PURPOSE: To demonstrate feasibility and safety of ultrasound-guided popliteal sciatic nerve block for providing analgesia during urgent endovascular treatment of critical limb ischemia with resting pain. MATERIALS AND METHODS: Ultrasound-guided popliteal sciatic blocks were performed by an interventional radiologist in angiography suite immediately prior to commencement of urgent endovascular treatment of 30 critical limb ischemia patients. Subjective pain levels prior to and following sciatic block were assessed using the visual analog scale (VAS)...

BACKGROUND: Previous studies have documented that single injection nearby the sciatic nerve bifurcation would influence the anesthesia and analgesia effect. But this is uncertain for preoperative continuous popliteal sciatic nerve block. So we conducted this trial to compare two paths (proximal to the bifurcation and at the bifurcation) of ultrasound guided continuous popliteal sciatic nerve block in foot and ankle surgery. METHODS: 40 recruited objects were randomly assigned to receive ultrasound-guided continuous popliteal sciatic nerve block at the puncture path proximal to the nerve bifurcation either at the nerve bifurcation...

BACKGROUND: Novel regional techniques, including the adductor canal block (ACB) and the local anesthetic infiltration between the popliteal artery and capsule of the knee (IPACK) block, provide an alternative approach for controlling pain following total knee arthroplasty (TKA). This study compared 3 regional techniques (femoral nerve catheter [FNC] block alone, FNC block with IPACK, and ACB with IPACK) on pain scores, opioid consumption, performance during physical therapy, and hospital length of stay in patients undergoing TKA...

BACKGROUND AND OBJECTIVES: The popliteal nerve plexus contributes to afferent knee-pain conduction. It is mainly formed by genicular branches from the posterior obturator and the tibial nerves, innervating the intra-articular and posterior knee region. A subinguinal obturator nerve block alleviates pain after total knee arthroplasty. Reduced hip adductor motor function could be avoided by a posterior obturator nerve block inside the popliteal fossa. The aim of this study was to evaluate the spread of dye after a distal adductor canal (AC) injection to the popliteal fossa and coloring of the popliteal plexus and the genicular branch of the posterior obturator nerve by dissection...

BACKGROUND: Postoperative pain is often difficult to control with oral medications, requiring large doses of opioid analgesia. Regional anesthesia may be used for primary anesthesia, reducing the need for general anesthetic and postoperative pain medication requirements in the immediate postoperative period. The purpose of this study was to compare the analgesic effects of an ankle block (AB) to a single-shot popliteal fossa block (PFB) for patients undergoing orthopedic forefoot procedures...

Sickle cell crisis, or vaso-occlusive crisis (VOC), is a major cause of hospitalizations for adults and children with sickle cell disease, and is associated with increased morbidity and mortality. Despite prompt pharmacological treatment and multimodal pain management, acute pain during a VOC is often not adequately controlled in the pediatric population. We placed a continuous popliteal sciatic nerve block under ultrasound guidance in a pediatric patient for localized refractory pain during a VOC, resulting in improved pain control with preserved sensorimotor function...

In our hospital, we introduced a system to measure the collective and individual efficacy of brachial plexus and popliteal nerve blocks with the objective to create transparency as an instrument for monitoring and improvement. Initially, individual results were anonymous, but after 1 year anonymity was lifted within the team of anesthesiologists and results are now discussed quarterly. Collective performance of interscalene, supraclavicular, and popliteal blocks improved significantly over time. Sharing and discussing collective and individual performance has resulted in critical self-appraisal and increased willingness to learn from each other and strengthened the team's ambition for further improvement...

INTRODUCTION: Ankle fracture surgery is a common procedure, but the influence of anaesthesia choice on postoperative pain and quality of recovery is poorly understood. Some authors suggest a benefit of peripheral nerve block (PNB) in elective procedures, but the different pain profile following acute fracture surgery and the rebound pain on cessation of the PNB both remain unexplored. We present an ongoing randomised study aiming to compare primary PNB anaesthesia with spinal anaesthesia for ankle fracture surgery regarding postoperative pain profiles and quality of recovery...

