Purpose: It is crucial to provide adequate enteral nutrition for postoperative recovery, wound healing and normal growth in infants in pediatric cardiac ICUs. This study was done to develop a feeding protocol using the vaso-active inotropic (VAI) score and to evaluate the impact of nutritional outcomes following the new feeding protocol for infants who underwent cardiac surgery. Methods: This study consisted of three phases. First, a feeding protocol was developed based on a literature review. Second, ten experts rated the content validity. Third, a comparison study was conducted to evaluate the impact of the new feeding protocol. Data were analyzed using SPSS Version 20. Results: Twenty-nine infants were enrolled in the pre-protocol group, and 22 infants in the post-protocol group. Patients in the 2 groups were similar. Time to reach feeding goal was significantly decreased from 56.0 (27-210) hours to 28.5 (10-496) hours in the post-protocol group (Z=-4.22, p<.001). Level of enteral feeding knowledge among nurses increased significantly after implementation of the protocol. Conclusion: The feeding protocol using VAI score facilitates the achievement feeding goal to decrease feeding interruptions and help nurses in their practice. Larger studies are necessary to examine clinical outcomes following the implementation of this feeding protocol.

Purpose: The purpose of the study were to examine the nutritional status of severe brain injury adult patients in critical period, and to compare the nutritional states before and after tube feeding. Methods: Data from 19 patients admitted to the SICU in a university hospital due to severe brain injury were analyzed. Nutritional states were measured by anthropometric and blood biochemical indicators. Results: MAC and MAMC were significantly decreased only at 7 days after admission compared with those on the day of admission. TSF was significantly decreased from 7 days to 14 days after admission. Fat rate was significantly decreased from 3 days to 14 days after admission. Hb was significantly decreased only at 3 days after admission. Albumin was significantly decreased from 3 days to 14 days after admission. However, lymphocyte was significantly increased at 14 days after admission. TSF and Albumin became significantly worse even after initiating tube feeding. Conclusions: Nutritional status of severe brain injury patients in SICU became worse after admission whichever indicators were adopted to evaluate nutritional status, anthropometric or blood biochemical indicators, and became worse even after initiating tube feeding.

The nephrotic syndrome is characterized by generalized edema, hypoproteinemia(<2 g/dL), proteinuria(>40 $mg/m^2/hr$), and hypercholesterolemia(>200 mg/dL). It is reported that hypoalbuminemia, which is one of the four diagnostic criteria of the nephrotic syndrome, is associated with gallbladder wall thickening. An explanation for the thickened wall in hypoalbuminemic states is the accumulation of fluid in the subserosal layer of the gallbladder wall which contains the most areolar tissue. This report describes a patient who was initially diagnosed with the nephrotic syndrome at the age of 4 and subsequently developed acute acalculous cholecystitis at the age of 5.8 with an albumin level of 1.3 g/dL. The patient responded to fluid therapy, nasogastric suction, and broad spectrum antibiotics.

Surgical angioplasty of isolated stenosis of the left main coronary artery(LMCA) restores a more physiologic flow to the myocardium, allows percutdneous transluminal coronary angioplasty (PTCA) of distal coronary stenoses at a later stage, and is a less time consuming and convenient procedure than the conventional coronary artery bypass grafting(CABG) . Between Jul. 1994 and Dec. 1995, 7 surgical angioplasty had been performed. LMCA stenoses involved ostium in 2 patients, middle third in 3, and dis- tal third in 2. In 2 patients, the origin of left anterior descending coronary artery was involved in conjunction with LMCA. T e additional coronary artery stenoses were found in 2 cases. One patient was emergently operated after coronary angiography following his cardiac arrest. LMCA was approached anteriorly in all patients. The pulmonary artery was transected in 3 patients for a better exposure. The onlay patch consisted or autologous or bovine pericardium. There was no postoperative myocardial infarction or mortality. Left ventricular functions were well preserved in all patients. Postoperative coronary angiography revealed widely patent LMCA in 5 cases, and mild narrowing of distal anastomotic sites in 2 cases. Provided that well defined indications are followed correctly, surgical angioplasty can be a safe alternative to conventional CABG.

