Treatments for secondary postpartum haemorrhage

Jo Alexander, Peter W Thomas, Jill Sanghera

Secondary postpartum haemorrhage is any abnormal or excessive bleeding from the birth canal occurring between 24 hours and 12 weeks postnatally. In developed countries, two per cent of postnatal women are admitted to hospital with this condition, half of them undergoing uterine surgical evacuation; in developing countries it is a major contributor to maternal death. To evaluate the relative effectiveness and safety of the treatments used for secondary postpartum haemorrhage. We searched the Cochrane Pregnancy and Childbirth Group trials register (May 2001), the Cochrane Controlled Trials Register (The Cochrane Library, issue 2, 2001), MEDLINE (back to 1966) and EMBASE (back to 1988). The National Research Register was also searched. The reference lists of trial reports and reviews were searched by hand. Where possible, further sources were sought from the first named authors of the papers identified. All randomised or quasi randomised comparisons between drug therapies, surgical therapies and placebo or no treatment for the management of secondary postpartum haemorrhage occurring between 24 hours and three months following a pregnancy of at least 24 weeks gestation. Reports of possibly eligible studies were scrutinised by two investigators. The third investigator acted as an advisor/arbitrator. Of the 45 papers identified, none met the inclusion criteria. No information is available from randomised controlled trials to inform the management of women with secondary postpartum haemorrhage. This topic may have received little attention because it is perceived as being associated with maternal morbidity rather than mortality in developed countries; it is only recently that the extent and importance of postnatal maternal morbidity has been recognised. A well designed randomised controlled trial comparing the various drug therapies for women with secondary postpartum haemorrhage against each other and against placebo or no treatment groups is needed.
