Long-acting peripheral nerve blocks provide effective postoperative pain management, but there are risks associated with rendering an extremity insensate. Perianesthesia nurses play a major role in anticipating and mitigating risks and carefully monitoring patients for potential complications. This article presents uncommon but important considerations related to the care of patients with a peripheral nerve block. These include compartment syndrome, local anesthetic systemic toxicity, thermal injuries, falls, and fractures as well as their management and prevention...

Migraine headaches make up a significant proportion of emergency department visits. There are multiple pharmacologic treatment modalities for migraine abortive therapy; however, these treatments are rarely targeted to the precise area of pain and thus elicit multiple systemic effects. It has been well established in the anesthesia pain literature that occipital nerve blocks can provide not only immediate pain relief from occipital migraines, but can also result in a long-term resolution of occipital migraines...

BACKGROUND: Locoregional anaesthetic techniques can facilitate certain surgeries being performed under standing procedural sedation. The second and third spinal cervical nerves (C2, C3) are part of the cervical plexus and provide sensory innervation to the peri-laryngeal structures in people; block of these nerves might permit laryngeal lateralisation surgery in horses. OBJECTIVES: To describe the anatomical basis for an ultrasound-guided cervical plexus block in horses...

Neuropeptide Y (NPY) plays an important role in the regulation of energy homeostasis in the level of central and sympathetic nervous systems (SNSs). Genetic silencing of peripheral Y2 -receptors have anti-obesity effects, but it is not known whether pharmacological blocking of peripheral Y2 -receptors would similarly benefit energy homeostasis. The effects of a peripherally administered Y2 -receptor antagonist were studied in healthy and energy-rich conditions with or without excess NPY. Genetically obese mice overexpressing NPY in brain noradrenergic nerves and SNS (OE-NPYDβH ) represented the situation of elevated NPY levels, while wildtype (WT) mice represented the normal NPY levels...

BACKGROUND: Patients suffering from adult lumbar degenerative scoliosis (ALDS) are commonly complicated with advanced age, osteoporosis, cardiopulmonary insufficiency, and some other medical comorbidity. Therefore, the traditional open surgery can lead to high rate of postoperative complications. The purposes of this study were to introduce our experiences and explore the efficacy and feasibility of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in the treatment of patients with ALDS...

There are few data available that describe the current anaesthetic management of children. We have analysed anaesthetic practice and peri-operative complications for children in Denmark aged less than two years. We conducted a population-based observational cohort study using the Danish Anaesthesia Database to identify children who received anaesthesia in hospital from 1 January 2005 until 31 December 2015. Data were combined with that from the Danish National Patient Registry and the Danish Civil Registration System...

The neurochemical effects of adenosine signaling in small-fiber neuropathy leading to neuropathic pain are yet to be explored in a direct manner. This study examined this system at the level of ligand (via the ectonucleotidase activity of prostatic acid phosphatase, PAP) and adenosine A1 receptors (A1Rs) in resiniferatoxin (RTX) neuropathy, a peripheral neurodegenerative disorder which specifically affects nociceptive nerves expressing transient receptor potential vanilloid type 1 (TRPV1). We conducted immunohistochemistry on dorsal root ganglion neurons (DRG), high-performance liquid chromatography (HPLC) for functional assays, and pharmacological interventions to alter PAP and A1Rs in mice with RTX neuropathy...

Peripheral nerve injury causes maladaptive plasticity in the central nervous system and induces chronic pain. In addition to the injured limb, abnormal pain sensation can appear in the limb contralateral to the injury, called mirror image pain. Since synaptic remodeling in the primary somatosensory cortex (S1) has critical roles in the induction of chronic pain, cortical reorganization in the S1 ipsilateral to the injured limb may also accompany mirror image pain. To elucidate this, we conducted in vivo two-photon calcium imaging of neuron and astrocyte activity in the ipsilateral S1 following a peripheral nerve injury...