BACKGROUND AND OBJECTIVES: High concentrations of local anesthetics may be neurotoxic for diabetic patients. Additive perineural administration of magnesium was reported to decrease the consumption of local anesthetics for nerve block. It was hypothesized that MgSO4 added to dilute ropivacaine was equianalgesic to more concentrated ropivacaine for toe amputations in diabetic patients. METHODS: Seventy diabetic patients were allocated into 3 groups: 1) perineural 200 mg MgSO4 added to 0...

Approximately 27 million people in Europe and North America currently have peripheral arterial disease (PAD). The endovascular treatment of stenosis or blocked peripheral arteries in PAD include percutaneous transluminal angioplasty with or without a drug coated balloon (DCB), atherectomy (rotational, directional, orbital or laser), and stenting. The development of next generation peripheral stents and drug-coated stents have led to the improved treatment of complex superficial femoral artery (SFA) lesions, and consequently increased their usage...

Neuropathy of the posterior femoral cutaneous nerve may manifest as pain and paresthesia in the skin over the inferior buttocks, posterior thigh, and popliteal region. Current treatment options include physical and oral pain therapy, perineural injections, and surgical neurectomy. Perineural steroid injections may provide short-term pain relief; however, to our knowledge, there is currently no minimally invasive denervation procedure for sustained pain relief that could serve as an alternative to surgical neurectomy...

Background. A recently described selective tibial nerve block at the popliteal crease presents a viable alternative to sciatic nerve block for patients undergoing total knee arthroplasty. In this two-part investigation, we describe the effects of a tibial nerve block at the popliteal crease. Methods. In embalmed cadavers, after the ultrasound-guided dye injection the dissection revealed proximal spread of dye within the paraneural sheath. Consequentially, in the clinical study twenty patients scheduled for total knee arthroplasty received the ultrasound-guided selective tibial nerve block at the popliteal crease, which also resulted in proximal spread of local anesthetic...

INTRODUCTION: Sciatic neuropathy after popliteal nerve block (PNB) for regional anesthesia is considered uncommon but has been increasingly recognized in the literature. We identified a case of sciatic neuropathy that occurred after bunionectomy during which a PNB had been performed. METHODS: To understand the frequency of PNB-related sciatic neuropathy, we performed a retrospective review of sciatic neuropathies at our center over a 5-year period. RESULTS: Forty-five cases of sciatic neuropathy were reviewed...

PURPOSE: The aim of this study was to evaluate the effects of a preoperative popliteal block on sevoflurane consumption, postoperative pain, and analgesic consumption in children with cerebral palsy (CP) following lower limb surgery. METHODS: Fifty-four patients undergoing lower limb surgery were randomized to receive either a popliteal block + general anaesthesia (group P, n = 27) or general anaesthesia without a popliteal block (group C, n = 27). After anesthesia induction with 50% N2O, O2, and 8% sevoflurane, a popliteal block was given to group P patients with ultrasound guidance as a single dose of 0...

Voltage-gated sodium channels (VGSC) regulate neuronal excitability by governing action potential (AP) generation and propagation. Recent studies have revealed that AMP-activated protein kinase (AMPK) activators decrease sensory neuron excitability, potentially by preventing sodium (Na+) channel phosphorylation by kinases such as ERK or via modulation of translation regulation pathways. The direct positive allosteric modulator A769662 displays substantially greater efficacy than other AMPK activators in decreasing sensory neuron excitability suggesting additional mechanisms of action...

BACKGROUND AND OBJECTIVES: The advent of ultrasound has brought many benefits to peripheral nerve blocks. It includes both safety and effectiveness, given the possibility of visualizing the neurovascular structures and the needle during the procedure. Despite these benefits, there is no consensus in the literature on the use of this technique in anticoagulated patients or with other coagulation disorders. Moreover, peripheral blocks vary in depth, spreadability, and possibility of local compression...
