Comparative StudyThe relationship between extracorporeal circuit prime, albumin, and postoperative weight gain in children.
This study evaluated postoperative weight gain in children who received albumin versus crystalloid prime for cardiopulmonary bypass (CPB). ⋯ Data suggest that adding albumin to the EC circuit prime and minimizing the prime volume will result in less postoperative weight gain. Further prospective study with a larger sample is warranted to determine whether albumin prime offers other clinical benefits.

A novel alpha 2-adrenoceptor antagonist attenuates the early, but preserves the late cardiovascular effects of intravenous dexmedetomidine in conscious dogs.
To test the hypothesis that L-659,066, a peripherally acting alpha 2-adrenoceptor agonist, will abolish the early pressor response but preserve the late depressor action of intravenous dexmedetomidine in conscious, unsedated dogs. ⋯ L-659,066 prevents the immediate pressor effects of 5 micrograms/kg of intravenous dexmedetomidine but preserves the majority of the late beneficial cardiovascular effects of this selective alpha 2-adrenoceptor agonist in conscious dogs.

Effect of mild hypothermia during cardiopulmonary bypass on erythrocytic hemoglobin oxygen delivery.
To observe and define the degree of change in hemoglobin oxygen affinity induced by hypothermic extracorporeal circulation (ECC). ⋯ Mild hypothermia to 32 degrees C during ECC does not result in in vivo alterations in oxyhemoglobin dissociation and thus does not induce changes in oxygen delivery to peripheral tissues. However, oxygen usage appears to be markedly increased after cardiopulmonary bypass.
