quadratus lumborum block

BACKGROUND: Radical surgery is a common treatment for patients with gastric cancer; however, it can lead to postoperative complications and intestinal barrier dysfunction. Ultrasound-guided quadratus lumborum block is often used for postoperative analgesia, but its effects on stress response and intestinal barrier function are not well understood. AIM: To investigate the effects of an ultrasound-guided quadratus lumborum block on stress response and intestinal barrier function in patients undergoing radical surgery for gastric cancer...

The quadratus lumborum block is a technique that is not widely applied in abdominal surgery. The influence of the mode of anesthesia on the outcome of polymorbid patients is a controversial issue in the medical literature. We report a case in which we performed a quadratus lumborum block type 2 on a woman who was admitted to Riga's 1st hospital in need of gastrostomy, due to difficulty swallowing solid foods and liquids caused by hypopharynx carcinoma. On account of the patient's difficult airway, general anesthesia was deemed unsafe for the patient, with a risk of patient death...

ESP block (ESPB) and posterior Quadratus Lumborum Block (pQLB) have been proposed as opioid-sparing techniques for the management of pain after abdominal surgery. Between December 2021 and October 2022, we conducted a retrospective comparative study at the delivery suite of Fondazione Policlinico Universitario Agostino Gemelli IRCCS, Rome, Italy, to compare the efficacy of ESPB and pQLB in preventing postoperative pain after an elective caesarean section (CS). The primary outcome was total morphine consumption in the first 24 h...

The quadratus lumborum (QL) block is an ultrasound-guided locoregional anesthesia technique which aims to provide analgesia to the abdomen. The main objective of this study was to assess a modified ultrasound-guided dorsal QL block in cat cadavers. For this purpose, a volume of 0.4 mL kg-1 of a mixture of iopromide and methylene blue was administered between the psoas minor muscle and the vertebral body (VB) of the first lumbar vertebra, and its distribution was assessed in thirteen cat cadavers. We hypothesized that this injection point would be feasible, offering a more cranial distribution of the injectate and a more consistent staining of the truncus sympathicus...

STUDY OBJECTIVE: This study aimed to determine the effect of the implementation of the Enhanced Recovery After Surgery (ERAS) protocol among patients receiving minimally invasive gynecologic surgery. DESIGN AND SETTING: This retrospective cohort study was performed in a tertiary care hospital. PATIENTS: A total of 328 females who underwent minimally invasive gynecologic surgeries requiring at least one overnight stay at Keck Hospital of University of Southern California (USC), California, USA, from 2016 to 2020 were included in this study...

BACKGROUND: : This study assessed the postoperative analgesic efficacy and safety of the quadratus lumborum block (QLB) in pediatric patients. METHODS: : Electronic databases were searched for studies comparing the QLB to conventional analgesic techniques in pediatric patients. The primary outcome was the need for rescue analgesia 12 and 24 hours after surgery. Secondary outcomes covered the Face-Legs-Activity-Cry-Consolability Scale (FLACC) scores at various time points; parental satisfaction; time to the first rescue analgesia; hospitalization time; block execution time; block failure rates, and adverse events...

BACKGROUND: We aimed to compare the analgesic effect and quality of recovery of transmuscular quadratus lumborum block (QLB) and erector spinae plane block (ESPB) in the presence of multimodal analgesia following Caesarean section. METHODS: This randomised controlled trial included full-term pregnant women who underwent elective Caesarean section under spinal anaesthesia without intrathecal morphine. The included women were randomised to receive either bilateral QLB ( n = 51) or bilateral thoracic ESPB ( n = 51), in addition to the control group ( n = 51) who did not receive any block...

OBJECTIVE: Total laparoscopic hysterectomy is the preferred technique for hysterectomy in obstetrics and gynecology clinics. However, patients who undergo these procedures often experience acute pain that may progress to chronic pain over time. Erector spinae plane block (ESPB) and anterior quadratus lumborum block (QLB) under ultrasound guidance are reported to be effective as part of the multi-modal analgesia protocol. Therefore, this study aimed to compare the effectiveness of erector spinae plane block and anterior quadratus lumborum block in reducing postoperative opioid consumption and pain scores in patients undergoing total laparoscopic hysterectomy...

BACKGROUND: Peripheral nerve block, including the quadratus lumborum block (QLB), has been used for postoperative analgesia in hip surgery. However, the effects of QLB on cognitive function after hip surgery remain unknown. This study aimed to assess the effects of the anterior approach to QLB on postoperative cognitive function in older people undergoing hip surgery. METHODS: Sixty older people who underwent hip surgery from May 2021 to May 2022 were randomly divided into the QLB (n = 30) and control groups (n = 30)...

INTRODUCTION: The management of postoperative pain following lumbar disc herniation (LDH) surgery is crucial for the quality of recovery. The effectiveness of multimodal analgesia plans increases when interfascial plane blocks are included. This study sought to compare the analgesic efficacy of preoperative ultrasound-guided TLIP (thoracolumbar interfascial plane) blocks and posterior QLBs (quadratus lumborum blocks) in patients undergoing LDH surgery. METHODS: Patients undergoing elective LDH surgery under general anesthesia were randomized into two groups: thoracolumbar interfascial plane block (Group T) and posterior quadratus lumborum block (Group Q)...

