Summary
Emergency Medicine physicians showed improved knowledge of opioid conversions immediately after an educational lecture and infographic. However, long-term retention of morphine milligram equivalents knowledge was limited, suggesting a need for consistent follow-up.
Area of Science:
- Medical Education
- Pharmacology
- Emergency Medicine
Background:
- Pain management in the emergency department frequently involves opioid medications.
- Accurate opioid conversion is crucial for balancing pain relief and preventing adverse effects.
- Physicians' limited knowledge of morphine milligram equivalents can lead to medication errors and adverse outcomes.
Purpose of the Study:
- To educate Emergency Medicine physicians and residents on opioid properties, metabolism, and conversion techniques.
- To assess the efficacy of a lecture and infographic in improving knowledge of morphine milligram equivalents.
- To standardize opioid prescribing and conversion methods within the emergency department.
Main Methods:
- A lecture and infographic on opioid equianalgesic doses and conversions were developed.
- Pre- and post-presentation surveys were administered to assess knowledge immediately and after 7 months.
- Surveys evaluated understanding of opioid metabolism, characteristics, and conversion techniques.
Main Results:
- A majority of participants showed improved scores on immediate post-presentation surveys compared to pre-presentation surveys.
- Knowledge retention decreased over the 7-month follow-up period, with most participants showing no score improvement.
- One participant demonstrated immediate knowledge gain but a decline at the 7-month mark.
Conclusions:
- The educational lecture and infographic effectively improved immediate knowledge of opioid conversions among physicians.
- Long-term retention of morphine milligram equivalents knowledge was lacking, indicating a need for ongoing education.
- Further studies with larger sample sizes are warranted to confirm the effectiveness of these educational tools.

01:15Opioid Analgesics: Synthetic and Semisynthetic Opioids
338
Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...

293
Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...

01:25Analgesia and Pain Management
661
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

01:17Drugs Affecting GI Tract Motility: Opioids as Antidiarrheal Agents
247
Diarrhea, a condition marked by frequent loose or watery bowel movements, can be triggered by multiple factors such as viral or bacterial infections, food intolerances, anxiety, medications, and digestive disorders. Symptoms may include abdominal pain, bloating, nausea, and cramping. Severe or prolonged diarrhea can lead to complications like electrolyte imbalances, malnutrition, and dehydration if left untreated.

01:22Opioid Receptors: Overview
1.1K
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...

01:18Drug Delivery: Enteral Route
514
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.
