Autologous transfusion in obstetrics
1Department of Obstetrics & Gynaecology, Singapore General Hospital, Singapore.
Aim Of Study:
To assess the safety of blood collection for autologous transfusion in pregnant women and the effects of the procedure on the fetus.
Method:
Prospective study involving obstetric patients undergoing elective lower segment Caesarean section (LSCS) between 1993 and 1994 were recruited for autologous transfusion. Continuous cardiotocograph monitoring was carried out throughout the duration of the procedure and the fetal haemodynamics was studied before and after by doppler blood flow ultrasound.
Results:
The results show that there was no fetal deceleration or increased uterine activity as monitored by cardiotocography. The mean pulsatility index (PI) for the umbilical artery before the procedure was 0.9560 and after was 0.0820 which is a significant difference (p value = 0.035).
Conclusion:
Autologous blood collection seems to be a safe procedure for both the mother and the fetus. However, autologous transfusion remains an unpopular choice amongst pregnant women.
