An Objective Assessment of the Effect of Anesthetizing the Median Nerve on Lameness Caused by Pain in the Cubital Joint.

J Equine Vet Sci 2019 Apr 19;75:9-13. Epub 2018 Dec 19.

Department of Clinical Sciences, Auburn University College of Veterinary Medicine, Auburn, AL.

The median nerve, along with the ulnar nerve, is often anesthetized when performing a lameness examination in horses. Because of the close proximity of the median nerve to the cubital joint, proximal migration of local anesthetic might ameliorate pain originating from the cubital joint. The objective of this study was to determine if a median nerve block will ameliorate lameness caused by pain in the cubital joint. Read More

Dose-response relationship of perineural dexamethasone for interscalene brachial plexus block: a randomised, controlled, triple-blind trial.

Anaesthesia 2019 Apr 11. Epub 2019 Apr 11.

Department of Anaesthesia, AZ Groeninge, Kortrijk, Belgium.

Perineural dexamethasone has a ceiling dose of 4 mg for prolongation of analgesia duration after injection of long-acting local anaesthetic for peripheral nerve block, but evidence for doses < 4 mg is lacking. This randomised controlled triple-blind trial tested the hypothesis that increasing doses of perineural dexamethasone between 1 mg and 4 mg would prolong the duration of analgesia in a dose-dependent manner. Eighty ASA physical status 1-2 patients scheduled for shoulder arthroscopy under general anaesthesia with ultrasound-guided interscalene brachial plexus block were randomly allocated to receive saline (control), dexamethasone 1 mg, 2 mg, 3 mg and 4 mg, together with 20 ml ropivacaine 0.

Non-intubated thoracoscopic surgery for lung cancer in patients with impaired pulmonary function.

Ann Transl Med 2019 Feb;7(3):40

Division of Thoracic Surgery, Department of Surgery, National Taiwan University Hospital and National Taiwan University College of Medicine, Taipei, Taiwan.

Background: Patients with impaired lung function or chronic obstructive pulmonary disease (COPD) are considered high-risk for intubated general anesthesia, which may preclude them from surgical treatment of their lung cancers. We evaluated the feasibility of non-intubated video-assisted thoracoscopic surgery (VATS) for the surgical management of lung cancer in patients with impaired pulmonary function.

Methods: From August 2009 to June 2015, 28 patients with impaired lung function (preoperative forced expiratory volume in 1 second <70% of the predicted value) underwent non-intubated VATS using a combination of thoracic epidural anesthesia or intercostal nerve block, and intra-thoracic vagal block with target-controlled sedation.

Clin Orthop Relat Res 2019 Mar;477(3):622-632

J. T. YaDeau, S. S. Liu, M. A. Gordon, E. A. Goytizolo, Y. Lin, A. A. Schweitzer, Department of Anesthesiology, Critical Care and Pain Management Hospital for Special Surgery, New York, NY, USA D. M. Dines, L. V. Gulotta, Department of Orthopedic Surgery, Sports Medicine, Hospital for Special Surgery, New York, NY, USA K. G. Fields, Healthcare Research Institute, Hospital for Special Surgery, New York, NY, USA.

Background: The pain experience for total shoulder arthroplasty (TSA) patients in the first 2 weeks after surgery has not been well described. Many approaches to pain management have been used, with none emerging as clearly superior; it is important that any approach minimizes postoperative opioid use.

Questions/purposes: (1) With a long-acting nerve block and comprehensive multimodal analgesia, what are the pain levels after TSA from day of surgery until postoperative day (POD) 14? (2) How many opioids do TSA patients take from the day of surgery until POD 14? (3) What are the PainOUT responses at POD 1 and POD 14, focusing on side effects from opioids usage?

Methods: From January 27, 2017 to December 6, 2017, 154 TSA patients were identified as potentially eligible for this prospective, institutional review board-approved observational study. Read More

Ultrasound-guided continuous femoral nerve block: a randomized trial on the influence of femoral nerve catheter orifice configuration (six-hole versus end-hole) on post-operative analgesia after total knee arthroplasty.

BMC Anesthesiol 2018 12 19;18(1):191. Epub 2018 Dec 19.

Department of Anesthesiology, University Hospitals of Geneva, Rue Gabrielle-Perret-Gentil 4, CH-1211, Geneva 14, Switzerland.

Background: Multiorifice catheters have been shown to provide superior analgesia and significantly reduce local anesthetic consumption compared with end-hole catheters in epidural studies. This prospective, blinded, randomized study tested the hypothesis that, in continuous femoral nerve block (CFNB) under ultrasound guidance, multiorifice catheter would reduce local anesthetic consumption at 24 h compared with end-hole catheter.

Methods: Eighty adult patients (aged ≥18 years) scheduled to undergo primary total knee arthroplasty under a combination of CFNB, sciatic nerve block and general anesthesia were randomized to CFNB using either a 3-pair micro-hole (Contiplex, BRAUN®, 20G - 400 mm) or an end-hole (Silverstim VYGON®, 20G - 500 mm) catheter.

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 2019 02 13;34(2):295-302. 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

Median nerve stimulation induces analgesia via orexin-initiated endocannabinoid disinhibition in the periaqueductal gray.

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.
