Popliteal block

Background and Objectives: Total knee arthroplasty (TKA) is a commonly performed orthopedic procedure, and is often accompanied by significant postoperative pain. The supra-inguinal fascia iliaca block (SIFIB), similar to an anterior lumbar plexus block, is frequently used in hip surgeries. The interspace between the popliteal artery and capsule of the posterior knee (IPACK) block is a regional anesthesia technique that targets the posterior innervation of the knee capsule. This retrospective study aimed to compare the analgesic effects of SIFIB and SIFIB + IPACK on patients undergoing TKA under spinal anesthesia...

BACKGROUND: Diabetic foot ulcers (DFUs) represent a significant foot-related concern for patients with multiple co-morbidities, and surgical intervention is often employed. Notably, peripheral nerve block anesthesia (PNB) has emerged as a new approach for the surgical management of DFUs, providing sustained hemodynamic stability and superior postoperative pain control compared to general anesthesia (GEA). METHODS: The present study utilized a retrospective analysis of hospitalized patients who met the inclusion criteria for DFUs over a period of 7 years...

INTRODUCTION/PURPOSE: Ultrasound-guided popliteal fossa sciatic nerve (PFSN) blocks are performed with patients in the supine, lateral or prone position. No known studies compare the quality of images obtained from each approach. This study examines the quality of supine and prone PFSN ultrasound images. METHODS: Thirty-eight adult volunteers were sorted into two groups. Five regional anaesthesiologists performed ultrasound examinations of the PFSN on volunteers in supine and prone positions...

BACKGROUND: We aimed to assess the accuracy of artificial intelligence (AI) based real-time anatomy identification for ultrasound-guided peripheral nerve and plane block in eight regions in this prospective observational study. METHODS: After obtaining ethics committee approval and written informed consent from 40 healthy volunteers (20 men and 20 women, between 18 and 72 years old), an ultrasound device installed with AI software (Nerveblox, SmartAlfa, Turkey) were used to scan regions of the cervical plexus, brachial plexus, pectoralis (PECS), rectus sheet, femoralis, canalis adductorius, popliteal, and ESP by three anesthesiology trainees...

(1) Background: Remifentanil is used for intraoperative pain control; however, it has several side effects, such as hypotension and opioid-induced hyperalgesia. We aimed to determine whether an intraoperative remifentanil infusion may increase postoperative opioid consumption in patients undergoing total knee arthroscopy (TKA) under femoral nerve block (FNB) in addition to general anesthesia. (2) Methods: We randomly assigned 66 patients who underwent total knee arthroplasty to the remifentanil (R) and control (C) groups...

Background and objectives Ultrasound-guided femoral and popliteal sciatic nerve blocks are useful adjuncts for many below-knee procedures like debridement, amputation, etc. The objectives of the study were to find the efficacy and feasibility of the ultrasound-guided combined femoral and popliteal sciatic nerve block for below-knee procedures in the Emergency Medicine Department (ED). Methodology This prospective clinical study was carried out over three months in ED. A total of 30 patients undergoing below-knee procedures were included in the study...

OBJECTIVES: To evaluate the impact of the ultrasound-guided popliteal sciatic nerve block (PSNB) for pain management during endovascular treatment of chronic limb-threatening ischemia (CLTI). MATERIAL AND METHODS: From November 2020 to January 2022, 111 CLTI patients that underwent endovascular procedures were prospectively enrolled in this prospective single-arm interventional study. Ultrasound-guided PSNB was used for procedural pain control. Pain intensity was evaluated throughout the procedure (baseline, 10 min after the block, pain peak, and at the end of the procedure) with the visual analog scale (VAS)...

Inhibition of actin remodeling in nerves modulates action potential propagation and therefore could be used to treat acute pain. N-001 is a novel protein analgesic engineered from several C. Botulinum toxins. N-001 targets sensory neurons through ganglioside GT1b binding and ADP-ribosylates G-actin reducing actin remodeling. The activity and efficacy of N-001 was evaluated previously in vitro and in a mouse inflammatory pain model. To assess the relevance of N-001 for treatment of acute post-surgical pain, the current study evaluated the efficacy of N-001 in a mouse hind-paw incision model by peri-incisional and popliteal nerve block administration combined with mechanical testing...

