Comparison of Three Methods of Hemoglobin Monitoring

University of California, San Francisco20 enrolled

Overview

The purpose of this study is to compare the hemoglobin results obtained with 1) the HemoCue™, 2) the Masimo SpHb™, and 3) the UCSF Clinical Laboratory. The goal is to determine if these three values differ from each other during various levels of blood loss in the clinical care of patients for spine revision and hip revision surgery.
