Back pain and neuraxial

BACKGROUND: Primary spinal cord tumors, especially primary spinal cord glioblastoma multiforme (PSC-GBM), are exceptionally rare, accounting for less than 1.5% of all spinal tumors. Their infrequency and aggressive yet atypical presentation make diagnosis challenging. In uncertain cases, a surgical approach for tissue diagnosis is often optimal. OBSERVATIONS: A 76-year-old male presented with a rapidly progressing clinical history marked by worsening extremity weakness, urinary retention, and periodic fecal incontinence alongside diffuse changes on neuraxis imaging...

PURPOSE OF REVIEW: This review article explores the potential longer-term implications of neuraxial analgesia in labour for both the mother and her child. RECENT FINDINGS: Neuraxial techniques for labour analgesia are well tolerated and effective, and long-term adverse sequelae are rare. Labour epidural analgesia is not independently associated with long-term headache, backache, postnatal depression or anal sphincter injury, and evidence supports that epidurals may offer protection against severe maternal morbidity, particularly in women at a higher risk of complications...

In current clinical practice, spinal anesthesia and analgesia techniques-including epidural and subarachnoid procedures-are frequently executed without imaging like X-ray or epidurography. Unrecognized spinal pathology has resulted in serious morbidity in the context of performing neuraxial anesthesia. Typically, preoperative consultations incorporate a patient's medical history but lack a detailed spinal examination or consideration of recent MRI or CT scans. In contrast, within the domain of pain clinics, a multidisciplinary approach involving anesthesiologists and neuroradiologists is common...

INTRODUCTION: Cavernomas are rare vascular lesions that can occur anywhere along the neuraxis. However, they are most commonly found in the cerebral hemispheres. Spinal cavernomas are more uncommon and intradural extramedullary cavernomas are the most uncommon as they constitute only 3 % of spinal cavernomas. PRESENTATION: A 36-year-old female presented to our neurosurgical clinic with a history of back pain radiating to the left side of the chest with left lower extremity paresthesia and ataxia without urinary disturbance...

We report a rare complication of an inadvertent dural puncture in an obstetric patient. A 24-year-old healthy primipara had a difficult neuraxial labor analgesia insertion. Subsequently she developed severe back pain and started having 'electric shock'-like sensations radiating from the spine to the lower extremities, raising a suspicion of a vertebral canal hematoma. Topping up the epidural for emergency cesarean section was unsuccessful and the surgery was done under general anesthesia. Subsequent emergency magnetic resonance imaging (MRI) of the spine showed no signs of bleeding but her symptoms persisted, and a repeat MRI of the spine ultimately revealed substantial epidural fluid collection extending from the cervical level to the lower thoracic spine, with signs of intracranial hypotension in the MRI of the brain...

INTRODUCTION: First-line pain treatment is unsatisfactory in more than 50% of chronic pain patients, likely because of the heterogeneity of mechanisms underlying pain chronification. OBJECTIVES: This cross-sectional study aimed to better understand pathomechanisms across different chronic pain cohorts, regardless of their diagnoses, by identifying distinct sensory phenotypes through a cluster analysis. METHODS: We recruited 81 chronic pain patients and 63 age-matched and sex-matched healthy controls (HC)...

Objective This study examined the interaction between adolescent idiopathic scoliosis (AIS) and pregnancy, focusing on pregnancy outcomes, changes in back pain, and anesthesia use. Methods A retrospective analysis was conducted on adult patients with AIS who gave birth at our institution between 2006 and 2022. Results A total of 163 AIS patients with 263 pregnancies were included. The median age at delivery was 33 (range 18 to 50) years. Among 157 patients with information on prior scoliosis treatment, 66.9% had not received treatment, 20...

Spontaneous retroperitoneal hematomas are a rare yet potentially devastating occurrence associated with antiplatelet and anticoagulant therapies. We present a case of a spontaneous retroperitoneal hematoma post-operatively after a total hip arthroplasty surgery performed under a midline approach spinal anesthetic. A 79-year-old male with a BMI of 25.72 kg/m2 presented for anterior total hip arthroplasty. A midline approach with an uncomplicated spinal anesthetic was performed. On the night of postoperative day 0, the patient received a prophylactic dose of dalteparin...

BACKGROUND: The erector spinae plane block (ESPB) is a less invasive, safer, and technically easier procedure compared to the conventional neuraxial technique. Although the ESPB is a favored and easy technique compared to neuraxial block, there is no study with a large number of patients describing the exact spread level of injected local anesthetics. OBJECTIVES: The purpose of this study was to identify ESPB spread in the craniocaudal direction and the incidence of spread into the epidural space, psoas muscle, and intravascular system...