BACKGROUND: We aim to share our popliteal sciatic nerve block (PSB) experience, which we applied to diabetic and nondiabetic patients in the operating room of our hospital. METHODS: The patients who underwent PSB for foot and ankle surgery between October 1, 2021, and December 31, 2021, in Sakarya University Training and Research Hospital were evaluated retrospectively. All nerve blocks were administered by a single anesthesiologist. Demographic data of the patients and the duration of the operation, the type of operation, the time of application of the nerve block, whether it was single or bifurcation block, and the onset times of motor and sensory block were also recorded in the perioperative period...

There are no established guidelines regarding anesthesia with a peripheral nerve block (PNB) in the young adult population with von Willebrand disease (vWD) type I. We present a case of a successful PNB outcome in a 20-year-old male patient with vWD type I, osteogenesis imperfecta (OI), and rheumatoid arthritis (RA) who underwent an intramedullary nailing surgery after suffering a left distal femur fracture secondary to a sports injury. Before the procedure, the patient was treated with HUMATE-P® [antihemophilic factor and von Willebrand factor (human)], ALPHANATE®  (antihemophilic factor/von Willebrand factor complex), and aminocaproic acid for hematologic control...

INTRODUCTION: Low and high volume mid-thigh (ie, distal femoral triangle) and distal adductor canal block approaches are frequently applied for knee surgical procedures. Although these techniques aim to contain the injectate within the adductor canal, spillage into the popliteal fossa has been reported. While in theory this could improve analgesia, it might also result in motor blockade due to coverage of motor branches of the sciatic nerve. This radiological cadaveric study, therefore, investigated the incidence of coverage of sciatic nerve divisions after various adductor canal block techniques...

PURPOSE: To evaluate the safety and effectiveness of ultrasound-guided popliteal sciatic nerve block (PSNB) for pain control in endovascular treatment of critical limb ischemia (CLI). MATERIALS AND METHODS: This retrospective study included 252 patients who underwent endovascular treatment for CLI between January 2020 and August 2022. Of these, 69 patients underwent PSNB, whereas moderate procedural sedation and analgesia was delivered in 183 patients. Pain scores were assessed using the visual analog scale (VAS) before and during the intervention...

The anesthetic technique for calcaneal surgery has been reported to include peripheral nerve blocks, such as a sciatic block in the popliteal fossa, followed by intraoperative sedation. Sciatic nerve blocks are associated with limb weakness and fall risk. We present a case of a patient presenting for outpatient calcaneal surgery. The anesthetic plan consisted of a proximal, ultrasound-guided, single-injection selective posterior tibial nerve block followed by intraoperative sedation. The nerve block was performed, surgery concluded, and the patient received six hours of postoperative analgesia...

BACKGROUND: The analgesic effectiveness of contemporary motor-sparing nerve blocks used in combination for analgesia in total knee arthroplasty is unclear. This network meta-analysis was conducted to evaluate the analgesic effectiveness of adding single-injection or continuous adductor canal block (ACB) with or without infiltration of the interspace between the popliteal artery and the capsule of the posterior knee (iPACK) to intraoperative local infiltration analgesia (LIA), compared to LIA alone, after total knee arthroplasty...

BACKGROUND: Major ankle and hindfoot surgery (e.g., ankle, triple and subtalar arthrodesis) typically causes severe postoperative pain, especially the first two postoperative days. Current modalities of postoperative analgesic treatment often include continuous peripheral nerve blocks of the saphenous and sciatic nerves via catheters in order to extend the duration of pain- and opioid-free nerve blockade to 48 h. Unfortunately, the 48 h-efficacy of continuous infusion via a catheter is reduced by a high displacement rate...

We report the case of a paediatric patient who presented at the Emergency Department with severe pain in the right lower extremity caused by a scorpion sting. Analgesics were ineffective, so we decided to perform an ultrasound-guided popliteal block, which provided complete analgesia and allowed the patient to be followed up in the outpatient department, with no adverse effects. The sting of the species of scorpion found in Spain is not dangerous to human life; however, it causes self-limiting localised pain that lasts for 24-48h, and can be severe...

BACKGROUND AND AIMS: Postoperative analgesia for Total Knee Arthroplasty (TKA) is paramount for early mobilisation and rehabilitation. The newer motor sparing peripheral nerve blocks for analgesia for TKA are 4 in 1 block, modified 4 in 1 block, infiltration between popliteal artery and capsule of the knee (IPACK) block along with adductor canal block (ACB). We hypothesised that Modified 4 in 1 block is as efficient as the already proven technique of combined IPACK and ACB in providing post-operative analgesia to the patients of TKA...
