Complement and neutrophil activation during cardiopulmonary bypass: a randomized comparison of hypothermic and normothermic circulation.
OBJECTIVE Activation of both complement and neutrophils has been demonstrated to be involved in many pathological reactions following cardiopulmonary bypass (CPB). The aim of the present study is to evaluate the effect of normothermic and hypothermic CPB on both complement and neutrophil activation. METHODS Two groups of patients (n = 20 each) scheduled for elective coronary artery bypass gra...
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 کاملThe Effect of Methylprednisolone on Complement Activation during Cardiopulmonary Bypass
____________ _ A prospective randomized trial in 80 patients having heart surgery was undertaken to test the hypothesis that steroids (ST) (methylprednisolone, 30 mg/kg) would prevent or reduce complement activation during cardiopulmonary bypass (CPB) with membrane (MEM) or bubble (BUB) oxygenators. Group I patients had MEM and ST; Group II, MEM without ST; Group III, BUB and ST; Group IV, BUB ...
متن کاملAPT070 inhibits complement activation during in vitro cardiopulmonary bypass.
BACKGROUND The proteins of the complement cascade play an important role in inflammation and the immune response. They have been shown to be activated during cardiopulmonary bypass (CPB), and may be responsible for the inflammatory response to CPB. We looked at the effect of APT070, an anti-complement agent, on human blood during in vitro CPB. MATERIALS AND METHODS Four hundred millilitres of...
متن کاملActivation of the hemostatic system during cardiopulmonary bypass.
Cardiopulmonary bypass (CPB) is a unique clinical scenario that results in widespread activation of the hemostatic system. However, surgery also results in normal increases in coagulation activation, platelet activation, and fibrinolysis that are associated with normal wound hemostasis. Conventional CPB interferes with normal hemostasis by diluting hemostatic cells and proteins, through reinfus...
