This study was carried out to determine the effect of $-6^{\circ}$ head-down bedrest on the cardiovascular and hormonal responses to orthostasis and to evaluate the mechanism of orthostatic intolerance. Ten healthy young men were changed the body position from $-6^{\circ}$ head-down or supine bedrest for 2 hr to $70^{\circ}$ head-up tilt for 20 min. During the bedrest, there were no differences in hemodynamic and hormonal changes between the head-down and the supine positions. However, the tendency of decreased end-diastolic volume and increased cardiac contractility during the later period of 2 hr showed that the cardiovascular adaptation could be accelerated within a relatively short period in the head-down bedrest. During the head-up tilt, presyncopal signs were developed in five subjects of the supine bedrest, and one of the same subjects of the head-down bedrest. In the tolerant subjects, the increase in cardiac contractility and plasma epinephrine level during the bend-up tilt was greater following the head-down bedrest than that following the supine bedrest to compensate for reduced venous return. The intolerant subjects showed the greater decrease in end-diastolic and stroke volume, and the greater increase in heart rate during the head-up tilt than the tolerant subjects. Cardiac contractility and plasma epinephrine level were remarkably increased. However, arterial pressure was not maintained at the level for the appropriate compensation of the reduced venous return. It seems that the tolerance to orthostasis is more effective after the short-term head-down bedrest than after the supine bedrest, and the secretion of epinephrine induces the higher cardiac performance as a compensatory mechanism fur the reduced venous return during the orthostasis following the head-down bedrest than the supine bedrest.

Purpose: The purpose of this study was to investigate hemato-oncology patients' discomfort and bleeding in relation to the bedrest time after bone marrow examination. Methods: A descriptive correlational study was conducted. The data were collected using self- report questionnaire from total of 131 patients who underwent bone marrow examination from January 2017 to September 2017. Data were analyzed with descriptive statistics, Wilcoxon Signed-rank test, McNemar's test and logistic regression. Results: The level of discomfort after 4 hours of bedrest was significantly higher when compared to 2 hours of bedrest(p<.001). The occurrence of bleeding after 2 hours of bedrest was significantly higher than 4 hours of bedrest(p<.001), however the degree of bleeding was slight. No bleeding occurred in 84% of the patients after 2 hours of bedrest. Conclusion: The results of this study demonstrated that shortening the bed rest time after bone marrow examination was helpful in improving the patient's well-being. Bedrest time could be shortened according to the site of bone marrow examination and patient's condition.

The purpose of this study was to review the study design, participants, intervention and its outcomes of studies for post-dura puncture headache using systematic review. Total 4234 studies were searched from 1980 to 2016 years,15 studies were included in final. Total 5239 patients were participated in studies, and 10 RCTs studies and 5 observational studies were included. The findings showed that experimental studies used the 24hr bedrest intervention as a control group for comparing the prevalence of headache with the early ambulation intervention group. The prevalence of headache in ambulation group was lower than 24hr bedrest group (except 2 studies). The high risk methodological bias should be considered when understandings the research findings. Based on this study, meta-analysis study for investigating the proper period of time for bedrest should be performed in further study.

Objective: The aim of this research was to investigate the depressive effect of Sa-am Acupuncture(膀胱正格) in stroke patients. Methods: We measured the blood pressure of the patients who were admitted in the Oriental Medical hospital of Dae-Jeon University from June. 2003. to September. 2003. If systolic blood pressure was over 160mmHg or diastolic blood pressure was over 100 mmHg, 40 patients were treated by Sa-am Acupuncture(膀胱正格) and the other 20 patients were taken a rest in bed. Then 30 minutes and 60 minutes later, systolic, diastolic blood pressure were measured. Results: After 30 minute treatment, Sa-am Acupuncture(膀胱正格) significantly depressed the systolic and diastolic blood pressure, but bedrest can't do it. After 60 minute treatment, both Sa-am Acupuncture(膀胱正格) and bedrest significantly depressed the systolic and diastolic bood pressure. Conclusion: These results suggest that Sa-am Acupuncture(膀胱正格) is effective in depressing the systolic and diastolic blood pressure.

Purpose: The purpose of this study was to identify the effectiveness of back pain prevention intervention program on reducing back pain of patients undergoing percutaneous coronary intervention (PCI). Methods: The patients were divided into two groups as the experimental group and control group. In the experimental group, the participants took bedrest for 4 hours after PCI and then received back pain prevention intervention program (BPPIP). Total of 5 times BPPIP with 1 hour interval for 5-10 minutes per each intervention was administered to the patients taking bedrest for 4 hours after PCI. In the control group, total of 5 times routine nursing care with 1 hour interval was administered to the patients taking bedrest for 4 hours after PCI. The data were collected on admission in the ICU and after the 5 exercise sessions. The collected data were analyzed using SPSS/WIN program. Results: No significant differences in the occurrence of hemorrhage after the BPPIP were observed between the experimental group and the control group. After the BPPIP, back pain outcomes were significantly low in the experimental group. However, urination disorder and cortisol level did not show a statistically significant differences between two groups. Conclusion: It is clear that BPPIP is a useful nursing intervention for reducing back pain of patients undergoing PCI.

