This project is a prospective, observational study aimed to predict bleeding using hemoglobin trends measured non-invasively in patients undergoing elective cesarean delivery at the George Washington University Hospital.~The primary outcome is trend in hemoglobin measurement, at which additional interventions are required to control hemorrhage. The overall goal is to be able to determine a threshold point in which a drop in the hemoglobin level indicates severe bleeding in anticipation of postpartum hemorrhage. Through the observation of the continuous monitoring of hemoglobin across all participants and correlating those with severe hemorrhage to the magnitude of drop or time of drop, this could potentially optimize the hemorrhage protocol and might limit the need for blood transfusion and decrease maternal mortality and morbidity.
This project is a prospective observational study aimed to assess the use of non-invasive hemoglobin measurement in anticipating postpartum hemorrhage and predicting estimated blood loss. The non-invasive hemoglobin device is the Radical-7 Pulse CO-Oximeter which is a spectrophotometer manufactured by Masimo, Inc. Participants in the study will be undergoing a cesarean delivery at the George Washington University Hospital and during delivery the patient will wear the device on their fingertip so that hemoglobin measurements can be continuously recorded. No changes from routine medical management will occur during the study.
