    Introduction: Lactate dehydrogenase (LDH) is widely used as an indicator of pump thrombosis in a centrifugal pump. However, due to the low specificity of LDH, pump thrombosis is difficult to detect in the clinical environment. We measured plasma free hemoglobin (pfHb) with the portable device in ICU. The goal of this investigation is to evaluate its diagnostic ability for pump thrombosis. Methods: We enrolled 31 consecutive patients who needed Extracorporeal Membrane Oxygenation (ECMO) therapy and pfHb was determined with HemoCue® plasma/Low Hb photometer. Pump thrombosis was analyzed macroscopically at the timing of pump explantation or exchange. Also, we divided the pump thrombosis into a grading scale by the place of thrombosis. Results: The median of peak pfHb was significantly lower in the none thrombus group (0.03 g/dL) than that of in the thrombus group (0.05g/dL) (p = 0.01). In our grading criteria, pfHb was significantly higher when the thrombus is existing near the shaft (p = 0.015). Contrary, no significant difference was found for LDH. The ROC analysis of pfHb revealed an AUC of 0.77 for detecting pump thrombosis with the best statistical cutoff value at 0.05 g/dL (specificity, 78%; sensitivity, 77%). Also, ROC analysis of LDH was performed (AUC, 0.44; cutoff value, 1200 IU/L; specificity, 59%; sensitivity, 54%) and compared with pfHb. AUC was significantly higher in pfHb (p = 0.04). Conclusion: Our results showed the efficacy of pfHb for detecting centrifugal pump thrombosis.

    A 63-year-old man visited a local clinic because of fever. He tested positive for influenza virus A H1N1 antigen, and was administered oseltamivir. On the fifth day of illness, he showed severe respiratory failure. Therefore, he was transported to our hospital, placed on noninvasive positive airway pressure ventilation, and started on peramivir, short-term high-dose steroid therapy. On the sixth day of illness, he developed disseminated intravascular coagulation (DIC), which was treated with anticoagulation therapy. Because the dyspnea worsened, he was intubated on the 13th day of illness, and placed on extracorporeal membrane oxygenation (ECMO) on the next day. However, because his condition did not improve, he had to be placed on ECMO for a long period of time. The patient's condition was complicated by upper gastrointestinal bleeding on the 34th day, and he died of multiple organ dysfunction on the 52nd day. This case suggests that such patients should be carefully managed with bleeding complications in mind, because treatment with ECMO is associated with the development of DIC-like conditions.

    Nearinfrared spectroscopy (NIR) is a procedure which permits noninvasive measurement of cerebral oxygenated and deoxygenated hemoglobin. The purpose of this study is to examine how accurately NIR represents separate and nonoverlapping dimensions among monitoring modalities during cardiopulmonary bypass (CPB). In 66 patients (50 male, 16 female, age 30-74 (mean 63.8 ±9.9) yrs) who underwent coronary artery bypass grafting during CPB, 321 sampling points were defined. Arterial blood pressure, central venous pressure, pulmonary arterial pressure, perfusion index, arterial hemoglobin concentration, and esophageal temperature were recorded at every sampling point. Oxygen and carbondioxide partial pressure and oxygen saturation were measured in arterial and venous blood. Cerebral oxygenated, deoxygenated, and total hemoglobin were measured by NIR spectroscopy. We used the multivariate statistical technique of factor analysis. Seven factors are extracted and rotated orthogonally through the Varimax procedure. Bartlett's chi-square test of the correlation matrix is significant at the 0.0001 level. We have named the factors Oxygen, Cerebral Oxygen, Carbondioxide, Left-Heart, Right-Heart, Perfusion Index, and Hemoglobin. Cerebral Oxygen factor contains NIR-measured cerebral oxygenated and deoxygenated hemoglobin. We conclude that NIR spectroscopy monitored separate and distinct clinical dimensions during CPB. NIR may be a useful new monitoring tool for assessing cerebral oxygenation in open-heart surgery.

