Korea represents high suicide rate by poisoning. Especially, since a lot of people died by high concentrated paraquat which has extremely high fatality rate, paraquat sales were prohibited in 2012. We investigated to find out how the prohibition of sales affected occurrence of pesticide poisoned patients and what kinds of influences did it have for severity and death rate. By targeting patients who visited emergency room by pesticide poisoning from 2010 to 2014, we researched insecticides poisoned patients and herbicidal poisoned patients grouped into 9 categories. Before and after 2012, We compared A term (2010, 2011) and B term (2013, 2014)’s pesticide occurrence, especially distribution of herbicide occurrence and compared hospitalization rate, hospitalization period, length of stay in ICU (Intensive Care Unit), severity, and death rate. The number of insecticide patients was 219 (37.4%) and the number of herbicide patients was 367 (62.6%) who visited emergency room in five years and the rate was similar every year. In case of paraquat, there was 70.5% decrease by 105 people for A term and 31 people for B term and increase of double for glyphosate, glufosinate, and other herbicides. The death rate was decreased but hospitalization was increased. There weren’t any difference of rate in ICU admission, intubation and ventilator therapy. By prohibition of using paraquat, the death rate by pesticide poisoning was decreased. However, patients who poisoned by other herbicides were increased, so hospitalization rate increased and there weren’t any difference at patient’s severity rates.
