Semiquantitative 131 I MIBG Scintigraphy Predicts Intraoperative Blood Pressure Fluctuation in Patients Undergoing Surgery for Pheochromocytoma and Paraganglioma.

Objective: Severe blood pressure (BP) fluctuation happens during surgery for pheochromocytoma and paraganglioma (PPGL) due to the release of catecholamines. 131 I MIBG scintigraphy indicates the capacity of PPGL to retake and reserve catecholamines. This study aims to utilize 131 I MIBG scintigraphy to predict intraoperative BP fluctuation in patients undergoing PPGL surgery, thereby guiding preoperative preparation.

Utilization of 3D printing modeling techniques in the simulation instruction of ultrasound-guided puncture procedures on scoliotic spines of spinal muscular atrophy.

Background: Puncture training with simulation models has emerged as a critical method for transmitting puncture skills, improving success rates, and minimizing injuries. Yet, obstacles such as proper material for ultrasound guidance, restricted options of 3D printing resources, and available substances to simulate human skin and muscle still hinder the production of simulation models that closely replicate clinical practice. This study aimed to develop a selective laser melting (SLM), 3D-printed simulation model that replicated the spine and skin contours of patients with spinal scoliosis.

Comparative Analysis of Muscle Elasticity and Pathological Characteristics Between Affected and Unaffected Sides in Postherpetic Neuralgia Patients: Protocol for a Pilot Cohort Trail.

Background: Postherpetic neuralgia (PHN) is the most common condition that can develop as a complication after herpes zoster (HZ) infection, characterized by pain that persists for more than 3 months after the initial rash has resolved. In most patients with HZ, the rash appears unilaterally. While the treatment of PHN is primarily focused on neural mechanisms due to HZ's neurotropism nature, recent evidence suggests that muscle tissues within the affected regions may also experience pathological changes that contribute to the pain.

A modified approach of combined anterior lumbar plexus block with lateral sacral plexus block in a semi lateral supine position for lower limb fracture patients: a case series.

Lumbar plexus block (LPB) and sacral plexus block (SPB) are commonly used regional anesthesia techniques for lower limb surgeries. We propose a novel approach combining anterior LPB and lateral SPB in a semi-lateral supine position with a pad under the upper body. This approach minimizes discomfort and pain during position changes, enhances probe manipulation space, and aids in maintaining aseptic conditions throughout the entire operation.

Role of a route map in learning lumbar spinal ultrasonography: a study protocol for a randomised, controlled teaching study.

Introduction: Lumbar spinal ultrasonography is an important tool used by pain physicians and anaesthesiologists to perform pain-related scanning, interventional treatments and anaesthesia in clinical practice. However, ultrasound images of the lumbar spine are complex and numerous. Moreover, long learning curves are necessary for novice physicians to memorise, master and apply this modality in their clinical practice.

Transverse interlaminar ultrasound-guided C1-C2 puncture for the intrathecal administration of nusinersen in patients with spinal muscular atrophy.

Introduction/aims: Severe spinal deformities and previous spinal orthopedic instrumentation may result in substantial technical challenges for nusinersen delivery through lumbar puncture in patients with spinal muscular atrophy (SMA). The aim of this paper was to review our experience with ultrasound-guided cervical puncture as an alternative approach for the intrathecal administration of nusinersen.

Methods: This was a retrospective medical record review of transverse interlaminar ultrasound-guided C1-C2 puncture for nusinersen delivery in SMA patients.

Deep Learning Detection and Segmentation of Facet Joints in Ultrasound Images Based on Convolutional Neural Networks and Enhanced Data Annotation.

The facet joint injection is the most common procedure used to release lower back pain. In this paper, we proposed a deep learning method for detecting and segmenting facet joints in ultrasound images based on convolutional neural networks (CNNs) and enhanced data annotation. In the enhanced data annotation, a facet joint was considered as the first target and the ventral complex as the second target to improve the capability of CNNs in recognizing the facet joint.

Unilateral interlaminar fenestration on the convex side provides a reliable access for intrathecal administration of nusinersen in spinal muscular atrophy: a retrospective study.

Background: As the first gene therapy for spinal muscular atrophy (SMA), nusinersen is supposed to be administrated via intrathecal injection regularly for a lifetime. However, for SMA patients with severe spinal deformities, bony fusion following posterior spinal instrumentation sets great obstacles for the application of nusinersen. Therefore, efforts have been devoted to the exploration of appropriate approach for nusinersen administration.

The effects of intermittent bolus paravertebral block on analgesia and recovery in open hepatectomy: a randomized, double-blinded, controlled study.

Background: We aimed to investigate the effects of intermittent bolus paravertebral block on analgesia and recovery in open hepatectomy.

Methods: Eighty 18-70 years old, American Society of Anesthesiologists level I-III patients scheduled for hepatectomy with a J-shaped subcostal incision were enrolled and randomized to receive either intermittent bolus paravertebral ropivacaine (0.5% loading, 0.

Proposal of a Route Map for Cervical Spinal Ultrasonography: A Simple and Clear Learning Tool for Beginners.