    We have developed a new vacuum control system that can keep a hard-shell venous reservoir at a certain target low negative pressure. This device offers assistance with venous drainage and cardiotomy suction during cardiopulmonary bypass (CPB). It consists of an aspiration valve that controls the internal pressure of the hard-shell venous reservoir by releasing the source flow of the vacuum pump to atmospheric pressure. In this study, we used this device in clinical mock-up circuits to evaluate the changes in internal pressure of the hard-shell reservoir. The target pressure of the reservoir varied from-10 mmHg to-70 mmHg. This device could control changes in the internal pressure within a range of 4 mmHg when all cardiotomy suction tubes were switched on and off. This study showed that this device can stabilize the internal pressure of the hard-shell venous reservoir and offers improved handling of venous drainage during CPB. The device would be available not only for venous drainage but for cardiotomy sucking, and would be an applicable system for Minimally Invasive Cardiac Surgery and numerous other clinical uses.

    In the present study we investigated the changes in contact factors in cardiopulmonary bypass (CPB) using hemofiltration (HF) for priming blood. Red cell concentrates containing MAP (RC-MAP) and albumin solution were used for the pnming. Blood samples were collected from RC-MAP, priming solution before and after HF, hemofiltrate and patient before CPB, and 60 minutes after CPB and at the end of CPB. In 10 cases, high molecular weight kininogen (HMWK), prekallikrein (PK), factor XII (F XII) and bradykinin (BK) levels were examined in each sample. Through hemodilution and contact with the CPB circuit, HMWK, PK and F XII were consumed and a large quantity of BK was generated, but BK was hemofiltrated well. At the beginning of CPB, HMWK, PK and F XII were significantly decreased, since then they were not significantly changed. BK was not significantly changed during CPB. Because BK increases vasodilatation and capillary permeability, HF is useful to prevent a drop in blood pressure at the beginning of CPB and for the reduction of postoperative edema, especially in neonates and infants.

    In order to compare the effect of acid base management on cerebral bleed flow and metabolism during retrograde cerebral perfusion (RCP), we have studied 79 blood gas samples in the α-stat and 16 ones in the pH-stat management from the patients undergoing aortic arch surgery. During retrograde cerebral perfusion at a nasopharyngeal temperature of 20°C, the pump flow was adjusted so that the pressure of the SVC would be maintained around 25 mmHg. In the pH-stat management, RCP flow rate was significantly greater and vascular resistance was significantly lower than those in the α- stat management. Lactic acid consumption, lactic and pyruvic acid rate and the glucose consumption showed no significant difference between groups. The pH-stat management revealed lower vascular resistance and greater RCP flow rate than did the α-stat management due to higher PaCO2 levels. The pH-stat management may have some efficacy for the brain circulation and the brain protection. However, the disadvantage of high PaCO2 levels has not been clarified. Further studies will be necessary to refine the standard for RCP management.

    We have developed a low negative pressure vacuum suction system in which cardiotomy suction is performed by the negative pressure of the venous reservoir controlled by a vacuum controller. We have employed this vacuum suction system with a centrifugal pump as a totally roller pumpless cardiopulmonary bypass (CPB) system. In this study, the clinical availability and hemocompatibility of our totally roller pumpless CPB system were evaluated by a randomized prospective study. Thirty patients undergoing aortocoronary bypass grafting were assigned to the study. Data from seventeen patients treated with a totally roller pumpless CPB system were compared with data from 13 treated with a conventional roller pump CPB system. Totally roller pumpless CPB reduces hemolysis, showing lower plasma free hemoglobin levels (81.8 ± 25.0 versus 42.0 ± 16.3 at 30 min after CPB initiation, p < 0.05), higher plasma haptoglobin levels (37.8 ± 36.6 versus 77.2 ± 31.3 at 120 rain after CPB, p < 0.05), and lower blood lactate dehydrogenase (LDH) levels (1391 ± 497 versus 972 ± 187, p < 0.01) than those of CPB with a roller pump suction with no significant difference between platelet counts. Arterial blood oxygen tension after using a totally roller pumpless CPB system was slightly better than that with a roller pump (396 ± 48 versus 437 ± 43, p = 0.069); however, there was no significant difference in intubation times between groups. A totally roller pumpless CPB system provides sufficient biocompatibility for the blood to reduce hemolysis significantly and simplifies and miniaturizes the entire CPB system to achieve good visuality and handling for control as well.

