Primary outcomePrimary: The Hemoglobin (in g/dl) Levels — 12.2; 12.0; 11.9; 11.8 g/dl
Summary
The current study investigates the effect of hypotensive anesthesia on patient hemoglobin levels during primary total knee arthroplasty. Considering that because of the tourniquet there is no blood loss during the first 60 minutes of the procedure changes in hemoglobin during the first 60 minutes should be primarily related to decrease in blood pressure and secondary to fluid loading during hypotensive anesthesia.
