The purpose of this study was to identify the degree knowledge of myocardial infarction(MI) among the general population and to provide a direction for developing public health education programs. The subjects for this study were 187 people who lived in Seoul or Wonju City, Korea. The data were collected by questionnaire from Nov. ito Dec.5, 1997. The questionnaire was developed by the researcher based on a literature review, It consisted of 34 items of which nine items were on .iology, ten items on preventive measures, ten items signs & symptoms, five items on pain area. Analysis the data was done using descriptive statistics, t-test and ANOVA with the SPSS PC program. The results of the study are as follows: 1. The scores for knowledge of etiology(5.94), preventive measures(7.13), signs & symptoms(5.33) and area of pain(1.62). The highest score for knowledge about MI was preventive measures. the lowest score was for area of pain. Almost half of the subjects were not aware that 'hyperglycemia'and 'fatigue'can cause a MI. Also more than half of the subjects were not aware that 'reduced high carbohydrated diet'can prevent ML So this study showed that the general population has a need for more information about the relationship of hyperglycemia to MI. Less than half of the subjects knew that 'alteration in sleep pattern(49.4%)'. 'nausea, vomiting. indigestion(36.4%)''pain in the area of radiation and not in the chest(24.2%)' are sign & symptom of MI. Most of the people are aware that pain will be College of Nursing, Yonsei University Department of Nursing, Wonju College of Medicine. Yonsei University Department of Nursing. College of Medicine. Dankook University slightly to the left of the sternum(733%) but were not aware that pain may also radiate to the shoulder or arm(74.8%), neck or teeth(90.6%) Also 35% of the subjects think there is no treatment for an MI after it has occurred. 2. In the relationship between social demographic characteristics and degree of knowledge, there were significant differences due to sex, education level, and marital status. 3. This study showed hat most subjects got their in formation about MI from T.V. and radio(62.7%), but the score for knowledge was not high. The following are suggested based on the above results 1) It is necessary to reinforce information about signs & symptoms, area of pain and treatment of MI in public education programs, because people who do not know that their symptoms represent a heart at tack will delay seeking care and medical attention, 2) Because there are significant differences between knowledge and demographic characteristic(sex. education level, marital status), it is necessary to develop effective health education programs to consider these characteristics. Also we need behavioral strategies to change lifestyle and prevent more people from entering the MI high risk group. 3) Patients are almost always frightened and fearful which can cause a fatal delay. Education should focus on the emotional reasons behind people's resistance to calling the emergency medical system. 4) Educational programs need to target the potential witnesses rather than the individuals who suffer cardiac symptoms, focusing on the independent role that family members should take in the face of cardiac symptoms. Families of high risk group members, particularly their spouses, should receive special education about handling changes in cardiac symptoms. 5) Further studies are needed to identify factors which can cause patients to delay seeking treatment and to investigate the adaptive coping strategies of MI patients & their families when they have signs & symptoms.

BACKGROUND: In the clinical setting, for convenience of transfusion, blood is requested in advance, even though 'the type and screen' method has been used for the efficient supply of blood. We employed the precedent antibody screening test method for all patients who were scheduled for surgery, and compared the disposal rate and the clear rate pre and post-activity. METHODS: We evaluated the disposal rate and the cancellation ratio before and after employment of the precedent antibody screening test method for all patients expected to undergo surgery. A comparison of the frequency and type of side effects of transfusion was also performed. RESULTS: The disposal rate and the cancellation ratio showed a decrease, from 1.48% to 1.29%, and from 17.0% to 11.0%. No significant change was observed in the cause of disposal and the side effects of transfusion. CONCLUSION: Enforcement of a precedent antibody screening test resulted in a decrease in the disposal and clear rates. In addition, it aided in reduction of the amount of work performed at the blood bank by establishing the proper utilization of blood and reducing unnecessary cross match testing. There appears to be no problem regarding the stability of transfusion. However, for the sample showing a positive result on the antibody screening test, an effort to decrease the side effects of transfusion, such as exhaustive cross-matching and increasing the rate of identification, would be needed.

BACKGROUND: Hypercapnia augments cardiac output and can initiate a sympathetically mediated release of catecholamines to increase cardiac output. Many studies of hemodynamic changes by hypercapnia under general anesthesia with inhalation anesthetics besides sevoflurane. This study examined the hemodynamic changes by increasing end-tidal carbon dioxide (EtCO2) under sevoflurane-N2O anesthesia. METHODS: Twenty patients were enrolled in the study. We studied stable, mechanically ventilated patients under general anesthesia maintained with O2 2 L/min - N2O 2 L/min - sevoflurane (1.5-2.5 vol%). Hypercapnia were obtained by reducing tidal volume and respiratory rate. EtCO2 was adjusted to 30, 40, 50 mmHg with each concentration maintained for 15 min. Global hemodynamic variables were monitored with a pulmonary artery catheter. RESULTS: There were no changes in mean arterial pressure or heart rate by hypercapnia. Acute moderate hypercapnia increased cardiac output (4.9 +/- 1.7, 5.5 +/- 1.7, 6.2 +/- 2.1 L/min; P < 0.05), cardiac index (3.0 +/- 0.9, 3.4 +/- 0.9, 3.8 +/- 1.1 L/min/m2; P < 0.05), pulmonary artery pressure (16.9 +/- 3.7, 19.6 +/- 4.2, 23.0 +/- 4.7 mmHg), but did not decrease systemic vascular resistance (1,558.3 +/- 500.4, 1,423.5 +/- 678.6, 1,156.8 +/- 374.0 dynes.sec/cm5; P > 0.05). CONCLUSIONS: When we changed patient EtCO2 to 30, 40, and 50 mmHg, there were no changes in mean arterial blood pressure and heart rate, but systemic vascular resistance decreased, and cardiac output, cardiac index and mean pulmonary arterial pressure increased significantly.

PURPOSE: To investigate the causes, clinical features and characteristics of food-dependent exercise-induced anaphylaxis (FDEIA) in Korea. METHODS: A retrospective medical chart review was performed on the patients diagnosed with anaphylaxis between 2007 and 2011 in 14 hospitals in Korea. Cases with FDEIA were subsequently identified among anaphylaxis patients, and subgroup analyses were done to assess clinical characteristics of FDEIA. RESULTS: A total of 62 subjects with FDEIA (male, 72.6%; aged 16 to 70 years) were enrolled in 10 hospitals. Wheat (69.3%) was the most common cause of FDEIA, followed by meat (8.1%), seafood (6.5%), and vegetables (6.5%). The clinical manifestations were cutaneous (100%), respiratory (64.5%), cardiovascular (61.3%), and gastrointestinal (9.7%), respectively. In severity assessment, approximately 40% of FDEIA were classified as severe anaphylaxis. Portable epinephrine auto-injector was prescribed to 17.2% of patients, and about one fifth of the patients experienced redevelopment of anaphylactic symptoms during follow-up period. There was no significant difference of age, gender, latent period, total immunoglobulin E, and past history of allergic disease between patients with severe anaphylaxis group and patients with mild-to-moderate group. CONCLUSION: Wheat is the most common cause of FDEIA in Korea. Because significant number of patients with FDEIA experienced anaphylactic symptoms after diagnosis of FDEIA, more comprehensive therapeutic and educational approaches will be required to prevent recurrent development of anaphylaxis.
