Outcome was measured according to GCS score in terms of mortality during hospital stay. necessary precautions to avoid such incidents. It can be caused by large or small doses. PDF | Acute poisoning by organophosphorus (OP) compounds is a major global clinical problem, with thousands of deaths occurring every year. Results: A total of 62 patients with the diagnosis of acute organophosphate poisoning were registered The gender distribution was almost equal in this study with 33 (53.2%) male patients and 29 (46.8%) females. Patients suffering from other systemic illness like diabetes mellitus, hypertension, ischemic heart disease, which could affect mortality were excluded from the study. Furthermore, Gunell et al, 2007 calculate that the Eighty patients (47 female, and 33 male) were managed. The 2nd step is stripping off immediately the contaminated clothes and give an extensive wash to the body with soap and water. organophosphate poisoning. Fortunately, terrorist or warfare use of OP is rare but the potential exists to expose a great many people at once. In addition to atropine and oximes, the followings have recently been used successfully for the treatment of OP poisoning.1. organophosphate poisoning and terrorism. Organophosphate poisoning is poisoning due to organophosphates (OPs). Presentation is highly variable due to differences in dose, agent toxicity, and type of exposure.

In the early part of the 19th century however, before Williamson, the direct reaction between the "spirit of wine" (ethanol) and acids was the only method of generating the elusive "ethers". Ronnel produces mild signs of poisoning in cattle at 132 mg/kg, but severe signs do not appear until the dosage is >400 mg/kg. securing Airway, Breathing and Circulation, administering atropine at a dose of 2 mg every 10 minutes till reversal of cholinergic symptoms and administering a stat dose of pralidoxime 1 gram. The early days of ether chemistry can be divided into two periods: before and after Williamson serendipitous discovery (1851) of a new and efficient way to produce ethers using ethyl iodide and potassium salts. Among these patients, majority (88.7%) took rat killing pills/powder as poison,3.2% took insecticide spray while 8.1% of the patients took anti lice lotion. Organophosphorus (OP) compounds constitute a heterogeneous category of chemicals Intentional self-harm tends to involve much higher doses than accidental exposure.

The latter compounds can also increase the synthesis of glutathione, which can both ameliorate the OP-induced oxidativestress and enhance OP detoxification.It is concluded Sodium bicarbonate, Magnesium sulfate and the antioxidants should be added to the standard treatment of OP poisonings. 2.5% (n = 2) patients expired. Organophosphate poisoning may cause significant morbidity and mortality due to seizure activity. especially India, should concentrate on the optimization and monitoring of usage of OP The first 5 minutes of exposure … Glasgow Coma Scal, out of 44 patients in the group having GCS. The wide availability, lack of rules and regulations for the sale of pesticides resulted in wide spread use of Organophosphate as one of the most common poison used for deliberate self-harm.Methods: In this study, authors aim to find out clinical profile with respect to different O.P. The OP, neighboring countries Iran and India a, solvents, for example xylene, and emulsifiers in the, muscles. Chances of survival was better in persons who reached early to the hospital. The mean time since poison taken was 1.3 + 0.7 hours ranging from 0.25 to 4.0 hours. specifically designed for the control of pests, weeds or plant diseases. However, the evidence for this effect is inconclusive. Organophosphorous (OP) chemical warfare nerve agents mainly sarin and tabun were used during the Iran-Iraq war with high mortalities. Mean patient age was 24.35 +/- 7.69 years. 2. Aim: To describe The incidence of poisoning was 75 per 100 000 population and the death rate was very high (22 per 100 000 population). However, some of the complications following OP poisoning are neurological and involve neurologists. These toxic molecules can be counteracted by antioxidants such as vitaminsC and E, spin traps, melatonin and low molecule weight thiols. In: Hoffman RS, Nelson LS, Howland MA. The mean age of patients was 23.3 + 6.1 years ranging from 14 to 40 years. our review suggested antioxidants should be administered for OP poisoning patients to reduce after severe poisoning due to sarin, a weaponized organophosphate compound struc-turally similar to the insecticides.28 Some of the most commonly reported early … Conclusion: Although serum cholinesterase values can be used in the quick diagnosis, their efficiency at predicting outcome in patients with OP poisoning has not been established. Strict legislation regarding the sale, distribution and storage of agrochemicals could result in the reduction of mortality and perhaps the incidence of poisoning, in developing agricultural countries. Overall 9 (14.5%) of study patients required intubation and/or ventilation, while 1 (1.6%) patient died in our study due to poisoning. Headquarter Hospital Rawalpindi.Duration of study. Case fatality of intentional-poisoning in developing countries is as high as 10-20%, due to … Organophosphate poisoning can be short- or long-term.

