13. Unaccounted blood loss in operations using cardiopulmonary bypass.
Typically, blood loss after operations requiring cardiopulmonary bypass is estimated from the sum of blood on sponges and drapes, in the suction system reservoir, and in chest drainage bottles. Prime of the extracorporeal circuit is usually returned to the patient, but no accounting is made of blood remaining in the circuit. In 50 patients, we examined 25 bu

14. In Vivo Survival of Red Blood Cells Processed by a Bubble or Membrane Oxygenator During Cardiopulmonary Bypass Surgery
A dual radioisotope labeling technique was utilized to assess red cell survival differences between cells processed by either a bubble oxygenator (eight patients) or membrane oxygenator (eight patients) in 16 patients undergoing cardiopulmonary bypass surgery. Cells processed by a bubble oxygenator consistently had a shortened survival. The 30-minute recover

15. Full recovery of a patient after oxygenator replacement during open-heart surgery
During an open-heart procedure in a 69-year-old man, a damaged mitral valve was being examined when suddenly the venous return line from the oxygenator of the heart-lung machine became filled with gas. After the venous line had been flushed and cardiopulmonary bypass had been reinstated, the line again filled with gas, and the aortic line also had to be clam

16. PERFUSION FOR MYOCARDIAL REVASCULARIZATION WITHOUT AN ARTIFICIAL OXYGENATOR (New Method to Reduce Surgical Morbidity)
Thirteen patients were submitted to direct myocardial revascularization (saphenous vein graft) without the use of an artificial oxygenator. The perfusion was done by a left ventricle-to-aorta bypass and autogenous oxygenation. Most patients had three grafts implanted plus endarterectomy of the distal right coronary artery. There was one hospital death that w

17. Low-dose heparin versus full-dose heparin with high-dose aprotinin during cardiopulmonary bypass. A preliminary report.
Perfusion during cardiopulmonary bypass with low-dose heparin (activated clotting time, > 180 sec) versus full-dose heparin (activated clotting time, > 480 sec) combined with high-dose aprotinin was evaluated prospectively. Fifteen patients undergoing elective myocardial revascularization were randomly assigned to 1 of 2 groups. No significant differences be
