Liver Enzymes and Fluid Balance Following Colorectal Surgery

The use of epidural anesthesia and postoperative analgesia influences fluid balance following colorectal surgery.

Markers such as BNP (brain natriuretic peptide) and liver function enzymes can estimate intravascular fluid load and predict outcome after colorectal surgery.

Inclusion Criteria:

• Patients undergoing colorectal surgery

Exclusion Criteria:

• Severe cardiac failure Severe renal failure Severe liver failure
