Hypoxaemia 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 کاملCONTINUING EDUCATION Coagulation and Platelet Function During Cardiopulmonary Bypass Surgery
Bachmann and coworkers in Chicago have performed a careful study of coagulation parameters after cardiopulmonary bypass surgery .1 In 512 patients, they found a 4% incidence of postoperative bleeding. More than half of these cases were due to surgically correctable causes. About 2% of the population were considered to be bleeding because of an acquired coagulation disorder. One half of these ca...
متن کاملThyroid function during coronary surgery with and without cardiopulmonary bypass.
OBJECTIVE Cardiopulmonary bypass (CPB) is associated with thyroid hormone changes consistent with euthyroid sick syndrome. Similar changes have been observed after general surgical operations. Thyroid hormone changes and their association with global oxygen consumption were studied in low-risk patients undergoing coronary artery bypass grafting (CABG) with and without CPB. METHODS Fifty-two p...
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...
