We examined the clinical characteristics and outcomes by comparing patients with precipitous labor and those with labor of normal duration in 0 and two-parous singleton pregnant women. We retrospectively examined our cases of precipitous labor to identify the clinical significance and perinatal outcomes following precipitous labor in singleton vertex deliveries.Ī retrospective population-based study was conducted comparing women with singleton precipitous labor and those with labor of normal duration. Precipitous labor is defined as expulsion of the fetus within less than 3 hours of commencement of regular contractions. The restriction in the practice of episiotomy and the use of active management can therefore be established as key measures that professionals can modify in order to reduce blood loss during precipitate labour and to improve these mothers' postpartum period. The average loss of haemoglobin was 1.0 g/dL (standard deviation =0.92). Performing active management emerges as a protective factor against increased blood loss (-0.23 p<0.001).
PRECIPITATE LABOUR MANUAL
The main outcome variable was intrapartum blood loss.īy making use of multivariate analysis, the risk factors independently associated with higher blood loss (g/dL) during precipitate labour were nulliparity (0.38 p<0.001), higher antepartum haemoglobin levels (0.23 p<0.001), higher gestational age (0.06 p<0.001), manual removal of the placenta (0.92 p=0.004) and the use of episiotomy (0.34 p<0.001). Dead foetus antepartum gestations, twin gestations and labour induction were excluded from the analysis. This was an observational, analytical retrospective cohort study based on a total sample of 742 women with vaginal delivery whose duration was less than 180 minutes, during the period 2010-2014. Therefore, the objective of this study was to determine the risk factors associated with blood loss produced in precipitate labour. However, preventive measures that may be effective in reducing blood loss in this type of delivery are still unknown. Precipitate labour is related to the appearance of postpartum haemorrhage due to posterior uterine atony.
