A low priming volume oxygenator for bloodless priming in cardiopulmonary bypass.
The oxygenator described here arose out of the need to dispense with homologous blood in animal perfusions. It was considered that this could best be attained with an oxygenator having a priming volume sufficiently small to allow the use of isotonic solutions without undue dilution and consistent with full gas exchange and adequate temperature control. It was recognized that modifications to ex...
متن کاملA smaller priming volume oxygenator for the Melrose-N.E.P. heart/lung machine.
One direction of the development of oxygenators for extracorporeal circulation has been an extension of their versatility by relating priming volumes to flows required. Bubble oxygenators, disc oxygenators of the Kay-Cross type, are easily altered in size, and Ross (1960) has developed two smaller versions of the Guy's Hospital model. In some small patients the extracorporeal circuit may be mor...
متن کاملRinger-lactate solution as a priming fluid for the disc oxygenator.
Gadboys, Slonim, and Litwak (1962) reported what is now known as the homologous blood syndrome, which stimulated work on a substitute for blood in open-heart surgery, especially for the priming of the heart-lung machine. The homologous blood syndrome was noted in experimental animals and consisted of hypotension on commencing cardiopulmonary bypass, with early thrombocytopenia, leucopenia, sequ...
متن کاملUse of frozen blood.
Frozen blood is most easily and economically prepared using high glycerol (40 percent). Storage is at —80° in a mechanical freezer. Thawing must be rapid and washing can be carried out with low electrolyte sugar solutions and agglomeration or with high electrolyte solutions and continuous flow centrif ugation. These processed cells have many advantages not found in raw routinely stored blood. ...
متن کاملImmunological studies in frozen shoulder.
This immunological study of 40 patients with frozen shoulder showed a pretreatment increase in immune complex levels, C-reactive protein, and decreased lymphocyte transformation to phytohemagglutinin and concanavalin A compared to a control group. Repeat estimations after 8 months showed that values tended to approach control levels.
