Summary

Autologous blood collection for transfusion during pregnancy is safe for both mother and fetus, with no adverse effects noted on fetal monitoring. This procedure, however, is not widely chosen by expectant mothers.

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.
