Abstract
Postpartum hemorrhage (PPH) contributes significantly to maternal morbidity and mortality. The use of cell salvage has been implemented in operating rooms across the world, but only a limited number of institutions have protocols for use of cell salvage during vaginal hemorrhage at the time of vaginal delivery. Observations suggest that blood salvaged from vaginal delivery is comparable to blood salvaged during cesarean delivery. Using pre-validated protocols of cell salvage, we sought to assess the feasibility and potential benefit of implementing cell salvage in our Labor and Delivery unit in all patients at high risk of hemorrhage. This was a prospective pilot study conducted from April 2022 to December 2022 on the Labor and Delivery floor at Mount Sinai Hospital in New York City. A total of 50 participants were identified for cell salvage after vaginal delivery during the study period.The mean age of participants was 34.4 years (SD 5.5).We utilized acell salvage technique at the time of vaginal delivery in patients at high risk of PPH. We employed simple descriptive statistics and examined sums and percentages (and means and standard deviations, where appropriate). A simple equation was used to determine the average cell salvaged volume in each delivery and describe potential values. The HEMAsavR™device (Ecomed Solutions, Mundelein, IL, USA) was used as a standby system to be used at the time of the vaginal delivery. Fifty participants were identified for the cell salvage protocol as described. Despite a diversity of clinical risk factors, the sample consisted ofpredominately non-Hispanic White patients. The mean quantitative blood lossof cell salvaged samples was 157.2 mL(SD 153.0). We identified that, on average, >33% of vaginally shed blood could be used for cell salvage and improve patient blood management. The implementation of cell salvage in our Labor and Delivery unit was feasible and easy to perform. We identified that a significant volume of blood would be available for cell salvage. Further studies should be done to evaluate the benefit of cell salvage to improve postpartum recovery.
