        폐 색전증 증례 비교를 통한 혈전 용해제의 조기 투여 제언

        안효용,김신철,김명천,고영관 대한응급의학회 2000 대한응급의학회지 Vol.11 No.2

        Pulmonary embolism is a common condition with considerable morbidity and mortality. The diagnosis of pulmonary embolism remains a vexing problem. Prompt and accurate diagnosis is important because the mortality of untreated pulmonary embolism is high and serious complications can occur. Most physicians are inexperienced in the use of thrombolytic agents for pulmonary embolism, even though they utilize these agents routinely for acute myocardial infarction. We compared 2 domestic cases with 2 foreign cases. On comparison, we spent a long time in making a definite diagnosis in the domestic cases. Moreover, in the second domestic case, we did not use thrombolytic agents early, in spite of a suspected massive pulmonary embolism and then eventually he died. We conclude that bolus administration of thrombolytic agents during CPR for clinically suspected massive pulmonary embolism in emergency department may be an acceptable technique.

        인터넷을 이용한 One-Click 호출 시스템

        안효용,정성구,김명천,고영관 대한응급의학회 2000 대한응급의학회지 Vol.11 No.2

        Background: The time lag and the difficulty associated with calling clinicians of other departments are major concern in the emergency department(ED). We tried to design a new paging system which was faster, easier, and more accurate. Method: We made a web page comprised of paging numbers and then connected a personal computer in the ED to the internet through a dial-up moderm, via a web-paging service, and could page persons wearing public pagers. Results: We found that using the internet for paging was faster and more accurate than the hand-operated way. Calls were placed via the internet with only one click of the mouse. Conclusion: The One-click paging system is useful for hospital telecommunication. In this way, the internet can be applied to the entire emergency medical service system.

        Pacemaker-mediated Tachycardia 증례 보고 1례

        안효용,고영관 대한응급의학회 1999 대한응급의학회지 Vol.10 No.4

        Pacemaker-mediated tachycardia(PMT) is a circus movement tachycardia that can occur in patients with dual chamber pacemaker with atrial sensing(VDD or DDD), when a ventricular depolarization, either spontaneous or paced, causes retrograde activation of the atrium. Recently, a number of pacemaker manufactures have incorporated in their devices a variety of relatively complex algorithms to prevent PMT. Despite these measures, PMT may still occur because of inappropriate programming or unpredictable variations of ventriculoatrial conduction. We report one case of PMT in a 78-year-old male who received DDD type pacemaker due to sick sinus syndrome. In this case, PMT was disappeared after reprogramming parameters of pacemaker and the application of PMT protection algorithm.

        파상풍 환자의 치료1례

        김동필,원형섭,김명천,안효용,고영관 대한응급의학회 1998 대한응급의학회지 Vol.9 No.2

        Tetanus is a rare in the developed countries, including Korea as a result of nearly universal active immunization. Because many physicians have little experience with its diagnosis and management, misdiagnosis and therapeutic delay may result in catastrophic consequences. We report one case of generalized tetanus. A previously healthy 35-year-old man was admitted to the emergency department because of stiffness on jaw and neck board-like abdomen, extended and rigid both legs, chest tightness, and dyspnea. Seven days before admission, he was injured on the right thigh at work. In the emergency department, he was given 5,000 units of human tetanus immunoglobulin intramuscularly, as well as diazepam 2mg/hr intravenously. On the second hospital day, tracheostomy was performed. Ten days later, his condition was improved. Twenty eight days after admission, he was discharged without any complication.
