Purpose: The purpose of this study was to evaluate a Self-efficacy-based Basic Life Support (SEBLS) program for high-risk patients' family caregivers on cardiac arrest. The SEBLS program was constructed on the basis of Bandura's self-efficacy resources as well as the International Liaison Committee on Resuscitation's '2000 Guidelines for CPR and ECC'. Method: The effect of the SEBLS program on emergency response self-efficacy and emergency response behavior such as BLS(Basic Life Support) knowledge and BLS skill performance was measured by a simulated control group pretest-posttest design. Study subjects were38 high-risk patients' family caregivers(20 experimental subjects and 18 control subjects) whose family patients were admitted to a general hospital in Incheon, Korea. Result: 1. Emergency response self-efficacy was significantly higher in the experimental subjects who participated in the SEBLS program than in the control subjects. (t=8.3102, p=0.0001). 2. For emergency response behavior, BLS knowledge (t=5.6941, p=0.0001) and BLS skill performance (t=27.8281, p=0.0001) was significantly higher in experimental subjects than in control subjects. Conclusion: A SEBLS program can increase emergency response self-efficacy and emergency response behavior, and could be an effective intervention for high-risk patient's family caregivers. Long-term additional studies are needed to determine the lasting effects of the program.

Hypothermic cardioplegia is a well established method to optimize myocardial preservation during ischemic arrest, and it has been demonstrated that oxygenation of crystalloid cardioplegic solutions markedly enhances myocardial protection, The addition of a small amount of red blood cells to a crystalloid cardioplegic solutions improves capillary perfusion. Considering these results, we changed our cardioplegic solution from cold oxygenated crystalloid[Group 2] to cold oxygenated diluted blood[Group 1]. In this investigation, we examined the effects of two hypothermic potassium cardioplegic solutions on myocardial preservation in 50 patients[30 of Group 1 and 20 of Group 2] of child age group. Factors considered preoperatively included age, sex, body weight, preoperative diagnosis, and they showed no statistical differences, Intraoperative factors considered included duration of cardiopulmonary bypass, duration of aortic occlusion, operative mortality, which also revealed no statistically significant differences, We measured the serum levels of GOT[glutamate oxaloacetate transaminase] and CPK [creatine phosphokinase] during the first two days postoperatively, which, in both groups, showed significantly higher values until postoperative 1 day, and decreasing tendancy thereafter, however we failed to find any significant difference between two groups regarding the serum levels of those enzymes each day. Time for extubation and use of inotropics also revealed no significant differences. Defibrillation was needed less in Group 1 than in Group 2[p<0.05], and one case of supraventricular tachyarrhythmia occured in Group l. We conclude that cold oxygenated diluted blood cardioplegia provides no less preservation than does an oxygenated crystalloid cardioplegic solution in child age group.

Use of ketamine and propofol combination (so-called Ketofol) anesthesiain a fixed ratio (1:1 mg/ml) was reported in dogs. The use of ketofol reduced cardiovascular suppression, but respiratory-related side effects was not significantly different from propofol alone. In this study, we evaluated the quality of ketofol anesthesia and changes in cardiopulmonary function according to the ratio of ketamine to propofol. The experimental groups were divided into three groups: propofol alone (P group), 3:7 ketofol group (PK1 group) and 1:1 ketofol group (PK2). For each group, the dose of 0.8 ml/kgwas administered intravenously at a constant rate until the tracheal intubation was possible and anesthesia was maintained with isoflurane for 120 minutes after induction of anesthesia. There was no significant difference in the anesthetic quality among three groups. Also, there was no difference in respiratory rate, tidal volume, end-tidal carbondioxide, and oxygen saturation. In group P, heart rate was not changed significantly during anesthesia, but arterial blood pressure decreased, while heart rate and arterial blood pressure increased significantly in group PK2. In the PK1 group, heart rate and arterial blood pressure during anesthesia remained similar to pre-anesthetic values. In conclusion, ketofol might be used as induction agent, and 3:7 ratioof ketofol showed more safe and effective anesthetic effect in dogs. Additionally, 1:1 ketofol may be used in patients with severe bradycardia orhypotension with close monitoring during anesthesia.

