Comparison effect of intravenous tranexamic acid and misoprostol for postpartum haemorrhage

BACKGROUND Postpartum haemorrhage (PPH) is the third-most common cause of maternal death in the United States and it is still the first prevalent cause of maternal death in developing countries. Active prevention of haemorrhage with an uterotonic or other new drugs leads to a decrease in postpartum vaginal haemorrhage. The aim of this study was to compare anti-haemorrhagic effect of Tranexamic acid (TXA) and Misoprostol for PPH. PATIENTS AND METHODS In a double-blinded randomised control clinical trial, 200 women were included after Caesarean or natural vaginal delivery with abnormal PPH. They were divided into two equal intervention and control groups. Effect of intravenous TXA and Misoprostol for postpartum haemorrhage was examined. RESULTS The mean age of patients was 26.7 ± 6.5 years which ranged from 14 to 43 years. The sonographic gestational age in the group treated with TXA was 37.7 ± 3.4 weeks and it was 37.4 ± 3.3 weeks for the other group (P = 0.44). The haemorrhage in the TXA and Misoprostol groups was 1.2 ± 0.33 litres and 1.18 ± 0.47 litres, respectively (P = 0.79). The haemoglobin levels after 6-12 hours of labour, in TXA group was more than that of the Misoprostol group, but this difference was not statistically significant (P = 0.22 and P = 0.21, respectively). CONCLUSION Regarding to the superior results in Misoprostol group in one hand and lack of significant differences between two groups in haemorrhage during labour, post-partum haemoglobin level and discharge haemoglobin level, we can state that Misoprostol has no specific preferences to TXA, but more studies with greater population are needed.
