摘　　要：<strong>Background</strong><span><span><span style="font-family:""><span style="font-family:Verdana;"><strong>: </strong>With newer protocols, such as delayed cord clamping, becoming routine practice, determining the potential maternal consequences is important. In particular, establishing normative values for blood loss from the hysterotomy would be helpful in addressing techniques to minimize total blood loss for cesarean deliveries. </span><b><span style="font-family:Verdana;">Objective</span></b><span style="font-family:Verdana;">: Blood loss from the hysterotomy during cesarean delivery has not been reported using quantitative methods. We aimed to quantify the rate of blood loss during cesarean delivery from the hysterotomy between creation and closure. </span><b><span style="font-family:Verdana;">Methods</span></b><span style="font-family:Verdana;">: This single center, prospective, case series was collected in 2018. Women with singleton pregnancies undergoing cesarean delivery at </span></span></span></span><span><span><span style="font-family:""><span style="font-family:Verdana;">≥</span><span><span style="font-family:Verdana;">37 0/7 weeks at Brigham and Women’s Hospital were included. Delayed cord clamping was performed which allowed for quantification of blood loss through gravimetric methods and descriptive statistics were performed. </span><b><span style="font-family:Verdana;">Results</span></b><span style="font-family:Verdana;">: Twenty patients were included. The mean hysterotomy closure delay for cord blood collection was 47 seconds (SD 10.2) and the mean maternal blood volume collected was 110.8 mL (SD 53.4 mL). Blood loss per minute was calculated with a median of 150 </span><span style="font-family:Verdana;">mL/minute (IQR 88.8 mL, 95% CI 109.2 - 190.4 mL). The mean post-operative </span><span style="font-family:Verdana;">hematocrit drop was 4.4%, and there were no blood transfusions. There was a single hysterotomy extension and a quantified blood loss of 413 mL per minute. </span><b><span <strong>Background</strong><span><span><span style="font-family:""><span style="font-family:Verdana;"><strong>: </strong>With newer protocols, such as delayed cord clamping, becoming routine practice, determining the potential maternal consequences is important.
