Summary

This study examines how doctors give fluids to adults during heart surgery, specifically comparing the use of albumin (a blood product) versus crystalloids (salt solutions). Researchers will review records from 505 patients across multiple hospitals to see what fluids are used, when, and why. The goal is to understand current practices and outcomes, not to test a new treatment.
