A. SLUDGE describes the cholinergic effects in the body which cause the overstimulation commonly seen in a cholinergic crisis. The Mnemonic SLUDGE Organophosphate poisoning signs and symptoms can be easily remembered using the mnemonic SLUDGE (Salivation, Lacrimation, Urination, Defecation, Gastric problems, Emesis). Organophosphate Poisoning Bradycardia, Emesis, Lacrimation, and Salivation/Seizures/ Sweating. Started in 1995, this collection now contains 6897 interlinked topic pages divided into a tree of 31 specialty books and 737 chapters. J. Emerg. Organophosphate poisoning is poisoning due to organophosphates (OPs). 1, 3, 6 It is associated with depolarizing neuromuscular block (because of prolonged and high intrasynaptic concentrations of ACh). SLUGBAM. Introduction: • Organophosphate (OP) compounds are a diverse group of chemicals used in both domestic and industrial settings. Clipping is a handy way to collect important slides you want to go back to later. The initial dose for adults is 2 to 5 mg IV or 0.05 mg/kg IV for children until reaching the adult dose. BRYAN BALLANTYNE, HARRY SALEM, in Toxicology of Organophosphate & Carbamate Compounds, 2006. Organophosphate poisoning 1. Mnemonic devices used to remember the muscarinic effects of organophosphates are SLUDGE (salivation, lacrimation, urination, diarrhea, GI While onset of symptoms is often within minutes to hours, some symptoms can take weeks to appear. What are the most important initial manifestations of OP poisoning? Mnemonic devices used to remember the muscarinic effects of organophosphates are SLUDGE (salivation, lacrimation, urination, diarrhea, GI upset, emesis) and … Epidemiology Organophosphate poisoning is common, often as a result of suicidal ingestion (acute high-level exposure) or occupational exposure to pesticides (chronic low-level exposure) . findings of classical signs of organophosphate poisoning on examination, sometimes captured in the mnemonic “Dumbels” (Diarrhoea, Diaphoresis, Urination, Miosis, What is the fundamental difference between organophosphates and carbamates in deliberate self-poisoning as related to the outcomes? Acute poisoning is a dynamic medical illness usually representing an acute and potentially life threatening exacerbation of a chronic underlying psychosocial disorder — Lindsay Murray. Organophosphates are used as insecticides, medications, and nerve agents. Weissman BA, Raveh L. Therapy against organophosphate poisoning: the importance of anticholinergic drugs with antiglutamatergic properties. 3 The initial signs and symptoms of cholinergic toxicity are often muscarinic. Organophosphate poisoning results from exposure to organophosphates (OPs), which cause the inhibition of acetylcholinesterase (AChE), leading to the accumulation of acetylcholine (ACh) in the body. Nerve agents are organophosphate compounds that inhibit cholinesterase at the synaptic and neuromuscular junctions causing an excess of acetylcholine leading to a cholinergic crisis.Five nerve agents have been produced as weapons: tabun, sarin, soman, … Pharmacists Adolf Schall and Ernst Ratzlaff and the synthesis of tabun-like … The effects of organophosphate poisoning on muscarinic receptors are recalled using the mnemonic SLUDGEM (salivation, lacrimation, urination, defecation, gastrointestinal motility, emesis, Organophosphate poisoning occurs most commonly as a suicide attempt in farming areas of the developing world and less commonly by accident. ORGANOPHOSPHATE POISONING (A53) Organophosphate poisonings may cause bronchospasm, an increase in pulmonary and nasal secretions, constricted pupils, vomiting, diarrhea, urinary incontinence, diaphoresis, and cardiac dysrhythmias including both bradycardia and AV blocks. “DUMBELS” (Table 132-1) is a helpful mnemonic.Nicotinic effects of excess acetylcholine at the neuromuscular junction include muscle spasm and fasciculations, followed … Apart from the LITFL toxicology page on this topic (which