        In this study, to improve the marine bridge disaster prevention system, the trend of disaster accidents due to the extension of maritime bridges was analyzed and the status of domestic and foreign disaster prevention facilities was examined. As a result of the review, it was aimed at presenting the disaster prevention facility grade and installation items considering the size of the bridge and traffic volume.

        경동맥 내막절제술을 위한 마취관리

        김종훈,김선호,유선국,황경일,이승룡 대한마취과학회 1997 Korean Journal of Anesthesiology Vol.33 No.4

        We have experienced an anesthetic management of 56-year-old male patient with carotid stenosis. Carotid endarterectomy was performed with processed electroencephalography(compressed spectral array, CSA) monitoring. Carotid endarterectomy has significant risk of perioperative stroke and myocardial infarction. For brain protection during carotid cross clamp, body temperature of patient was maintained at 33.5oC and thiopental was infused continuously to induce burst suppression. To maintain blood pressure during cross clamp, dopamine was infused continuously and phenylephrine was injected intermittently. CSA was performed to monitor thiopental-induced burst suppression and ischemic brain insult. After releasing carotid cross clamp, body temperature was raised to 35oC.

        Meperidine 의 국소마취제적 특성이 심근 수축에 미치는 영향

        김종훈,김정섭,박윤곤,김승준 대한마취과학회 1998 Korean Journal of Anesthesiology Vol.34 No.2

        Background : The effects of various concentration (20, 50, 100 M) of meperidine were studied in isolated guinea pig and rat ventricular papillary muscles. Methods : Isometric force of guinea pig ventricular papillary muscle was examined in normal and 26 mM K Tyrode's solution. Experiments using rat and guinea pig papillary muscle under normal and low Na (40 mM), respectively, were performed to evaluate the effect on Ca2 release from the sarcoplasmic reticulum (SR). Normal and slow action potentials (APs) were evaluated by using conventional microelectrode technique. Rapid cooling contractures were performed. Results : Meperidine caused dose-dependent depression of peak force from rested-state (RS) to 3 Hz stimulation rates in guinea pig papillary muscles. Conduction block was frequently noted at high stimulation rates (2 and 3 Hz) at 150 M meperidine. ∼40% depression of peak force was shown at RS contraction under low Na Tyrode's solution, although contractile depression was not shown at RS and low stimulation rates in rat papillary muscles. 100 M naloxone did not reverse the contractile depression caused by 100 M meperidine. Either depression of dV/dt-max from 0.1 to 3 Hz stimulation rates or rate-dependent depression among 1, 2 and 3 Hz could be observed at 150 M meperidine. In 26 mM K Tyrode's solution, 50 and 100 M meperidine caused dose-dependent depression of early and late force development. In slow APs, changes of dV/dt-max were not shown at 100 M meperidine. ∼40% depression of contracture induced by rapid cooling following 2 Hz stimulation rates was shown at 100 M meperidine. Conclusion : The direct myocardial depressant effect of meperidine seems likely to be caused by local anesthetic properties of meperidine, not by the opioid action. Inhibition of SR Ca2 release, and decreased intracellular Ca2 secondary to Na channel blocking action of meperidine may at least in part be related to direct myocardial depression.

        상부위장관 대량 출혈을 동반한 Menetrier`s Disease 1예

        김종훈,이창환,이동근,이용철,안득수,김대곤,이수택,송하숙,황금만 대한소화기학회 1992 대한소화기학회지 Vol.24 No.4

        In Menetriers disease, the gastric mucasal hypertrophy is so great that the rugae looks like convolutions of the brain. Although this gross appearance is common to all cases of Menetriers disease, either the gastric glandular elements or the superficial epithelial elements may predominate; acid secretion may be high, normal, or low; and hypoproteinemia may or may not be present. There is no consensus about which of these features define the disease. The main abnormality is a remarkable hyperplasia of the mucous surface and foveolar cells, but its pathogenesis and pathophysiology are poorly understood. Menetrier's disease is rarely cited as a cause of hematemesis, although this complication is recognized and should be considered in any case of hematemesis in which rugal hypertrophy is found at gastrofiberscopy or upper gastrointestinal series (UGIS). Recently, we experienced a 37 year old man who presented with massive hematemesis and hypoproteinemia. Menetriers disease was suggested by laboratory findings, gastrofiberoscopy and UGIS. Massive UGI bleeding had repetitively occurred five times in spite of conservative management, so total gastrectomy was performed. The pathologic findings are consistent with those of Menetriess disease such as thickened hyperplastic mucosa of the gastric fundus with characteristic cystic dilatation of the deeper crypts. Thereafter, the patient have recovered in good general condition and UGI bleeding was stopped. We present a rare case of Menetries disease associated with masive UGI bleeding and a brief review of clinical and pathologic pictures and management.

