Abstract
The purpose of this study was to determine the effect of placenta extraction from exteriorized uterus versus placenta extraction from non- exteriorized uterus on blood loss during caesarean section (CS). It was a randomized control study in which 98 women undergoing caesarean section were allocated randomly to either the placental delivery from exteriorized uterus or placental delivery from non-exteriorized uterus. The main outcome measure was intraoperative blood loss, and Intention to treat analysis was used. More participants in the non-exteriorized placenta removal group had blood loss ≥500mls (P-value <0.001). Logistic regression showed about 5times likelihood of having blood loss of 500mls or more in the non-exteriorized group (P< 0.001; OR: 5.67; 95%CI: 2.38-13.40). The mean estimated blood loss was 54.1mL less in exteriorized placenta removal group (476.12±160.86 versus 530.20±145.18; P-value = 0.084). The mean changes in haemoglobin concentration in exteriorized and non-exteriorized groups were 0.68±0.19g/dL and 0.74±0.20g/dL; P = 0.131) respectively. This study showed statistically significant difference in blood loss of 500mls or more in the placenta delivery from non-exteriorized compared to the exteriorized group. However, there was no significant difference in the mean blood loss, duration of surgery, and change in haemoglobin between the two groups.
