About

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).

Full description

We have completed a study with 20 patients using the latest version of the SpHb monitor software and finger sensor.

The purpose of this study is to assess the accuracy of the SpHb reading as it relates to a standard laboratory hemoglobin value (tHb) following the digital block.
