Comparison of Three Methods of Hemoglobin Monitoring
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.

|Official Title:||Comparison of Three Methods of Hemoglobin Monitoring in Patients Undergoing Spine Revision or Hip Revision Surgery.|
- See description below [ Time Frame: A minimum of three differences recorded during surgery ] [ Designated as safety issue: Yes ]Primary outcome is based on the difference between SpHb (Masimo SpHb™ continuous hemoglobin reading ) - tHb (laboratory hemoglobin determination).
- See description below [ Time Frame: A minimum of three differences recorded during surgery ] [ Designated as safety issue: Yes ]Secondary outcome is based on the difference between a HemoCue™ derived hemoglobin determination - laboratory hemoglobin determination.
