Placenta previa is a condition of pregnancy in which the placenta is implanted abnormally in the lower part of the uterus. It is the most common cause of painless bleeding in the third trimester of pregnancy. It occurs in four degrees: low-lying placenta, which is implantation in the lower rather than in the upper portion of the uterus; marginal implantation, in which the placenta edge approaches that of the cervical os; partial placenta previa, which is implantation that occludes a portion of the cervical os; and total placenta previa, in which the implantation totally obstructs the cervical os. Increased parity, advanced maternal age, past cesarean births, past uterine curettage, multiple gestations, and perhaps a male fetus are all associated with placenta previa. "Painless vaginal bleeding, usually bright red, is the main characteristic of placenta previa."Painless vaginal bleeding, usually bright red, is the main characteristic of placenta previa. The bleeding in placenta previa doesn’t usually begin, however, until the lower uterine segment starts to differentiate from the upper segment late in pregnancy (week 30) and the cervix begins to dilate. At this point, because the placenta is unable to stretch to accommodate the different shapes of the lower uterine segment or the cervix, a small portion loosens, and damaged blood vessels begin to bleed. Nursing Care PlansNursing care management and treatment of placenta previa is designed to assess, control, and restore blood loss and to deliver a viable infant. Immediate therapy includes starting an IV line using a large bore catheter. Here are four (4) placenta previa nursing care plans and nursing diagnoses:
The bleeding of placenta previa, like that of ectopic pregnancy, creates an emergency situation as the open vessels of the uterine decidua place the client at risk for hemorrhage. Postpartum hemorrhage may occur because the lower uterine segment, where the placenta was attached, has fewer muscle fibers than the upper uterus. The resulting weak contraction of the lower uterus does not compress the open blood vessels at the placental site as effectively as would the upper segment of the uterus. Nursing Diagnosis

Desired Outcomes
Nursing Assessment and Rationales1. Assess color, odor, consistency, and amount of vaginal bleeding. 2. Monitor the client’s vital signs. 3. Assess hourly intake and output. 4. Assess abdomen for tenderness or rigidity- if present, measure abdomen at the umbilicus (specify time interval). 5. Monitor the fetal heart rate and uterine contractions continuously. Nursing Interventions and Rationales1. Weigh perineal pads to estimate blood loss. 2. Avoid vaginal examinations. 3. Position the client supine with hips elevated if ordered or in a left side-lying position. 4. Review ultrasound and laboratory results. 5. Perform an Apt or Kleihauer-Betke test. 6. Provide supplemental O2 as ordered via face mask or nasal cannula @ 10-12 L/min. 7. Initiate IV fluids as ordered (specify fluid type and rate). 8. Administer tocolytic agents as prescribed. 9. Administer blood and blood products as indicated. 10. Prepare for a vaginal or cesarean birth. Recommended ResourcesRecommended nursing diagnosis and nursing care plan books and resources.
