Doctorvaladan, S, et al; Accuracy of Blood Loss Measurement during Cesarean Delivery. Am J Perinatol Rep 2017;7e93-e100.

This study aims to compare the accuracy of visual, quantitative gravimetric, and colorimetric methods used to determine blood loss during cesarean delivery procedures employing a hemoglobin extraction assay as the reference standard. During cesarean delivery, measuring blood loss using colorimetric image analysis is superior to visual estimation and a gravimetric method. Implementation of colorimetric analysis may enhance the ability of management protocols to improve clinical outcomes.