The aim of this study was to evaluate the effect of the transverse quadratus lumborum block (QLBLQL-T ) on time to the first postoperative rescue analgesia in dogs submitted to laparoscopic ovariectomy. A total of twenty-three female dogs were included. Dogs were randomly assigned to receive a bilateral QLBLQL-T , performed either with 0.3 mL kg-1 ropivacaine 0.5% [group QLB0.5% ( n = 8)] or with ropivacaine 0.33% [group QLB0.33% ( n = 8)] or a fentanyl-based protocol [group No-QLB ( n = 7)]. Dogs were premedicated intravenously (IV) with fentanyl 5 mcg kg-1 , general anesthesia was induced IV with propofol and maintained with sevoflurane...

INTRODUCTION: With the current surge on peripheral nerve blocks in post-cesarean pain management and the historical lack of unequivocal evidence supporting its universal use, this review intended to re-examine the extended scope of literature on regional anesthesia and postoperative analgesia in low-transverse cesarean section. METHODS: A literature search was conducted up to April 2023 using PubMed to identify articles relevant to our search words "cesarean section", "neuraxial morphine", "post-cesarean analgesia", as well as the name of each individual nerve block...

BACKGROUND: The combination of different anesthesia techniques or adjuvant drugs can relieve the stress response to surgery, reduce adverse reactions and improve the clinical outcome. We investigated the effects of subcostal anterior quadratus lumborum block (SQLB) with and without dexmedetomidine (DEX) on postoperative rehabilitation for laparoscopic renal surgery (LRS). METHODS: We included 90 patients in this single-center study. All were scheduled for elective laparoscopic radical or partial nephrectomy under general anesthesia (GA)...

Bone marrow harvesting is a means to obtain stem cells to treat certain hematologic conditions in related or unrelated individuals. The most cited complication after bone marrow harvesting is surgical site pain. We developed a protocol incorporating regional anesthesia to improve pain control and reduce opioid use. A retrospective chart review was performed on three pediatric patients who underwent bone marrow harvesting for a sibling recipient and were managed via a standardized regional pain protocol...

BACKGROUND: Previous studies have investigated the effectiveness and safety of ultrasound-guided fascia iliaca compartment block (UGFICB) compared to quadratus lumborum block (QLB) for pain management in total hip arthroplasty (THA). However, there is currently a lack of a systematic review specifically addressing this issue. Therefore, the purpose of this study was to conduct a comprehensive analysis and comparison of the efficacy and safety of UGFICB versus QLB for pain management in THA...

Effective postoperative analgesia using multimodal approach improves maternal and neonatal outcomes after cesarean delivery. The use of neuraxial approach (local anesthetic and opioids) and intravenous adjunctive drugs, such as nonsteroidal anti-inflammatory drugs and acetaminophen, currently represents the standard regimen for post-cesarean delivery analgesia. Peripheral nerve blocks may be considered in patients who are unable to receive neuraxial techniques; these blocks may also be used as a rescue technique in selected patients...

OBJECTIVE: To develop an ultrasound-guided caudal quadratus lumborum block (C-QLB) technique in canine cadavers and to compare sensory and motor blockade resulting from the combination of ultrasound-guided greater ischiatic notch (GIN) plane and C-QLB approaches (GIN-CQLB group) versus a lumbosacral plexus (LSP group) approach [combination of lateral pre-iliac (LPI) and parasacral (PS) techniques] in dogs. STUDY DESIGN: Descriptive anatomical study and prospective randomized, blinded, experimental crossover trial...

Regional pain management after hip arthroscopy is challenging. The hip capsule alone has a complex and highly variable innervation, including contributions from articular branches of the femoral, obturator, accessory obturator, accessory femoral, superior gluteal, accessory superior gluteal, inferior gluteal, sciatic, and posterior femoral cutaneous nerves, nerve to the quadratus femoris, as well as a direct supply from the lumbosacral plexus. Thus, it is unrealistic to expect a traditional peripheral nerve block, including blocks of the proximal lumbar plexus, femoral nerve, and fascia iliaca region to provide thorough hip analgesia without inducing quadriceps weakness that could result in a patient experiencing a fall during the postoperative period...

OBJECTIVE: This prospective randomized study was conducted at Ataturk University Medical Faculty Hospital, Department of Anesthesia and Reanimation, from June 2022 to May 2023. The aim of this study was to compare the effectiveness of ultrasound-guided erector spinae plane block, quadratus lumborum block, and intrathecal morphine to decrease postoperative pain after cesarean section. METHODS: Sixty-term pregnant women who were scheduled for elective cesarean sections with spinal anesthesia were included...

We investigated the efficacy and safety of a bilateral anterior quadratus lumborum block in patients undergoing minimally invasive colorectal surgery. This was a two-centre, double-blind, prospective, randomised, placebo-controlled trial including 150 patients undergoing laparoscopic colorectal surgery (left- or right hemicolectomy, sigmoidectomy) who were enrolled in the institutional abdominal enhanced recovery programme. Before induction of anaesthesia, patients received a bilateral anterior quadratus lumborum block in the left and right lateral decubitus position under ultrasound guidance and were allocated randomly to receive 30 ml of ropivacaine 0...
