BACKGROUND AND OBJECTIVES: Percutaneous peripheral nerve stimulation (PNS) is an analgesic modality involving the insertion of a lead through an introducing needle followed by the delivery of electric current. This modality has been reported to treat chronic pain as well as postoperative pain the day following knee surgery. However, it remains unknown if this analgesic technique may be used in ambulatory subjects following foot procedures beginning within the recovery room immediately following surgery, and with only short series of patients reported to date, the only available data are derived from strictly observational studies...

Animal data have demonstrated increased block duration after local anaesthetic injections in diabetic rat models. Whether the same is true in humans is currently undefined. We, therefore, undertook this prospective cohort study to test the hypothesis that type-2 diabetic patients suffering from diabetic peripheral neuropathy would have increased block duration after ultrasound-guided popliteal sciatic nerve block when compared with patients without neuropathy. Thirty-three type-2 diabetic patients with neuropathy and 23 non-diabetic control patients, scheduled for fore-foot surgery, were included prospectively...

BACKGROUND: Neuraxial anesthesia is often viewed as superior to general anesthesia but may delay discharge. Comparisons do not typically use multimodal analgesics and nerve blockade. Combining nerve blockade with general anesthesia may reduce pain, opioid consumption, and nausea. We hypothesized that general anesthesia (with nerve blocks) would lead to earlier readiness for discharge, compared to spinal anesthesia (with nerve blocks). METHODS: All patients underwent ambulatory foot and ankle surgery, with a predicted case duration of 1-3 hours...

BACKGROUND: The demand for total knee arthroplasty (TKA) is rising worldwide. Controversy persists in the literature regarding the benefits of general vs. neuraxial anesthesia and which anesthetic is associated with the best outcomes. Likewise, the abundance of analgesic options for post-TKA pain have led to debate regarding the safest, most effective regimens. METHODS: In this narrative review, we evaluated a selection of recent publications regarding anesthetic and analgesic choices for TKA...

INTRODUCTION: An obturator nerve block (ONB) and a femoral triangle block (FTB) provide effective analgesia after total knee arthroplasty (TKA) without impeding the ambulation, although the ONB produces motor blockade of the hip adductor muscles. The popliteal plexus (PP) in the popliteal fossa is formed by contribution from the tibial nerve and the posterior obturator nerve, innervating intraarticular genicular structures and the posterior capsule of the knee. We hypothesised that a popliteal plexus block (PPB) as a supplement to an FTB would reduce pain after TKA without anaesthetising motor branches from the sciatic nerve in the popliteal fossa...

BACKGROUND: This systematic review examines the benefit and harm of adding epinephrine to local anesthetics for epidural, intrathecal, or locoregional anesthesia. METHODS: We searched electronic databases to October 2017 for randomized trials comparing any local anesthetic regimen combined with epinephrine, with the same local anesthetic regimen without epinephrine, reporting on duration of analgesia, time to 2 segments regression, or any adverse effects. Trial quality was assessed using the Cochrane risk of bias tool and a random-effects model was used...

T cell-mediated responses have been implicated in the development of fibrosis, impaired lymphangiogenesis, and lymphatic dysfunction in secondary lymphedema. Here we show that CD4+ T cells are necessary for lymphedema pathogenesis by utilizing adoptive transfer techniques in CD4 knockout mice that have undergone tail skin and lymphatic excision or popliteal lymph node dissection. We also demonstrate that T cell activation following lymphatic injury occurs in regional skin-draining lymph nodes after interaction with antigen-presenting cells such as dendritic cells...

BACKGROUND: Adductor canal block (ACB) is a peripheral nerve blockade technique that provides good pain control in patients undergoing total knee arthroplasty which however does not relieve posterior knee pain. The recent technique of an ultrasound-guided local anesthetic infiltration of the interspace between popliteal artery and the capsule of posterior knee (IPACK) has shown promising results in providing significant posterior knee analgesia without affecting the motor nerves. MATERIALS AND METHODS: A prospective study was conducted from September 2016 to March 2017 in a total of 120 patients undergoing unilateral total knee arthroplasty...

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...

Regional anaesthesia is widely used in modern anaesthetic practice for perioperative and postoperative analgesia. In the operating theatre, regional anaesthesia is used both on its own and in combination with other techniques (general anaesthesia and sedation). Regional anaesthesia is now a core skill set in anaesthetic training. This article provides a basic outline of regional anaesthesia for surgeons and other non-anaesthetic staff working with anaesthetists, reviewing preparation, consent, basic and specialist equipment, central neuraxial blocks (spinal, epidural and caudal), trunk blocks, upper limb blocks (interscalene, supraclavicular, infraclavicular and axillary) and lower limb blocks (femoral, fascia iliaca, sciatic, popliteal and ankle)...

BACKGROUND: Single or combined multiple-site peripheral nerve blocks (PNBs) are becoming popular for patients undergoing surgery on their feet or ankles. These procedures are known to be generally safe in surgical settings compared with other forms of anesthesia, such as spinal block. The purposes of this study were to assess the incidence of complications after the administration of multiple PNBs for foot and ankle surgery and to compare the rates of complications between patients who received a single PNB and those who received multiple blocks...

In recent years, the frequency of high-risk kidney transplantations has increased. We report a case in which a 72-year-old man with various severe comorbidities (prostate cancer, diabetes mellitus, complete atrioventricular block, coronary artery stenosis, severe stenosis of the popliteal arteries, and severe calcification of the iliac arteries) who received an orthotopic kidney transplantation. To prevent the occurrence of acute limb ischemia due to the steal phenomenon (caused by the kidney graft), we decided that a heterotopic kidney transplantation involving the iliac arteries was not an appropriate option...

Purpose: We compared adductor canal block (ACB) alone and a combination of ACB and sciatic nerve block (SNB) to control early postoperative pain after total knee arthroplasty. Materials and Methods: One hundred patients received continuous ACB alone (group A), and another 100 patients received continuous ACB and single popliteal SNB (group B). Pain was evaluated at rest and 45° knee flexion using the numeric rating scale (NRS). The number of times the patient pressed the intravenous patient-controlled analgesia (PCA) button, total PCA volume infused, and the total dosage of additional analgesics were evaluated...

Kinin B1 receptor (B1R) enhanced superoxide anion ([Formula: see text]) production in the vasculature of diabetic rats. This study investigates the induction and distribution of B1R in diabetic blood vessels and addresses the hypothesis that B1R is co-localized with NADPH oxidase (NOX1 and NOX2) and produces its activation via protein kinase C (PKC). Diabetes was induced in rats with streptozotocin (STZ 65 mg.kg-1 , i.p.). Two weeks later, the production of [Formula: see text] was measured in aorta rings in response to the B1R agonist (Sar[D-Phe8 ]-des-Arg9 -BK, 20 μM) by the method of lucigenin-enhanced chemiluminescence...
