  13. MEDICATIONS:

  14. dexamethasone Ferrous

  15. INVESTIGATIONS:

  16. INVESTIGATIONS: • Ultrasonographic Result PU 31weeks + 5days AOG by fetal biometry Live Singleton in cephalic presentation, Male fetus Good Cardiac and somatic activity Left Lateral Placenta, Grade II, PreviaTotalis Adequate fluid volume BPP= 8/8

  17. Actual Ultrasound Result bladder Uterus

  18. INVESTIGATIONS: • MRI Result: Pelvis shows gravid uterus with singlefetus and the placenta is in left lateral position and in lower uterine segment completely covering the internal os and shows heterogenoussigal intensity with bulging of lower uterine segment and irregular thick intraplacental T2 dark bands and loss of thin subplacentalmyometrial zone and tenting of the urinary bladder seen along its ntero-superior margin, most probably suggestive of placenta previa.

  19. PATHOPHYSIOLOGY

  20. TOPIC PRESENTATION INTRODUCTION: The term placenta previa refers to a placenta that overlies or is proximate to the internal os of the cervix. The placenta normally implants in the upper uterine segment. In placenta previa, the placenta either totally or partially lies within the lower uterine segment. Traditionally, placenta previa has been categorized into 4 types: • Complete placenta previa, where the placenta completely covers the internal os. • Partial placenta previa, where the placenta partially covers the internal os. Thus, this scenario happens only when the internal os is dilated to some degree. • Marginal placenta previa, which just reaches the internal os, but does not cover it. • Low lying placenta, which extends into the lower uterine segment but does not reach the internal os.

  25. ANATOMY AND PHYSIOLOGY

  26. ETIOLOGY • Increased maternal age • Uterine factors: • Previous CS • Instrumentation of the uterine cavity (D and C for miscarriages or Induced Abortions) • Placental factors: • Multiparity • Cigarette smoking • Living at high altitude

  27. SIGNS AND SYMPTOMS • Vaginal bleeding • Painless but can be associated with uterine contractions and abdominal pain • Bleeding may range from light to severe • Gross hematuria

  28. INTERVENTION • Bed rest in lateral position to maximize venous return and placental perfusion • Women in the third trimester are advised to avoid sexual intercourse and exercise and to reduce their activity level

  29. TREATMENT Depends upon the extent and severity of bleeding, the gestational age and condition of the fetus, position of the placenta and fetus and whether the bleeding has stopped. • Caesarean section – as soon as he baby can be safely delivered (typically after 36weeks gestation). Although emergency CS at any earlier gestational age may be necessary for heavy bleeding that cannot be stopped. • Hysterectomy

  30. Conservative Management, bed rest

  31. Continuous maternal and fetal monitoring

  32. Blood transfusion and IVF for heavy bleeding • CBC, blood typing and cross matching of at least 4 units of blood

  33. Tocolytics (Nifedipine 10mg TID) • Corticosteroids (Dexamethasone 6mg IM q6 for 24hours)

  34. COMPLICATIONS Maternal: • Increased risk of PROM leading to premature labor • Immediate hemorrhage with possible shock and maternal death • Postpartum hemorrhage • Placenta Accreta • Accreta Vera – a term used to denote a placenta with villi that adhere to the superficial myometrium • Increta – when the villi adheres to the body of the myometrium, but not through its full thickness • Percreta – when the villi penetrate the full thickness of the myometrium and may invade neighboring organs such as the bladder or the rectum

  35. Fetal: Abnormal fetal presentation (breech) Reduced fetal growth Prematurity

  36. PRIORITIZATION OF NURSING PROBLEMS • Impaired fetal gas exchange related to altered blood flow and decreased surface area of gas exchange at site of placental detachment • Ineffective Tissue Perfusion related to excessive bleeding causing fetal compromise • Deficient Fluid Volume related to excessive bleeding • Anxiety related to excessive bleeding, procedures, and possible fetal-maternal complications

  37. NCP: IMPAIRED FETAL GAS EXCHANGE

  38. NCP: DEFICIENT FLUID VOLUME

  39. CONCLUSION Placenta previa is a medical emergency that needs immediate management because it can lead to serious maternal and fetal complications, even death of one or both of them. Once diagnosed, close observation must be done to monitor the status of both the mother and the baby. Any untoward symptom must be urgently referred to the attending physician. Complications can be diminished if the diagnosis and management are done at an early stage.
