Comparative evaluation of monopolar and bipolar radiofrequency ablation of genicular nerves in chronic knee pain due to osteoarthritis.

Indian J Anaesth 2018 Nov;62(11):876-880

Department of Anesthesia and Pain Relief Services, Tata Motors Hospital, Jamshedpur, Jharkhand, India.

Background And Aims: Monopolar radiofrequency ablation (MRFA) of the genicular nerve is effective in managing chronic knee pain from osteoarthritis (OA); however, the procedure itself is associated with significant pain due to manipulation of electrode to localise tiny genicular nerves. We hypothesised that inserting two electrodes to target the genicular nerves [bipolar radiofrequency ablation (BRFA)] without sensory localisation can decrease the procedural pain with equal analgesic efficacy in treating knee pain.

Methods: Thirty patients with chronic knee pain due to OA were randomised to receive either MRFA ( = 15) or BRFA ( = 15), after having 50% pain relief with diagnostic genicular nerve block. Read More

Effect of high-frequency alternating current transcutaneous stimulation over muscle strength: a controlled pilot study.

J Neuroeng Rehabil 2018 Nov 12;15(1):103. Epub 2018 Nov 12.

Toledo Physiotherapy Research Group (GIFTO), Nursing and Physiotherapy School, Castilla La Mancha University, 45071, Toledo, Spain.

Background: High-frequency alternating currents of greater than 1 kHz applied on peripheral nerves has been used in animal studies to produce a motor nerve block. It has been evidenced that frequencies higher than 5 kHz are necessary to produce a complete peripheral nerve block in primates, whose nerve thickness is more similar to humans. The aim of the study was to determine the effect on muscle strength after the application of a high-frequency stimulation at 5 and 10 kHz compared to sham stimulation in healthy volunteers.

Opioid-Sparing Analgesia and Enhanced Recovery After Total Knee Arthroplasty Using Combined Triple Nerve Blocks With Local Infiltration Analgesia.

J Arthroplasty 2018 Oct 13. Epub 2018 Oct 13.

Department of Orthopaedics, Faculty of Medicine, King Chulalongkorn Memorial Hospital, Chulalongkorn University, Bangkok, Thailand.

Background: Peripheral nerve block and local infiltration analgesia (LIA) have an increasing role as part of multimodal analgesia for enhanced recovery after total knee arthroplasty (TKA). We hypothesized that the combination of obturator nerve block (ONB) and tibial nerve block (TNB) would reduce pain and opioid consumption more than ONB or TNB alone when combined with continuous adductor canal block and LIA.

Methods: Ninety patients were recruited into the study and received spinal anesthesia, LIA, and continuous adductor canal block. Read More

Proc Natl Acad Sci U S A 2018 11 22;115(45):E10720-E10729. Epub 2018 Oct 22.

Graduate Institute of Acupuncture Science, China Medical University, Taichung, Taiwan 40402;

Adequate pain management remains an unmet medical need. We previously revealed an opioid-independent analgesic mechanism mediated by orexin 1 receptor (OX1R)-initiated 2-arachidonoylglycerol (2-AG) signaling in the ventrolateral periaqueductal gray (vlPAG). Here, we found that low-frequency median nerve stimulation (MNS) through acupuncture needles at the PC6 (Neiguan) acupoint (MNS-PC6) induced an antinociceptive effect that engaged this mechanism.

Selective Decrease in Allodynia With High-Frequency Neuromodulation via High-Electrode-Count Intrafascicular Peripheral Nerve Interface After Brachial Plexus Injury.

Neuromodulation 2018 Aug 17. Epub 2018 Aug 17.

Department of Bioengineering, University of Utah, Salt Lake City, UT, USA.

