PURPOSE: This study was to examine the effects of supportive nursing care on surgical patients in the operating room. METHOD: This study was nonequivalent control group none-synchronized design. The data were collected during the period of July 26 through October 8, 1999 at K hospital in Kwangju. The subjects for the study were selected from those patients who were admitted to K hospital for abdominal surgery. Forty-eight adult subjects were selected and evenly divided into two groups: 24 for the experimental group and the other 24 for the control group, respectively. The tool used for measuring state and trait anxiety was the one originally worked out by Spilberger(1976), and translated by Kim Jung-Taek and Shin Dong-Kyun(1978) for suitable application for Koreans. Data were analyzed by x2-test, t-test, Chronbach's alpha coefficient using SAS/PC+. RESULT: Results were as follows: 1. The degree of State anxiety was found to be lower in the experimental group who received supportive nursing care in the operating room immediately before an operation than the control group who did not."(p<.001). 2.There was no significant difference on the post-test blood pressure and pulse rate immediately before operation between the two groups(p>.05). CONCLUSION: Results of the above study reveals that the supportive nursing care in the operating room is effective in alleviating the anxiety of patients. I suggest that it is highly desirable to apply supportive nursing care for those patients who are waiting for immediate surgery.

PURPOSE: Endothelin-1(ET-1) is a potent vasoconstrictor peptide. It has potent contractile and proliferative effects on vascular smooth muscle cells. Congenital heart diseases are often accompanied by pulmonary hypertension, and the severity of pulmonary hypertension is important in the prognosis. The aim of this study was to elucidate changes of ET-1 after pulmonary venous stenosis in a dog model, and investigate the interaction between pulmonary venous pressure and ET-1. METHODS: Plasma ET-1 levels were measured by radioimmuno-assay at the thoracic aorta, left pulmonary artery and left pulmonary vein. Pressures were also monitored at the same sites. Immunohistochemical staining of ET-1 was performed in the lung tissue. RESULTS: Increased serum ET-1 levels were noted at 1 hour after left pulmonary vein stenosis in the left pulmonary vein and aorta, and at 2 days after stenosis in the left pulmonary artery. Left pulmonary venous pressure was significantly increased at 1 hour after pulmonary vein stenosis, and systolic pulmonary artery pressure at 2 days after stenosis. Increased expression of ET-1 was noted by immunohistochemical staining at the lung tissue at 7 days after stenosis of left pulmonary vein. CONCLUSION: Increased serum ET-1 level and expression of ET-1 in immunohistochemical staining at lung tissue were noted after stenosis of pulmonary vein. Serum ET-1 level would be useful in the diagnosis and prediction of pulmonary artery hypertension. (J Korean Pediatr Soc 2000;43:769 778)

Pulmonary vein velocities have recently been estimated in conjunction with mitral flow velocities to increase our understanding o ventricular filling. The advent of transesophageal echocardiography with pulsed Doppler imaging capability has provided a method by which both the mitral valve and pulmonary vein velocities can be easily recorded because of the posterior approach providing unimpeded interrogation of cardiac structures. The purpose of this present study was to evaluate the normal pulmonary venous, mitral and aortic flow pattern by transthoracic echocardiography in neonate according to the postnatal age. The results were as follows. 1) With regard to the aortic flow, the early systolic was of pulmonary flow peaked after the onset of aortic flow and the late systolic wave occured consistently before aortic valve closure. 2) The peak velocities of early systolic, late systolic, late systolic, diastolic and atrial systolic in the pulmonary venous flow were 36.4 (13.2cm/sec, 45.3 (15.3cm/sec, 48.5 (14.1cm/sec and 16.6( 5.7cm/sec at 1 day old. the difference according to the postnatal age was not significant. 3) The ratio of peak systolic to peak distolic velocity of pulmonary venous flow was 1.0( 0.3 at 1 day o1, 1.1( 0.4 at 1 week old and 1.2 (0.3 at 1 month old. The difference between old and 1 month old was statistically significant(p<0.05). 4) The peak early diastolic velocity of mitral flow was 51.3 (15.2cm/sec at 1 day old, 54.7( 13.7cm/sec at 1 week old and 80.7 (16.6cm/sec at 1 month old. The difference between 1 week old and 1month old was statistically significant(p<0.01). 5) The peak late diastolic velocity of mitral flow was 48.3 (14.6cm/sec at 1 day old, 50.1( 9.9cm/sec at 1 week old and 71.8 (16.6cm/sec at 1 month old. The difference between 1 week old and 1 month old was statistically significant(p<0.01). 6) The ratio of peak mitral early diastolic to peak late diastolic velocity was 1.1( 0.2 at 1 day old, 1.1( 0.3 at 1 week old and 1.2( 0.7at 1 month old. The difference between 1 week old and 1 month old was statistically significant(p<0.01). 7) The peak aortic valve flow velocity was 62.1 (14.2cm/sec at 1 day old, 67.8 13.4cm/sec at 1 week old and 76.6 14.1cm/sec at 1 month old. The difference between old and 1 month old was statistically significant(p<0.05). In conclusion, improvement of left ventricular diastolic function was noted at 1 month old by echocardiography. These normal data will be useful in comprisons with the data, which obtained in newborn with various congenital heart disease that affects flow dynamics.