        뇌동맥 임시겸자 위치에 따른 체성감각 유발전위 변화와 신경학적 손상의 차이

        김종훈,민경태,남용택,신용삼,김종엽 대한마취과학회 1999 Korean Journal of Anesthesiology Vol.36 No.4

        Background : Somatosensory evoked potentials (SSEPs) have been frequently used to monitor cerebral ischemia during cerebral aneurysm surgery. The relation of SSEP changes and postoperative neurologic deficits due to ischemia have been studied many times but the relation according to the location of temporary clips have not yet been evaluated. Methods : We studied 81 patients undergoing cerebral aneurysm surgery. Median nerve SSEP was used for temporary clipping of internal carotid artery (ICA) or middle cerebral artery (MCA) and posterior tibial nerve SSEP for temporary clipping of anterior cerebral artery (ACA). SSEPs were recorded after induction of anesthesia and dural opening (control value), during temporary clipping, and after relieving temporary clips. A change in cortical amplitude of more than 50%, as compared with control was considered as `significant'. The presence of significant SSEP changes and neurologic deficits according to the location of temporary clips were analyzed using 2 test. Results : Significant changes in M-SSEP were recognized in 7 of 31 patients of MCA clipping. 2 patients showed neurologic deficits in these 7 patients. Significant changes in M-SSEP were recognized in 7 of 26 patients of ICA clipping, but there was no neurologic deficit. Significant changes in P-SSEP were recognized in 4 of 24 patients of both ACAs clipping. Only 1 patient showed neurologic deficit, but SSEP change of this patient was insignificant. Temporary clip time was significantly prolonged if there were neurologic deficits. Conclusion : SSEPs may be able to be used to detect significant cerebral ischemia due to temporary clipping. Especially, M-SSEP was useful to detect cerebral ischemia due to MCA temporary clipping. (Korean J Anesthesiol 1999; 36: 660∼667)

        아트륨 빌딩에서의 사무실과 아트륨간의 화재확산에 관한 연구

        김종훈,이수경 한국산업안전학회 2000 한국안전학회지 Vol.15 No.2

        일반적으로 국내에서는 아트륨과 사무실 공간 사이를 내화구조로 하거나 방화셔터를 설치하고 있다. 그러나 선진외국에서는 이미 아트륨과 사무실 공간 사이에 유리벽을 설치할 수 있도록 하고 있다. 단, 유리벽면을 따라 방호용 스프링클러를 설치한다는 조건에서 이다. 본 연구는 이러한 문제점에 대하여 다음과 같이 진행하였다. 각 시나리오에 대하여 화재 시뮬레이션 프로그램인 FASTLite와 BREAK1을 사용하여 화재 전파 및 위험성을 분석하였다. 결과적으로 아트륨과 사무실간에는 아트륨의 규모가 크고 상부가 충분한 연기와 열기의 조정이 가능하고, 창문을 사이에 두고 일정간격으로 스프링클러 헤드를 설치하여 충분히 화재로부터 유리를 보호할 수 있는 경우 방화구획으로 인정 해주어야 할 것이다. 또한 충분한 연기와 열의 제어가 가능한 것이 공학적인 화재분석방법을 통해 인정받은 경우에는 아트륨과 주변 사무실간의 완전개방도 검토되어야 할 것이다. Generally, There is to install fire resist shutter or to compart between the office room and the atrium in the atrium buildings in Korea. But, Glass wall that is installed sprinkler which purpose to protect it from fire, is already installed between the office room and the atrium in the advanced nations. We study this problem as follow; We made the fire scenario, and analyze each scenario using FASTLite is fire modeling software and BREAK1 is to predict the window breakage time in the compartment fire. In this study, we can decide that fire compartmentalization between atrium and office rooms doesn't require in Atrium building if the material and fire protection system were reliable. Consequently, Korean Fire Protection Regulations have to consider in direction of increasing freedom of building.