In this study, a clinical availability and hemocompatibility of a negative pressure suction in CPB system are evaluated on a randomized prospective study. Eighty, patients underwent aortocoronary bypass grafting were assigned. Forty patients with a negative pressure suction system (Group B) were compared with forty with a conventional roller pump suction system (Group A). A group B reduces hemolysis showing lower plasma free hemoglobin levels (56.6±28.1 vs 84.6±33.9 at 60min after CPB, p<0.05), higher plasma haptoglobin levels (37.8±36.6 vs 77.2±31.3 at 120rnin after CPB, p<0.05) and lower blood LDH levels (1390.6±496.5 VS 972.3±186.5, p<0.01) compared with a group A, while there were no significant difference of platelet counts. Arterial blood oxygen tension after using a negative pressure suction was slightly better than other (395.9±48.3 vs 436.7±42.7, p=0.069), however, there were no significant differences of intubation time between groups. A negative pressure suction system provides sufficient hemocompatibility for the blood to reduce hemolysis significantly and simplifies and miniaturizes the whole CPB system.

    Blood trauma was estimated in 68 consecutive adult patients who underwent open heart surgery without blood transfusion during CPB so as to clarify possible differences among three centrifugal pumps (BP-80:20 patients; HPM-15:18 patients; SP45:24 patients) and roller pump (R, 6 patients). Serum hemoglobin (S-Hb) and ptatelet counts (PLT) were measured before (just after induction of anesthesia) and during CPB. Each value was corrected by hemodilution, and the amount of increase of S-Hb (ΔS Hb) and the degree of PLT change from the value before CPB (%PLT) were calculated and compared. Although AS Hb gradually increased during CPB, the values of the four groups did not show any significant deference. The %PLT, on the other hand, decreased during CPB, but we could not find any significant difference among the four groups. We conclude from these findings that the centrifugal pump and the roller pump may cause blood trauma in the same degree during short term CPB in adult patients.

The %PLT, on the other hand, decreased during CPB, but we could not find any significant difference among the four groups. We conclude from these findings that the centrifugal pump and the roller pump may cause blood trauma in the same degree during short-term CPB in adult patients.

    MENOX AL 6000®, which was newly developed for solving serum leakage problems in long term use and activation of platelets, was clinically evaluated in 20 cases, in comparison with other membrane oxygenators, CAPIOX SX® (10 cases) and UNIVOX® (12 cases). MENOX AL-6000®, made of two-layer hollow fiber, showed slightly low oxygen transfer and required significantly more V̇/Q̇ for CO2 removal than CAPIOX SX®, but there were no problems in clinical use. The decreases of platelet counts and plasma free Hb during extracorporeal circulation were very slow, and no significant differences were recognised among the three oxygenators. The function of gas exchange in MENOX AL-6000® was not disturbed as time went on. From its structural characteristics. MENOX AL-6000® appears useful for open heart surgery and promises to be effective for longer assist bypass with good result.