PURPOSE: The purpose of this study was to test the validity of a modified clinical performance examination (CPX) for preclinical students in nursing. METHOD: 70 nursing students in their second semester of the junior year at C University participated in CPX. Scenarios and checklists were developed by our research team from September to October 2005. Six stations were organized. Evaluation included physical examination of a patient with lung cancer, education on usage of a metered dosage inhaler, and lobectomy postoperative care. Students were randomly assigned to a station. RESULT: There was a difference in the CPX scores according to stations. The agreement of scoring between trained faculty members and SPs was more than moderate (r=.647). The correlation between the CPX score and the average grade in the previous semester and between the CPX score and the average grade of a paper and pen test of the pulmonary system of adults was low (r=.276; r=.048). CONCLUSION: Traditional CPX is generally recommended, however, modified CPX is appropriate for preclinical students in the current Korean Nursing school setting if there are additional scoring systems to balance the testing level at each station.

BACKGROUND: This study was conducted to explore the prevalence of and the factors affecting constipation in elementary school students in urban and rural areas. METHODS: Study subjects were 585 grade 5 and 6 students. We conducted self-administered questionnaires during October, 2009. Outcome measure was the prevalence of constipation evaluated by the Rome III Diagnostic criteria for functional constipation. Independent variables were gender, grade, residence, mother's employment status, self-rated health status, number of family members, bowel movement habit, and health behavior (nutrition, exercise, and stress). RESULTS: The multiple logistic regression analysis showed that females, grade 5 students, those with working mothers, and those physically inactive reported having constipation significantly more often. CONCLUSIONS: Our study revealed that the female gender, increasing age, mother's employment status, and physical inactivity were risk factors for constipation in elementary school students. To improve bowel function in children, health education programs and school health promotion programs targeting healthy life habits should be implemented.

A modern development of ambulatory ECG monitoring gave great advances in the diagnosis and evaluation of various cardiac conditions. Fifteen cases of ischemic heart disease, 11 cases of nonischemic heart disease, 5 cases of noncardiac disease and 9 cases of normal healthy subjects were studied from January 1980 to July 1981 in national Medical Center, with the following results: 1) The heart rate was decreased during night time, with less decreasing tendency in patients with ischemic heart disease. 2) Among 30 cases, including 12 patients with ischemic heart disease, who didn't show arrhythmia on routine 12 lead ECG, 12 cases, including 6 patients with ischemic heart disease, showed arrhythmia on Holter monitoring. 3) Among 5 cases with ischemic heart disease who showed premature ventricular contraction on day time monitoring, 2 cases didn't show premature ventricular contraction on nigh time monitoring. 4) The S-T segment and T wave were changed during night time in 2 cases with ischemic heart disease and in 2 normal subjects. From these results, we could assert that Holter monioring or ambulatory ECG tracing would be a good method for diagnosis and evaluation of ischemic heart disease, and other cardiac conditions. Several another studies with this equipment have to be performed and would give more distinctive outcomes.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) continues to be a major cause of nosocomial infection and a molecular typing is necessary for proper epidemiologic investigations of sources and moles of spread in an outbreak. An nosocomial outbreak of MRSA in a neonatal intensive care unit at Ewha Womans University Mokdong Hospital was suspected. To investigate the clonality of isolates and control the spread of nosocomial outbreak, we performed plasmid restriction analysis of MRSA isolates from patients and medical staffs. METHODS: We studied 7 MRSA strains (umbilicus 4, blood 1, urine 1 and pus 1) from patients in a neonatal intensive care unit and the MRSA strains from nares and hands surveillance cultures of 26 medical staffs (4 medical doctors and 22 nurses). All MRSA strains were tested for antimicrobial susceptibility and plasmic analysis after EcoRI restriction. We analyzed the plasmid patterns of MRSA isolated from patients and compared with those from medical staffs. RESULTS: Ten MRSA strains (from 7 nares and 3 hands) were isolated from surveillance cultures of 26 medical staffs. Seven out of 10 MRSA strains from medical staffs revealed identical pattern of antibiogram which was the same pattern in all 7 MRSA strains from seven patients. Plasmid restriction patterns were classified 6 groups from A to F showing 2-10 bands. Six out of 7 MRSA strains from the patients showed group A(A1 5, A31) and 5 out of 10 MRSA strains from the medical staffs showed group A(A1 1, A21, A32, A41) and remainders showed different plasmid restriction analysis patterns. CONCLUSIONS: These results suggest that plasmid restriction analysis is a rapid, inexpensive, and good discriminating molecular typing of MRSA outbreak and is useful for the epidemiologic investigation of MRSA outbreaks in the clinical laboratory.

PURPOSE: To evaluate the effects of respiration on diastolic filling pattern in normal children by Doppler echocardiography. MATERIALS AND METHODS: Doppler echocardiograms of the tricuspid and mitral valves were recorded with electrocardiogram and respirations in 46 normal children aged 3months to 14years(7.6+/-3.5year). We measured the following variables: heart rate, the peak E and A velocities, the area under the E and A portions of the diastolic velocity-time integral(VTI) isovolumetric relaxation time(IVRT). From these measurements, we calculated the following: the peak E/A ratio, the VTIe/VTIa, VTIe/VTIt, VTIa/VTIt. RESULTS: There was a significant decrease with inspiration only in peak E velocity of left ventricle(LV) filling. There was a significant increase in peak E velocity, peak A velocity, peak E/A, VTIe, VTIe/VTIa, VTIe/VTIt and VTIa/VTIt of right ventricle(RV) filling with inspiration. The LV peak E velocity, peak A velocities and VTIe were significantly higher than those of the right ventricle during inspiration. All variables of diastole except VTIa and VTIa/VTIt were higher for the left than for the right ventricle during expiration. VTIa/VTIt was higher for right ventricle. CONCLUSION: Assessment of pediatric RV and LV diastolic flow by echocardiography should include standardization for phase of respiration.
