Conclusion
In conclusion, IPC and IPF have weak correlations with postoperative drainage volumes and the need for blood transfusion. They appear to have little value –if any– in the prediction of postoperative bleeding in patients undergoing CABG. Further research with larger sample size may be required to understand the role of IPs in coagulopathy after surgical procedures, and studies with a prospective design that stratify patients based on various other characteristics may aid the search for other parameters (especially blood indices) that could be utilized to predict excessive bleeding in this patient population.
