Accuracy of Non Invasive Hemoglobin Measure by SpHb Device in Post Operative Anemia Diagnosis

Not yet recruiting
Conditions
Anemia
Registration Number
NCT06497335
Lead Sponsor
University Hospital, Angers
Brief Summary

Non invasive Hemoglobin monitoring by SpHb device had been developed to assess Hemoglobin level during hemorrhagic surgery. It's accuracy to detect post operative anemia on a single post operative measure has been recently demonstrated on a cohort of post operative orthopedic patient and it's routine use has been generalized to other surgical department. This study aims to valid these finding on a cohort of post operative patients from gynaecological department.
