INTRODUCTION: Sensory blockade of the brachial plexus with local anaesthetics for perioperative analgesia leads to stable haemodynamics intraoperatively, smoother emergence from general anaesthesia and decreased need for supplemental analgesics or suppositories in the Post-operative period. However, increasing the duration of local anaesthetic action is often desirable because it prolongs surgical anaesthesia and analgesia. Various studies in adults prove that steroids increase the duration of action of local anaesthetics when used as adjuncts...

BACKGROUND: This randomized double-blinded trial compared the effect of intravenous and perineural dexamethasone (8 mg) on the duration of motor block for ultrasound (US)-guided axillary brachial plexus block (AXB). METHODS: Patients undergoing upper limb surgery with US-guided AXB were randomly allocated to receive preservative-free dexamethasone (8 mg) via intravenous (n = 75) or perineural (n = 75) administration. The local anesthetic agent, 1% lidocaine -0...

BACKGROUND AND OBJECTIVES: A chemically compatible, safe 4-drug multimodal formulation of bupivacaine combined with 3 adjuvants (clonidine, buprenorphine, and dexamethasone) has been proposed for long-lasting single-injection peripheral nerve blocks in patients. However, the relative importance of each of the adjuvants of the 4-drug formulation in producing long-lasting nerve blocks has not been determined. The aim of this study in rats was to determine which adjuvants (clonidine, buprenorphine, or dexamethasone) are essential for producing a long-lasting nerve block...

PURPOSE: To determine systemic absorption of dexamethasone by detection of plasma concentration using high performance liquid chromatography following its administration along with local anesthetic agent as a mixture via pterygomandibular space. METHODS: A prospective randomized double-blind clinical study was undertaken to analyze the plasma concentration of dexamethasone after intra-space pterygomandibular injection along with local anesthesia. The study was performed as per split mouth model where the mandibular quadrant allocation was done on a random basis considering each of the 30 patients is included in the two study interventions (SS and CS)...

BACKGROUND: We examined the effect of the addition of dexamethasone to bupivacaine for femoral nerve blocks on the block duration and the quality of post-operative analgesia following total knee replacement surgery. METHODS: In total, 200 ASA I-III patients were randomly allocated to either the control group who received bupivacaine 0.5% or the dexamethasone group who received bupivacaine 0.5% plus 8 mg dexamethasone for the femoral nerve block, followed by a continuous perineural bupivacaine infusion started at the time of block resolution...

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...

BACKGROUND: The role of dexamethasone as an adjunct in peripheral nerve blockades is still unclear. OBJECTIVES: This article reviews the actual knowledge and scientific evidence for dexamethasone as an adjunct in peripheral regional anesthesia. Moreover, it discusses the benefits of the systemic versus the perineural mode of application. RESULTS: Dexamethasone prolongs sensible as well as motor blockades in peripheral nerve blocks when applied intravenously or perineurally...

BACKGROUND: The purpose of this study was to evaluate the effect of dexamethasone or dexmedetomidine added to ropivacaine on the onset and duration of ultrasound-guided axillary brachial plexus blocks (BPB). METHODS: Fifty-one ASA physical status I-II patients with elective forearm and hand surgery under axillary brachial plexus blocks were randomly allocated to receive 20 ml of 0.5% ropivacaine with 2 ml of isotonic saline (C group, n = 17), 20 ml of 0.5% ropivacaine with 2 ml (10 mg) of dexamethasone (D group, n = 17) or 20 ml of 0...

BACKGROUND: The use of peripheral nerve blocks for anesthesia and postoperative analgesia has increased significantly in recent years. Adjuvants are frequently added to local anesthetics to prolong analgesia following peripheral nerve blockade. Numerous randomized controlled trials and meta-analyses have examined the pros and cons of the use of various individual adjuvants. OBJECTIVES: To systematically review adjuvant-related randomized controlled trials and meta-analyses and provide clinical recommendations for the use of adjuvants in peripheral nerve blocks...

PURPOSE OF REVIEW: This review outlines the analgesic role of perineural adjuvants for local anesthetic nerve block injections, and evaluates current knowledge regarding whether adjuvants modulate the neurocytologic properties of local anesthetics. RECENT FINDINGS: Perineural adjuvant medications such as dexmedetomidine, clonidine, buprenorphine, dexamethasone, and midazolam play unique analgesic roles. The dosing of these medications to prevent neurotoxicity is characterized in various cellular and in-vivo models...

BACKGROUND AND OBJECTIVES: Sciatic nerve block provides analgesia after foot and ankle surgery, but block duration may be insufficient. We hypothesized that perineural dexamethasone and buprenorphine would reduce pain scores at 24 hours. METHODS: Ninety patients received ultrasound-guided sciatic (25 mL 0.25% bupivacaine) and adductor canal (10 mL 0.25% bupivacaine) blockade, with random assignment into 3 groups (30 patients per group): control blocks + intravenous (IV) dexamethasone (4 mg) (control); control blocks + IV buprenorphine (150 μg) + IV dexamethasone (IV buprenorphine); and nerve blocks containing buprenorphine + dexamethasone (perineural)...

BACKGROUND: Dexamethasone has been studied as an effective adjuvant to prolong the analgesia duration of local anesthetics in peripheral nerve block. However, the route of action for dexamethasone and its potential neurotoxicity are still unclear. METHODS: A mouse sciatic nerve block model was used. The sciatic nerve was injected with 60ul of combinations of various medications, including dexamethasone and/or bupivacaine. Neurobehavioral changes were observed for 2 days prior to injection, and then continuously for up to 7 days after injection...

BACKGROUND: Dexamethasone decreases postoperative pain and prolongs the duration of local anaesthetic peripheral nerve blocks in studies including a limited number of patients. OBJECTIVE: The objective of this study is to evaluate the effect of combining dexamethasone with local anaesthetic on sensory and motor peripheral nerve blockade in adults. DESIGN: A systematic review with meta-analysis of randomised controlled trials. DATA SOURCES: We systematically searched in Medline, Embase, Google Scholar and Cochrane Controlled Trials Register up to December 2013...

BACKGROUND: Several studies have presented evidence that blocking peripheral nerves is effective for the treatment of some headaches and cranial neuralgias, resulting in reduction of the frequency, intensity, and duration of pain. OBJECTIVES: In this article we describe the role of nerve block in the treatment of headaches and cranial neuralgias, and the experience of a tertiary headache center regarding this issue. We also report the anatomical landmarks, techniques, materials used, contraindications, and side effects of peripheral nerve block, as well as the mechanisms of action of lidocaine and dexamethasone...

BACKGROUND: Dexamethasone prolongs the duration of single-shot interscalene brachial plexus block (SISB). However, dose-dependency of dexamethasone as an adjuvant for SISB remains insufficiently understood. OBJECTIVE: The objective of this study is to evaluate the effect of different doses of dexamethasone on the duration of SISB using ropivacaine 0.5%. DESIGN: A randomised, double-blind controlled trial. SETTING: Single university tertiary care centre...

BACKGROUND: The aim of this study was to evaluate the efficacy of single thoracic paravertebral injection in acute thoracic herpes zoster (HZ) pain, eruptive duration, and the incidence of postherpetic neuralgia (PHN). METHODS: One hundred thirty-eight patients over 50 years of age with acute thoracic herpetic eruption were randomly assigned to receive a paravertebral block using either 10 mL saline (placebo group) or 25 mg bupivacaine, plus 8 mg dexamethasone in a total volume of 10 mL (active group)...
