“…The reason for studying these CRs was that 20 micron filtered CRs have been shown to be superior for gaseous and particulate microemboli removal compared to other sizes.u• 16 There is an increase in arterial line gaseous microemboli counts when the blood from a CR is returned to the oxygenator. 16 The importance of removing these gaseous microemboli is that they are mostly nitrogen which is relatively insoluble in blood and, as such, is more likely to cause tissue damage. 17 The various methods of gaseous microemboli detection have been reviewed.…”

Five commercially available cardiotomy reservoirs (CR) were tested to determine: Gaseous microemboli removal efficiency Manufacturer contaminant levels Blood hold-up volume The gaseous microemboli were detected by a doppler type ultrasonic detector. Manufacturer contaminant levels were counted by flushing each CR with filtered water and collecting the contaminants on a filter paper. This was then examined under a light microscope and size and counts were taken. The blood hold-up volume was determined by finding the difference in volume in a cylinder between flowing through the CR and bypassing it. The lntersept and BST-l CR were found to be significantly more efficient at removing the gaseous microemboli. All the CR had a large number of contaminants which included a particle count range from 10-278 greater than 100 microns. The lntersept CR had less hold-up volume then the others.

“…The postoperative scans of a group of children undergoing bypass with a membrane oxygenator showed less abnormalities than those in whom a bubble oxygenator was used. Comparative studies have shown membrane oxygenators to be superior with respect to decreased counts of microemboli, 36 ' 37 increased urinary output, 41 ' 43 enhanced tissue perfusion, 41 ' 42 reduced loss of platelets, 41 ' 44 " 46 and less postoperative bleeding, 41 ' 4247 ' 48 particularly after long procedures. It is not surprising that membrane oxygenators are widely used today and are responsible for less trauma to the blood and improved outcome.…”

Neonatal cardiopulmonary bypass—a review of current practice in North America

One of the most challenging applications of cardiopulmonary bypass is corrective cardiac surgery in the neonate. The small size and high metabolic demand of these patients require miniaturized but efficient equipment. Even with the most advanced components, the volume required to prime the perfusion circuit is typically more than twice the blood volume of a neonate. Neonates have limited cardiac and pulmonary reserves and, therefore, great care is required to preserve those organs that have often already been subjected to hypoxemia, congestive heart failure, or low cardiac output prior to surgery. There is a tendency toward extravascular movement of fluids in newborns subjected to bypass that can adversely affect outcome. Careful monitoring and precise management of perfusion are essential to a successful procedure and optimal recovery of these patients.
