How effective are cardiopulmonary bypass circuits at removing gaseous microemboli?
An association has been demonstrated between intravascular microemboli and organ injury during cardiopulmonary bypass (CPB). Air may be inadvertently introduced into the venous line during CPB resulting in the formation of gaseous microemboli (GME). We studied the ability of CPB circuits, from five different manufacturers, to remove GME originating from the introduction of air into the venous l...
متن کاملThe effectiveness of low-prime cardiopulmonary bypass circuits at removing gaseous emboli.
During extracorporeal circulation, the patient's blood is siphoned into the extracorporeal circuit (ECC) by gravity or may be assisted kinetically or by vacuum. In all instances, negative pressure is generated in the venous line, which can cause entrainment of air into the ECC at the cannulation site. The typical ECC uses a venous reservoir, membrane oxygenator, and arterial line filter, which ...
متن کاملVacuum-assisted venous drainage and gaseous microemboli in cardiopulmonary bypass.
When conventional gravity siphon venous drainage cannot achieve satisfactory venous drainage during minimally invasive cardiac and neonatal surgeries, assisted venous drainage techniques are needed to ensure adequate flow. One assisted venous drainage technique, vacuum-assisted venous drainage (VAVD), the aid of a vacuum in the venous reservoir, is now widely used to augment venous drainage dur...
متن کاملBlood temperature management and gaseous microemboli creation: an in-vitro analysis.
Gaseous microemboli have been associated with post operative neurological deficits in patients undergoing cardiopulmonary bypass. Creating an optimal perfusion system that minimizes microemboli production and has enhanced abilities to sequester entrained air during the bypass procedure has been an important focus. This study examines the air-handling capabilities of a cardiopulmonary bypass cir...
متن کاملArterial Limb Microemboli during Cardiopulmonary Bypass: Observations from a Congenital Cardiac Surgery Practice.
Gaseous microemboli (GME) are known to be delivered to the arterial circulation of patients during cardiopulmonary bypass (CPB). An increased number of GME delivered during adult CPB has been associated with brain injury and postoperative cognitive dysfunction. The GME load in children exposed to CPB and its consequences are not well characterized. We sought to establish a baseline of arterial ...