Objectives: Kilohertz high-frequency alternating current (KHFAC) electrical nerve stimulation produces a reversible nerve block in peripheral nerves in human patients with chronic pain pathologies. Although this stimulation methodology has been verified with nonselective extrafascicular electrodes, the effectiveness of producing a selective nerve block with more-selective intrafascicular electrodes has not been well documented. The objective of this study was to examine whether intrafascicular electrodes can block painful stimuli while preserving conduction of other neural activity within the implanted nerve. Read More

Continuous Popliteal-Sciatic Blocks for Postoperative Analgesia: Traditional Proximal Catheter Insertion Superficial to the Paraneural Sheath Versus a New Distal Insertion Site Deep to the Paraneural Sheath.

Anesth Analg 2018 Aug 9. Epub 2018 Aug 9.

From the Department of Anesthesiology, University of California, San Diego, California.

We tested the hypothesis that during a continuous popliteal-sciatic nerve block, postoperative analgesia is improved with the catheter insertion point "deep" to the paraneural sheath immediately distal to the bifurcation between the tibial and common peroneal branches, compared with the traditional approach "superficial" to the paraneural sheath proximal to the bifurcation. The needle tip location was determined to be accurately located with a fluid bolus visualized with ultrasound; however, catheters were subsequently inserted without a similar fluid injection and visualization protocol (visualized air injection was permitted and usually implemented, but not required per protocol). The average pain (0-10 scale) the morning after surgery for subjects with a catheter inserted at the proximal subparaneural location (n = 31) was a median (interquartile) of 1. Read More

Discriminative sensory characteristics of the lateral femoral cutaneous nerve after mepivacaine-induced block.

Scand J Pain 2013 Apr 1;4(2):95-100. Epub 2013 Apr 1.

Department of Anaesthesiology and Surgical Intensive Care Medicine, University Medical Center Mannheim, Medical Faculty Mannheim Heidelberg University, Mannheim, Germany.

Background and objectives Unmyelinated C-fibres comprise the largest group of somatic afferents and have demonstrated a crucial role not only in the perception of high-threshold mechanically, thermally or chemically induced pain, but also in non-harmful low-threshold mechanical stimuli [1,2]. The objective of our study was to characterize differential sensitivity changes of C-fibre related subclasses of high-threshold and low-threshold polymodal nociceptors and low-threshold mechanoreceptors to the local anaesthetic (LA) mepivacaine during nerve block of the purely sensory lateral femoral cutaneous nerve (LFCN) in human. We assumed a diverse response of different classes of afferents to the two different concentrations of the LA mepivacaine (Scandicaine). Read More

A randomized study comparing plasma concentration of ropivacaine after local infiltration analgesia and femoral block in primary total knee arthroplasty.

Scand J Pain 2012 Jan 1;3(1):46-51. Epub 2012 Jan 1.

Department of Anaesthesiology and Intensive Care, Karolinska Institutet and Karolinska University Hospital, Solna, Sweden.

Pain after total knee arthroplasty (TKA) is difficult to control. A recently developed and increasingly popular method for postoperative analgesia following knee and hip arthroplasty is Local Infiltration Analgesia (LIA) with ropivacaine, ketorolac and epinephrine. This method is considered to have certain advantages, which include administration at the site of traumatized tissue, minimal systemic side effects, faster postoperative mobilization, earlier postoperative discharge from hospital and less opioid consumption.

Response to Cervical Medial Branch Blocks In Patients with Cervicogenic Vertigo.

Pain Physician 2018 05;21(3):285-294

Department of Neurosurgery, University of Ulm, Ulm, Germany; Department of Neurosurgery, Nova Clinic Biberach, Biberach, Germany.

Background: Among the various causes of vertigo, the so-called cervicogenic vertigo (CV) has been the most controversial. However, perturbations of proprioceptive signals and abnormal activity of the cervical afferents can induce vertigo. Medial branch blocks (MBBs) are a diagnostic tool designed to test whether a patient's neck pain is mediated by one or more of the medial branches of the dorsal rami of the spinal nerve. Read More
