Management of Reticulocytosis with Dropping Hemoglobin Post-Cesarean Section

Initial Assessment

Accurately measure cumulative blood loss using volumetric and gravimetric techniques rather than estimation, as blood loss is frequently underestimated during cesarean section 1
Obtain immediate laboratory tests including complete blood count with hemoglobin and reticulocyte count, coagulation studies, group and screen, and venous blood gas for rapid hemoglobin measurement and lactate (>2 mmol/L indicates shock) 2

If abnormal bleeding is recognized (>1000 ml after cesarean delivery), immediately assemble a multidisciplinary team including obstetrician, anesthetist, and senior midwife 2
Administer tranexamic acid 1g IV (over 10 min) within 3 hours of bleeding onset; if bleeding continues after 30 min or restarts within 24 hours, give a second 1g dose 1

For hemoglobin <70 g/L, red blood cell transfusion is indicated 2
For hemoglobin 70-80 g/L, consider transfusion if the patient has cardiac disease 2
If coagulation tests are not available and bleeding is ongoing after four units of RBC, administer four units of FFP and maintain a 1:1 ratio of RBC-FFP until coagulation results are available 2
If fibrinogen is <3 g/L (especially <2 g/L) with ongoing bleeding, administer cryoprecipitate or fibrinogen concentrate 1, 2
Platelet transfusions are rarely required and should only be given once the platelet count is known 2

Cell salvage should be considered if abnormal bleeding occurs during cesarean section, using a leucocyte filter for autotransfusion of processed blood 2, 3
While routine use of cell salvage during cesarean section is not supported by evidence, it is recommended in cases of significant bleeding 4, 5

Hypofibrinogenaemia (defined as Clauss fibrinogen <2 g/L) is the most common factor deficiency in postpartum hemorrhage, occurring in 5% of cases at 1000 ml blood loss and 17% at 2500 ml 1
Point-of-care testing is preferred over laboratory testing during obstetric hemorrhage due to faster results 2

Continue monitoring hemoglobin levels until stabilized 2
Consider iron supplementation for ongoing anemia management 2
Implement strategies to minimize iatrogenic anemia, including limiting blood sampling by using small-volume tubes 1
