Prospective analysis of intoxicated patients developing shock and/or organ failure.

BACKGROUND: Data on intoxication patients with shock and acute organ failure is valuable for the prediction of the tailored scale prognosis of the patients in the emergency department. METHODS: : Our study was designed prospectively as a cross-sectional and observational over the course of four years. The patients over 18 years of age were included and the epidemiological data related to development of shock and acute organ failure, the treatments, and the outcome were recorded. The organic phosphate severity score was also calculated for all patients. RESULTS: A total of 89 patients with shock and/or acute organ failure 72 (80.9%) of the patients were males. Methanol (51 patients, 57.3%) was the most common cause of intoxications followed by cardiovascular agents. Thirty (33.7%) patients died despite all treatments and mortality was found to be higher in patients with hypotension (p = 0.031) at the time of admission to the emergency department and in those with a high organic phosphate poisoning severity index (p = 0.001). High levels of WBC, creatine, lactate, base excess and low bicarbonate and blood pH were associated with mortality. The discharge rates of patients who received extracorporeal treatment were statistically higher than those who did not receive this treatment (p = 0.001). DISCUSSION: The organic phosphate poisoning severity score can partially help us to predict the prognosis in all poisoning patients at the time of the first presentation. Emergency physicians may consider the development of hypotension, high creatine, lactate, base excess, low bicarbonate, and blood pH to be associated with a poor prognosis in the first hours of admission in acute poisoning patients. In these patients, it was predicted that the addition of selected extracorporeal methods without delay, in addition to the treatments that should be applied, may increase the survival rate.

Organophosphate Poisoning: Demographics, Severity Scores and Outcomes From National Poisoning Control Centre, Karachi.

Introduction Organophosphate ingestion is the commonest cause of self-harm encountered at poison control centers in Pakistan. It usually affects a young populous. Organophosphates are found in various forms and formulations that are easily accessible to the general public. These compounds are extremely potent poisons causing rapid clinical deterioration with minimal ingestion or exposure. Signs and symptoms can range from mild or none to severe such as bradycardia, miosis, fasciculations, seizures and altered level of consciousness. Poisoning severity is measured using the Peradeniya Organophosphorus Poisoning (POP) scale. Mortality rates are relatively low for mild to moderate disease. Severe disease as calculated by the POP carries an exceptionally high mortality rate. The National Poisoning Control Centre (NPCC) at Jinnah Postgraduate Medical Centre, Karachi treats an extraordinary number of poisoning cases on a daily basis. Despite this data pertaining specifically to OP ingestion is nearly absent. There have been no studies analyzing the various aspects of organophosphate poisoning in the last 30 years to the best of our knowledge. Here, we look to rectify this. Aims To evaluate the demographics, severity scores and outcomes of organophosphate poisoning cases in the last year from the NPCC, Karachi. Methods This was a retrospective study. It was held from 1st January 2019 to 31st December 2019. All data was recorded from patients admitted to the NPCC with a proven diagnosis of organophosphate poisoning. Results Three thousand and three hundred patients were inducted into this study. Over 3/4th of the patients were teenagers or aged less than 30 years. Almost all referrals were made from within the city. Overall survival rate at 28 days was 89.45%. Most patients presented with mild to moderate disease as calculated by the POP; severe disease had a mortality rate of nearly 50%. Conclusion Organophosphates make up a significant portion of all cases of poisoning treated at the NPCC. The POP is an excellent tool to evaluate disease severity. Overall survival rates are good but mortality rate is high for severe disease even in young patients.
