Spontaneous subarachnoid hemorrhage(SAH) is a cause of high mortality and morbidity in the emergency department. Rebleeding has been well investigated, and it is now recognized that early operation can prevent rebleeding. However, ultra-early rebleeding, which may occur prior to early operation(within 24 hours after admission), worsens the clinical outcome of patients with SAH. To determine the risk factors of ultra-early rebleeding in patients with spontaneous SAH before early operation, we analyzed the cases of 383 patients admitted within 24 hours after their last attack of SAH between 1994 to 1996. In this analysis, diagnosis of rebleeding before admission was defined only if the patients experienced a definite clinical deterioration once more after an attack suggesting SAH. After admission patients who observed a sudden neurological deterioration were subject to repeat CT scanning and rebleeding was diagnosed only when new hemorrhage was observed on the CT scan in comparison with the previous scan. 45 cases(11.7%) of 383 patients had ultra-early rebleeding. The incidence of ultra-early rebleeding significantly increased in the patients who admitted hospital within 2 hours after attack. The incidence of ultra-early rebleeding also increased in the old-age group(70 years or more), patients with high systolic blood pressure, those who underwent angiography within 6 hours of the last SAH, and patients who had poor neurological condition.

Journal of the Korean Society of Emergency Medicine 1999;10(1):78-84
BACKGROUND: Headache is a common symptom. It has not proved useful methods that the physician evaluated the alert patient who had headache. It needs the presence of predictors of intracranial pathology(ICP) which serves as influential factors in the indication of evaluation and hospitalization of patients. METHOD: So, in order to identify such factors, patient records were retrospectively analysed. 168 patients with the chief complaint of headache presented to the Emergency Department of Chonnam University Hospital during the period from January 1, 1995 to December 31, 1997. All were in an alert mental state and had no evidence of trauma and intoxication. RESULTS: 14 cases(8.3% revealed ICP. 41 cases(24.4% revealed systemic disease. The remainder of cases were divided among unclassified headaches(61 cases, 36.3%, tension headaches(30 cases, 17.9%, and migraine(22 cases, 13.1%. Comparison of ICP-positive and ICP-positive cases revealed that ICP-Positive Patients could be categorized by the following findings: (1) Presence of the focal sign through neurological examination, (2) age greater than 55 years, (3) presence of associated symptoms, (4) acute headache. These four manifestations were proven to be statistically significant as predictors of ICP. CONCLUSION: Although the positive predictive value of the above criteria is not perfect for the prediction of ICP, they are worthy of clinical consideration in alert patients presenting with headache.

Journal of the Korean Society of Emergency Medicine 2000;11(1):35-43
BACKGROUND: Although diagnostic peritoneal lavage (DPL) is a well-established, reliably objective method of diagnosis of intraperitoneal injury, it is too sensitive to be used as a absolute indicator for emergency laparotomy. Recently, Otomo et al, have devised a new DPL criteria specifically designed and modified the classics criteria to aid in diagnosis of intestinal injury. So the author studied the difference of diagnostic sensitivity, specificity, and accuracy between the new and classic criteria for intestinal injury. METHODS: The author reviewed retrospectively one hundred fifteen patients underwent DPL from January 1993 to August 1999. The author adopted the classic criteria positive for intestinal injury when the lavage fluid was white blood cell(WBC) > or = 500/mm3 and newly developed supplementary criteria positive when RBC > or = 100,000/mm3, the positive-negative borderline was adjusted to WBC > or = RBC/150, and when RBC <100,000/mm3, to WBC > or = 500/mm3. And analyzed the difference of sensitivity, specificity, and accuracy each other. RESULTS: Among 115 patients, the sensitivity, specificity, and accuracy for intestinal injury were 96.4%, 87.4%, and 89.6% for the new criteria, and 100%, 42.5%, and 56.5% for the classic criteria. After exclusion of 10 patients in whom-DPL was performed within 3 hours or after 18 hours from the time of injury, the sensitivity, specificity and accuracy for intestinal injury were 96.4%, 97.4%, and 97.1% for the new criteria, and 100%, 46.8%, and 61% for the classic criteria. When analyzed the time interval from injury to DPL in the new criteria, 105 patients that DPL was performed between 3 to 18 hours had 2 false-positive, while 115 patients regardless of DPL time 11 false-positive. CONCLUSIONS : The author concluded that the new criteria of DPL effluent performed between 3 to 18 hours from abdominal blunt trauma would be more specific and accurate indicator of intestinal perforation than the classic criteria. And this new criteria will be used as a reliable indicator for emergency laparotomy for that patients.

