Autologous transfusion in obstetrics.

Area of Science:

• Obstetrics and Gynecology
• Transfusion Medicine
• Maternal-Fetal Medicine

Background:

• Autologous transfusion involves collecting a patient's own blood for later use.
• Its safety and impact on fetal well-being during pregnancy require thorough assessment.
• Elective lower segment Caesarean section (LSCS) provides a context for evaluating this procedure.

Purpose of the Study:

• To evaluate the safety of autologous blood collection in pregnant women undergoing Caesarean section.
• To determine the effects of this blood collection procedure on fetal hemodynamics.
• To assess maternal and fetal outcomes associated with autologous transfusion during pregnancy.

Main Methods:

• A prospective study was conducted on obstetric patients scheduled for elective LSCS.
• Continuous cardiotocograph monitoring was employed during blood collection.
• Fetal hemodynamics were assessed using Doppler blood flow ultrasound before and after the procedure.

Main Results:

• Cardiotocography revealed no instances of fetal deceleration or increased uterine activity.
• A statistically significant difference (p=0.035) was observed in the umbilical artery pulsatility index (PI) before (0.9560) and after (0.0820) blood collection.
• These findings suggest no immediate adverse hemodynamic impact on the fetus.

Conclusions:

• Autologous blood collection for transfusion appears to be a safe procedure for both pregnant women and their fetuses.
• Despite demonstrated safety, autologous transfusion is an underutilized option among pregnant women.
• Further research may be needed to understand the reasons for the low uptake of autologous transfusion in obstetric patients.
