Evaluation of the Accuracy of the Masimo Pulse-Hemoglobin-Meter Monitor in Surgical Patients
- Conditions
- Accuracy of Non-invasive Hemoglobin Monitor
- Registration Number
- NCT01304550
- Lead Sponsor
- University of California, Davis
- Brief Summary
This is a retrospective comparison of hemoglobin measurements obtained by arterial blood gas analysis and the Masimo Continuous Hemoglobin Monitor
- Detailed Description
The chief objective of this study is to internally validate the accuracy of the Masimo SpHb (TM) technology as compared to our laboratory measurement of Hb. We have been using the Masimo SpHb monitor on patients who underwent open heart surgery, hepatic resection, kidney transplant and aortic aneurysm repair since January 2009. These patients also had hemoglobin concentration measurements as part of the arterial blood gas analysis performed by our laboratory to evaluate intraoperative ventilation and electrolyte changes. We will collate the laboratory measurements with the Masimo SpHb values documented in the anesthetic records.
Recruitment & Eligibility
- Status
- COMPLETED
- Sex
- All
- Target Recruitment
- 48
- Patients who had indwelling arterial catheters placed for surgeries that involved major blood loss and who had serial hemoglobin concentration measurements for their surgeries, since January 2009. This will represent approximately 50 patients.
- Inclusion criteria are patients undergoing major surgery from January 2009 - April 2009, who had continuous hemoglobin pulse oximetry readings form the Masimo SpHb monitor and serial hemoglobin concentration measurement from the lab. Patient who did not have these studies will be excluded.
