Blood Volume Analysis of Total Hip Arthroplasty Patients Under Hypotensive Anesthesia
In Brief
A clinical study evaluating 1mL of I-131 Human Serum Albumin is injected prior to the measurements for Blood Volume Analysis. Completed, enrolled 14 participants across 1 site.
Detailed Summary
Hypotensive Anesthesia is a type of regional anesthesia performed routinely at our hospital. This type of anesthesia reduces the average arterial pressure. Benefits include reduced bleeding and lower risk of blood clots. The purpose of this study is to determine the effect of intravenous fluids administered with hypotensive anesthesia on your blood volume. With this parameter we will be able to understand how much of your blood is lost because of bleeding and how much of the drop is related to dilution. Study hypothesis: Hemodilution associated with intravenous fluid substitution during hypotensive anesthesia results in decreased postoperative hemoglobin (Hb) levels