Journal of the Korean Society of Emergency Medicine 1997;8(1):87-92
A standardized approch to serious head injury employing immediate CT scanning and aggressive medical and surgical therapy has improved outcomes in cases of intracranial lesions. Unfortunately, there is less agreement on how patients with mild head injury should be handled when first seen in an emergency department setting. The ideal policy in mild head injury would be diagnosis or rule-out intracranial lesions as quickly as possible. We reviewed the records of 126 mild head injury patients admitted during 6-month period to the Chonnam University Hospital to identify a group of mild head injury patients having lesions on brain CT scanning and to investigate the risk factors affecting abnormal lesions on brain CT scanning. All patients had alert mental status without neurological deficit and signs of skull fracture. Routine brain CT scans were obtained on all patients. Fifteen patients(12%) had 17 lesions on brain CT scans. Three patients needed surgery for their intracranial lesions. The initial Glasgow Coma Scale(GCS) was 15 in 107 patients and 14 in 19 patients. The incidence of abnormal brain CT lesions for each GCS was 9% in 15 and 26% in 14. The common symptoms of patients who had abnormal brain CT lesions was headache in 7(47%) cases, loss of consciousness in 7(47%) cases, amnesia in 4(27%) cases, dizziness in 4(27%) cases, vomiting in 3(20%) cases, and lethargy in 3(20%) cases. These data suggest that early brain CT scanning is necessary in alert patients who have GCS in 14, headache loss of consciousness, amnesia, dizziness, vomiting, or lethargy following mild head injury.

BACKGROUND: ST segment elevation in patient with chest pain was seen in acute myocardial infarction and in numerous other non-infarction syndrome. The causes of non-infarction syndrome were left ventricular hypertrophy, BER(benign early repolarization), and left bundle branch block in cardiac origin and were hyperkalemia and hyperventilation syndrome in metabolic origin and were others. Furthermore, the differentiation of electrocardiogram between acute myocardial infarction and non-infarction syndrome was very difficult. So, we compared and analysed characteristics of ST segment elevation of acute myocardial infarction and non-infarction syndrome that suggested the clue of early diagnosis of coronary artery disease. METHOD AND MATERIALS: We retrospectively reviewed the electrocardiogram of 961 patients with chest pain who visited the emergency center from January 1999 to December 1999. Acute myocardial infarction was diagnosed by clinical finding, electrocardiogram, cardiac enzyme, echocardiogram, and myocardial spect. Left ventricular hypertrophy, BER, and left bundle branch block in cardiac origin of non-infarction syndrome were diagnosed by electrocardiographic criteria suggested by William J. Brady. Acute myocarditis, acute pericarditis, and hyperventilation syndrome were diagnosed by clinical finding. RESULTS: Among 961 patients with chest pain, 236(24.6%) patients manifested ST segment elevation who were diagnosed acute myocardial infarction in 162(68.6%) patients and non-infarction syndrome in 74(31.4%) patients. The causes of non-infarction syndrome in 74 patients were left ventricular hypertrophy(32:13.6%), BER(28:11.9%), left bundle branch block(11:4.7%), and others(3:1.3%). Three others were acute myocarditis, acute pericarditis, and hyperventilation syndrome. Electrocardiographic characteristics of ST segment elevation of non-infarction syndrome manifested almost same finding compared to William J. Brady' criteria. CONCLUSION: ST segment elevation in patient with chest with chest pain visited emergency department was seen in acute myocardial infarction(68.6%) and the other non-infarction syndromes(31.4%). Significant number of patients were not associated with acute myocardial infarction. Therefore, we must completely understand characteristics of ST segment elevation in acute myocardial infarction and the other non-infarction syndromes to diagnose fatal early coronary artery disease and to avoid unnecessary thrombolytic therapy.

A spontaneous tension hemothorax due to the rupture of an intercostal artery aneurysm is a rare complication of type I neurofibromatosis. Until now, around 23 cases have been reported. The patient reported here presented with a spontaneous tension hemothorax. At the emergency department, we were faced with a rapidly aggravating hemodynamic compromise after chest tubing. An emergent thoracotomy revealed an actively bleeding huge intercostal artery aneurysm. We intended primarily to repair the bleeding aneurysm, but we failed with because of vascular fragility. Thus we present this case to share our terrible experience to other physicians.

