Vasoplegic syndrome은 심장 수술 후 $8{\sim}10%$의 빈도로 발생하고, nitric oxide와 guanylate cyclase가 중요 역할을 하는 염증반응에 유도함에 기인하며, 높은 사망률과 유병률을 나타낸다. 본 증례에서는 수술 전 패혈증이 있던 환자에서 심폐순환 후 vasoplegenic syndrome이 발생하였다. Gguanylate cyclase 억제제인 메틸렌 블루(MB)를 투여하여 환자는 즉시 호전을 보였으며 어떠한 혈압수축제의 도움 없이도 적절한 혈압을 유지할 수 있었기에 보고한다.

8주 동안의 목표심박수를 이용한 자전거 운동으로 심폐기능의 향상을 확인 하였다. 안정 시 수축기 혈압은 2.98% 감소하였으며, THBI는 7.59% 감소함을 확인하였다. $VO_2$ max는 24.60%, PTT는 4.92% 증가하였다. $VO_2$ max의 증가는 심장근의 발달로 1회 박출량의 증가를 나타내며, 1회 박출량의 증가는 심박수의 감소를 유도한다. 또한 많은 양의 혈액이 혈관에 공급되었으나 혈압이 감소하였다. 그 이유가 혈관의 탄성 증가에 의한 현상임을 PTT를 통하여 확인 하였다. 따라서 목표심박수를 이용한 운동은 건강관리에 큰 도움이 될 것이다.

The purpose of this study is to develop and evaluate the Self Efficacy Promotion and Exercise Program to prevent of obesity and cardiovascular diseases for the kidney transplant recipients. The subjects were selected randomly among the patients who underwent kidney transplantations at one major transplantation hospital in Seoul, Korea. This study ws carried out between November 23, 1999 and February 15, 2000. The subjects in this study consisted of 16 patients who had kidney transplantations between 1 month and 12 months ago prior to this study. They were all on steroids therapy and did not take any physical exercise regularly. The subjects received the self efficacy promotion and exercise program for 12 weeks which contained self efficacy promotion education and exercise program. The weight, body fat rate, exercise time and cardiopulmonary function were evaluated before the experiment and after the experiment. The results were as follows: 1. After the experiment, the weight was significantly decreased than that of before the experiment(p=.0001). 2. After the experiment, the body fat rate was significantly decreased than that of before the experiment(p=.0010). 3. After the experiment, the exercise time was significantly increased than that of before the experiment(p=.0002). 4. After the experiment, the absolute VO2 was significantly increased than that of before the experiment(p=.0008). 5. After the experiment, the relative VO2 was significantly increased than that of before the experiment(p=.0002). This study showed that the self efficacy promotion and exercise program was effective. So it would be expected that this self efficacy promotion and exercise program could be applied as an effective independent nursing intervention widely in prevention of obesity and cardiovascular diseases for kidney transplant recipients.

Objective: Cardiac dysfunction after aneurysmal subarachnoid hemorrhage (SAH) is associated with elevation of serum cardiac troponin I (cTnl) levels. Elevation of cTnl predicts cardiopulmonary and neurological complications, and poor outcome. Methods: We retrospectively reviewed the medical and radiologic records of 114 (male: 30, female: 84) patients who developed aneurysmal SAH between January 2006 and June 2007 and had no history of previous cardiac problems. We evaluated their electrocardiography and cTnl level, which had been measured at admission. A cTnl level above 0.5 $\mu$g/L was defined as an indicator of cardiac injury following SAH. We examined various clinical factors for their association with cTnl elevation and analyzed data using chi-square test, t-test and logistic regression test with SPSS version 12.0. The results were considered significant at p< 0.05. Results: The following parameters shows a correlation with cTnl elevation: higher Hunt-Hess (H-H) grade (p = 0.000), poor Glasgow Outcome Scale (GOS) score (p = 0.000), profound pulmonary complication (p = 0.043), higher heart rate during initial three days following SAH (p = 0.029), ruptured aneurysm on communicating segment of internal carotid artery (p = 0.025), incidence of vasospasm (p = 0.421), and duration of hyperdynamic therapy for vasospasm (p = 0.292). A significant determinants for outcome were cTnl elevation (p = 0.046) and H-H grade (p = 0.000) in a multivariate study. Conclusion: A cTnl is a good indicator for cardiopulmonary and neurologic complications and outcome following SAH. Consideration of variable clinical factors that related with cTnl elevation may be useful tactics for treatment of SAH and concomitant complications.

본 논문에서는 스완-간즈 카테터(Swan-Ganz catheter)를 사용하여 심장질환 중환자의 상태를 정확하게 파악하기 위해 기존의 모듈들보다 더 정밀한 데이터 측정이 가능한 모듈을 구현한다. 기존 방식은 차가운 수액을 심장에 주입하여 혈액의 온도변화와 회복시간을 측정하는 CO(Cardiac Output)를 측정하던 Bolus타입의 CO모듈이 존재하였지만, 지속적 환자 징후 관찰이 어렵다는 한계 때문에 현재는 대부분의 병원에서 사용하지 않는 상태이다. 이러한 한계를 극복하기 위해 지속적 심박출량 측정 플랫폼을 통해 효율적인 환자 징후관찰 및 상태파악이 가능 하도록 한다. 또한, 현재 기존 병원에서 심폐기능 이상 중환자의 징후관찰 및 상태파악을 위해 고가의 해외기기 도입으로 낭비되는 비용 문제를 해결하고 정밀한 데이터 수집으로 정확한 환자의 진단이 이루어 질 수 있도록 기존 모듈들의 문제점을 보완하였다.

