Why the study?
Does the type of oxygenator (membrane vs. bubble) affect gas transfer and gaseous microemboli production during open-heart surgery?
Population
60 adult patients undergoing open-heart surgery requiring clinical perfusion
Comparison
Membrane oxygenator or one of five bubble… vs Comparison among the different oxygenators
Design
Cohort
Follow-up
During clinical perfusion

Membrane oxygenators were associated with fewer microemboli than bubble devices; hypothesis-generating and should not yet change practice.
Does the type of oxygenator (membrane vs. bubble) affect gas transfer and gaseous microemboli production during open-heart surgery?
Membrane oxygenators produce significantly fewer gaseous microemboli than bubble oxygenators during open-heart surgery.
