  Purpose

There is no study hypothesis. The purpose of this study is to compare the accuracy of the: 1) SpHb (Radical 7 Pulse Co-Oximetry with SpHb™) RevF sensor (currently marketed), 2) the SpHb RevG sensor (a new, limited release version), and 3) the Pronto-7 sensor (currently marketed version) in patients undergoing spine surgery.

Study Type: Observational
Study Design: Observational Model: Cohort
Official Title: Comparative Accuracy of Three Versions of Non-Invasive Hemoglobin Monitoring.

Further study details as provided by University of California, San Francisco:

Primary Outcome Measures:
  • Comparison of hemoglobin levels derived by sensor RevF versus sensor RevG versus a hemoglobin derived from a blood sample. A baseline hemoglobin level will be taken from the Pronto-7 hand-held hemoglobin device prior to surgery. [ Time Frame: Two or more measurements during surgery ] [ Designated as safety issue: No ]
    Comparison of hemoglobin levels derived by sensor RevF versus sensor RevG versus a hemoglobin derived from a blood sample. A baseline hemoglobin level will be taken from the Pronto-7 hand-held hemoglobin device prior to surgery.


Enrollment: 10

Study Completion Date: May 2013
Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts
RevF vs RevG vs Pronto-7
Comparison of hemoglobin levels derived by continuous hemoglobin sensor RevF versus continuous hemoglobin sensor RevG versus an intermittent hemoglobin level derived from the Pronto-7 hand-held device versus a hemoglobin derived from a blood sample.

Detailed Description:

The purpose of this study is to compare the accuracy of the: 1) SpHb RevF sensor (currently marketed), 2) the SpHb RevG sensor (a new, limited release version), and 3) the Pronto-7 sensor (currently marketed version) in patients undergoing spine surgery. The results from the three sensors will be compared to a blood hemoglobin level taken intermittently (as a function of the patient's anesthesia care) and analyzed in the UCSF Clinical Laboratories.

This is an observational study.
