Rebound pain following peripheral nerve block anaesthesia in acute ankle fracture surgery: An exploratory pilot study.

Acta Anaesthesiol Scand 2018 Nov 8. Epub 2018 Nov 8.

Department of Anaesthesiology, Herlev and Gentofte University Hospital, Herlev, Denmark.

Background: Peripheral nerve blocks (PNB) are increasingly used for anaesthesia and postoperative pain control in acute orthopaedic limb surgery but rebound pain upon cessation of PNBs may challenge the benefits on the pain profile. We aimed to explore the pain profile following acute ankle fracture surgery under PNB anaesthesia and investigate if rebound pain could pose a clinical problem.

Methods: Exploratory, observational study of adults scheduled for acute primary internal fixation of an ankle fracture under ultrasound-guided popliteal sciatic and saphenous ropivacaine block anaesthesia. Read More

The Importance of the Saphenous Nerve Block for Analgesia Following Major Ankle Surgery: A Randomized, Controlled, Double-Blind Study.

Reg Anesth Pain Med 2018 Jul;43(5):474-479

Department of Anesthesiology and Intensive Care Medicine, Kolding Hospital, Kolding, Denmark.

Background And Objectives: Major ankle surgery causes intense postoperative pain, and whereas the importance of a sciatic nerve block is well established, the clinical significance of a supplemental saphenous nerve block has never been determined in a prospective, randomized, double-blind, placebo-controlled trial. We hypothesized that a saphenous nerve block reduces the proportion of patients experiencing significant clinical pain after major ankle surgery.

Methods: Eighteen patients were enrolled and received a popliteal sciatic nerve block. Read More

Saphenous Nerve Block From Within the Knee Is Feasible for TKA: MRI and Cadaveric Study.

Clin Orthop Relat Res 2018 Jan;476(1):30-36

J. J. Kavolus, D. E. Attarian, P. F. Lachiewicz Department of Orthopaedic Surgery, Duke University Medical Center, Durham, NC, USA D. Sia, H. G. Potter, Department of Radiology and Imaging, MRI Research, Hospital for Special Surgery, New York, NY, USA.

Background: Surgeon-performed periarticular injections and anesthesiologist-performed femoral nerve or adductor canal blocks with local anesthetic are in common use as part of multimodal pain management regimens for patients undergoing TKA. However, femoral nerve blocks risk causing quadriceps weakness and falls, and anesthesiologist-performed adductor canal blocks are costly in time and resources and may be unreliable. We investigated the feasibility of a surgeon-performed saphenous nerve ("adductor canal") block from within the knee at the time of TKA. Read More

Femoral Nerve Block versus Adductor Canal Block for Analgesia after Total Knee Arthroplasty.

Knee Surg Relat Res 2017 Jun;29(2):87-95

Department of Orthopaedic Surgery, Seoul St. Mary's Hospital, Seoul, Korea.

Inadequate pain management after total knee arthroplasty (TKA) impedes recovery, increases the risk of postoperative complications, and results in patient dissatisfaction. Although the preemptive use of multimodal measures is currently considered the principle of pain management after TKA, no gold standard pain management protocol has been established. Peripheral nerve blocks have been used as part of a contemporary multimodal approach to pain control after TKA. Read More

Department of Anaesthesiology, First Affiliated Hospital, Wenzhou Medical University, Zhejiang, China. Electronic address:

Purpose: A literature review of multiple clinical studies on mixing additives to improve pharmacologic limitation of local anesthetics during peripheral nerve blockade revealed inconsistency in success rates and various adverse effects. Animal research on dexmedetomidine as an adjuvant on the other hand has promising results, with evidence of minimum unwanted results. This randomized, double-blinded, contrastable observational study examined the efficacy of adding dexmedetomidine to a mixture of lidocaine plus ropivacaine during popliteal sciatic nerve blockade (PSNB).

Effect of Nerve Stimulation Use on the Success Rate of Ultrasound-Guided Subsartorial Saphenous Nerve Block: A Randomized Controlled Trial.

