Implication

Comparative study reveals favorable peripheral perfusion and platelet preservation with extreme haemodilution in bypass surgery, indicating its viability without increasing bleeding risks.

Key Points

To evaluate the impact of intra-operative normovolaemic extreme haemodilution compared to haemic priming during cardiopulmonary bypass on immediate post-operative recovery in coronary artery bypass grafting.
Evaluated 140 patients undergoing coronary artery bypass grafting, comparing 70 patients managed with normovolaemic moderate and extreme haemodilution to 70 control patients receiving a haemic prime in the heart-lung machine.
Tracked post-operative chest tube bleeding, transfusion and fluid administration, haemodynamics, arterial oxygenation, serum creatinine, and peri-operative myocardial infarctions, analyzing re-exploration cases (N=8) as a distinct subgroup.
Re-exploration for severe bleeding occurred in 5.7% of all patients (4 of 70 haemodilution patients vs. 4 of 70 controls), with chest tube drainage, haemoglobin levels, and transfused blood or fluid volumes showing similar distributions across groups.
Haemodiluted patients displayed significantly faster opening of peripheral circulation via skin temperature rise, consistently lower central venous pressure, lower serum creatinine levels, and significantly higher blood platelet counts.
Arterial blood oxygen tension was slightly lower in haemodiluted patients around respirator weaning, while peri-operative myocardial infarction rates showed no essential differences between cohorts.
