Change in Near-Infrared Spectroscopy (NIRS) Measures with Transfusion by Hemoglobin (Hgb) Threshold Group
In the first 28 days after birth, cerebral saturation (Csat) and mesenteric saturation (Msat) increased after packed red blood cell transfusion, while cerebral fractional tissue oxygen extraction (cFTOE) and mesenteric fractional tissue oxygen extraction (mFTOE) decreased. However, changes in NIRS measures were not significantly different between the high– and low–Hgb threshold groups for Csat, cFTOE, Msat, or mFTOE.
