quadratus lumborum block

BACKGROUND: Following the gastrectomy, the reduction in pulmonary function is partly attributed to postoperative pain. Subcostal quadratus lumborum block (QLB) has recently emerged as a promising component in multimodal analgesia. We aimed to assess the impact of intermittent boluses of subcostal QLB on pulmonary function recovery and analgesic efficacy after gastrectomy. METHODS: Sixty patients scheduled for gastrectomy were randomly assigned to either control group (multimodal analgesia) or intervention group (intermittent boluses of subcostal QLB plus multimodal analgesia)...

BACKGROUND: A conclusive evidence regarding the optimal concentration and volume of local anesthetic for quadratus lumborum block is lacking. METHODS: In this single-center, prospective, randomized, controlled study, 60 patients scheduled for laparoscopic colorectal surgery were randomly assigned to 3 different combinations of volume and concentration of ropivacaine (3 mg/kg) - Group 0.25%, Group 0.375% and Group 0.5%. All subjects received ultrasound-guided posterior quadratus lumborum block prior to the induction...

DESIGN: A cadaveric examination that evaluates the spread of QIP block. SETTING: Cadaver laboratory. PATIENTS: One unembalmed cadaver. INTERVENTIONS: Bilateral ultrasound-guided QIP blocks on cadavers with 40 mL of methylene blue %0.5 each side...

BACKGROUND: Patients diagnosed with Heart Failure with Reduced Ejection Fraction (HFrEF) are at high risk of perioperative cardiovascular complications. While it is important to focus on optimizing their cardiac function, it is also crucial to address and optimize any other modifiable risk factors that could potentially impact postoperative outcome. This also includes careful consideration of anesthetic techniques to suit the patient and facilitate the surgery. However, there is a scarcity of evidence regarding the safety of specific anesthetic approaches for heart failure patients...

In the past, quadratus lumborum block (QLB) was mostly used for postoperative analgesia in patients, and few anesthesiologists applied it during surgery with opioid-free anesthesia (OFA). Consequently, it is still unclear whether QLB in the supine position can provide perfect analgesia and inhibit anesthetic stress during surgery under the OFA strategy. To observe the clinical efficacy of ultrasound-guided quadratus lumborum block (US-QLB) in the supine position with OFA for lower abdominal and pelvic surgery...

Over 80% of surgical patients experience postoperative pain, which, if inadequately managed, can lead to complications, prolonged rehabilitation, chronic pain, and decreased quality of life. Epidural block and quadratus lumborum block are techniques commonly used for postoperative pain management. This comparative analytic study aimed to analyze the differences in the analgesic effects of quadratus lumborum block and epidural block in uterine surgery at Dr. Soetomo General Hospital. The outcomes assessed were the numerical rating score (NRS) as a pain score and the administration of opioids as an adjuvant analgesic...

BACKGROUND: Acute and chronic postoperative pain are important healthcare problems, which can be treated with a combination of opioids and regional anaesthesia. The erector spinae plane block (ESPB) is a new regional anaesthesia technique, which might be able to reduce opioid consumption and related side effects. OBJECTIVES: To compare the analgesic effects and side effect profile of ESPB against no block, placebo block or other regional anaesthetic techniques. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and Web of Science on 4 January 2021 and updated the search on 3 January 2022...

Quadratus lumborum block (QLB) has been described as a regional analgesic technique in various abdominal surgeries. We present a case report of a high-risk patient who underwent ovarian cystectomy with QLB and deep sedation after failed neuraxial anesthesia. A 29-year-old female patient with comorbidities osteogenesis imperfecta, severe kyphoscoliosis with restrictive lung disease, and cervical syringomyelia with cranio-cervical junction stenosis (C2/C3). The patient had large ovarian cysts with associated dyspnea...

Surgeons performing hip arthroscopy (HA) continue to look for solutions to address immediate postoperative pain and achieve a safe and efficient same-day discharge. Multiple studies have looked at modalities to achieve this, and we have learned that some methods are successful whereas others have a high-risk profile and should be avoided. The pericapsular nerve group (PENG) block is at the forefront of the literature. The PENG block is an easy-to-perform pericapsular nerve block that has been shown in prospective and retrospective studies to decrease acute postoperative pain...

BACKGROUND: This analysis aimed to explore the analgesic effects of quadratus lumborum block on acute and chronic postoperative pain among patients undergoing cesarean section. METHODS: PubMed, Cochrane, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, and VIP databases for Randomized Controlled Trials (RCTs) that focused on the use of quadratus lumborum block in cesarean section procedures were searched from the inception of the databases until December 2022...

BACKGROUND: Ultrasound-guided quadratus lumborum block (QLB) and sacrococcygeal epidural anaesthesia (ScE) have been used for neutering cats, providing effective pain relief. OBJECTIVES: To compare the effects of the QLB with those of ScE in cats undergoing ovariectomies. METHODS: Feral cats undergoing ovariectomy were premedicated with dexmedetomidine (20 μg kg-1 ) and methadone (0.2 mg kg-1 ) intramuscularly. Anaesthesia was induced with 2-4 mg kg-1 of propofol intravenously and maintained with isoflurane in oxygen...

BACKGROUND: Acetabular fracture surgeries are frequently accompanied by protracted and severe perioperative pain, and there is no consensus on optimal pain relief management. AIM: This study aimed at comparing the analgesic efficacy of fascia iliaca compartment block (FICB) and quadratus lumborum block (QLB) in patients with acetabular fractures undergoing surgery using the Stoppa method. METHODS: In this double-blind, randomized, noninferiority clinical trial, adult patients undergoing spinal anesthesia for acetabular fracture surgery, in Imam Hossein Hospital, Tehran, Iran (IRCT20191114045435N1), were randomly divided into two groups: FICB ( n  = 22) and QLB ( n  = 24)...

BACKGROUND: Total hip arthroplasty (THA) is one of the most common operative procedures performed. Controlling postoperative pain following THA remains a challenge due to the complex innervation of the hip joint and the recent desire to preserve motor function following nerve blockade. Several nerve block techniques have been used for THA in the past, but the quadratus lumborum (QL) block and the blockade of the pericapsular nerve group (PENG) have emerged as opiate-sparing regional anesthesia techniques that preserve motor function...

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...
