. This study systematically evaluated and meta-analyzed the reports on the co-application of ONB and spinal anesthesia (SA) in TURBT in recent years to provide evidence for clinical diagnosis and treatment...

BACKGROUND: Many regional anaesthetic techniques have been proposed to manage pain after total knee arthroplasty, but the best approach is unclear. We compared opioid consumption in the first 48 h between two different regional anaesthesia strategies in patients undergoing total knee arthroplasty. METHODS: In this single-centre, prospective study, we randomly allocated 90 patients to a combination of IPACK (interspace between popliteal artery and capsule of the posterior knee), triangle femoral and obturator nerve blocks (distal group), or a combination of sciatic, femoral, obturator, and lateral femoral cutaneous nerve blocks (proximal group)...

Introduction : With an increasingly ageing population, there is a growing impact of fragility hip fracture on the healthcare system and on society as a whole. Oral and injectable analgesics are often insufficient whilst traction and regional blocks do not allow patients to be discharged easily. While the conventional approach of ultrasound-guided anterior hip pericapsular neurolysis can help a lot of inoperable hip fracture patients to relieve their fracture pain and facilitate subsequent nursing care, enormous technical challenges are encountered in some cases...

Background The majority of bladder cancer patients are elderly and have various comorbidities, increasing the risk of complications following general anesthesia. Spinal anesthesia with a selective obturator nerve block (ONB) is an alternative to general anesthesia for transurethral resection of bladder tumor (TURBT); however, incomplete ONB can cause adductor muscle spasm. The objective of this study was to assess if the ultrasound-guided interfascial injection approach is compatible with the blind nerve stimulating technique for ONB in bladder cancers undergoing TURBT...

OBJECTIVE: To determine the effect of blocking the obturator nerve in addition to performing femoral nerve and sciatic nerve blocks on intraoperative nociception in dogs undergoing unilateral tibial plateau levelling osteotomy (TPLO) surgery. STUDY DESIGN: Prospective, blinded, randomized, placebo-controlled, clinical comparison. ANIMALS: A total of 88 client-owned dogs undergoing unilateral TPLO surgery (100 procedures). METHODS: Dogs were randomly assigned to either group FSO (femoral, sciatic and obturator nerve blocks) [n = 50; ropivacaine 0...

Obturator nerve block (ONB) has been widely applied in transurethral resection of bladder tumor and knee surgery to prevent serious complications such as bladder perforation or to improve the quality of anesthesia during knee surgery. The classic/pubic and inguinal ONB methods are the two primary approaches used. The classic and inguinal ONB methods are two techniques for anesthetizing the obturator nerve, and each method may result in different respective outcomes. We aimed to compare the efficacy of the classic and inguinal methods...

BACKGROUND: Peripheral nerve blocks (PNBs) are vital in the administration of surgical analgesia and have grown in popularity for use in lower extremity arthroscopic procedures because of their capacity to safely and effectively control pain. The number and specificity of PNBs, however, have made choosing the best option for a procedure nebulous for orthopaedic surgeons. PURPOSE: To present a narrative literature review of the PNBs available for arthroscopic hip and knee procedures that is adapted to an audience of orthopaedic surgeons...

AIM: During transurethral resection of bladder tumor (TUR-BT), adductor muscle spasms in varying degrees can be seen due to stimulation of obturator nerve if the tumor is in the inferolateral localization. This can cause some serious complications such as bladder perforation. We aim to show the effectiveness of obturator nerve block (ONB) to avoid the adductor muscle spasm in general anesthesia applied with laryngeal mask (LMA) without using muscle relaxant according to the spinal anesthesia method...

PURPOSE: Peripheral nerve blocks can be a suitable alternative to central neuraxial blockage, as the sole anaesthetic agent for better early postoperative outcomes, decreased hospital stay and earlier mobilisation after anterior cruciate ligament reconstruction (ACLR) surgery. The purpose of this study was to compare consciousness during the procedure, pain during early postoperative period (< 7 days), and perioperative outcomes following ACLR using combined sciatic, femoral, and obturator nerve blocks compared to the spinal anaesthesia...

INTRODUCTION: The aim of the study was to evaluate the effectiveness of a modified transvesical obturator nerve block (ONB) in the prevention of obturator nerve reflex and consecutive bladder perforations (BPs) during transurethral resection of bladder tumors (TURBTs). MATERIALS AND METHODS: A retrospective analysis of all patients resected in 2014-2015 due to a bladder tumor of the lateral walls, including a follow-up period until December 2018, was performed. Two groups were defined: in the first group, all patients underwent TURBT with a modified transvesical ONB...

PURPOSE: We aimed to investigate the effects of obturator nerve block (ONB) on obturator reflex, incomplete resection, perforation, progression and recurrence of tumor, presence of muscle tissue in the specimen, need for a second transurethral resection (TURBT) of bladder tumors, and postoperative complications in patients who underwent TURBT for intermediate-high risk lateral wall non-muscle invasive bladder cancers (NMIBC). MATERIAL AND METHODS: Patients were assigned to one of two groups by drawing lots: ONB or none ONB...

BACKGROUND: When an obturator nerve block (ONB) is performed, the conventional landmark method or ultrasound-guided method is used. The major complications of this block are hematoma, but there are very few reports of its complications. We encountered massive bleeding and a huge hematoma after ONB. Case Presentation . A 95-year-old female underwent transurethral resection of the bladder tumor. Induction of anesthesia was accomplished via spinal anesthesia and right ONB using the landmark method...

Nine participants undergoing primary TKA submitted to spinal anesthesia, sedation, ultrasound-guided obturator and Femoral nerve Block analgesia, and photobiomodulation Therapy (FBMT) were evaluated regarding postoperative pain and morphine consumption. FBMT sessions were performed in the Immediate Postoperative period (IPO) and after 24 hours. Participants received 16.7±15 mg of morphine up to the third postoperative day. At IPO, mean pain score was 4.8±3.2 and 5.6±3.5, at rest and on movement, respectively...
