An interventional study of Masimo SpHb™ monitor in Placenta Previa, sponsored by Seoul National University Bundang Hospital. Completed at 1 site in Korea, Republic of. Open to female participants aged 20 Years to 50 Years. Per ClinicalTrials.gov, last updated 2019-01-17.
Sponsored by Seoul National University Bundang Hospital · Not applicable, Interventional, and Diagnostic
Non-invasive hemoglobin monitoring will be performed in patients who underwent cesarean section with placenta previa and this will be compared with actual laboratory findings.
The investigators will investigate whether noninvasive hemoglobin monitoring can adequately reflect the massive bleeding that occurs within a short period of time and find out if it matches the actual laboratory findings.
Exclusion Criteria:
Device: Masimo SpHb™ monitor
Attach the Masimo Rainbow SET® Radical-7 ™ pulse oximeter probe to the third or fourth finger and perform a Masimo SpHb ™ monitor.
