dexamethasone AND peripheral nerve block

Introduction Currently, peripheral nerve block has shown immense potential with effective patient satisfaction. In the event of upper limb surgeries, the supraclavicular brachial plexus approach under ultrasound guidance renders quick and dense anesthesia. In addition, the clinical utility of adjuvants with local anesthetics elicits a good quality of nerve block with improved duration and inset. So the aim of the present study was to compare the block characteristics of dexmedetomidine and dexamethasone during supraclavicular brachial plexus block in patients undergoing upper limb surgeries...

Chat Generative Pre-trained Transformer (ChatGPT), an artificial intelligence chatbot, produces detailed responses and human-like coherent answers, and has been used in the clinical and academic medicine. To evaluate its accuracy in regional anesthesia topics, we produced a ChatGPT review on the addition of dexamethasone to prolong peripheral nerve blocks. A group of experts in regional anesthesia and pain medicine were invited to help shape the topic to be studied, refine the questions entered in to the ChatGPT program, vet the manuscript for accuracy, and create a commentary on the article...

OBJECTIVES: Headache after aneurysmal subarachnoid hemorrhage (HASH) is common, severe, and often refractory to conventional treatments. Current treatment standards include medications including opioids, until the pain is mitigated. Peripheral nerve blocks (PNBs) may be an effective therapeutic option for HASH. We conducted a small before-and-after study of PNBs to determine safety, feasibility, and efficacy in treatment of HASH. METHODS: We conducted a pilot before-and-after observational study and collected data for 5 patients in a retrospective control group and 5 patients in a prospective intervention PNB group over a 12-month period...

Introduction Acute pain following laparoscopic surgeries interferes with the rehabilitation of the patient. Knowledge about the pain pathway from a particular area helps in blocking pain transmission at different sites. Ultrasonography (USG)-guided peripheral nerve blocks help in controlling pain better than non-steroidal anti-inflammatory drugs (NSAIDS) and opioids since they directly act by interrupting the pain pathway and interfere less with the physiology of the body. This study was planned with the objectives to evaluate the analgesic efficacy of USG-guided erector spinae plane block (ESPB) and oblique subcostal transversus abdominis plane (OSTAP) block in patients undergoing elective laparoscopic cholecystectomy, to compare the analgesic requirements in both groups, and to compare the VAS scores in both groups...

BACKGROUND: Intravenous dexamethasone prolongs duration of analgesia or sensory block after injection of local anaesthetics close to peripheral nerves by an average of 8 h. Uncertainty remains on the potential increase in the duration of sensory block after spinal anaesthesia. The objective of this randomised controlled double-blinded trial was to investigate whether dexamethasone i.v. prolongs the sensory block of spinal anaesthesia with bupivacaine when compared with a control group...

OBJECTIVES: Patients undergoing total knee arthroplasty (TKA) may experience moderate-to-severe subacute pain after hospital discharge that may be undermanaged. We aimed to evaluate the effect of methylprednisolone added to ultrasound-guided peripheral nerve blocks (PNBs) combined with multimodal analgesia including intravenous dexamethasone for prolonged analgesia after early discharge. MATERIALS AND METHODS: We randomized 80 patients who underwent fast-track TKA into 2 groups...

PURPOSE: Glucocorticoids are commonly used as regional anesthesia adjuvants to improve blockade quality and duration. There are limited data in the literature regarding the potential systemic effects and safety of perineural glucocorticoids. This study examines the effects of perineural glucocorticoids on serum glucose, potassium, and white blood cell count (WBC) in the immediate postoperative period after primary total hip arthroplasty (THA). PATIENTS AND METHODS: A retrospective cohort study was carried out at a tertiary academic medical center utilizing electronic health records of 210 patients who underwent THA, for which patients received either a periarticular local anesthetic injection alone (PAI, N=132) or additional peripheral nerve blocks (PNB, N=78) containing 10 mg dexamethasone and 80 mg methylprednisolone acetate (PAI+PNB)...

The combination of drugs and routes of administration produces a synergistic effect, and one of the most important components of multimodal analgesic strategies are, therefore, nerve blocks for pain management. The effect of a local anaesthetic can be prolonged by administering an adjuvant. In this systematic review, we included studies on adjuvants associated with local anaesthetics in peripheral nerve blocks published in the last 5 years in order to evaluate their effectiveness. The results were reported according to the PRISMA guidelines...

BACKGROUND: Although intravenous dexamethasone prolongs the duration of analgesia for peripheral nerve blocks (PNB), the optimal dose of dexamethasone is not yet determined. This protocol aims to compare the analgesic effects of different doses of intravenous dexamethasone on PNB. METHODS: We will search PubMed, EMBASE, the Cochrane Central register of Controlled Trials (CENTRAL), and Web of Science to identify randomized controlled trials that compared the effects of different doses of intravenous dexamethasone for PNB...

BACKGROUND: Rebound pain is extreme pain that persists after the effects of regional anesthesia wear off. Rebound pain occurrence and intensity are influenced by patient, surgical, and anesthesia-related factors. The incidence and severity of rebound pain after peripheral nerve block resolution are both reduced by the use of perioperative multimodal strategy. The purpose of the current paper was to evaluate the frequency, seriousness, and risk factors for rebound pain following peripheral nerve block resolution...

