The effect of pre-operative autologous blood donation self-transfusion on hormone and postpartum convalescence in Lying-in women.

The aim of the study is to investigate the feasibility of pre-operative autologous blood donation (PABD) self-transfusion on the postpartum recovery and the endocrine in lying-in women. The PABD is carried out on 70 pregnant women who have high risk of postpartum hemorrhage. Those 70 subjects were divided into three groups: 33 cases of PABD self-transfusion during the Cesarean section; 16 cases of PABD self-transfusion as a physiological means and 21 cases without transfusion. Serum levels of Estradiol (E2), Progesterone (P), Prolactin (PRL) hormone are evaluated 48 hours before and after labor; Postpartum colostrum timing, milk yield, short term and long term uterine contraction are observed among the cases. No significance were observed among the three groups on E2, P, PRL hormone 48 hours before and after labor. The PRL concentration in PABD self-transfusion group is higher than that in the group without self-transfusion 48 hours after labor. Using different PABD self-transfusion strategies, significant difference of the initial milk yield time were observed in the three groups (F=6.035 P=0.004), but the milk yield is no significant different on second day and third day. The self-transfusion of PABD has little influence on uterine contraction. For the women who underwent Cesarean Section, the PABD self-transfusion is conducive to the increase of PRL level. The PABD self-transfusion advances the commencement time of milk yield, while with little effect on neither milk yield volume nor uterine contraction.
