CONTEXT: The perception of pain due to an acute injury or in clinical pain states undergoes substantial processing at supraspinal levels. Supraspinal, brain mechanisms are increasingly recognized as playing a major role in the representation and modulation of pain experience. These neural mechanisms may then contribute to interindividual variations and disabilities associated with chronic pain conditions. OBJECTIVE: To systematically review the literature regarding how activity in diverse brain regions creates and modulates the experience of acute and chronic pain states, emphasizing the contribution of various imaging techniques to emerging concepts...

UNLABELLED: Morphine and fentanyl produce antinociception in part by binding to mu-opioid receptors in the periaqueductal gray (PAG). The present study tested the hypothesis that the PAG also contributes to the antinociceptive effects of other commonly used opioids (oxycodone, methadone, and buprenorphine). Microinjection of high doses of oxycodone (32-188 μg/.4 μL) into the ventrolateral PAG of the rat produced a dose-dependent increase in hot plate latency. This antinociception was evident within 5 minutes and nearly gone by 30 minutes...

Timely and appropriate pain management in the pre-hospital environment is paramount to effective patient care. Experts agree that there are many factors that hinder the delivery of adequate pain management to patients with pain. The purpose of this study was to use the Theory of Planned Behaviour (TPB) model to identify the factors influencing Ambulance Paramedics' intention to administer morphine to patients with pain. Participants of this study were Advanced Care and Intensive Care Paramedics who were deemed competent in morphine administration...

INTRODUCTION: Although pain is a major reason why patients summon emergency medical services (EMS), prehospital medical providers administer analgesic agents at inappropriately low rates. One possible reason is the role of EMS provider attitudes. OBJECTIVE: This study was conducted to elicit attitudes that may act as impediments or deterrents to administering analgesia in the prehospital environment. METHODS: A qualitative methodology was employed...

BACKGROUND: Recent advances in imaging have improved our understanding of the role of the brain in painful conditions. Discoveries of morphological changes have been made in patients with chronic pain, with little known about the functional consequences when they occur in areas associated with 'number-sense'; thus, it can be hypothesized that chronic pain impairs this sense. METHODS: First, an audit of the use of numbers in gold-standard pain assessment tools in patients with acute and chronic pain was undertaken...

This clinical policy from the American College of Emergency Physicians is the revision of a 2005 clinical policy evaluating critical questions related to procedural sedation in the emergency department.1 A writing subcommittee reviewed the literature to derive evidence-based recommendations to help clinicians answer the following critical questions: (1) In patients undergoing procedural sedation and analgesia in the emergency department,does preprocedural fasting demonstrate a reduction in the risk of emesis or aspiration? (2) In patients undergoing procedural sedation and analgesia in the emergency department, does the routine use of capnography reduce the incidence of adverse respiratory events? (3) In patients undergoing procedural sedation and analgesia in the emergency department, what is the minimum number of personnel necessary to manage complications? (4) Inpatients undergoing procedural sedation and analgesia in the emergency department, can ketamine, propofol, etomidate, dexmedetomidine, alfentanil and remifentanil be safely administered? A literature search was performed, the evidence was graded, and recommendations were given based on the strength of the available data in the medical literature...

Delta and mu opioid receptors (DORs and MORs) are inhibitory G protein-coupled receptors that reportedly cooperatively regulate the transmission of pain messages by substance P and TRPV1-expressing pain fibers. Using a DOReGFP reporter mouse we now show that the DOR and MOR are, in fact, expressed by different subsets of primary afferents. The MOR is expressed in peptidergic pain fibers, the DOR in myelinated and nonpeptidergic afferents. Contrary to the prevailing view, we demonstrate that the DOR is trafficked to the cell surface under resting conditions, independently of substance P, and internalized following activation by DOR agonists...
