Non-Invasive Measurement of Hemoglobin (Using Pulse Co-Oximetry) in Patients Undergoing Elective Cesarean Delivery

Completed

Conditions studied: Postpartum Hemorrhage

In brief

We aim to assess a new pulse oximeter which measures continuous hemoglobin concentration (SpHb) in healthy patients undergoing elective Cesarean delivery (CS). This patient population often experiences significant blood loss during surgery, and measurements of surgical blood loss are often inaccurate. We will compare measurements of SpHb with estimated blood loss during the perioperative period, and laboratory measurements of hemoglobin at set time intervals during the perioperative and postoperative periods (to evaluate the accuracy of this device's ability to measure continuous SpHb).
