Prophylactic parenteral tranexamic acid significantly reduces blood loss during and after caesarean section, reveals study

The women were randomised into two groups: the intervention group (n = 142) that received intraoperative tranexamic acid with routine post-delivery oxytocin injection and the control group (n =142) that received placebo with routine post-delivery oxytocin. Blood loss was assessed both intra and post-operatively using a standard technique. RESULTS: The mean intraoperative blood loss was significantly lower in the intervention group compared to the control group (435.9±34 vs. 918±258.7, P=0.036).

Similarly, the postoperative blood loss within twenty-four hours of surgery was significantly less in the intervention compared to the control group (232.71±67.4 vs. 717±317.6, P=0.031). The incidences of postoperative anaemia and blood transfusion intra or postoperatively were also significantly less in the intervention group compared to the control group (33.2% vs. 48.6; RR = 0.623; 95% CI = 0.46-0.84; p = 0.002, and 6.3% vs 24.6%: RR = 0.257; 95%CI = 0.13-0.52; P= < 0.001, respectively). There were no differences in the incidences of maternal and neonatal complications. The use of prophylactic parenteral tranexamic acid significantly reduces blood loss during and after caesarean section. It is therefore recommended in our obstetric practice as it has the potential to reduce the incidence of postpartum anaemia.
