Under dosing of pain medication in emergency

Opioid dose escalation to effectively control pain is often linked to the current prescription opioid abuse epidemic. This creates social as well as medical imperatives to better understand the mechanistic underpinnings of opioid tolerance to develop interventions that minimize it, thereby maximizing the analgesic effectiveness of opioids. Profound opioid analgesic tolerance can be observed in the absence of mu-opioid receptor (MOR) downregulation, aggregate MOR G protein uncoupling, and MOR desensitization, in the absence of impaired G protein coupled receptor kinase phosphorylation, arrestin binding, or endocytosis...

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat symptoms of chronic inflammatory diseases such as osteoarthritis and rheumatoid arthritis; however, they are also associated with various adverse effects, including gastrointestinal (GI) bleeding and renal harm. As patients get older, some medications may no longer be beneficial or may even cause harm. Deprescribing is defined as the planned and supervised process of dose reduction or discontinuation of medications...

Anesthesia and intensive care, perioperative medicine and pain management, emergency medicine and resuscitation, all together constitute the field of action of the anesthesiologist. The definition of "anesthesiologist" underestimates the profession, and the lack of anesthesiologists seems understandable when we examine the scope of their activities throughout the hospital. There is little awareness among the public of the extent of the anesthesiologist's activity. The anesthesia segment itself, with all its importance, occupies a unique, yet modest part...

BACKGROUND: Nowadays, spinal anaesthesia is a suitable choice for most elective and emergency cesarean section (C-section) deliveries. AIM: This study aimed to determine the effect of adding low-dose naloxone to intrathecal morphine on postoperative pain and morphine related side effects after C-section. MATERIAL AND METHODS: In the present double-blind, randomised clinical trial, 70 women aged over 18 years, who were candidates for elective medical C-section under spinal anaesthesia were selected and randomly assigned to either the study group or the control group...

INTRODUCTION: Retinoids are vitamin A derivatives with numerous indications in dermatology. Acute pancreatitis is a rare adverse effect of systemic retinoids. We report a case occurring during acitretin treatment for psoriasis. PATIENTS AND METHODS: A 27-year-old male patient with no history of diabetes, obesity, alcohol consumption or medication consulted for extensive pustular psoriasis. The lipid balance and liver tests were normal. The patient was treated with acitretin at a dose of 25mg/d...

We present the rare case of a non-painful compartment syndrome of the forearm in a 35-year old man with a history of intravenous drug abuse, and lessons learned which would have enabled earlier consideration of this limb threatening condition and earlier therapeutic intervention.On initial assessment in the emergency department, the patient was drowsy, tachycardic and pyrexic. There was no obvious pain outwith expectation, and his forearm was erythematous and swollen. Due to the constellation of symptoms and signs, he was presumed to be septic from a forearm cellulitis and was thus treated for sepsis with intravenous antibiotics under the care of the medical team...

BACKGROUND: Upper limb injuries are common in children. When required, closed fracture reduction can be performed in the emergency department without general anaesthesia but causes pain. The primary objective of this study was to assess an oral analgesia protocol for fracture reduction without general anaesthesia. The secondary objectives were to look for associations linking pain intensity to age, sex, and waiting time and to determine the frequency of secondary displacement requiring closed reduction or internal fixation under general anaesthesia at the 1-week follow-up visit...

Introduction Over the past few years, there have been drastic advancements in the management of type 1 and 2 diabetes mellitus (DM). Prevention of complications is a prime concern of all physicians dealing with DM. However, whether or not these interventions have helped in reducing the incidence of diabetic ketoacidosis (DKA) in patients with type 1 DM, is still an unanswered question. The aim of this study is to assess the clinical pattern of DKA, evaluate its outcomes, and study the predictors of outcome...

RATIONALE: Clebopride is known as a dopamine antagonist used for alleviating emetic symptoms with minimal side effects. Herein, we report a case of acute dystonic reaction possibly caused by administration of clebopride in a young male. PATIENT CONCERNS: A 19-year-old with no special medical conditions, visited a local clinic complaining of abdominal discomfort, associated with nausea and vomiting. The patient was prescribed with tiropramide, clebopride, simethicone, and mosapride citrate, only to visit the emergency department for abrupt neck pain followed with dystonic reactions upon oral administration of the drugs...

We report the development and characterization of a novel, injury-free rat model in which nociceptive sensitization after red light is observed in multiple body areas reminiscent of widespread pain in functional pain syndromes. Rats were exposed to red light-emitting diodes (RLED) (LEDs, 660 nm) at an intensity of 50 Lux for 8 hours daily for 5 days resulting in time- and dose-dependent thermal hyperalgesia and mechanical allodynia in both male and female rats. Females showed an earlier onset of mechanical allodynia than males...

