Poisoning with 2,4-dichlorophenoxyacetic acid treated by hemodialysis

Abstract

In this paper four patients are presented who had been poisoned by 2,4-dichlorophenoxyacetic acid (2,4-D). The first patient, aged 51 years, had attempted to commit suicide by taking orally 400 ml of a 40% solution of 2,4-D. He was admitted in a coma, 6.5 h after poisoning. Extracorporal hemodialysis was performed and the course of the illness was satisfactory. The second patient, aged 80 years, had accidentally drunk 100 ml of a 40% solution of 2,4-D. He was admitted in a coma a few hours after poisoning. Hemodialysis and resin hemoperfusion were performed and the course of the illness was satisfactory. Prior to the above therapy the patient had a 2,4-D serum concentration of 177 mg/100 ml. 2,4-D clearance was 56.3 ml/min during this therapy. The third patient, aged 24 years, had drunk 200 ml of a 40% solution of 2,4-D in a suicide attempt, and paraquat poisoning was also suspected. He was admitted 10 h after poisoning and immediately hemodialysis and hemoperfusion were carried out: the course of the illness was satisfactory. On admittance the concentration of 2,4-D in serum was 122.5 mg/100 ml, and clearance was 72.9 ml/min during treatment. The fourth patient, aged 50 years, had accidentally drunk 100-200 ml of a 40% solution of 2,4-D. He was admitted in a coma 3 h after poisoning. Hemodialysis was performed and the course of the illness was satisfactory. On admittance the concentration of 2,4-D in serum was 37 mg/100 ml and clearance was 68.7 ml/min.(ABSTRACT TRUNCATED AT 250 WORDS)

A Multicultural, Multiethnic, and Multiconfessional Bosnia and Herzegovina: Myth and Reality

“…At the same time the city could boast the publication of 89 different newspapers, including 11 in German, two in Turkish, one each in Spanish and Hungarian, and two bilingual German-Serbo-Croatian papers. 24 The Habsburg policy for economic development in BiH led to the construction of roads, railways, and model farms. However, the expected agrarian reform never materialized, and Bosnian Muslims retained much of their wealth and privilege.…”
