Plasma heparin activity and antagonism during cardiopulmonary bypass with hypothermia.
Plasma heparin activity in 11 patients undergoing open-heart surgery was measured by comparing thrombin time of patient plasma to thrombin time of plasma containing known heparin concentrations. Although all patients received 300 units/kg of heparin, their initial plasma heparin levels varied significantly, from 1.8 units/ml in lighter petients to 3 units/ml in heavier patients. During hypother...
متن کاملIncreased circulating bradykinin during hypothermia and cardiopulmonary bypass in children.
To determine whether cold could activate the kallikrein-kinin system in vivo as it does in vitro, the circulating systemic concentrations of bradykinin were serially measured in 10 cyildren with congenital diseases of the heart undergoing corrective cardiac surgery. Bradykinin was measured by radioimmunoassay in blood samples obtained before, during and after profound hypothermia (to 18 degrees...
متن کاملRewarming, ultraprofound hypothermia and cardiopulmonary bypass.
Rewarming, a key event in resuscitation from accidental, experimental and clinical hypothermia, is sometimes followed by neurologic, cardiac, and respiratory sequelae and may lead to death. The rate of rewarming has been implicated but not quantified as etiologic in these sequelae. Under anesthesia fifteen dogs were cannulated and connected to an extracorporeal circuit for oxygenation, core co...
متن کاملExperience with prostacyclin in cardiopulmonary bypass in dog and man.
The activation and disruption of platelets resulting from contact with bypass equipment is responsible for bleeding problems after open-heart surgery and for vascular injury leading to cerebral damage. This paper presents experimental and clinical evidence for the benefits of the preservation of platelets by prostacyclin (PGI2) during cardiopulmonary bypass operations. Work with dogs showed tha...
متن کاملHypoxaemia during cardiopulmonary bypass.
For cardiopulmonary bypass during open-heart surgery we use a bubble oxygenator and a technique of haemodilution and moderate hypothermia. During the course of routine perfusion we have observed arterial desaturation in a number of patients and in five patients the desaturation was marked (SaO2<85%)'. The low arterial oxygen saturations occurred mainly in the rewarming period. This report is of...