    In consecutive 207 patients, we applied “Low-vacuum suction method”, in which sucking and venting the blood during cardiopulmonary bypass are performed using the hard shell venous reservoir with a low negative pressure. A little unstability of negative pressure in the reservoir, which was sometimes found during running of cardiopulmonary bypass, scarcely affects holding blood level in it. The blood level in the reservoir immediately responded to the blood volume with the short suction circuit, which makes it easy to handle cardiopulmonary bypass. In the case of using several suction circuits concurrently, suction tubes should be turned on and off in the operating field. A roller pump suction method was employed in the control group. Serum hemoglobin, haptoglobin, platelet count, platelet aggregation were measured in each group. Increase of serum hemoglobin and haptoglobin in the group with “Low-vacuum suction method” were significantly smaller than those in the control group. Platelet count and platelet aggregation did not show significant difference. It was concluded that “Lowvacuum suction method” can reduce hemolysis during CPB.

    We studied clinical availability ofCAPIOX SX in comparison with UNIVOX and MENOX AL6000 in relation to gas exchange performance. One hundred and nine patients who underwent various cardiac operations with CPB were derived into 3 groups, CAPIOX SX group (group C; 58 patients), UNIVOX group (group U; 29 patients) and MENOX group (group M; 22 patients). There were no significant diffemces among the 3 groups in regard to age, sex, weight, BSA, CPB time, aortic clamping time and minimum rectal temperature. Carbon dioxide elimination capacity of group C was almost equal to that of group U and better than that of group M. Effective lung blood flow ratio (QP/QT) showed an enough oxygene uptake capacity in all groups. An initial priming volume was significatly lower in group C than that of the other two groups. We concluded that CAPIOX SX is one of the usefull oxygenator for clinical application from the standpoint of the gas exchange performance.

    Nafamostat Mesilate (FUT) is a protease inhibitor of coagulation, fibrinolysis and platelet aggregation. Thirty-four cases of heart surgery undergone using FUT 40mg/hour were evaluated. The activated coagulation time was significantly prolonged in the FUT group compared to the heparin used group. Total heparin and protamine dosage required were significantly reduced in the FUT group. There were no significant differences in the platelet count between the 2 groups under study.However, the amount of postoperative bleeding was reduced in the FUT group. FUT is therefore considered useful to preserve the blood during cardiopulmonary bypass and to prevent blood loss in open heart surgery.

    Concentrations of Manganese-containing superoxide dismutase (Mn-SOD) were measured perioperatively by enzyme immunoassay in serial samples of arterial and coronary sinus blood and urine taken from 18 patients undergoing mitral valve surgery. The mean Mn-SOD concentration in the arterial blood samples was 66.2 (SD 16.1 ng/ml) at induction of anesthesia, increased gradually after reperfusion and peaked on the 2nd post-operative day [150 (SD 58.3) ng/ml]. The mean concentration of Mn-SOD in the coronary sinus blood samples was significantly higher than in the arterial samples only at the 6th hour after reperfusion [97 (SD 21.8) ng/ml vs 90.3 (SD 20.9) ng/ml, p<0.05]. Although concentrations of Mn-SOD in blood did not increase in 8 patients who underwent midline sternotomy for a mediastinal tumor, they increased dramatically in 3 patients who sustained a perioperative myocardial infarction. During open heart surgery the peak values of plasma Mn-SOD concentrations were correlated to that of plasma creatine kinase-MB concentrations (r=0.5532, n=18, p<05) and cardiac ischemic period (r=0.5186, n=18, p<05). Although the meaning of an increase in plasma Mn-SOD concentrations during open heart surgery is not clarified, it may be released from the heart and anywhere also in the body damaged during cardiopulmonary bypass.

    Emergency coronary angiography, emergency reperfusion therapy and intra-aortic balloon pumping improved clinical results of acute myocardial infarction. But patients with sever pump failure need more effective mechanical assist. Percutaneous cardiopulmonary support (PCPS) is an useful alternative procedure in such situation. Two of 5 patients who were resuscitated by PCPS survived after coronary angioplasty. Twenty-five cases of 31 emergency or urgent surgical cases were salvaged but left heart bypass by assist device was necessary in 2 cases. Thirty-seven old man who was suffering from acute occlusion of left main trunk underwent emergency bypass surgery, but he died after 3 months from heart failure and infection in spite of being weaned from left heart assist after 10 days from its application. This patient was considered to be a candidate for heart transplantation.