Intraoperative tourniquet-related pain is well recognized by anesthesiologists, but postoperative tourniquet-related pain has received little attention. We present a patient who underwent a total knee arthroplasty under general anesthesia and an adductor canal nerve block. She complained of intractable thigh pain postoperatively. Lidocaine 5% patches completely resolved her postoperative tourniquet-related pain.

OBJECTIVES: Neurogenic cough is believed to result from a sensory neuropathy involving the internal branch of the superior laryngeal nerve (SLN). We present our outcomes for the treatment of neurogenic cough with localized blockade of the internal branch of the SLN. METHODS: A retrospective chart review of patients who underwent in-office percutaneous SLN block for treatment of neurogenic cough between 2015 and 2017 was conducted. Patient demographics, indications for injection, and response to treatment were recorded and analyzed...

BACKGROUND AND OBJECTIVES: Major ankle surgery causes intense postoperative pain, and whereas the importance of a sciatic nerve block is well established, the clinical significance of a supplemental saphenous nerve block has never been determined in a prospective, randomized, double-blind, placebo-controlled trial. We hypothesized that a saphenous nerve block reduces the proportion of patients experiencing significant clinical pain after major ankle surgery. METHODS: Eighteen patients were enrolled and received a popliteal sciatic nerve block...

Phantom limb pain is a restricting condition for a substantial number of amputees with quite different characteristics of pain. Here, we report on a forearm amputee with constant phantom pain in the hand, in whom we could regularly elicit the rare phenomenon of referred cramping phantom pain by touching the face. To clarify the underlying mechanisms, we followed the cramp during the course of an axillary blockade of the brachial plexus. During the blockade, both phantom pain and the referred cramp were abolished, while a referred sensation of "being touched at the phantom" persisted...

In daily clinical practice, there is a growing number of patients receiving new biological agents used in the treatment of malignancies. Ipilimumab is a fully humanized monoclonal antibody approved for patients with melanoma. It acts as an immune checkpoint inhibitor, binding and blocking cytotoxic T-lymphocyte antigen-4 in order to increase the antitumor immune response. There are several reports of autoimmune responses after its use. A 74-year-old man developed a mild rash and pruritus a few hours after the second infusion of ipilimumab and 24 h after the third dose of ipilimumab, he presented with shortness of breath, proximal limb muscle weakness, and diplopia...

BACKGROUND: Anatomical knowledge dictates that regional anaesthesia after total hip arthroplasty requires blockade of the hip articular branches of the femoral and obturator nerves. A direct femoral nerve block increases the risk of fall and impedes mobilisation. We propose a selective nerve block of the hip articular branches of the femoral nerve by an ultrasound-guided injection in the plane between the iliopsoas muscle and the iliofemoral ligament (the iliopsoas plane). The aim of this study was to assess whether dye injected in the iliopsoas plane spreads to all hip articular branches of the femoral nerve...

Netrins are secreted chemoattractants with the roles in axon guidance, cell migration and epithelial plasticity. In the present study, we investigated the roles of netrin-1 in the regulation of corneal epithelial wound healing, inflammation response and nerve fiber regeneration in diabetic mice and cultured corneal epithelial cells. In diabetic mice, the expression of netrin-1 was decreased when compared with that of normal mice. Furthermore, high glucose blocked the wounding-induced up-regulation of netrin-1 expression in corneal epithelial cells...

DHTKD1, a part of 2-ketoadipic acid dehydrogenase complex, is involved in lysine and tryptophan catabolism. Mutations in DHTKD1 block the metabolic pathway and cause 2-aminoadipic and 2-oxoadipic aciduria (AMOXAD), an autosomal recessive inborn metabolic disorder. In addition, a nonsense mutation in DHTKD1 we identified previously causes Charcot-Marie-Tooth disease (CMT) type 2Q, one of the most common inherited neurological disorders affecting the peripheral nerves in the musculature. However, the comprehensive molecular mechanism underlying CMT2Q remains elusive...