Prolongation of peripheral nerve blockade by intravenous dexamethasone may be extended by intravenous dexmedetomidine. We randomly allocated 122 participants who had intravenous dexamethasone 0.15 mg.kg-1 before interscalene brachial plexus block for day-case arthroscopic rotator cuff repair to intravenous saline (62 participants) or intravenous dexmedetomidine 1 μg.kg-1 (60 participants). The primary outcome was time from block to first oral morphine intake during the first 48 postoperative hours...

Rebound pain is a severe post-surgical pain which occurs after the resolution of peripheral nerve blocks. Current literature suggests that rebound pain affects around 50% of those receiving a peripheral nerve block. Possible interventions constitute patient education, bridging analgesia from the resolution of the nerve block, multimodal analgesic regimes, block adjuvants, or continuous pain catheters. Factors such as low age, female gender, bone surgery, and absence of IV dexamethasone are likely to be associated with rebound pain, as argued in this review...

PURPOSE OF REVIEW: The duration of single-injection regional anaesthesia is limited due to the inherent pharmacological properties of local anaesthetics. The ideal duration of a regional anaesthesia block lasting for the first 24 h postoperatively can be stated, while a residual analgesic effect thereafter is desirable.The aim of this review is to present current options to prolong the duration of action of single-injection peripheral regional anaesthesia in the ambulatory setting...

Recently, peripheral nerve blocks are extensively applied for many patients undergoing surgical or nonsurgical analgesia. However, the effectiveness is limited by the duration of action of local anesthetics. Therefore, the application of adding local anesthetic adjuvants is evolved to prolong the duration of analgesia and decrease the concentration of local anesthetics in peripheral nerve blocks. There are many local anesthetic adjuvants available such as morphine, fentanyl, sufentanil, hydromorphone, and buprenorphine, dexmedetomidine, dexamethasone, midazolam, and magnesium sulfate...

We studied the interaction between glucocorticoid receptor (GR) and HCN4 channels in the rat model of spared nerve injury (SNI) in Sprague-Dawley rats (n=124). The animals were randomly divided into 6 groups: sham-operated (SO; n=24), SNI (reference group; n=20), and 4 experimental SNI groups intrathecally treated with dexamethasone (DEX; GR agonist; n=20), RU38486 (GR antagonist; n=20), ZD7288 (HCN channels blocker; n=20), and ZD7288+DEX (n=20). The paw mechanical withdrawal threshold (PWT) was measured one day before surgery (SO group) and on days 1, 3, 7, 14, and 21 after surgery...

PURPOSE: Opioid consumption after total knee arthroplasty (TKA) remains a challenge with single injection nerve blocks even with common local anesthetic adjuvants dexamethasone (DEX). This study aimed to investigate the effects of adding methylprednisolone acetate (MPA) to adductor canal blocks (ACB) and interspace between the popliteal artery and capsule of the posterior knee (iPACK) blocks on postoperative opioid consumption. METHODS: A retrospective analysis was conducted on 100 consecutive TKA patients equally assigned into two groups, with one group receiving DEX through ACB and iPACK block and the other group receiving DEX and methylprednisolone acetate (DEX/MPA) through the same nerve blocks...

PURPOSE: Thoracic paravertebral block (TPVB) is a recommended regional analgesia during video-assisted thoracoscopic surgery (VATS). However, single-injection TPVB does not last long enough to provide sufficient acute postoperative pain relief. Continuous TPVB through a catheter is technically challenging and often unreliable. Intravenous dexamethasone extends the analgesic duration with some peripheral nerve blocks. However, data on the effect of intravenous dexamethasone on pain relief with TPVB are limited...

PURPOSE OF REVIEW: Total shoulder arthroplasty (TSA) is growing in popularity and is increasingly done on an ambulatory basis. This review examines recent developments in anesthesia and analgesia for ambulatory shoulder surgery. Pathway components are discussed and a sample pathway is described. RECENT FINDINGS: Adoption of pathways for shoulder surgery improves patient experience by reducing pain, opioid use, and side effects while improving patient satisfaction...

OBJECTIVE: Pain management strategies following palatoplasty vary substantially. Despite efforts to reduce narcotic utilization, specific analgesic regimens are typically guided by surgeon preference. Our aim was to define analgesic variables that affect postoperative narcotic use and time to resumption of oral intake. DESIGN: This is a retrospective review from 2015 to 2018. PATIENTS: Nonsyndromic patients undergoing primary palate repair...

BACKGROUND: Rebound pain occurs after up to 50% of ambulatory surgeries involving regional anaesthesia. To assist with risk stratification, we developed a model to predict severe rebound pain after foot and ankle surgery involving single-shot popliteal sciatic nerve block. METHODS: After ethics approval, we performed a single-centre retrospective cohort study. Patients undergoing lower limb surgery with popliteal sciatic nerve block from January 2016 to November 2019 were included...