BACKGROUND: A long-acting prodrug of nalbuphine, nalbuphine sebacate, has been developed for meeting the unmet medical need of long-acting analgesics. Naldebain® (nalbuphine sebacate) has been developed as a new premedication for postoperative pain management. The primary objective of this study is to determine the efficacy and safety of a single dose of intramuscular Naldebain® in patients scheduled to undergo elective laparotomy. METHODS/DESIGN: A total of 110 patients will be recruited and randomized into two treatment groups...

INTRODUCTION: Low-dose methoxyflurane, administered via a hand-held inhaler, has been used for short-term pain relief in emergency medicine in Australia and New Zealand for over 40 years, and was recently approved in Europe for the rapid relief of moderate-to-severe trauma-related pain in adults. There is currently a lack of data for methoxyflurane versus active comparators, therefore this trial will investigate the efficacy and safety of inhaled methoxyflurane compared with standard of care (SoC) in the treatment of acute trauma-related pain in pre-hospital and ED settings in Italy...

INTRODUCTION: The inhalational analgesic low-dose methoxyflurane has been widely used by Australian ambulance services since 1975 and is now approved in Europe for emergency relief of moderate-to-severe trauma-related pain in conscious adult patients. The use of methoxyflurane in hostile environments is of special interest given its portability, ease of use and rapid onset of action. This trial will investigate the efficacy, tolerability and practicality of use of inhaled methoxyflurane in patients with moderate-to-severe trauma-related pain rescued from hostile mountainous environments by the Helicopter Emergency Medical Service (HEMS) in Italy...

OBJECTIVE: To describe our experience with intravenous lidocaine (IVL) to manage pain of renal colic origin in the emergency department (ED). METHODS: A retrospective analysis of all patients presenting with pain of renal colic origin from the periods of 2014 to 2017 by using the ED electronic medical record database (Allscripts™). RESULTS: Forty-four patients received IVL for renal colic over a three-year period. The average dose of IVL as a primary analgesic was 117...

Visceral pain, observed in inflammatory bowel disease (IBD) patients, is a challenging medical problem and remains poorly understood because the mechanisms underlying it are unclear. Emerging evidence indicates that microRNAs (miRNAs) play a crucial role in the pathogenesis of acute and chronic pain. In this study, we aimed to explore the potential role of miR-146a-5p (the mature form of miR-146a) in a mouse model of colitis induced by intracolonic injection of trinitrobenzene sulfonic acid (TNBS). We found that induction of colitis resulted in visceral hyperalgesia manifested by a decreased pain threshold to colorectal distension and upregulation of miR-146a-5p expression in the lumbosacral spinal cord...

BACKGROUND: Beta-blockers are a first choice migraine preventive medication. So far it is unknown how they exert their therapeutic effect in migraine. To this end we examined the neural effect of metoprolol on trigeminal pain processing in 19 migraine patients and 26 healthy controls. All participants underwent functional magnetic resonance imaging (fMRI) during trigeminal pain twice: Healthy subjects took part in a placebo-controlled, randomized and double-blind study, receiving a single dose of metoprolol and placebo...

OBJECTIVES: We compared the tolerability and efficacy of intranasal subdissociative ketamine to intranasal fentanyl for analgesia of children with acute traumatic pain and investigated the feasibility of a larger noninferiority trial that could investigate the potential opioid-sparing effects of intranasal ketamine. METHODS: This randomized controlled trial compared 1 mg/kg intranasal ketamine to 1.5 μg/kg intranasal fentanyl in children 4 to 17 years old with acute pain from suspected isolated extremity fractures presenting to an urban Level II pediatric trauma center from December 2015 to November 2016...

In response to increases in harms associated with prescription opioids, opioid prescribing has come under greater scrutiny, leading many health care organizations and providers to consider or mandate opioid dose reductions (tapering) for patients with chronic pain. Communicating about tapering can be difficult, particularly for patients receiving long-term opioids who perceive benefits and are using their medications as prescribed. Because of the importance of effective patient-provider communication for pain management and recent health system-level initiatives and provider practices to taper opioids, this study used qualitative methods to understand communication processes related to opioid tapering, to identify best practices and opportunities for improvement...

BACKGROUND CONTEXT: Postsurgical pain control is important in spine surgery as it can lead to earlier mobilization, decreased length of stay, decreased side effects from narcotic medications, and improved patient satisfaction. Liposomal bupivacaine (LB) is an injectable formulation of bupivacaine, providing prolonged local anesthesia, up to 72 hours postinjection. Although, LB has been used with increasing frequency following other musculoskeletal procedures, specifically total joint replacements, its pre-emptive analgesic effect following lumbar microdiscectomy has hitherto not been reported...

Methoxyflurane (MOF) a haloether, is an inhalation analgesic agent for emergency relief of pain by self administration in conscious patients with trauma and associated pain. It is administered under supervision of personnel trained in its use. As a consequence of supervised use, intermittent occupational exposure can occur. An occupational exposure limit has not been established for methoxyflurane. Human clinical and toxicity data have been reviewed and used to derive an occupational exposure limit (referred to as a maximum exposure level, MEL) according to modern principles...
