Evaluation of risk factors in women with puerperal genital hematomas

Aim: Our aim was to assess the incidence and risk factors of the puerperal genital hematomas (PGH).Methods: We retrospectively reviewed recorded cases of PGH at Zekai Tahir Burak Research and Training Hospital, Ankara, Turkey, between January 2010 and 2014. Next three patients were chosen as control group.Results: There were 47 cases of PGH with an incidence of 1 in 762 deliveries. Patients with PGH were younger, more likely to be nulliparous and had a greater weight gain during pregnancy than the control group. Patients with PGH had a longer first and second stage of labor than the control group. Mediolateral episiotomy and operative delivery were more frequently performed in patients with PGH than the control group. Neonates born to mothers with PGH were heavier than the control group (3525428 versus 3325 +/- 579; p=0.031). In the logistic regression model, nulliparity (OR: 8.68, 95% CI=2.96-25.3), instrumental delivery (OR: 7.96, 95% CI=1.37-49.0) and mediolateral episiotomy (OR: 6.67, 95% CI=2.61-17.1) were factors which had an independent impact on risk of PGH.Conclusions: Nulliparity, instrumental delivery and mediolateral episiotomy are the main risk factors for hematomas.