Reg Anesth Pain Med 2017 Jan/Feb;42(1):25-31

From the Department of Anesthesia, Division of Regional Anesthesia, St. Paul's Hospital; and Department of Anesthesiology, Pharmacology & Therapeutics, The University of British Columbia, Vancouver, British Columbia, Canada.

Background And Objectives: Ultrasound-guided subsartorial saphenous nerve block is commonly used to provide complete surgical anesthesia of the foot and ankle in combination with a popliteal sciatic nerve block. However, in part owing to its small caliber and absence of a prominent vascular landmark in the subsartorial plane distal to the adductor canal, the saphenous nerve is more difficult to reliably block than the sciatic nerve in the popliteal fossa. Although the saphenous nerve is a sensory nerve only, neurostimulation can be used to elicit a "tapping" sensation on the anteromedial aspect of the lower leg extending toward the medial malleolus.

Growth hormone regulates the sensitization of developing peripheral nociceptors during cutaneous inflammation.

Pain 2017 02;158(2):333-346

aDepartment of Anesthesia, Division of Pain Management, Cincinnati Children's Hospital Medical Center, Cincinnati, OH, USA bDr. Liu is now with the Shaanxi University of Chinese Medicine, Xi'an, China cDepartment of Pediatrics, University of Cincinnati, Cincinnati, OH, USA.

Cutaneous inflammation alters the function of primary afferents and gene expression in the affected dorsal root ganglia (DRG). However, specific mechanisms of injury-induced peripheral afferent sensitization and behavioral hypersensitivity during development are not fully understood. Recent studies in children suggest a potential role for growth hormone (GH) in pain modulation. Read More

Does dexamethasone have a perineural mechanism of action? A paired, blinded, randomized, controlled study in healthy volunteers.

Br J Anaesth 2016 Nov;117(5):635-641

Department of Anaesthesia, Bispebjerg and Frederiksberg Hospitals, University of Copenhagen, Copenhagen, Denmark.

Background: Dexamethasone prolongs block duration. Whether this is achieved via a peripheral or a central mechanism of action is unknown. We hypothesized that perineural dexamethasone added as an adjuvant to ropivacaine prolongs block duration compared with ropivacaine alone, by a locally mediated effect when controlled for a systemic action.

Anesthesia and analgesia methods for outpatient anterior cruciate ligament reconstruction.

Orthop Traumatol Surg Res 2016 12 26;102(8S):S251-S255. Epub 2016 Sep 26.

Hopital universitaire de la croix-rousse, Centre Albert-Trillat, 103, grande rue de la Croix-Rousse, 69004 Lyon, France.

Introduction: More and more anterior cruciate ligament (ACL) reconstructions are being performed as outpatient surgery in France, because of economic considerations. Postoperative pain is the most common reason for delayed discharge that could require hospitalization, and the main reason for unanticipated hospital admission. The purpose of this study was to define the best anesthesia and analgesia methods for ACL reconstruction. Read More

Perineural dexamethasone with subsartorial saphenous nerve blocks in ACL reconstruction.

Knee Surg Sports Traumatol Arthrosc 2017 Apr 13;25(4):1298-1306. Epub 2016 Apr 13.

Department of Anesthesiology, Hospital for Special Surgery, New York, NY, USA.

Purpose: Subsartorial saphenous nerve blockade (SSNB) is an effective analgesic alternative to femoral nerve blockade after anterior cruciate ligament (ACL) reconstruction with bone-tendon-bone (BTB) autograft. It was hypothesized that dexamethasone in a SSNB will prolong analgesia, improve pain and satisfaction, and reduce postoperative opioid requirements and side effects.

Methods: One hundred ninety-five patients undergoing ACL reconstruction with BTB autograft (ages 16-65) were enrolled. Read More

Background: Adductor canal block (ACB) has emerged as an appealing alternative to femoral nerve block (FNB) that produces a predominantly sensory nerve block by anesthetizing the saphenous nerve. Studies have shown greater quadriceps strength preservation with ACB compared with FNB, but no advantage has yet been shown in terms of fall risk. The Tinetti scale is used by physical therapists to assess gait and balance, and total score can estimate a patient's fall risk. Read More