Organophosphate Poisoning [created by Paul Young 02/10/07] general - Organophosphorus pesticides are the most important cause of severe toxicity and death from acute poisoning worldwide, with more than 200 000 deaths each J Pak Med Assoc 2008; 58:455-, organophosphate poisoning. Background: Poisoning is the most common method, employed for the act of deliberate self-harm. Our review article mainly Sodium Bicarbonate: Infusion of high doses of sodium bicarbonate (5 mEq/kg in 60 min. 3. •Organophosphate widely used in agricultural sector as PESTICIDES. Organophosphate poisoning is the most widely recognized pesticide poisoning in developing nations (1, 2). We conclude that in future, the ministry of agriculture of developing countries Introduction: • Organophosphate (OP) compounds are a diverse group of chemicals used in both domestic and industrial settings. Postmortem examinations revealed a wide shiny blue colouration of the antecubital region with oedematous muscular fascia and focal liquefaction necrosis. Acute organophosphate (OP) poisoning is one of the most common poisonings in emergency medicine and toxicological practice in some of the less-developed nations in South Asia. Pesticide self-poisoning accounts for one-sixth to one-eighth of the world's suicides and a third of suicide deaths in rural Revista de Pesquisa: Cuidado é Fundamental Online, 2013, The care of the child with chronic or disabling disease in the hospital context, Nursing and solid waste management of health services, Cuidado de enfermagem segundo a teoria de Orem: assistência a paciente com transtorno afetivo bipolar, Need to move and maintain a good posture in elderly on surgery: quasi-experimental study, Therapeutic communication in the context of male healthcare. Traditionally, OP poisoning comes under the domain of emergency physicians, internists, intensivists, and toxicologists. Prevalence of OP was accounted for as 10-36.2% in developed nations, 40 … There is a much higher incidence in rural areas of the third world. You can download the paper by clicking the button above. Organophosphorus pesticide self-poisoning is an important clinical problem in rural regions of the developing world, and kills an estimated 200 000 people every year. Our review article examines pathophysiology, clinical Crit Care 2004;8(6):R391-7. If the organophosphate does not leave the acetylcholinesterase enzyme within 24 to 48 hours, it is bound irreversibly to the enzyme, which is permanently inactivated; this process is called “aging.” Recovery from poisoning occurs ORGANOPHOSPHATE POISONING AND MANAGEMENT 1. Sixteen (25.8%) patients presented with GCS < 13 while 46 (74.2%) presented having GCS of > 13. 965 ORIGINAL ARTICLE Acute Organophosphate Poisoning in University Hospital Emergency Room Patients Yusuf Yurumez1, Polat Durukan 2, Yucel Yavuz1, Ibrahim Ikizceli2, Levent Avsarogullari , Seda Ozkan2, Okhan Akdur2 and Caglar Ozdemir3 Therapeutic agents that can ameliorate nicotinic manifestations, mainly neuromuscular, are oximes. There is also a need to study the effect of oximes on the neurophysiological abnormalities. Acute organophosphate (OP) poisoning is one of the most common poisonings in emergency medicine and toxicological practice in some of the less-developed nations in South Asia. Severe morbidity and mortality occurs in patients having GCS levels of < 13. There are no accurate figures kept about the incidence of OP poisoning. Nine (56.3%) out of 16 patients with GCS < 13 needed intubation compared to none out of 44 patients in the group having GCS > 13. compounds, prognosis and outcome of each patient in relation to the delay in getting medical attention. Three (12%) of the 25 patients (male-female ratio, 12:13) died. He wants Patients with acute DSP, defined as "ingestion of a poison or excessive dose of a medicine for self-harm" were included. manifestations, toxicokinetics of OP poison, its prevention and management. Log out of ReadCube. Our case report emphasizes the necessity of a detailed crime scene investigation and postmortem examination for the possibility of homicide in such cases. Methods: In this descriptive study patients of age >13 years of either gender, who themselves or attendants gave history of intake of organophosphate (OP) containing substance, or presenting with such substance (Rat killing pills/powder, anti lice lotion, or insecticide), were included. On February 13, 2017, Kim Jong-nam, the half-brother of North Korean leader Kim Jong-un, died at Kuala Lumpur airport in Malaysia. Benzodiazepines (31.3%) and organophosphate (OP) compounds (21.3%) were commonly used for DSP. We present the first ever case of homicidal poisoning due to injection of methidathion, an organophosphate insecticide. 66, No. Unlabelled: Treatment of Organophosphate Poisoning In his article Nachmansohn (1) said that "Pyridine 2-aldoxime methiodide is much more efficient and less harmful than atropine, still frequently applied by physicians in organophosphate a So, we searched Science Direct, Medline and PubMed bibliographic databases There is a good correlation between the electrophysiological abnormalities and the severity of the clinical manifestations. Treatment of organophosphate poisoning: The first step in the treatment is to remove the patient from the source. Conclusion: GCS level is an important factor in assessing Organophosphate poisoning. Neurophysiological abnormalities characteristic of nicotinic junctions (mainly neuromuscular junction) dysfunction include: (1) single, supramaximal electrical-stimulus-induced repetitive response/s, (2) decrement-increment response to high frequency (30 Hz) repetitive nerve stimulation (RNS), and (3) decremental response to high frequency (30 Hz) RNS. Background and Objectives: Organophosphate poisoning (OP) is a serious clinical condition that may sometimes be fatal. This leads to too much acetylcholine at receptors in the autonomic nervous system, the CNS and the neuromuscular junction. ISSN 2175-5361 DOI: 10.9789/2175-5361.2013v5n3p218 Ribeiro JLS, Pereira CDFD, Fernandes LGG et al. It has also been determined that serum leukocyte values have no prognostic value in OP poisoning, but GCS values have been found to be effective in predicting the outcome. Occup Med 2004;54:69-. Unintentional poisoning kills far fewer people but is a problem in places where highly toxic organophosphorus pesticides are available. [4] Organophosphates are used as insecticides, medications, and nerve agents. This may be due to the fact that there are several factors that determine the therapeutic effect of oximes. exposure. The aim of this study was to determine whether the Glasgow coma scale (GCS), and serum acetylcholinesterase and leukocyte levels have prognostic value in acute OP poisoning.
