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.