Purpose: This study was conducted to evaluate the effects of aerobic dance on physical functionnings of women with mastectomy. The study was single group pre- & post-test time series design. The aerobic dance program was performed three times a week for eight weeks, 45${\sim}$60 minutes per session. Method: The research variables used in the study were the period(seconds) of exercise that was taken for target heart rate, activity systolic pressure, range of motion of shoulder joint in affected side, and flexibility for physical functionnings. The data were analyzed with repeated measure ANOVA and Bonferroni multiple comparisons. Results: Over the period of aerobic dance, the degree of all the research variables were changed significantly, and also differed significantly every 2 to 4 weeks. The period(seconds) of exercise that was taken for target heart rate (p <.000), systolic pressure in exercise(p =.019), range of motions of shoulder joint on the affected side(flexion, abduction, over-adduction, over-extension, external & internal rotation), and flexibility(sit & reach, back & reach) (p= .003; p=.001; p(.001; p<.001; p= .014; p<.001; p=.036; p<.001) were differed significantly respectively. Conclusion: The results suggest that the aerobic dance program for women with mastectomy can improve and recover cardiopulmonary endurance and ROM of shoulder joint and that the period of exercise had to be performed over six to eight weeks and three times a week at least.

My prior questionnaire has applied to 12 male and 29 female adults over 30-69 years old suffering from lumbago fer 6 months at least or having diagnosis of lumbago. I had the following conclusions from physical characteristics and cardiopulmonary capacity of lumbago Patients caused by obesity 1) The rate of lipids in the body was rotated to the maximum heart rate in the male group of lumbago patients (P<0.01). 2) The rate of lipids in the body was related to the maximum intake of oxygen(O2) in the male group of lumbago patients(P<0.01). 3) The maximum heart rae was related to the maximum intake of oxygen in the male group of lumbago patients(P<0.01). 4) The rate of lipids in the body was related to the maximum intake of oxygen in the female group of lumbago patients(P<0.05). 5) The rate of lipids in the body showed no relation to the maximum heart rate in the female group of lumbago patients(P>0.05). 6) The maximum heart rate was related to the maximum intake of oxygen in the female group of lumbago patients(P<0.01). 7) The cardiovascular system showed no relation te the function of the lungs in the male and female groups of lumbago patients(P>0.05) 8) The lung capacity per second of lumbago patients(FEV $1.0\%$) measured less than normal adults. 9) The maximum intake of oxygen(V02max) and heart rate was less than normal adults. Thus I summarized the conclusion so follows: the cardiovascular system of lumbago patients showed no relation to their pulmonary function, and the rate of lipids in the body Showed a correlation with the maximum intake of oxygen but the rate of lipids in the body showed no relation to their pulmonary function.

Purpose: This study investigated the effects of home-based exercise intensity on the aerobic capacity and 1 year re-hospitalization rate in patients with chronic heart failure (CHF). Methods: Forty seven patients with CHF (males 33, females 14, age $61.3{\pm}9.8years$) participated in this study. The patients were allocated randomly to 3 groups in accordance with home-based exercise intensity: no home based exercise (NHE, 40%, n=19), moderate intensity home-based exercise (MIHE, 43%, n=20), and high intensity home based exercise (HIHE, 17%, n=8). All patients completed the symptom-limited cardiopulmonary exercise (CPX) test safely at the cardiac rehabilitation hospital. Results: The NHE group significantly showed lower peak $VO_2$ and a higher $VE/VCO_2$ slope than the MIHE (p<0.05) and HIHE (p<0.01) groups. On the other hand, the NHE group did not show significant differences in the other hemodynamic responses, such as heart rate (HR) max, HR reserve, maximal systolic blood pressure (SBP), and SBP reserve. Nine out of 19 NHE patients (47%) were re-hospitalized related to heart disease and two out of 20 MIHE (10%) patients were re-hospitalized, but nobody in the HIHE group were re-hospitalized within 1 year from the CPX test. Conclusion: In patients with CHF, home-based self-exercise is one of the important factors for reducing the re-hospitalization rate. In addition, improved aerobic capacity is strongly associated with a lower re-hospitalization rate. In particular, re-hospitalized CHF patients showed significant differences in respiratory parameters and hemodynamic parameters compared to the non-re-hospitalized patients.

Purpose: For cardiovascular patients, family caregivers play a vital role in daily nursing and cardiac emergencies. This study aimed to evaluate the effect of patient-centered CPR education (PCE) for family caregivers of patients with cardiovascular diseases. Methods: Fifty-four participants were randomly assigned to the PCE or control group. The PCE group received tailored counseling on overall cardiovascular disease information and CPR followed by interactive instructor-guided CPR training and re-education follow-up by telephone 2 weeks later. The control group received only video-based CPR self-education and booklets. Cardiovascular disease and CPR knowledge and self-efficacy were measured before (pre-test), immediately after (post-test 1), and 4 weeks after the PCE (post-test 2). CPR skills and performance were measured pre-test and at post-test1. Results: The PCE group demonstrated significant improvements in knowledge (F=91.09, p<.001), self-efficacy (F=15.19, p<.001) and CPR skills and performance (F=8.10, p=.008), as well as significant differences over time (knowledge: F=364.25, p<.001; self-efficacy: F=1162.28, p<.001; CPR skills and performance: F=1798.81, p<.001). There were significant group-by-time interactions for knowledge (F=8.10, p=.001), self-efficacy (F=4.30, p =.019) and CPR skills and performance (F=4.81, p=.036) by repeated measures ANOVA. Conclusion: This is the first study to demonstrate the effects of a patient-centered intervention with CPR education tailored for patients' and family caregivers' preferences, needs, and lifestyles. The results of this study encourage the use of tailored, patient-centered interventions in cardiovascular nursing practice.

