To investigate acute drug intoxication trends in the elderly visited Emergency Medical Centers, Data was collected from the records of poisoning patients visited Five different Hospitals from January 1. 2007 to December 31. 2007. The analysis was conducted by using 135 cases of 624 cases. When considering only the elderly and making comparisons between the urban areas and the rural areas the following data was produced. In regard to patients with acute drug intoxication, the main substance of choice was pesticides. Cases of acute drug intoxication are definitely higher for those categorized as the rural elderly (75.0%) when compared with those categorized as the urban elderly (44.1%). The male to female ratio, those living together as a family, past suicide attempts, mental state and sobriety condition when they came, monthly distribution etc. between the two groups did not demonstrate a difference between them. In regard to reasons given for acute drug intoxication, suicide was the highest at 60.7% of the cases. When comparing accidental reasons for poisoning, the urban elderly, at 34.2% of their cases, were higher than in the rural elderly, at 23.7%. After first aid was administered, the admission rate was higher for the rural elderly (47.4%) than for the urban elderly (33.9%). This shows that the rural elderly have a more severe acute drug intoxication poisoning problem than the urban elderly do.

한 대학병원 응급실에 방문한 응급환자들이 방사선에 얼마나 피폭되는지를 알아보고자, 2006년 3월 16일 부터 31일까지 15일 동안 방문환자 200명을 임의 추출하여 방사선 피폭선량을 측정한 결과는 다 음과 같다 1. 연구대상자의 분포는 타병원전원환자 50명(25.0%), 교통사고환자 24명(8.3%),기타사고환자 50명 (25.0%), 일반환자 76명(38.0%)이었다. 2. 환자의 방사선 촬영횟수를 보면 환자 1인당 타병원, 전원환자 6.4회, 교통사고환자 14.5회, 사고환 자 2.6회, 일반환자 2.4회로 교통사고환자들이 타환자군에 비해 방사선촬영 건수가 3～4배 많았다 3. 환자의 방사선촬영종류별 피폭선량을 보면 일반촬영 28.9mGy, CT촬영 84.2 mGy, 특수촬영 1.02mGy로 CT촬영피폭이 일반촬영 비해 10배 정도 많았다. 4. 환자의 평균 방사선 피폭선량을 보면 타병원 전원환자는 24.6mGy, 교통사고환자는 55.2 mGy, 사 고환자는 17.1mGy 일반환자는 17.0mGy로 타병원 전원환자와 교통사고환자가 상대적으로 피폭이 많았다. 5. 방사선촬영 부위별로 보면 일반촬영에서는 두부피폭 1.7mGy로 사고환자에서 피폭이 많았고, 흉 부 2.0mGy, 복부 1.6mGy는 일반환자 에게 많았으며, 척추 3.4mGy, 골반부 1.8mGy, 상지부 0.5mGy, 하지부 0.6mGy는 교통사고 환자에게 피폭이 많았으며, 통계적으로 유의한 차이를 보였다 (P<0.001). 6. CT촬영에서는 타병원 및 전원환자가 두부 10.9mGy으로 많았고, 흉부와 복부는 각각 2.9mGy, 3.6mGy로 일반환자에게 많았고, 척추, 골반부 1,9mGy 2.7mGy는 교통사고환자에게 많았다. 특히 복부피폭은 통계적으로 유의한 차이를 보였다.(P<0.05) 결론적으로 한 대학병원 방문한 응급환자 특히 교통사고환자의 방사선 검사시 일반 외래 환자들의 촬영보다는 과다한 검사와 피폭이 노출선량한도가 2배 이상 증가하는 실정이다. 따라서 병원 관리자 및 방사선취급자는 환자 방사선 촬영시 노출을 최소한으로 제한하고, 방사선피폭감소를 위해 병원의 종 사자인 방사선사의 기술적인 연구와 및 보조연구자 및 의료인 등 모두가 예방할 수 있는 대책이 필요할 것으로 생각한다.
