Official title
Comparison of Three Methods of Hemoglobin Monitoring in Patients Undergoing Spine or Hip Surgery
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will further investigate the Masimo SpHb \[FDA Approved\] continuous non-invasive hemoglobin monitor in spine surgery patients. (See NCT00792597) We will investigate the effect of enhanced circulation to the finger (which will be attached to the sensor) following a local injection (digital block) of lidocaine (an FDA approved local anesthetic), and assess the accuracy of the SpHb reading as it relates to a standard laboratory hemoglobin value (tHb).
