ABSTRACT
BACKGROUND:
The association between an incomplete placenta and postpartum haemorrhage (PPH) is well documented; however, the significance of ragged or incomplete membranes has not been explored as an independent risk factor for PPH.AIMS:
To explore the association between the completeness of the amniotic and chorionic membranes and the risk of PPH, independent to placental status. MATERIALS ANDMETHODS:
37 176 birth records were retrospectively extracted from the period 1 July, 2008 to 30 June, 2016 from the databases of two public hospitals in Melbourne, Australia. Following application of specific exclusion and inclusion criteria, including non-complete placentas, 5718 records were available for analysis. These records were grouped based on membrane status (complete, ragged or incomplete) and outcome (PPH or no PPH).RESULTS:
Primary PPH rates were 14.8% in women with complete membranes, 20.2% in women with ragged membranes and 25.8% in women with incomplete membranes. Following statistical adjustment, the risk ratios for PPH were 1.32 (95% CI 1.15-1.50) and 1.70 (95% CI 1.41-2.04) in women with ragged and incomplete membranes, respectively.CONCLUSIONS:
Both ragged and incomplete membranes were found to be independent risk factors for primary PPH. This previously un-discussed association has the potential to influence clinical practice changes, particularly with regard to the ongoing clinical relevance and use of the terms 'ragged' and 'incomplete' membranes.Palavras-chave
