Nygaard K, Thiara A, Tronstad C, Ringdal M, Fiane A
Perfusion
. 2016 May;
31(8):648-652.
PMID: 27226328
Background:: Vacuum-assisted venous drainage (VAVD) is widely used to enhance venous blood return from patients undergoing cardiopulmonary bypass (CPB). This vacuum can accidentally reach the oxygenator of the heart-lung machine...

Ovrum E, Tangen G, Oystese R, Ringdal M, Istad R
J Thorac Cardiovasc Surg
. 2001 Feb;
121(2):324-30.
PMID: 11174738
Objectives: The use of heparin-coated circuits for cardiopulmonary bypass attenuates the postperfusion inflammatory response. Postoperative bleeding and the need for allogeneic blood transfusions are reduced, particularly in combination with lowered...

Ovrum E, Tangen G, Brosstad F, Ringdal M, Oystese R
J Thorac Cardiovasc Surg
. 1999 Oct;
118(4):610-7.
PMID: 10504624
Objective: Autotransfusion during and after cardiac surgery is widely performed, but its effects on coagulation, fibrinolysis, and inflammatory response have not been known in detail. Methods: Hemostatic and inflammatory markers...

Ovrum E, Am Holen E, Tangen G, Ringdal M
Ann Thorac Surg
. 1996 Oct;
62(4):1128-33.
PMID: 8823101
Background: The use of completely heparin coated cardiopulmonary bypass circuits in combination with a reduced systemic heparin dose has previously been shown to reduce postoperative bleeding after cardiac operations. However,...

Barstad R, Ovrum E, Ringdal M, Oystese R, Hamers M, Veiby O, et al.
Br J Haematol
. 1996 Sep;
94(3):517-25.
PMID: 8790153
The possible activation of monocytes to express tissue factor procoagulant activity (TF-PCA) during CPB (cardiopulmonary bypass) was investigated. 22 patients undergoing myocardial revascularization were randomly assigned to two groups. In...

Ovrum E, Fosse E, Mollnes T, Am Holen E, Tangen G, Abdelnoor M, et al.
Eur J Cardiothorac Surg
. 1996 Jan;
10(1):54-60.
PMID: 8776186
Complete heparin-coated extracorporeal circuits, including cardiotomy reservoir, have recently become available for routine cardiac surgery. The effects on complement and granulocyte activation using a heparin-coated circuit in combination with reduced...

Ovrum E, Mollnes T, Fosse E, Holen E, Tangen G, Ringdal M, et al.
Ann Thorac Surg
. 1995 Dec;
60(6):1755-61.
PMID: 8787476
Background: Cardiopulmonary bypass with heparin-coated circuits allows reduced amounts of systemic heparin. Heparin inhibits activation of the complement cascade experimentally, but the effects of different levels of systemic heparin on...

Ovrum E, Mollnes T, Fosse E, Holen E, Tangen G, Abdelnoor M, et al.
J Thorac Cardiovasc Surg
. 1995 Dec;
110(6):1623-32.
PMID: 8523872
Complement and granulocyte activation were studied in cardiopulmonary bypass circuits completely coated with either end-attached covalent-bonded heparin, the Carmeda BioActive Surface, or with the Duraflo II bonded heparin, in combination...

Ovrum E, Holen E, Tangen G, Brosstad F, Abdelnoor M, Ringdal M, et al.
Ann Thorac Surg
. 1995 Aug;
60(2):365-71.
PMID: 7646097
Background: When heparinized circuits are used for cardiopulmonary bypass, the amounts of heparin and protamine administered systemically can be reduced. However, it is not entirely known what effects this reduction...

Ann Thorac Surg
. 1995 Jul;
60(1):156-9.
PMID: 7598579
Background: Ventricular fibrillation after declamping of the aorta after cardioplegic arrest is commonly managed by direct-current countershock. However, in coronary artery bypass grafting, placement of the electrodes can cause mechanical...
