INTRODUCTION: Several techniques for the transversus abdominis plane (TAP) block have been described. The extent of sensory changes using an ultrasound-guided posterior TAP block (pTAP) remains unclear in pediatric patients. The primary aim of this study was to report the extent of sensory changes achieved with pTAP; specifically the highest thoracic dermatome anesthetized. Secondary outcomes were pain scores (PS), opioid consumption, and complications. METHODS: We retrospectively reviewed the medical records of patients less than 21 years of age undergoing abdominal surgery with a unilateral or bilateral pTAP(s) for postoperative analgesia...

INTRODUCTION: Most ligaments of the human body have been well studied. However, the lumbocostal ligament has received little attention in the extant medical literature and, to our knowledge, has not undergone anatomical study. Therefore, the present study was performed to better characterize this structure's anatomy and relationships. METHODS: In the prone position, 10 adult cadavers underwent dissection of their lumbocostal ligaments. All specimens were unembalmed and had no history of surgery to the spine...

Quadratus lumborum (QL) block was first described several years ago, but few articles have been published regarding this technique, for the most part case series involving abdominal surgery. We report 2 cases of prolonged, extensive block of thoracic and lumbar dermatomes after QL block in patients undergoing different hip surgery procedures for whom QL block was used in place of lumbar plexus block. Further prospective studies comparing these 2 techniques are necessary to better characterize the role of QL block in hip surgery...

BACKGROUND AND OBJECTIVES: The quadratus lumborum blockade was described by R. Blanco in its two approaches (I and II). The local anesthetic deposition in this location can provide blockade to T6-L1 dermatomes. We performed this fascia blockade guided by ultrasound for treating a chronic neuropathic pain in the abdominal wall. CASE REPORT: Male patient, 61 years old, 83kg, with a history of thrombocytopenia due to alcoholic cirrhosis, among others; had chronic pain in the abdominal wall after multiple abdominal hernia repairs in the last year and a half, with poor response to treatment with neuromodulators and opioids...

OBJECTIVE: Currently, there is a lack of objective means to quantify myofascial trigger points (MTrPs) and their core features. Our research compares (1) MTrPs and surrounding myofascial tissue using two-dimensional grayscale ultrasound (2DGSUS) and vibration sonoelastography (VSE); (2) the accuracy of both modes in visualizing MTrPs; (3) 'active' and 'latent' MTrPs, using VSE; and (4) the accuracy of both modes in visualizing deep and superficially located MTrPs. METHODS: Fifty participants with more than two MTrPs in their quadratus lumborum, longissimus thoracis, piriformis, and gluteus medius muscles were assigned to an active MTrP (low back pain) group or a latent (currently pain free) MTrP group...

The purpose of this study was to investigate the short-term effect of kettlebell swings (KBSs) on lumbopelvic pressure pain thresholds (PPTs) in healthy adults. Sixty participants (male=23, female=37, mean age=25.12 years ±2.86, height=170.73 cm ± 9.2, mass=70.49 kg ± 13.32) were randomized into one of two groups. The experimental group performed a warm-up followed by eight consecutive 20-second rounds of KBS with 10-second rest periods. The control group performed the warm-up alone. An evaluator blinded to group assignment, assessed PPTs immediately before and after the intervention using a handheld pressure algometer...

M Wikner
Quadratus lumborum block has recently been described as an effective and long-lasting analgesic strategy for various abdominal operations, including gynaecological laparoscopy. Despite evidence that the analgesic effect is mediated by indirect paravertebral block and that local anaesthetic spreads to the lumbar paravertebral space, there have been no reports to date of lower limb motor weakness. We present a patient with unilateral hip flexion and knee extension weakness leading to unplanned overnight admission following lateral quadratus lumborum block with 20 ml levobupivacaine 0...

The practice of regional anaesthesia is rapidly changing with the introduction of ultrasound into the working domain of the anaesthesiologist. New techniques are being pioneered. Among the recent techniques, notable are the truncal blocks, for example, the transversus abdominis plane block, rectus sheath block, hernia block and quadratus lumborum block in the abdomen and the pectoral nerves (Pecs) block 1 and 2, serratus anterior plane block and intercostal nerve block. This narrative review covers the brief anatomical discourse along with technical description of the ultrasound-guided truncal blocks...

BACKGROUND AND OBJECTIVES: Effective postoperative analgesia after cesarean delivery enhances early recovery, ambulation, and breastfeeding. In a previous study, we established the effectiveness of the quadratus lumborum block in providing pain relief after cesarean delivery compared with patient-controlled analgesia (morphine). In the current study, we hypothesized that this method would be equal to or better than the transversus abdominis plane block with regard to pain relief and its duration of action after cesarean delivery...

A continuous peripheral nerve block (CPNB) consists of a percutaneously inserted catheter with its tip adjacent to a target nerve/plexus through which local anesthetic may be administered, providing a prolonged block that may be titrated to the desired effect. In the decades after its first report in 1946, a plethora of data relating to CPNB was published, much of which was examined in a 2011 Anesthesia & Analgesia article. The current update is an evidence-based review of the CPNB literature published in the interim...

We performed bilateral transmuscular quadratus lumborum blocks in six cadavers using iodinated contrast and methylene blue. Computed tomography imaging was performed in four cadavers and anatomical dissection was completed in five. This demonstrated spread to the lumbar paravertebral space in 63% of specimens, laterally to the transversus abdominis muscle in 50% and caudally to the anterior superior iliac spine in 63% of specimens. There was no radiographic evidence of spread to the thoracic paravertebral space...

BACKGROUND: Minimal longitudinal data exist regarding the role of lumbar musculature in predicting back pain and function. In cross-sectional study designs, there is often atrophy of the segmental multifidus muscle in subjects with low back pain compared with matched controls. However, the cross-sectional design of these studies prevents drawing conclusions regarding whether lumbar muscle characteristics predict or modify future back pain or function. OBJECTIVE: The primary objective of this study is to determine whether the cross-sectional area (CSA) of lumbar muscles predict functional status or back pain at 6- or 12-month follow-up in older adults with spinal degeneration...

INTRODUCTION AND OBJECTIVES: Quadratus Lumborum block was recently described and has already shown good results as an analgesic technique in abdominal surgeries, having the potential to significantly reduce opioids consumption and be a valid alternative to epidural catheter. We performed a type II Quadratus Lumborum block for analgesia in a septic patient having a sub-total gastrectomy. CASE REPORT: An 80 year-old, ASA III, male patient, weighting 50kg, with a history of arterial hypertension and hypercholesterolemia, diagnosed with sepsis due to purulent peritonitis was submitted to an open laparotomy...

OBJECTIVE: Pisa syndrome (PS) is a common abnormal posture of the trunk in Parkinson disease which is defined as a lateral flexion of the spine in the coronal plane and/or scoliosis. Few studies described focal treatment of dystonia of paraspinal muscles, with unpredictable results, while the participation of quadratus lumborum and external oblique homolateral seem to be interesting. The aim of this study is to estimate the effects of treatment by botulinum toxin of trunk muscles dystonia in PS...