The reliability of emergency ultrasonographic(US) detection of hemoperitoneum and solid organ injury in blunt abdominal trauma was evaluated retrospectively. From October 1,1995 to August 31,1996,90 patients were included in the study. Ultra- sonographic findings showed a sensitivity, specificity, and accuracy of 97.6%, 97.9%, and 98.1%, respectively, in detecting intraabdominal fluid collection. We believe that US in an emergency center is a quick, safe screening method in the evaluation of blunt abdominal trauma. In our department, US has replaced diagnostic peritonaeal lavage(DPL) and computed tomography(CT) as the screening study of first choice.

BACKGROUND: More than 90% of acute stroke patients have measurable cardiovascular sequelae, but we have been often overlooked in formal discussions of treatment. If we estimate the incidence of myocardial injury in patient with spontaneous SAH, we may figure the possibility of cardiac dysfunction in such patients. This study was designed to investigate the incidence of myocardial injury in patients with spontaneous SAH using cardiac troponin I(cTnI). METHODS: A prospective single emergency center study was performed to determined preoperative incidence of unrecognized cardiac injury in patients suffering spontaneous SAH. We include the spontaneous SAH patients who underwent serum measurements of the cardic troponin I immediately upon admission last six month period. ECG, CK, CK-MB and myoglobin were also performed at admission. We excluded the spontaneous SAH patients who had past history of myocardial ischemia and ECG abnormality. RESULTS: Fifty-two patients(34 females, 18 males) with spontaneous SAH were studied prospectively. 18 patients(34.6% of the total study population) had cTnI level above 0.5ng/ml. ECG was performed in 52 patients and was abnormal in 15 of the 52 patients(28.8%). CONCLUSION: The measurement of cTnI has provided physicians with a myocardial marker that has a cardiac sensitivity for cardiac injury equal to that of CK-MB yet with greater specificity. So, cardiac troponin I is useful to estimate the incidence of myocardial injury in patients with spontaneous SAH. And we may estimate the possibility of cardiac dysfunction in such patients. This knowledge will hopefully aid in the care and improve the outcome.

Journal of the Korean Society of Emergency Medicine 2008;19(4):349-358
PURPOSE: Rural emergency medical service (EMS) is inferior to urban EMS. In creating and providing emergency patient care, in rural areas, it is important to consider resources, patient volumes, geography, technology challenges, volunteer and provider issues, medical oversight, polities, education, communications, and financial concerns. In the current environment in Korea, it is necessary to design tailored and self-supporting rural EMS systems. For the development of a self-supporting model for EMS systems in rural areas, we have studied the EMS system in one rural area, Goheung County. METHODS: We obtained data from a health institute center, the Gwangju emergency medical information center, three emergency medical centers, and the fire station in Goheung county. In order to survey resident's perceptions about the local EMS system, we provided a questionnaire to 324 residents in Goheung County in March 2005. The advisory council for the EMS system analyzed problems at each step or component of the EMS service delivery process and suggested a model for self-supporting EMS service in Goheung County. RESULTS: The status of the EMS system in Goheung County is inferior to urban systems. A lack of appropriately trained emergency personnel at every level of care has been identified in this area. It is hard to find public education programs. There are few communication systems available for emergency medical care and there are extended transport times and distance, both for responding to and transporting patients. Resident's perceptions of the EMS system is unfavorable. The advisory council suggested an optimized plan to address the problems of the EMS system in Goheung County. A self-supporting model is suggested by the council. It is necessary to consider residents' participation and to apply available resources in Goheung County. CONCLUSION: An ideal EMS system in Goheung County will be a self-supporting model requiring participation of residents and wise application of available sources. The first consideration in this model is institution of a public education program and recruitment and education of first responders in every village is suggested. The model recommends integration of the EMS communication system to provide quality emergency medical care.

Bilateral diaphragmatic paralysis(BDP) is a rare disorder, which can be secondary to spinal cord injury, motor neuron disease, myopathy, noninfectious polyneuropathy, infection, iced saline cardioplegia performed during cardiac surgery, or idiopathic causes. there may be typical presentations such as dyspnea, paradoxical respiratory movement, and hypercapnic respiratory failure. It needs to exclude above secondary causes to consider idiopathic bilateral diaphragmatic paralysis. We report a 51-years-old man who presented with idiopathic bilateral diaphragmatic paralysis combined with acute pancreatitis. We couldnt, find out the association of these two clinical conditions. The patient was improved by mechanical ventilation.