Spinal ultrasonography has increasingly been used to image axial structures from the cervical to sacral region in recent years. In this work, we propose a comprehensive, systematic cervical scanning protocol that we refined as a route map, especially for beginners, to facilitate teaching, learning, diagnosis, and treatment in clinical pain practice. As a simple and clear tool to demonstrate the scanning protocol, the route map is delineated with rectangles, lines, and arrows.

Developing a magnetic POCUS-guided bronchoscope for patients with suspected difficult endotracheal intubation in a general tertiary hospital: protocol for a randomised controlled study.

Introduction: Endotracheal intubation (ETI) is a crucial but risky procedure, especially among patients suspected of difficult endotracheal intubation (DTI). Bronchoscope, as an improved technique commonly used in DTI, might encounter visualisation difficulties. The magnetic point-of-care ultrasound (MGPOCUS) provides a novel visualisation from the outside and enables estimation of the relative position and trajectory of the bronchoscope.

Ultrasound-guided pulsed radiofrequency versus dry needling for pain management in chronic neck and shoulder myofascial pain syndrome patients at a tertiary hospital in China: a randomised controlled trial protocol.

Introduction: Myofascial pain syndrome (MPS), especially in the neck and shoulder region, is one of the most common chronic pain disorders worldwide. Dry needling (DN) and pulsed radiofrequency (PRF) are the two effective methods for treating MPS. We aimed to compare the effects of DN and PRF in chronic neck and shoulder MPS patients.

Comparison of the Postoperative Analgesic Effects between Ultrasound-Guided Transmuscular Quadratus Lumborum Block and Thoracic Paravertebral Block in Laparoscopic Partial Nephrectomy Patients: A Randomized, Controlled, and Noninferiority Study.

Background: This prospective, randomized, double-blinded, noninferiority study aimed to compare the effects of analgesia and recovery between transmuscular quadratus lumborum block (TMQLB) and paravertebral block (PVB).

Methods: Sixty-eight, American Society of Anesthesiologists level I-III patients, who underwent laparoscopic partial nephrectomy in Peking Union Medical College Hospital were randomly allocated to either TMQLB or PVB group (independent variable) in a 1 : 1 ratio. The TMQLB and PVB groups received corresponding regional anesthesia preoperatively with 0.

Automatic detection of A-line in lung ultrasound images using deep learning and image processing.

Background: Auxiliary diagnosis and monitoring of lung diseases based on lung ultrasound (LUS) images is important clinical research. A-line is one of the most common indicators of LUS that can offer support for the assessment of lung diseases. A traditional A-line detection method mainly relies on experienced clinicians, which is inefficient and cannot meet the needs of these areas with backward medical level.

Dyspnea induced by hemidiaphragmatic paralysis after ultrasound-guided supraclavicular brachial plexus block in a morbidly obese patient.

Rationale: Hemidiaphragmatic paralysis (HDP) is a frequent complication of the brachial plexus block, caused by unintentional blockade of ipsilateral phrenic nerve. HDP did not rise enough alarm and attention to most anesthesiologists, because most patients with no coexisting comorbid diseases are asymptomatic and able to tolerate it. However, it may cause severe respiratory complication for patients with preexisting compromised cardiorespiratory function.

Transmuscular quadratus lumborum block for postoperative pain and recovery after laparoscopic adrenalectomy: a randomized controlled trial.

Background: To investigate the role of transmuscular quadratus lumborum block (TMQLB) for postoperative pain control, patient satisfaction and recovery in laparoscopic adrenalectomy.

Methods: Seventy-two patients aged between 18 and 70 years with an ASA I-II and scheduled for laparoscopic adrenalectomy were randomized to receive a single-shot TMQLB with 0.4 ml/kg 0.

Ultrasound-guided nusinersen administration for spinal muscular atrophy patients with severe scoliosis: an observational study.

Background: This observational study describes our experience delivering nusinersen through lumbar puncture with real-time ultrasound guidance in spinal muscular atrophy (SMA) patients with severe scoliosis.

Results: Intrathecal nusinersen via real-time ultrasound-guided lumbar puncture was given to three patients who had severe thoracic and lumbar scoliosis: a 34-year-old female with type 3a SMA, a 28-year-old male with type 2a SMA, and a 14-year-old girl with type 3a SMA. Lumbar puncture was performed without sedation under ultrasound guidance using a 22G echogenic needle in the interlaminar aspect of the L4-L5 or L5-S1 interspace and a full dose of nusinersen (12 mg/5 mL) was injected after visualizing free cerebrospinal fluid flow.

Continuous block at the proximal end of the adductor canal provides better analgesia compared to that at the middle of the canal after total knee arthroplasty: a randomized, double-blind, controlled trial.

Background: The optimal position for continuous adductor canal block (ACB) for analgesia after total knee anthroplasty (TKA) remians controversial, mainly due to high variability in the localization of the the adductor canal (AC). Latest neuroanatomy studies show that the nerve to vastus medialis plays an important role in innervating the anteromedial aspect of the knee and dives outside of the exact AC at the proximal end of the AC. Therefore, we hypothesized that continuous ACB at the proximal end of the exact AC could provide a better analgesic effect after TKA compared with that at the middle of the AC (which appeared to only block the saphenous nerve).