Cardiopulmonary resuscitation(CPR) is performed by artificial ventilation and thoracic compression for the patient under emergent situation to maintain at least the minimum level of respiration and blood circulation for life survival. Quality of the pre-hospital CPR not only significantly affects the patient's survival rate but also minimizes side effects caused by CPR. Good quality CPR requires monitoring respiration, however, traditional respiratory air flow transducers cannot be used because the transducer elements are located on the flow axis. The present study developed a new technique with no physical object on the flow stream but enabling the air flow measurement and easily incorporated with the CPR devices. A turbulence chamber was formed in the middle of the respiratory tube by locally enlarging the cross-sectional area where the flow related turbulence was generated inducing energy loss which was in turn converted into pressure difference. The turbulence chamber was simply an empty enlarged air space, thus no physical object was placed on the flow stream, but still the flow rate could be evaluated. Both inspiratory and expiratory flows were obtained with symmetric measurement characteristics. Quadratic curve fitting provided excellent calibration formula with a correlation coefficient>0.999 (P<0.0001) and the mean relative error<1 %. The present results can be usefully applied to accurately monitor the air flow rate during CPR.

This study was performed to investigate the effects of Qigong training after physical training stress in untrained college students For this study, 6 voluntary subjects(male 4, female 2) were chosen in untrained students of K University. they were trained by teachers during 6 weeks and tested just before Qingong training and after 6 weeks. Each subject was performed a treadmill exercise(model Q65, Quinton Co, U.S.A.) to the all-out state. During exercise stress test, electrocardiogram, heart rate were checked by stress test monitor(model Q4500, Quinton Co, U.S.A) and also oxygen uptake, maximal oxygen uptake analyzed continuously by automatic gas analysis(model QMC, Quinton Co, U.S.A). During physical training the serum were collected 3 times, pre-experimental rest time, and serum catecholamine were measured by HPLC.T-test of statistical analysis system was used in every experiment for statistical assessment. The results of T-test on these data were summarized as follow:1.Heart rate change during exercise stress test after Qigong training was shown more decreasing tendency than before training. Especially, heart rate change after Qigong training during resting periods was decreased significantly than before training.2. Oxygen uptake change during exercise stress test after Qigong training was shown more increasing tendency than before training, And also maximal oxygen uptake after Qigong training was shown more increasing tendency than before 6 weeks.3. Epinephrine level of after Qigong training was more decreased significantly than before training in all-out state. And norepinephrine level of after Qigong training was shown more decreasing tendency than before training in all-out state and after 30 minutes rest time. Above results indicate that Qigong training for 6 weeks could be effective to elevate the cardiopulmonary functions and diminish the stress responses of the physical stress.

1994년 5월부터 1995년 12월까지 성인에서 심장수술을 시행한 122례중 18례(14.8%)에서 IABP를 순환보조장치로 사용하였다. 그중 술전에 IABP(intra-aortic balloon pump)를 시행한 경우는 9례이고, 술 중에는 7례, 그리고 술후에는 2례에서 시행하였다. 그 이유는 술전에는 저심박출, PTCA(percutaneous transluminal coronary angioplasty)의 실패였고, 술중에는 체외순환기 이탈을 위해서이며, 술후에는 술후 발생한 부정 맥 때문이었다. 환자들의 평균 나이는 61.8$\pm$6.9세(39세에서 75세)였다. 술전 및 술중에 IABP를 시행한 환자의 수술사망율은 각각 33.3, 42.9%였으며 술후 IABP를 시행한 환자는 모두 생존하였다. IABP이탈율은 술전의 경우 66.77%. 술중의 경우 85.7%였으며 술후에 시행한 IABP는 모두 이탈 가능하였다. 결론적으로 IABP는 심근 손상이 가역적인 시기에 적용할 경우, 수술전후 어느시기에나 안전하게 사용가능하며 수술전후의 혈류역학적 불안정, 체외순환기 이탈 및 저심박출증의 치료에 도움을 줄 수 있다고 판단된다.

Background: The aim of this study was to analyze the preoperative attributes and clinical impacts of complete pericardiectomy in chronic constrictive pericarditis. Methods: A total of 26 patients were treated from January 2001 to December 2013. The pericardium was resected as widely as possible. When excessive bleeding or hemodynamic instability occurred intraoperatively, a cardiopulmonary bypass (CPB; n=3, 11.5%) or an apical suction device (n=8, 30.8%) was used. Patients were divided into 2 groups: those who underwent ${\geq}80%$ resection of the pericardium (group A, n=18) and those who underwent <80% resection of the pericardium (group B, n=8). Results: The frequency of CPB use was not significantly different between groups A and B (n=2, 11.1% vs. n=1, 12.5%; p=1.000). However, the apical suction device was more frequently applied in group A than group B (n=8, 30.8% vs. n=0, 0.0%; p=0.031). The postoperative New York Heart Association functional classification improved more in group A (p=0.030). Long-term follow-up echocardiography also showed a lower frequency of unresolved constriction in group A than in group B (n=1, 5.60% vs. n=5, 62.5%; p=0.008). Conclusion: Patients with chronic constrictive pericarditis demonstrated symptomatic improvement through complete pericardiectomy. Aggressive resection of the pericardium may correct constrictive physiology and an apical suction device can facilitate the approach to the posterolateral aspect of the left ventricle and atrioventricular groove area without the aid of CPB.
