Different Doses of Sublingual Misoprostol versus Methylergometrine for the Prevention of Atonic Postpartum Haemorrhage.

objectiveIn the poor underdeveloped countries, anaemia is very common in pregnant women. Maternal mortality is four times higher in severely anaemic women than non-anaemic ones and postpartum haemorrhage (PPH) is the most common cause of death. Its main cause is uterine atony, which accounts for more than 70%. The objective of this study is to evaluate the use of sublingual misoprostol in different doses of 600, 800 and1000μg in management of the third stage of labor, with regards to blood loss and incidence of atonic postpartum haemorrhag (APPH). STUDY

designDouble blind randomized controlled study

methodsOne thousand and two hundred parturient were studied in a control and three study groups, each composed of 300 women. Methylergometrine 0.2 mg IM injection and sublingual misoprostol 600, 800 and 1000 μg tablets were given to women in control and the three study groups respectively, immediately after delivery. OUTCOME MEASURES: Duration of the third stage of labour, Blood loss in the third stage of labour, Outcomes in anaemic compared to non-anaemic women, Incidance of atonic postpartum haemorrhage in different groups, Haemoglobin deficit after 24 hrs of delivery, Changes in the women's blood pressure during the study, Side effects of the drug, and, Women's acceptability of sublingual misoprostol administration.

resultsOnly significant reduction in blood loss and haemoglobin deficits were seen in the third stage of labour and after delivery in women used misoprostol doses of 800 μg and 1000 μg. The incidences of PPH in studied women and controls were almost similar, ranging between 2 and 3%. Similar results were seen in anaemic and non-anaemic women with a higher incidence of APPH in the non-misoprostol user anaemic women. Side effects of the drug were dose related.

conclusionMisoprostol in high dose may be used for managing third stage of labour to reduce maternal morbidity and mortality due to APPH particularly, in the poor underdeveloped countries where, facilities to deliver in health centers, purchase and store the oxytocic ampoules or medically trained persons are not readily available in all places. Benefits of large dose misoprostol outweigh its side effects.
