Poisoning is the most common mode of unnatural death in South East Asia, causing hundreds of thousand deaths per year. Organophosphorus (OP) compounds are commonly used as pesticides. Easy availability and widespread use has increased the likelihood of poisoning with these compounds. The present study was done to predict severity in acute organophosphate poisoning with clinical scoring and serum pseudocholinesterase levels. Total 60 patients of acute organophosphorus poisoning patients are enrolled in the study after fulfilling inclusion and exclusion criteria. The study was done at IGMC Shimla, Himachal Pradesh in the period of june 2018 to July 2019. POP score was applied and serum psuedocholinestrase levels are estimated. Suitable statistical methods applied to assess correlation and variables. Majority of patients were aged between 21 to 40 years, with M:F ratio of 2:1. Most common consumed compound was chlorpyriphos and mainly for suicidal intent. Bradycardia was the most common clinical feature. There was significant correlation between the severity of poisoning categorized by the POP scale and the serum cholinesterase at the time of initial presentation of the patients, requirements of atropine on the first day of admission, the total amount of dose of atropine , atropine needed and the average duration of hospital stay(

Background: Organophosphorus poisoning (OPP) is a major global public health problem. Pralidoxime has been used in a complimentary role to atropine for the management of OPP. World Health Organization (WHO) recommends use of pralidoxime but studies regarding its role have been inconclusive, ranging from being ineffective to harmful or beneficial. Materials and Methods: The present study was undertaken to evaluate the effectiveness of pralidoxime. Eddleston's study was the most compelling factor for our study, as he showed worst outcomes using pralidoxime. Our practice of continuous use of pralidoxime was based on the WHO guidelines and the study by Pawar (2006), which showed better outcome with higher doses of pralidoxime. These conflicting results suggested that a re-evaluation of its use in our clinical practice was indicated. Results: There was no difference in mortality rates, hemodynamic parameters and atropine requirements between the AP and A groups. Mean duration of ventilation (3.6 ± 4.6 in AP group vs. 3.6 ± 4.4 in A group) and Intensive Care Unit stay (7.1 ± 5.4 in AP group vs. 6.8 ± 4.7 in A group) was comparable. Serum sodium concentrations showed a correlation with mortality, with lower concentrations associated with better outcomes. Conclusion: The study suggests that add-on WHO-recommended pralidoxime therapy does not provide any benefit over atropine monotherapy. Adding pralidoxime does not seem to be beneficial and at the same time does not result in increased mortality rates. Our practice changed after completion of this study, and it has proven to be of significant benefit to patients who had to bear the expense of treatment.

Objective: Organophosphorus poisoning (OPP) is a major concern for developing countries. There are no guidelines for the prophylactic use of antibiotics in the management of OPP which in such critical cases might add to the economic burden of the patients as well as antibiotic resistance. We compared the health and economic outcomes in patients prescribed with prophylactic antibiotics with respect to the patients not prescribed with any antibiotics. Methods: A retrospective observational study was carried out for two years for patients admitted to ICU with OPP. Patients were graded for severity of OPP, and divided into two groups based on prophylactic prescription and no prescription of antibiotics. The length of stay (LOS), hospitalization cost and outcomes were measured and compared between the two groups using statistical tests. Results: Out of the 254 patients observed, 108 were prescribed with prophylactic antibiotics and 94 were not prescribed with any antibiotic. There was a significant difference between LOS, cost of treatment and outcomes in the two groups (p

A 32-year-old male presented with a history of consuming some organophosphorous compound with suicidal intention. He was treated with atropine, pralidoxime, ventilator support. During stay patient had persistent irritability, tachycardiaand hypertension despite sedation and labetalol infusion. He developed headache, visual blurring hemiparesis and focal seizures. Magnetic resonance imaging of the brain revealed multifocal hyperintensities mainly in subcortical areas of parietal and occipital regions in T2-weighted images, with increased values of Apparent Diffusion Coefficient, suggesting posterior reversible encephalopathy syndrome (PRES). The possibilities of PRES caused by organophosphorous poisoning either due to hypertension caused by autonomic deregulation or direct neurological toxicity has been discussed.

Introduction: Pesticide poisoning is a major health problem worldwide. In Nepal the most common cause is suicidal and pesticides account for more than fifty percent of cases. The objective of the study was to look in detail regarding the pesticide poisoning cases admitted at BPKIHS; their epidemiological profile, presentation, treatment and their outcome during the hospital stay. Drug therapy included specific antidotal drugs; atropine and pralidoxime (PAM) and some nonspecificdrugs: antimicrobials and sedatives. Methods: It was a retrospective study which included 2621 patients with poisoning of which 1661 cases were related to pesticides. Results: The mean age at presentation was 29 years. The mean duration of hospital stay was 6.7 days. The majority of patients 81.16% showed improvement whereas 6.6% of patients died within 24 hours of admission and 3.54% after 48 hours of admission. Among all the patients 0.5% patients were given ICU care and all others were managed in the different units of medicine ward. The total amount of atropine administered varied considerably from patient to patient, according to the need. Most of the cases were under the influence of alcohol. All the patients had a psychiatry evaluation before discharge. Conclusions: Pesticide poisoning is increasing in incidence and it is one of the preventable public health problems and includes mainly the patients’ age group 20-30 years. Due to easy availability of pesticides it is the most preferred method of suicide, the main reasons being impulsive act and increased indebtedness in the society.

A retrospective study of poisoning cases admitted in ICU [Department of Anaesthesiology and Critical Care GMC Srinagar] from Jan 2006 to May 2014 was conducted to evaluate the socio demographic variables and type of poison consumed in these cases. Organophosphorous poisoning cases were predominant, amounting to 394 cases. Maximum cases (281) were in the age group of 18 to 35 years. Female predominance was seen in the study population. It was observed that unmarried people (294) had high incidence of poisoning as compared to married people (150). Most of the cases admitted in ICU were from south zone (204) which had a population of 2,328,950 as compared to central (129) and north (111) zones of Kashmir that had a population of 1,250,173 and 2,573,169 respectively.

Organophosphorous (OP) compound poisoning is one of the most common causes for admission to the Medical Intensive Care Unit. The morbidity and mortality associated with OP poisoning is due to the action of the compound at the muscarinic, nicotinic receptors, and the central nervous system. Here is a rare case of extrapyramidal manifestations occurring in the intermediate phase of OP poisoning, use of amantidine led to subsiding of the symptoms.
