The development of surgical treatment for certain types of congenital heart disease not only has resulted in a number of neurological complications but has also emphasized the frequency with which such . Three types of oxygenators had evolved by the vertical screen oxygenator of Gibbon and Kirklin, the bubble oxygenator of DeWall and Lillehei, and a rotating disc oxygenator developed by Jerome . The simple design of the bubble oxygenator relied on a hydrostatic force per unit area caput from the patient to the blending chamber connected by the venous line to the right atrium or vein cava. Bubble oxygenators besides have the heat money changer downstream from the bubble . biologic oxygenator of this type are that it allows a massive surface area for oxygena-tion of blood, causes minimal trauma to con-stituents of the blood, is a filter, and prob-ably carries out some detoxifying function. In the remainder of the extraconporeab sys-tem there is included a bubble trap to safe-guard against air embolism .

Hazard of Antifoam Emboli from a Bubble Oxygenator By A. Cassie, A. Riddell and P. Yates Topics: Articles. The clinical problem of antifoam embolism has not been possible to appraise.

It is our opinion that although such embolism occurs it is seldom of clinical importance. SUMMARY i. The performance of a low prime pneu- matic pump bubble oxygenator in experimental animals and man has been appraised.

The method of oxygenation used in the unit in which this work was done is the DeWall type of bubble oxygenator. One of the greatest drawbacks to the use of the bubble oxygenator, however, has been the difficulty in defoaming blood adequately after oxygenation.

This suggested that fragments of polyvinyl chloride might be the particles in the emboli. Another possible source was the antifoam agent used in the bubble oxygenator. Scanning electron microscopy x-ray.

At the top of the cylinder, arterialized bubble-rich blood passed over stainless steel wool coated with silicone antifoam; it then traveled through a long helical settling coil to allow bubbles to rise slowly and exit the blood.

Fig. Richard DeWall and Vince Gott look at the first commercially manufactured sterile bubble oxygenator. Bubble oxygenators cause a continuous and progressive loss of protein, including the release of denatured proteins into the circulation where they may have biological effects.

Another possible source was the antifoam agent used in the bubble oxygenator. Scanning electron microscopy x-ray microprobe analysis of the foreign material within capillaries of several organs showed it to be strongly positive for silicon but not for chlorine.

At the top of the cylinder, arterialized bubble-rich blood passed over stainless steel wool coated with silicone antifoam; it then traveled through a long helical settling coil to allow bubbles to slowly rise and exit the blood.

Two important components in the Lillehei-DeWall bubble oxygenator were the tubing and the silicon antifoam.