The use of neuraxial procedures, such as spinal and epidural anaesthesia, has been linked to some possible complications. In addition, spinal cord injuries due to anaesthetic practice (Anaes-SCI) are rare events but remain a significant concern for many patients undergoing surgery. This systematic review aimed to identify high-risk patients summarise the causes, consequences, and management/recommendations of SCI due to neuraxial techniques in anaesthesia. A comprehensive search of the literature was conducted in accordance with Cochrane recommendations, and inclusion criteria were applied to identify relevant studies...

BACKGROUND: The development of back pain following epidural analgesia is one reason for patient refusal of neuraxial analgesia. The primary endpoint of this study was to compare the incidence and severity of back pain following midline and paramedian epidural technique. The secondary endpoint was to identify the risk factors associated with the occurrence of back pain. METHODS: This prospective randomized study included 114 patients receiving thoracic epidural catheterization for pain management following upper abdominal or thoracic surgery...

BACKGROUND: The effects of lumbar flexion on posterior longitudinal ligament (PLL) length as an acoustic window for neuraxial block in older patients have not been fully elucidated. OBJECTIVE: This study aimed to compare changes in PLL length during lumbar spine flexion in young and old patients. STUDY DESIGN: Observational cohort study. SETTING: Tertiary University Hospital. METHODS: Forty young and older adult patients were placed in the lateral decubitus position...

Various techniques for regional anesthesia and analgesia of the thorax are currently being used in clinical practice. A recent international consensus has anatomically classified paraspinal blocks in the thoracic spinal region into the following four types: paravertebral, retrolaminar, erector spinae plane, and intertransverse process blocks. These blocks have different anatomical targets; thus, the spreading patterns of the injectates differ and can consequently exhibit different neural blockade characteristics...

Background and Aim: The aim of this study is to investigate the magnetic resonance imaging (MRI) of patients with lumbar disc herniation (LDH) to identify the challenges associated with neuraxial anesthesia. Materials and Methods: The MRI images in the supine position of 203 patients admitted to hospital with complaints of lower back pain were studied. Medial sagittal slices of the lumbar spine were imaged from L1 to S1. LDH is classified as either bulging, extrusion, or protrusion...

BACKGROUND: Unintentional dural puncture with an epidural needle complicates approximately 1% of epidural anaesthetics and causes an acute headache in 60-80% of these patients. Several retrospective studies suggest an increased risk of chronic headache. We assessed the relationship between unintentional dural puncture and chronic disabling headache, defined as one or more functionally limiting headaches within a 2-week interval ending 2, 6, and 12 months postpartum. METHODS: In this prospective observational study, parturients who experienced unintentional dural puncture were matched 1:4 with control patients...

Some pregnant women use capsaicin patches placed on the lower back as pain relief during labour. The effect of prescription capsaicin patches for treatment of neuropathic pain is pharmacologically documented. There are no studies on the effect of capsaicin patches on labour pain. In this case report, capsaicin patches placed on the lower back prevented epidural analgesia during labour and spinal anaesthesia for suturing of perineal rupture due to oedema and erythema of the skin. Due to lack of evidence, neuraxial anaesthesia after the use of capsaicin patches on the lower back are contraindicated...

BACKGROUND: Subdural anesthesia and spinal subdural hematoma are rare complications of combined spinal-epidural anesthesia. We present a patient who developed both after multiple attempts to achieve combined spinal-epidural anesthesia. CASE PRESENTATION: A 21-year-old parturient, gravida 1, para 1, with twin pregnancy at gestational age 34+ 5 weeks underwent cesarean delivery. Routine combined spinal-epidural anesthesia was planned; however, no cerebrospinal fluid outflow was achieved after several attempts...

Fever and low back pain with radicular symptoms raise concern for epidural abscess or other neuraxial infection, especially in the context of recent epidural anesthesia. Here we present an unusual case with several confounding factors and an unexpected diagnosis.

PURPOSE OF REVIEW: Postpartum headache is a common occurrence with various obstetric, neurologic, and anesthetic etiologies. Post dural puncture headache (PDPH) after neuraxial anesthesia is a culprit that may be less familiar to obstetricians. In this review, authors will discuss the differential diagnosis and management of postpartum headache, review PDPH, and explore evidence suggesting that PDPH may have greater implications than previously considered. RECENT FINDINGS: Emerging evidence suggests that PDPH, previously believed to be benign and self-limited, is associated with significant acute and chronic sequelae...

BackgroundDisease-modifying anti-rheumatic drugs (DMARDs) are used in the management of rheumatoid arthritis (RA) and are classified as conventional DMARDs and biologic agents. A concern with DMARDs is the increased risk of infection after surgery. A practice advisory from the American Society of Anesthesiologists recommend alternatives to neuraxial injections in patients who are immunocompromized. We describe a patient who was on several DMARDs and developed inflammatory reactions in her bilateral paraspinal muscles and lumbar spine after an epidural steroid injection (ESI)...