The objective of this study is to estimate the impacts of land cover change on the runoff behavior using Hydrologic Simulation Program-Fortran (HSPF) model and Landsat images. Land cover maps were prepared using three every ten years from 1980 to 2000 of the upper watershed ($258\;km^2$) of Gyeongan stream. Hydrologic parameters of HSPF were calibrated using observed data (1999 - 2000) and validated using observed data (2001, 2003) at Gyeongan gauge station. The simulation results showed that runoff volume and peak rate increased as $15.0\;km^2$ forest areas decreased and $19.3\;km^2$ urban areas increased for 20 years land use changes. The runoff volume showed a higher rate of increase in wet year (2003, 1709.4 mm) than in dry year (2001, 871.2 mm). The peak runoff increased $13.3\;\%$ in normal year (2000, 1257.3 mm) because the year has the highest rain intensity (241.3 mm/hr) among the test years. The runoff volume of a dry season and a wet season (May - September) in normal year 2000 increased $4.4\;\%$ and decreased $8.1\;\%$, respectively.

Purpose: This study was performed to test the clinical usefulness of the glucose test strip method for early detection of pulmonary aspiration in tube fed patients. Method: The subjects for the study were 36 patients who were receiving enteral feedings and 39 patients who were not given enteral feedings. For the analysis, the tube fed patients were divided into two groups (clinically significant aspiration and no aspiration) according to criteria. Result: The mean glucose concentration of tracheal secretions from non enteral fed patients was 26.35mg/dl and were lower than those concentrations found in tube fed patients (32.75mg/dl). The mean glucose concentration of the aspiration group was 45.60mg/dl and the glucose concentration of the non aspiration group was 19.93mg/dl. The difference was statistically significant (t=2.163, p=.038). More subjects in the no aspiration group ($73\%$) than the aspiration group ($56\%$) had glucose concentrations below 20mg/dl. After deleting the cases that had samples containing blood, glucose concentrations of tracheal aspirates were lower in both groups. Conclusion: The glucose level of the aspiration group was significantly lower than the no aspiration group and more subjects in the aspiration group had a glucose level higher than 101mg/dl. Therefore, the glucose test of tracheal secretions in tube fed patients could be a desirable test for screening for tracheal aspiration. Especially the patient who is showing repeatedly high glucose levels should not be given feedings until reassessment is completed.

Purpose: The purpose of this study was to develop a simulation module for teaching home health care and evaluate the applicability of the program to nursing students' practical training. Methods: The simulation module was developed based on the National League for Nursing Jeffries Simulation Theory. The theme of the developed scenario was teaching nasogastric tube feeding to the caregiver of patient with Parkinson disease. Participants were 61 nursing students who had learned tube feeding, and participated in the questionnaire survey after the simulation training. Results: The evaluation of simulation design showed the highest score on feedback/guided reflection, and was highly evaluated in the order of objectives/information, problem solving and fidelity. The educational practice of the simulation was highly evaluated in the order of active learning, high expectation and diversity of learning. The nursing students showed high satisfaction and self-confidence after the simulation education. Conclusion: We suggest that the developed simulation module can be applied to practical training for home health care. In the future, the change of self-efficacy, clinical judgment and performance ability of the students after the simulation education should be identified. Also, various simulation modules related to the community health nursing competencies should be continuously developed and verified.

Department of Internal Medicine, The Catholic University of Korea College of Medicine, Seoul, Korea Purpose: Malignant bowel obstruction causes gastrointestinal symptoms and leads to diminished quality of life in patients with advanced cancer. Several studies have shown the efficacy of octreotide for the relief of malignant bowel obstruction-related symptoms. The aim of this study is to assess the efficacy and safety of octreotide in patients with malignant bowel obstruction. Methods: We retrospectively reviewed medical records of twenty nine patients who had suffered from malignant bowel obstruction without clinical improvement of conservative care and subsequently, received octreotide treatment. Initial dosage of octreotide was 0.1 mg/day, and dose was escalated depending on the clinical effect. For each patient, we assessed visual analogue scale (VAS) of pain, number of vomiting episode, and amount of nasogastric tube drainage. Results: Median dosage of octreotide was 0.2 mg/day (range 0.1~0.6), and median duration from initial medication to death was 20 days (range 2~103). VAS before and after octreotide treatment were 5.6$\pm$1.24, and 2.7$\pm$0.96, respectively. The numbers of vomiting episode before and after octreotide treatment were 3.6/day$\pm$2.5, and 0.4/day$\pm$0.8, respectively. The mean amounts of nasogastric tube drainage before and after octreotide treatment were 975$\pm$1,083 cc/day and 115$\pm$196 cc/day, respectively. Statistically significant reduction in VAS, the number of vomiting episode and the amount of nasogastric tube drainage were observed after octreotide treatment (P<0.05). Conclusion: Administration of octreotide in patients with malignant bowel obstruction, which is uncontrolled by other medication, was effective and safe. In such clinical situations, physicians should consider to add of octreotide for symptomatic control.
