Quantification of extracorporeal white cell and platelet deposition in cardiopulmonary bypass: comparison of membrane and bubble oxygenators

Autor: David J. Wheatley, Will Martin, McQuiston Am, A.C. Tweddel

Publikováno v: Nuclear medicine communications. 17(5)

Cardiopulmonary bypass is known to activate both white cells and platelets. The aim of this study was to investigate whether the use of bubble and membrane oxygenators results in different degrees of deposition in the filter and oxygenator of the byp

Respiratory dysfunction and white cell activation following cardiopulmonary bypass: comparison of membrane and bubble oxygenators

Autor: A.C. Tweddel, McQuiston Am, Martin W, Belch J, McLaren M, M.M. El-Fiky, Roger Carter, David J. Wheatley

Publikováno v: European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery. 10(9)

Cardiopulmonary bypass induces respiratory dysfunction postoperatively, with activation of both the complement system and white cells implicated. This study compared the effects of bubble and membrane oxygenators for cardiopulmonary bypass in terms o

A comparison of dobutamine and maximal exercise as stress for thallium scintigraphy

Autor: I. Hutton, Will Martin, A.C. Tweddel, Wallbridge Dr

Publikováno v: European Journal of Nuclear Medicine. 20

In the assessment and evaluation of patients with suspected coronary artery disease there is a need for pharmacological stress combined with thallium scintigraphy. Thallium images were obtained following stress both with dobutamine infusion (5-20 mic

A comparison of maximal exercise and dipyridamole thallium-201 planar gated scintigraphy

Autor: I. Hutton, A.C. Tweddel, Gavin Main, Will Martin

Publikováno v: European Journal of Nuclear Medicine. 19

Both symptom-limited maximal exercise and intravenously given dipyridamole stress (0.56 mg/kg over 4 min with a 2 min walk) gated thallium scans were performed in 22 patients undergoing coronary arteriography for the assessment of chest pain. All sca

Myocardial perfusion imaging with xenon-133

Autor: A.C. Tweddel, Will Martin

Publikováno v: Developments in Cardiovascular Medicine ISBN: 9789401050838

In 1948, Eckenhoff et al. [1] described a method of measuring coronary flow based on the principle that an inert gas (nitrous oxide) diffuses across the capillary membrane in proportion to the rate of coronary flow. A concentration curve was obtained
