  1. 1. INTRODUCTIONDeath from hemorrhage still remains a leadingcause of maternal mortality. Is one of theleading causes of ante partum hospitalization,maternal morbidity, and operative intervention.MEDICAL EMERGENCY !It is the per vagina blood loss after 20weeks’ gestation.

  17. 17. The most characteristic event in placenta previa is painless hemorrhage.(This usually occurs near the end of or after the second trimester)The initial bleeding is rarely so profuse as to prove fatal.It usually ceases spontaneously, only to recur. Placenta previa may be associated withplacenta accreta, placenta increta orpercreta. Coagulopathy is rare with placenta previa.  
  18. 18. Placenta previa or abruption should always be suspected in women with uterine bleeding duringthe latter half of pregnancy.The possibility of placenta previa should not be dismissed until appropriate evaluation, includingsonography, has clearly proved its absence. Thediagnosis of placenta previa can seldom beestablished firmly by clinical examination. Suchexamination of the cervix is never permissibleunless the woman is in an operating room withall the preparations for immediate cesareandelivery, because even the gentlest examinationof this sort can cause torrential hemorrhage.
  19. 19. The simplest and safest method of placental localization is provided by transabdominalsonography.Transvaginal ultrasonography has substantively improved diagnostic accuracy of placenta previa.MRI At 18 weeks, 5-10% of placentas are low lying. Most ‘migrate’ with development of thelower uterine segment.

  21. 21. Determine the amount and type of bleeding Inquire as to presence or absence of pain inassociation with the bleeding Recordmaternal and fetal VS Palpate for thepresence of uterine contractionsEvaluate laboratory data on HCT and HGB Assess fetal status with continuous fetalmonitoringNever perform a vaginal examination when pt is bleeding 
  22. 22. Altered Tissue Perfusion related to excessive bleeding causing fetal compromise Frequently monitor mother and fetusAdminister IV fluids as prescribed Position onside to promote placental perfusionAdminister oxygen as facemask as indicated(8-10 per minute) 

  25. 25. Placenta accreta Immediate hemorrhage, with possible shock and maternal deathIncreased risk for anemia secondary to increased blood lossinfection secondary to invasive procedures to resolve bleedingIntrauterine growth restriction (IUGR) Congenital anomalies Fetal mortality resulting from hypoxia in utero prematurity 

  27. 27. Defined as the premature separation of the normally implanted placenta.The Latin abruptio placentae, means "rending asunder of the placentaOccurs in 1-2% of all pregnancies Perinatal mortality rate associated with placental abruption was 119 per 1000 birthscompared with 8.2 per 1000 for all others.
  28. 28. premature separation of the implanted placenta before the birth of the fetusHemorrhage can be either occult(covert) or apparent(overt).With an occult hemorrhage, the placenta usually separates centrally, and a largeamount of blood is accumulated under theplacenta. When the apparent hemorrhage is present, the separation is along the placental margin,and blood flows under the membranes andthrough the cervix.
  29. 29. The primary cause of placental abruption is unknown, but there are several associatedconditionsIncreased age and parity Preeclampsia Chronic hypertension Preterm ruptured membranes Multifetal gestation Hydramnios Cigarette smoking  Thrombophilias Cocaine use Prior abruption Uterine leiomyoma External trauma 

Determine the amount and type of bleeding and the presence or absence of pain.Monitor maternal and fetal vital signs, especially maternal BP, pulse, FHR, and FHR variability.Palpate the abdomen Note the presence ofcontractions and relaxations between contractions(if contractions are present)If contractions are not present assess the abdomen for firmnessMeasure and record fundal height to evaluate the presence of concealed bleeding.