Purpose: The purpose of this study was to identify the effect of exercise therapy on low back pain, self-urination disorder, bleeding, and hematoma in Percutaneous Coronary Intervention (PCI) patients. Methods: A total of 64 PCI patients were recruited from C hospital located in C city, from June until August of 2010. The patients were divided into two groups as the exercise and control group. Thirty-two participants in the exercise group took bedrest for two hours after PCI, and then received excise therapy. The other 32 participants in the control group took the usual 8-hour bedrest with intermittent back care by the unit nurses. Results: In the relieving effect of low back pain, exercise group reported pain reduced faster than the control group. On the other hand, there were no significant differences between the two groups in alleviant of self-urination disorder, bleeding, and hematoma. Conclusion: Exercise therapy for reducing patients' low back pain showed to be an effective nursing intervention. Since there was no bleeding or hematoma after PCI in the exercise group, this study provided the ground suggesting that it might be possible to reduce the bedrest time after PCI without increased risk of bleeding or hematoma.

Background To date, there are no consensus guidelines for management of lymphatic leak in groin vascular reconstruction patients. The goal of this study is to review the relevant literature to determine alternatives for treatment and to design an evidence-based algorithm to minimize cost and morbidity and maximize efficacy. Methods A systematic review of the literature was conducted per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Two independent reviewers applied agreed-upon inclusion and exclusion criteria to eligible records. Studies that included patients who underwent groin dissection for oncologic diagnoses and level 5 data were excluded. Interventions were then categorized by efficacy using predetermined criteria. Results Our search yielded 333 records, of which eight studies were included. In four studies, the success of lymphatic ligation ranged from 75% to 100%, with average days to resolution ranging from 0 to 9. Conservative management in the form of elevation, compression, and bedrest may prolong time to resolution of lymphatic leak (14-24 days) and therefore cost. Conclusions The majority of patients should be offered early operative intervention in the form of lymphatic ligation with or without a primary muscle flap. If the patient is not an operative candidate, a trial of conservative management should be attempted before other nonsurgical interventions.

Objective : Cerebrospinal fluid leakage related complications (CLC) occasionally occur after intradural spinal surgery. We sought to investigate the effectiveness of early ambulation after intradural spinal surgery and analyze the risk factors for CLC. Methods : For this retrospective cohort study, we enrolled 314 patients who underwent intradural spinal surgery at a single institution. The early group contained 79 patients who started ambulation after 1 day of bedrest without position restrictions, while the late group consisted of 235 patients who started ambulation after at least 3 days of bed rest and were limited to the prone position after surgery. In the early group, Prolene 6-0 was used as the dura suture material, while black silk 5-0 was used as the dura suture material in the late group. Results : The overall incidence rate of CLC was 10.8%. Significant differences between the early and late groups were identified in the rate of CLC (2.5% vs. 13.6%), surgical repair required (1.3% vs. 7.7%), and length of hospital stay (2.99 vs. 9.29 days) (p<0.05). Logistic regression analysis revealed that CLC was associated with practices specific to the late group (p=0.011) and the revision surgery (p=0.022). Conclusion : Using Prolene 6-0 as a dura suture material for intradural spinal surgery resulted in lower CLC rates compared to black silk 5-0 sutures despite a shorter bed rest period. Our findings revealed that suture - needle ratio related to dura defect was the most critical factor for CLC. One-day ambulation after primary dura closure using Prolene 6-0 sutures appears to be a costeffective and safe strategy for intradural spinal surgery.

The purpose of this study was to investigate the correlation between the knowledge and educational needs related to recurrent in coronary artery bypass graft patients as a basis to provide an individual nursing education for the population. The subjects consisted of 110 patients who had coronary artery bypass graft(CABG) at Asan Medical Center in Seoul and Sechong hospital in Buchon. Data was obtained from a knowledge questionnaire and a learning needs questionnaire between November 1998 and February 1999. Data were analyzed using SAS program for Wilcoxon rank sum test and Spearman correlation coefficient. The results were as follows : 1. With regard to the 18 items to measure knowledge, the mean (median) of items 'don't know' was 4.9(4) items. The mean (median) of items answered wrong was 3.2(3) items. The number of items answered 'don't know' tend to show higher in those who had less education, blue color jobs and myocardiac infarction history than in their counter parts. There were higher frequency of items answered 'don't know' in those who had no hypertension 2. With regard to the level of knowledge by questionnaire about CABG, The most "I dont know" (59.1%) highly response was 'He has to be treated with anticoagulant drug to prevent revasculized vessel from obstructing.' The seond highest response (56.4%) was 'If you were hypotensive, the coronary attack would collapse. 'During the hospitalized day, the patient has complete bedrest.' The highest error probability was cholesterol has not to intake.', 'After surgery, the sexual life is need controlled for 1 year. 3. The mean of educational needs was 3.38. With regard to the level of learning needs by sentence about CABG, 'Food that benefit heart disease', 'Recurrence possibility of heart disease', 'Management method of operation site', 'Risk symptom that visit hospital or report immediately' were higher than other sentenses. With regard to the level of learning needs by factor 'food(5 items)', 'disease(9 items)' and 'exercise(3 items)' showed the highest than other factors. The educational needs by patients characteristics tend to show higher in males, under the age of 49, middle or high school degree, previous experience of admission with coronary artery disease, history of myocardial infarction, expierience of PTCA, history of cerebro-vascular accident, previous expierience of smoking than in their counter parts. 4. The number of items answered 'don't know', wrong and correct weren't correlated with the level educational needs. As the results, the number of items answered 'don't know' tend to show higher in those who had less educated, blue color jobs and myocardiac infarction history than in their counter parts. There were higher frequency of items answered 'don't know' in those who had no hypertension .There were higher frequency of items answered 'don't know' on anti-thrombolitic theraphy, hypotension and pain relief. Also there were higher frequency of items answered wrong on bed rest period, cholesterol intake, and sexual life. Educational needs were higher in young age group, had previous experience of procesure and history of other disease. And when we educate CABG patients, education for diet, recurrence possibility of disease, management methods of operation site and risk symptom should be emphasized.
