Comparative Study Clinical Trial Controlled Clinical TrialDextran 70 versus donor plasma as colloid in open-heart surgery under extreme haemodilution.
Dextran 70 and donor plasma were compared as colloid in the priming solution during heart-lung perfusion in open-heart surgery. The patients underwent surgery for coronary artery or aortic valve disease. One group of nine patients had plasma in the priming solution, while ten patients received dextran 70. ⋯ Preoperatively the mean values of the colloid osmotic pressure of plasma were 24.2 mmHg and 25.5 mmHg in the plasma and dextran group, respectively. Corresponding figures 45 min after start of perfusion were 13.9 mmHg and 16.9 mmHg, respectively, significantly higher in the dextran group than in the plasma group. The colloid osmotic pressure exerted by dextran was about 9 mmHg during heart-lung perfusion and about 4 mmHg 18 h later.(ABSTRACT TRUNCATED AT 250 WORDS)