is of … What is the mnemonic to remember the symptoms of cholinergic toxicity? The effects of organophosphate poisoning are recalled using the mnemonic SLUDGE (Salivation, Lacrimation, Urination, Diaphoresis (or Defecation), Gastrointestinal motility, Emesis)Treatment. Following recovery from the cholinergic toxicity (“ cholinergic crisis ”) of an acute overexposure to OPs, a proportion of patients may develop, after approximately 2–4 weeks, a delayed-onset peripheral … Nicotinic effects are remembered via the mnemonic MTWHF: Mydriasis (rare), Tachycardia, Weakness, Hypertension, and Fasciculations. In organophosphate poisoning, an organophosphate binds to just one end of the acetylcholinesterase enzyme (the esteric site), blocking its activity. Deep tendon reflexes are frequently increased early on and decreased or absent later. The effects of organophosphate poisoning on muscarinic receptors are recalled using the mnemonic SLUDGEM (salivation, lacrimation, urination, defecation, gastrointestinal motility, emesis, miosis) [10] An additional mnemonic is MUDDLES: miosis, urination, diarrhea, diaphoresis, lacrimation, excitation, and salivation. 2 ACUTE DELAYED-ONSET NEUROLOGICAL EFFECTS. 12 102–103. Organophosphate poisoning. What does dumbbells stand for? 13481 people have seen this mnemonic. Rochelle A. Dicker, William P. Schecter, in Current Therapy of Trauma and Surgical Critical Care, 2008 Nerve Agents. FPnotebook.com is a rapid access, point-of-care medical reference for primary care and emergency clinicians. Can be divided into 3 broad categories, including (1) muscarinic effects, (2) nicotinic effects, and (3) CNS effects. Signs and symptoms of organophosphate poisoning. Quick thinking and doing first aid to stabilise the victim can reduce the mortality rate. The acetylcholinesterase enzyme has two parts to it , an acetylcholine molecule, bound at both ends to both sites of the enzyme, is cleaved in two to form acetic acid and choline. Atropine works by antagonizing the muscaric receptor. Awareness is crucial to prevent any organophosphate poisoning and is especially needed in rural and remote farms. The mnemonic DUMBELS (Diarrhea, Urination, Miosis, Bronchorrhea, Emesis, Lacrimation, Salivation) is often used for the cholinergic features. Atropine can be used as an antidote in conjunction with pralidoxime, though the use of "-oximes" has been found to be of no benefit, or possibly harmful, in at least two … As a result of cholinergic crisis, the muscles stop responding to the high synaptic levels of ACh, leading to flaccid paralysis, respiratory failure, and other signs and symptoms reminiscent of organophosphate poisoning. Presentation is highly variable due to differences in dose, agent toxicity, and type of exposure.

SLUDGE is defined as Salivation, Lacrimation, Urination, Defecation, Gastrointestinal Distress and Emesis (medical term; response to organophosphate poisoning) rarely. The mainstays of medical therapy in organophosphate (OP) poisoning include atropine, pralidoxime (2-PAM), and benzodiazepines (eg, diazepam). The SLUDGE mnemonic is also called Sludge Syndrome and describes the signs and symptoms of Organophosphate poisoning and exposure to nerve agents. SLUDGE stands for Salivation, Lacrimation, Urination, Defecation, Gastrointestinal Distress and Emesis (medical term; response to organophosphate poisoning). How does atropine work to treat organophosphate poisoning? Symptoms and diagnosis. Poisoning can occur due to occupational or accidental exposure, deliberate ingestion, or chemical warfare with nerve gases. The largest clinical series of organophosphate and carbamate poisoning in infants and children was published in 1988. - killer B's Organophosphate poisoning most commonly results from exposure to insecticides or nerve agents.OPs are one of the most common causes of poisoning worldwide, and are … Diarrhea, Urination, Miosis, Bradycardia, Bronchorrhea, Emesis, Lacrimation, and salivation.
