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.