    Problems of centrifugal pump were studied in 28 cases in which centrifugal pump were used as a postoperative left heart assist or percutaneous cardiopulmonary support (PCPS). One of 3 cases which required left heart assist postoperatively was weaned but could not be salvaged. Eight of 17 cases (47%) which underwent emergency PCPS were weaned and 7 of them (41%) survived. Emergency PCPS was used in 10 cases as a cardiopulmonary resuscitation. Four of them showed complete recovery of consciousness 10 minutes to 17 hours later. Duration of cardiopulmonary resuscitation was 15 to 43 minutes (mean 30 minutes) in cases with complete recovery of consciousness. Elective PCPS was adopted in 8 cases during supported percutaneous transluminal angioplasty. In 6 of them, good results and symptomatic improvement were obtained. Centrifugal pump is easy for setting of the cardiopulmonary bypass circuit and can make it small-sized. Such a pressure control as a roller pump is not necessary. Centrifugal pump is very useful and safe in clinical use.

    A 53-yr-old male and a 12-yr-old female were suffered from fulminant myocarditis. Because conventional therapy such as volume replacement, inotropic support, cardiac pacing and intraaortic balloon pumping (IABP) failed to improve their circulatory state, they received percutaneous cardiopulmonary support (POPS) for 107 hours and 227 hours, respectively. The both cases showed tremendous circulatory improvement as soon as PCPS started and successfully weaned. A 37-yr-old female was transferred to our hospital. Although ECG revealed multifocal VPC and short run, drug therapy failed to control them. Then she developed sudden ventricular fibrillation. Endotracheal intubation was performed and cardiac massage was started immediately. As drug therapy and cardioversions were ineffective, PCPS was started with a flow rate of 4L/min. The arrhythmias disappeared 15 hours later and PCPS could be discontinued after 39 hours. Traditional methods of cardiac bypass usually require surgical exposure of the great vessels, which can be time-consuming and moreover may lead to a serious loss of blood. We have developed a simple PCPS system using percutaneous cannula, a centrifugal pump and an artificial lung. The circuit of the system is set up beforehand and sterilized for emergency situation. PCPS appears to be beneficial in the treatment of circulatory collapse and resuscitation which are refractory to conventional therapy.

    To protect the cerebral function during hypothermic circulatory arrest, continuous retrograde cerebral perfusion (CRCP) of oxygenated blood from the superior vena cava was performed in 5 cases with dissecting aneurysm. After the body temperature reached 20°C, CRCP was strated by the flow rate of 150-620 mL/min. The central venous pressure was maintained between 20 to 40 mmHg. The duration of circulatory arrest and retrograde cerebral perfusion was 50 to 73 mins. In 4 cases, the postoperative recovery was excellent without neurologic deficit. However, in the other case in which resuscitation was attempted in the emergency room, severe brain edema was the cause of death. CRCP by oxygenated blood during hypothermic circulatory arrest is a useful and effective means during the operation of the aortic arch.

    A previously well 53-year-old man with fulminant myocarditis is presented. Cardiogenic shock and medically refractory low cardiac output syndrome were unsuccessfully treated using an intraaortic balloon pump. A percutaneous extracorporeal bypass system improved hemodynamics, DIC and other multiorgan injuries following acute myocarditis.

    In 62 cases of open heart surgery, autotransfusion of concentrated selected washed red cells from surgical field was carried out. The use of automated Cell Saver made it possible to save 621ml of homologous blood. In 54% of these cases, the open heart surgery was performed without any homologous blood transfusion.<br>There was no difference in intraoperative and post operative laboratory examinations between cases with no blood transfusion and with homologous blood transfusion.<br>Plasma free hemoglobin level was high in the Cell Saver processed blood. Bacterial culture was possitive in 51.7% of processed blood. It was concluded that these findings should be in mind when Cell Saver processed blood is used.
