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

A new method of administering local anesthesia for calf disbudding: Findings from a comparative on-farm study in New Zealand.

J Dairy Sci 2019 Mar 11;102(3):2492-2506. Epub 2019 Jan 11.

Vetlife Temuka, Temuka 7920, New Zealand.

Anesthesia of the horn bud for calf disbudding commonly is attained by injection of local anesthetic over branches of the cornual nerve, with anesthesia achieved in 3 to 20 min. With experienced and trained staff, this method is effective in 88 to 100% of calves. Variability in response and time of onset can compromise calf welfare if calves are disbudded before anesthesia is attained. 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 Dec 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 Feb 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.

Landmark Technique for a Wrist Block.

JBJS Essent Surg Tech 2018 Mar 14;8(1):e7. Epub 2018 Mar 14.

Sheffield Teaching Hospitals, Sheffield, United Kingdom.

Effective anesthesia of the hand and wrist has many uses inside and outside the operating room. In the emergency department or fracture clinic, a wrist block may be used for closed reductions of dislocations and fractures or for effective inspection and treatment of wounds. In the operating room, surgery may be carried out under a wrist block alone or a wrist block may be used as an adjunct to general anesthesia as the block is an opiate-sparing option to facilitate outpatient surgery and to provide many hours of postoperative analgesia, particularly if administered prior to the commencement of surgery.

Short-term Outcomes in Pediatric Patients Managed with Peripheral Nerve Blockade for Arthroscopic Anterior Cruciate Ligament Reconstruction and/or Meniscus Surgeries.

Cureus 2018 Jun 21;10(6):e2852. Epub 2018 Jun 21.

Orthopaedics, The Children's Hospital of Philadelphia, Philadelphia, USA.

Introduction Peripheral nerve blockade (PNB) can be a useful component of a multimodal analgesia approach in managing pain after knee arthroscopy. However, the impact of PNB and short-term recovery in pediatric patients, particularly adolescents, who underwent knee arthroscopy for anterior cruciate ligament (ACL) reconstruction and/or meniscus surgery (repair or resection) has not been well characterized. This prospective study presents observational data on short-term patient outcomes and side effects for 72 hours following discharging home of pediatric patients who underwent arthroscopic ACL and/or meniscus procedures with PNB.

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
