Oxygenator exhaust capnography for prediction of arterial carbon dioxide tension during hypothermic cardiopulmonary bypass.
Continuous monitoring and control of arterial carbon dioxide tension (P(a)CO2) during cardiopulmonary bypass (CPB) is essential. A reliable, accurate, and inexpensive system is not currently available. This study was undertaken to assess whether the continuous monitoring of oxygenator exhaust carbon dioxide tension (PexCO2) can be used to reflect P(a)CO2 during CPB. A total of 33 patients under...
متن کاملIn vitro validation of the Affinity NT oxygenator arterial outlet temperatures.
During cardiopulmonary bypass, the rates of cooling and rewarming and the maximum temperatures attained are implicated in patient morbidity. Thus, accurate oxygenator arterial outlet temperature measurements are needed. The purpose of this study was to determine the accuracy of the arterial outlet temperature probe on the "Affinity NT" membrane oxygenator in measuring perfusate temperatures. An...
متن کاملProblems of Cold Agglutinins in Cardiac Surgery: How to Manage Cardiopulmonary Bypass and Myocardial Protection
Cold agglutinins are of unique relevance in cardiac surgerybecause of the use of hypothermic cardiopulmonary bypass (CPB). Cold autoimmune diseases are defined by the presence of abnormal circulating proteins (usually IgM or IgA antibodies) that agglutinate in response to a decrease in body temperature. These disorders include cryoglobulinemia and cold hemagglutinin disease.Immunoglobulin M aut...
متن کاملExtraction of Nitroglycerin by a Membrane Oxygenator
This study examined the extraction efficiency of a membrane oxygenator for nitroglycerin (NTG). An In-Vitro cardiopulmonary bypass circuit was constructed to mimic clinical conditions. A NTG solution (150 ng/ml) was placed into the circuit via a glass cardiotomy reservoir and circulated at 5 Ll min for 60 min. Analysis of NTG samples obtained during the study showed that the oxygenator initiall...
متن کاملThe effects of cardiopulmonary bypass with hollow fiber membrane oxygenator on blood clotting measured by thromboelastography.
In cardiac surgical patients we investigated the effects of cardiopulmonary bypass (CPB) with a hollow fiber membrane oxygenator on blood clotting measured by thromboelastography (TEG). We found only a minimal change in the strength of blood clot described either by the TEG parameter MA (maximum amplitude) or by the shear modulus G calculated from MA. After CPB there was also a significant tend...
