Cardiac arrest is a series of conditions that occur when the heart is stopped, regardless of the cause. Cardiac arrest due to heart disease is included in the cause of death in korea every year and is unpredictable. One of the only ways to save a patient's life when a cardiac arrest is cardiopulmonary resuscitation is to maintain circulation through this procedure. Therefore compared the quality of chest compressions with visual information using mirrors. There was a significant difference in the mean depth of chest compressions(48.93±6.76, 53.86±4.56, <0.001), and there was also a difference in compression to relaxation ratio(0.87±0.13, 0.96±0.10, <0.002). There was also a significant difference in attitude awareness(4.93±0.85, 8.14±1.38, <0.001).

The purpose of this study was to ascertain whether or not to recover the spontaneous circulation of patients with cardiac arrest before arrival in the emergency room for 5 years (2012 to 2016), and try to investigate the factors affecting this. In this research, we used the "raw material for acute cardiac arrest survey" conducted in "Disease management headquarters" from 2012 to 2016 for the whole country of our country as the main material. In this study, 136,212 cardiac arrest patients were analyzed in the study data of the cardiac arrest in the country during the 5 years from 2012 to 2016. We performed a Chi-square analysis to analyze the recovery of spontaneous circulation before arrival in the emergency room according to general characteristics, social·demographic characteristics, and developmental characteristics. and We performed a Binary logistic regression analysis to determine the factors affecting the recovery of spontaneous circulation. The analysis results of this study show that whether CPR sustained transport before endoplasmic reticulum arrival, whether to witness an acute cardiac arrest before arrival in the emergency room, the type of general cardiopulmonary resuscitation, the location of acute cardiac arrest, the acute heart Causes of stoppage cause factor of whether spontaneous circulation recovery recovers before arrival of the endoplasmic reticulum(P<0.001, P<0.01). Therefore, it is necessary to strengthen systematic government health policy implementation and dissemination and health education focusing on factors that affect recovery of spontaneous circulation of cardiac arrest patients.

Retrograde myocardial protection is widely accepted in CABG operation because of the limitations of the antegrade method in the coronary arterial stenosis lesions. We analyzed 76 c ses of retrograde myocardial protection among 96 cases of CABG operation performed between April 1994 and August 1995, There were 48 males and 25 females, and the mean age was 58.2 $\pm$ 8.3 years. 53 patients (70%) were operated for unstable angina, 14 (18%) for stable angina, 6 (8%) for post-infarct angina, 1 (1%) for acute myocardial infarction, and 2()%) for failed PTCA. Preoperative coronary angiography revealed 3-vessel disease in 42 cases, 2-vessel disease in 11, 1-vessel disease in 10, and left main disease in 13 cases. We used SVG(63 cases), LIMA(69 cases), RIMA(11 cases), radial artery(6 cases), and gastroepiploic artery(1 case) for the grafts. Mean anastomosis was 3.2 $\pm$ 1.1. We protected the myocardium with antegrade induction and retrograde maintenance in all the cases except a case of retrograde induction and maintenance. During the aortic cross-clamping, blood cardioplegia was administered intermittently in 19 cases, and continuously in 57 In 39 cases, we used retrograde ardioplegia and antegrade perfusion of RCA graft simultaneously. We had no operative motality. Perioperative complications were arrhythmia in 15 cases, perioperatve myocardial infarction in 10, low cardiac output syndrome In 8, transient neurologic problem in 7, transient psychiatric problem in 6, ARF in 3, bleeding in 2, pneumonia in 2, wound infection in 1, and duodenal ulcer perforation in 1 . In this report, we experienced 76 cases of CABG operation with retrograde myocardial protection under the acceptable operative risk without operative mortality.

