magnesium analgesia

INTRODUCTION: Previous trials favored a continuous interscalene brachial plexus block over a single injection for major shoulder surgery. However, these trials did not administer a multimodal analgesic regimen. This randomized, controlled unblinded trial tested the hypothesis that a continuous infusion of local anesthetic for an interscalene brachial plexus block still provides superior analgesia after major shoulder surgery when compared with a single injection in the setting of multimodal analgesia, inclusive of intravenous dexamethasone, magnesium, acetaminophen and ketorolac...

Anesthesia for major head and neck surgery is historically heavily reliant on opioids with deleterious consequences. We reported a case of a patient with a history of heroin abuse submitted to a tongue carcinoma excision, followed by free-flap reconstruction under opioid-free anesthesia. We used a propofol total intravenous anesthesia and perfusions of ketamine, dexmedetomidine, lidocaine, and magnesium sulfate for analgesia, complemented by boluses of dexamethasone, acetaminophen, parecoxib, and metamizole...

OBJECTIVES: Intertrochanteric fracture is a common fracture that mainly occurs in the elderly. Diverse pain management strategies have been applied; however, considering the age of the patients, analgesia-related complications should be concisely considered. The current study aims to evaluate the efficacy and adverse effects of Ketorolac plus placebo versus Ketorolac plus magnesium sulfate for pain management in intertrochanteric fractures. METHODS: The current randomized clinical trial has been conducted on 60 patients with intertrochanteric fractures assigned into two groups of treatment with Ketorolac (30 mg) plus placebo (n=30) versus Ketorolac (30 mg) plus magnesium sulfate (15 mg/kg) (n=30)...

BACKGROUND: Peripheral regional anaesthesia is frequently used for upper extremity surgery. To prolong the duration of analgesia, adjuvants can be added to single-injection local anaesthetics. Despite attempts to compare several adjuvants in pairwise meta-analyses, a comprehensive comparison is still missing. OBJECTIVE: The objective of this network meta-analysis was to determine the effectiveness of adjuvants in upper extremity peripheral nerve blocks. DESIGN: A systematic review of randomised controlled trials with network meta-analyses...

BACKGROUND AND AIMS: Inguinal hernia repair is associated with moderate to severe pain that is most extreme in the first 24 hours. The aim of this study was to compare the efficacy of dexamethasone versus magnesium sulphate (MgSO4 ) with bupivacaine in ultrasound-guided transversus abdominis plane (TAP) block for patients undergoing unilateral inguinal hernioplasty. METHODS: Eighty patients were randomly allocated to two groups to receive ultrasound-guided TAP block postoperatively with either 20 ml of 0...

Pain is the leading cause of medical consultations and occurs in 50-70% of emergency department visits. To date, several drugs have been used to manage pain. The clinical use of ketamine began in the 1960s and it immediately emerged as a manageable and safe drug for sedation and anesthesia. The analgesic properties of this drug were first reported shortly after its use; however, its psychomimetic effects have limited its use in emergency departments. Owing to the misuse and abuse of opioids in some countries worldwide, ketamine has become a versatile tool for sedation and analgesia...

Background Major abdominal surgeries are often accompanied by excruciating pain, which, if not adequately managed, can reduce patient comfort and satisfaction, delay mobilization, compromise respiratory and cardiac functioning, and increase healthcare costs. The transversus abdominis plane (TAP) block is an efficient and safe complement to multimodal postoperative analgesia for abdominal surgery. This study evaluates the efficacy of combining magnesium sulfate (MgSO4 ) with bupivacaine for TAP block in patients posted for total abdominal hysterectomy (TAH)...

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...

In the magnesium sulfate group, patients were given a periarticular infusion of a cocktail of analgesics consisting of epinephrine, ropivacaine, magnesium sulfate, and dexamethasone...

Mast cell degranulation impacts the development of pain and inflammation during tissue injury. We investigated the antinociceptive effect of a combination of cromoglycate and magnesium in the orofacial model of pain and the histological profile of the effect of magnesium in orofacial pain. In male Wistar rats, formalin (1.5%, 100 µL) was injected subcutaneously into the right upper lip of rats after cromoglycate and/or magnesium. Pain was measured as the total time spent on pain-related behavior. Toluidine blue staining was used to visualize mast cells under the light microscope...

Introduction : Opioids are the "gold standard" for pain treatment during and after colorectal surgery. They can inhibit cellular and humoral immunity and it is assumed that can promote cancer cell proliferation and metastatic spread. Adequate pain management can be achieved not only with opioids, but also with non-opioid drugs, which can be used together in small doses, i.e., multimodal analgesia, and can lower the need for opioids during and after surgery. Opioid free anesthesia (OFA) is part of multimodal analgesia, where opioids are not used in the intraoperative period...