Purpose: The purpose of this study was to develop an assistant device for the promotion of bag-valve-mask ventilation based on a non-equivalent control group pre-test and post-test design. Methods: The experimental tool was a mask assistance device developed by the researchers. Data were analyzed using SPSS 21.0 with the cardiopulmonary resuscitation (CPR) evaluation program from August 18 to 30, 2016. The research tools included general, hand-related, and ventilation-related characteristics. Results: Before and after using the mask assistance device, the tidal volume increased by 64 mL (p<.001) from 461.76 mL to 525.86 mL. The tidal volume for control was 477.86 mL, and there was a statistical difference (p<.05). The ventilation frequency in device users was 10 times per minute for a total of 20 ventilations with before 10.65 after 10 times, and that of the control group was before 10.36 times after 10 times; there was no difference in both groups(p>.05). The accuracy of the assistance device was $81.72{\pm}30.86%$, which was a very high value. However, the accuracy of ventilation in the control group with no assistance device was $18.97{\pm}32.44%$, which was a very low accuracy rate. Conclusion: This study's results suggested utilizing the newly-developed mask assistance device in CPR, and showed increases in tidal volume and accuracy of ventilation using the bag-valve-mask ventilation equipment. The general and hand-related characteristics did not have any effect, so the use of the device proved to increase the efficacy in all users.

배경: 헤파린표면처리 도관(Heparin-coated circuit: HCC)이 도관과 혈액사이의 반응(Blood-marterial reaction)을 줄여주어서 보체활성화(complement activation), 백혈구활성화(leukocyte activation)와 사이토킨 분비(cytokinerelease)등을 감소시켜 준다. 그러나 HCC가 수술 후에 출혈 양을 줄여주고 헌혈 필요량을 감소시켜 준다는 임상적 효과에 대해서는 인정된 부분이 많으나 아직까지 그 기전은 대부분은 미지의 상태로 남아있는 것이 사실이다. 본 연구는 HCC를 사용한 군(Group H)과 사용하지 않은 군(Group C)간에 심폐기 사용기간(Pumptime), 활성화 응고시간(activated clotting time: ACT)과 헤파린 사용량을 비교 분석해 봄으로서 두 군간에 존재할 수 있는 헤파린 사용량을 비교 분석해 본으로서 두 군간에 존재할 수 있는 헤파린 사용량 차이에 대하여 알아보려고 하게되었다. 대상 및 방법: 본원에서 1999년 5월 1일부터 동년 12월 31일 사이에 연령이 16세 이상인 환자에서 HCC를 사용했던 16명(Group H)과 사용하지 않았던 19명(Group C)을 대상으로 하였다. 모든 환자에서 수술 전 체중, 신장, 체표면적, 심폐기 사용시간(pumptime), 수술 중 최저체온, 대동맥 차단시간(Aortic cross clamping time. ACC time), ACT, 헤파린 및 프로타민 사용 양 등을 조사하였다. 결과: 연구대상 환자의 연령, 체중, 신장, 체표면적, 대동맥차단 시간, 체온 등은 HCC를 사용한 군(H 군)과 사용하지 않은 군(C군)간에 의미 있는 차이가 없었다(p<0.05). 헤파린 공급 전, 공급 후 20분, 40분, 60분과 프로타민 공급 후 20분에 측정한 ACT는 두 군간에 의미 있는 차이가 없었다. 두 군간의 처음에 공급한 헤파린 양과 총 프로타민 사용량은 차이가 없었으나(p>0.05), 추가 공급한 헤파린 양(11$\pm$30 versus 67$\pm$49mg, p<0.05)과 총 헤파린 사용량(176$\pm$44 versus 239$\pm$70mg, p<0.05)은 H군에서 의미 있게 적게 나왔다. 두 군간에서 심폐기 사용시간에는 차이가 없었으면서 H군에서 약 38%정도의 헤파린을 적게 사용하였다. 결론: 결론적으로 HCC의 사용으로 심폐기 사용 시간과 상관없이 추가하는 헤파린 양을 줄임으로서 총 헤파린 사용량을 줄여 줄 수 있었으며 이것이 HCC의 임상적 효과를 나타나게 하는 하나의 요소로 작용할 수 있다고 생각된다.
