Myocardial Preservation during Hypothermic Cardiopulmonary Bypass: A Team Endeavor
____________ _ Myocardial failure is the primary cause of death following operation using hypothermic cardiopulmonary bypass. The mean mortality rate for coronary bypass in Medicare patients in the United States for 1984 was 5.5%.1njury to the heart is caused by aortic cross-clamping or total circulatory arrest. The lesion of hypoxia is characterized by progressive acidosis. The severity of aci...
متن کاملMyocardial protection of warm blood cardioplegic induction during cardiopulmonary bypass.
In his prospective randomized clinical study, we evaluated the myocardial protection of warm blood cardioplegic induction and cold blood cardioplegic induction, respectively, during cardiopulmonary bypass. Twenty-eight adult patients who underwent valve replacement were randomly divided into two groups: group T (14 cases) received cold (6-8 degrees C) blood cardioplegic induction after ECG show...
متن کاملHypoxaemia during cardiopulmonary bypass.
For cardiopulmonary bypass during open-heart surgery we use a bubble oxygenator and a technique of haemodilution and moderate hypothermia. During the course of routine perfusion we have observed arterial desaturation in a number of patients and in five patients the desaturation was marked (SaO2<85%)'. The low arterial oxygen saturations occurred mainly in the rewarming period. This report is of...
متن کاملBlood Filtration During Cardiopulmonary Bypass
Particulate microembolization during extracorporeal circulation is thought to contribute to cerebral, pulmonary and other post-operative complications following cardiac surgical procedures. 11° Factors which have been implicated in microembolic phenomena during cardiopulmonary bypass include: 1 ) transfusion of stored blood ,I· 2 ' '· 11 ' ' 3 22 2) formation of platelet aggregates in the patie...
متن کاملProcoagulant triggers during cardiopulmonary bypass.
Recently, Boisclair et all has given us an important clue to show the main trigger to coagulation activity during cardiopulmonary bypass (CPB). They observed the increase of factor IX activation peptide during CPB, which shows a strong correlation with the increase of prothrombin fragment F1 + 2. In contrast, they found no significant increase in factor XIIa levels during CPB. This activation p...
