The maximum recommended daily dose of Epidiolex is 20 mg/kg. 64 patients with moderate-severe odontogenic pain participated in the study and REDCap software was utilised to randomly assign participants into groups: CBD10 (10 mg/kg), CBD20 (20 mg/kg) and placebo...

Optimal pain relief in day-case surgery is imperative to patient comfort and timely discharge from hospital. Short-acting opioids are commonly used for analgesia in modern anaesthesia, allowing rapid recovery after surgery. Plasma concentration fluctuations from repeated dosing of short-acting opioids can cause patients to oscillate between analgesia with potential adverse effects, and inadequate analgesia requiring rescue dosing. Methadone's unique pharmacology may offer effective and sustained analgesia with less opioid consumption, potentially reducing adverse effects...

INTRODUCTION: Alleviating pain and anxiety of patients during procedures is an essential skill for an Emergency Physician (EP). Several sedatives and dissociative agents are used for PSA (Procedural Sedation and Analgesia). In this study, we aimed to compare two drugs that is, ketamine and fentanyl for procedural sedation in adults with isolated limb injuries in the Emergency Department (ED). MATERIALS AND METHODS: In this prospective, randomised controlled interventional trial, patients aged between 18 to 65 years with isolated extremity injury requiring PSA in the ED were recruited...

The goal of palliative care is to focus on the holistic needs of the patient and their family versus the pathology of the patient's diagnosis to reduce the stress of illness. U.S. servicemembers deployed to austere environments worldwide have significantly less access to palliative care than in military treatment facilities in the U.S. Preparation for future conflicts introduces the concept of prolonged medical management for an environment where urgent casualty evacuation is impossible. Ketamine is currently widely used for analgesia and anesthesia in the care of military service members and its use has increased in combat zones of Iraq and Afghanistan due to the favorable preservation of respiratory function, minimal changes in hemodynamics, and lower pain scores compared to opioids...

Ketamine is an NMDA-receptor antagonist that produces sedation, analgesia and dissociation at low doses and profound unconsciousness with antinociception at high doses. At high and low doses, ketamine can generate gamma oscillations ( > 25 Hz) in the electroencephalogram (EEG). The gamma oscillations are interrupted by slow-delta oscillations (0.1-4 Hz) at high doses. Ketamine's primary molecular targets and its oscillatory dynamics have been characterized. However, how the actions of ketamine at the subcellular level give rise to the oscillatory dynamics observed at the network level remains unknown...

BACKGROUND: Colonoscopy is a commonly performed gastroenterological procedure in patients associated with anxiety and pain. Various approaches have been used to provide sedation and analgesia during colonoscopy, including patient-controlled analgesia and sedation (PCAS). This study aims to evaluate the feasibility and efficiency of PCAS administered with propofol and remifentanil for colonoscopy. METHODS: This randomized controlled trial was performed in an authorized and approved endoscopy center...

OBJECTIVE: To analyze the application of Dezocine combined with psychological care in the postoperative pain management. METHODS: This is a retrospective study. A total of 186 HFS patients who underwent Microvascular Decompression (MVD) at First People's Hospital of Zunyi between January 2020 and January 2022 were selected as the study subjects. Patients were divided into two groups based on different treatment interventions. The control group (n = 93) received routine perioperative care without preemptive analgesia, while the observation group (n = 93) received preemptive analgesia and combined psychological care on the basis of the control group's intervention...

BACKGROUNDS: Ketamine possesses analgesia, anti-inflammation, anticonvulsant, and neuroprotection properties. However, the evidence that supports its use in mechanically ventilated critically ill patients with COVID-19 is insufficient. The study's goal was to assess ketamine's effectiveness and safety in critically ill, mechanically ventilated (MV) patients with COVID-19. METHODS: Adult critically ill patients with COVID-19 were included in a multicenter retrospective-prospective cohort study...

BACKGROUND: Propofol is the drug of choice for procedural sedation. The addition of α2 agonist dexmedetomidine may improve the safety profile of the procedure by providing stable hemodynamics, better sedation quality, and decreasing the side effects of each drug during elective endoscopic retrograde cholangio-pancreaticography (ERCP). MATERIALS AND METHODS: Eighty patients aged between 18 and 60 years were distributed randomly into two groups. The dexmedetomidine + propofol group (group DP) received an injection of dexmedetomidine at the dose of 1 mcg/kg in 100 mLsaline, and the propofol group (group P) received plain 100 mL normal saline over 10 min...

The α2-adrenoceptor agonist dexmedetomidine is a commonly used drug for sedatives in clinics and has analgesic effects; however, its mechanism of analgesia in the spine remains unclear. In this study, we systematically used behavioural and transcriptomic sequencing, pharmacological intervention, electrophysiological recording and ultrasound imaging to explore the analgesic effects of the α2-adrenoceptor and its molecular mechanism. Firstly, we found that spinal nerve injury changed the spinal transcriptome expression, and the differential genes were mainly related to calcium signalling and tissue metabolic pathways...

BACKGROUND: Providing analgesia and sedation is an essential component of caring for many mechanically ventilated patients. The selection of analgesic and sedative medications during the COVID-19 pandemic, and the impact of these sedation practices on patient outcomes, remain incompletely characterized. RESEARCH QUESTION: What were the hospital patterns of analgesic and sedative use for patients with COVID-19 who received mechanical ventilation (MV), and what differences in clinical patient outcomes were observed across prevailing sedation practices? STUDY DESIGN AND METHODS: We conducted an observational cohort study of hospitalized adults who received MV for COVID-19 from February 2020 through April 2021 within the Society of Critical Care Medicine Discovery Viral Infection and Respiratory Illness Universal Study (VIRUS) COVID-19 Registry...
