ORIGINAL PAPER www.slcog.lk/sljog A Clinical Study of Maternal and Fetal Outcome in Abruptio Placenta - Couvelaire Uterus a Preventable Obstetric Catastrophe Vijayasree M postpartum haemorrhage with its Abstract sequelae of acute tubular necrosis and disseminated intravascular Introduction : Hemorrhage is the single most important cause of maternal death worldwide. coagulation, low birth weight babies, Obstetrical hemorrhage accounts for almost half of all postpartum deaths in developing increased incidence of Prematurity countries. Among them Abruptio placenta occurs in around 1% of all pregnancies. Aim of and still birth.9, 10.The purpose of this this study was to determine the maternal and fetal outcome in pregnancy complicated by study was to determine the risk abruption placenta in relation to the risk factors. factors,clinical presentation and Methods: This was a retrospective study conducted in the Department of Obstetrics and outcome of pregnancies diagnosed Gynecology, Mamata medical college, khammam from January 2010 to December 2014 for with abruptio placenta. The aim of this a period of five years. All pregnant women who were diagnosed with abruptio placenta after study was to determine the maternal 28 weeks of gestation were included in the study. Patients were identified from the admission and fetal outcome in pregnancy and labour room registers. complicated by abruption placenta in Results: Total number of deliveries during the study period were 4000. Patients identified with relation to the risk factors. abruptio placenta were 100, giving a frequency of 2.5%. Majority women were multigravidae METHODS and 56% of all the between 26-30 years of age. The mean gestational age at diagnosis was 34 ± 4.21 weeks. Vaginal bleeding was the most common clinical finding seen in 80% of the This was a retrospective study women, followed by blood stained amniotic fluid in 16% suggesting concealed abruption conducted in the department of placenta. Fetal heart sounds were absent on admission in 65% of the women. Most common Obstetrics and Gynaecology , Mamata cause of abruption 44% was either patients with past history of pre – eclampsia or PIH in the medical college, Khammam from present pregnancy. 9 patients with couvelaire uterus were identified and treated effectively. January 2010 to December 2014 for Among them, two patients died due to postpartum hemorrhage. Parity and gestational age a period of five years. All pregnant were found to be significant risk factors for abruptio placentae. women who were diagnosed with abruptio placenta after 28 weeks of Conclusion: Abruptio placenta was associated with poor maternal and fetal outcomes. gestation were included in the study. Early diagnosis and significant treatment of pre eclampsia during the antenatal period would Since ours is a referral centre many prevent abruption and related complications. patients were unbooked without Keywords: Abruption,couvelaire uterus,maternal and fetal outcome. proper antenatal care and are usually admitted with complications.