Background: In cardiac surgery, hypothermia is associated with a number of major disadvantage, including its detrimental effects on enzymatic function, energy generation and cellular integrity. Warm cardioplegia with normothermic cardiopulmonary bypass cause three times more incidence of permanent neurologic deficits than the cold crystalloid cardioplegia with hypothermic cardiopulmonary bypass. Interruptions or inadequate distribution of warm cardioplegia may induce anaerobic metabolism and warm ischemic injury. To avoid these problems, tepid blood cardioplegia was recently introduced. Material and Method: To evaluate whether continuous tepid blood cardioplegia is beneficial in clinical practice during valvular surgery, we studied two groups of patients matched by numbers and clinical characteristics. Warm group(37$^{\circ}C$) consisted of 18 patients who underwent valvular surgery with continuous warm blood cardioplegia. Tepid group(32$^{\circ}C$) consisted of 17 patients who underwent valvular surgery with continuous tepid blood cardioplegia. Result: Heartbeat in 100% of the patients receiving continuous warm blood cardioplegia and 88.2% of the patients receiving continuous tepid blood cardioplegia converted to normal sinus rhythm spontaneously after removal of the aortic cross clamp. There were no differences between these two groups in CPB time, ACC time, the amount of crystalloid cardioplegia used and peak level of potassium. During the operation, the total amount of urine output was more in the warm group than the tepid group(2372${\pm}$243 ml versus 1535${\pm}$130 ml, p<0.01). There were no differences between the two groups in troponin T level measured 1hr and 12hrs after the operation. Conclusion: Continuous tepid blood cardioplegia is as safe and effective as continuous warm blood cardioplegia undergoing cardiac valve surgery in myocardial protection.

Purpose: Cardiac arrest has multiple characteristics that need to be approached as an integrated method according to the various changes in the body system. This study was performed to develop a useful guideline for early detection of cardiac arrest by revealing the attributes of cardiac arrest through a concept analysis. Methods: This study was conducted according to the Walker and Avant's concept analysis method. Systematic literature review and in-depth interview with nurses who experienced cardiac arrest situation were conducted. Based on the literature reviews and in-depth interviews with nurses, the attributes and the empirical referents of the concept of cardiac arrest were elicited. Results: The definable attributes of cardiac arrest were 1) loss of consciousness, 2) abnormal respiratory condition, 3) abnormal cardiovascular signs. Cardiac arrest was found to occur by several antecedents such as cardiac problem, non-cardiac problem, or general problem, whereas ischemia and re-perfusion injury, which can lead to multiple organ failure and death, were derived as consequences. Conclusion: In this study, the concept analysis eliciting attributes and empirical referents is found to be useful as a guideline for understanding and managing cardiac arrest. Based on these findings, clinical providers are expected to make a precise and rapid decision on cardiac arrest and respond quickly, which may increase survival rate of the patients underwent the arrest event.

Purpose : This study aimed to identify the incidence of peripheral cyanosis and the characteristics and clinical results of patients with therapeutic hypothermia after a cardiac arrest. Methods : Data were collected from April to June 2021 via the electrical medical records of 95 patients with therapeutic hypothermia for 72 hours after a cardiac arrest admitted to an acute care unit at a tertiary hospital between January 1, 2016, and December 31, 2019. The data were analyzed using descriptive statistics and a t-test, Mann-Whitney U test, Chi-squared test, Fisher's exact test, and logistic regression using SPSS/WIN. Results : The incidence of peripheral cyanosis was 20%. In the peripheral cyanosis group, peripheral vascular disease, fibrinogen, vasopressor, infection, disseminated intravascular coagulation, acute physiology, chronic health evaluation II score on the second hospital day, nursing intervention, and mortality on the seventh hospital day were higher. The level of fibrinogen and use of vasopressors affected the occurrence of peripheral cyanosis. Conclusion : Considering the influencing variables, careful observation is necessary for patients with high fibrinogen levels and vasopressor use. These results provide basic data to recognize the need for nursing intervention for peripheral cyanosis and encourage nurses to deliver them during therapeutic hypothermia.

This study is to collect a basic data of how Cardiopulmonary Resuscitation (CPR) procedure can influence to cardiac arrest patient with and without the Depth Device during the average transport time period. The data has achieved by comparing result sheet of CPR procedure by hands only versus with Depth Device by twenty 1st and 2nd class Emergency Medical Technician (EMT) from five different fire stations in city of Chong-Ju, and twenty Emergency Rescue major students who completed the BLS provide course. The experiment participators experienced loss of compression depth and rate increase over time. However, the CPR procedure with Depth Device shows that both EMT and students to allow maintaining both the compression depth and rate. The experiment leaves a positive result for CPR operators and considers being valuable domain for cardiac arrest patient.
