Outcome Measures

Primary Outcomes (1)

  • Acceleration time to ejection time (At/Et) ratio of fetal pulmonary artery Doppler in neonates with good and poor outcome.

    (At/Et) ratio will be measured in the fetal main pulmonary artery Doppler and will be correlated with the neonatal outcome

    Baseline

Secondary Outcomes (11)

  • The pulsatility index (PI) of the fetal pulmonary artery Doppler in neonates with good and poor outcome.

    Baseline

  • The resistance index (RI) of the fetal pulmonary artery Doppler in neonates with good and poor outcome

    Baseline

  • The systolic to diastolic ratio (S/D) of the fetal pulmonary artery Doppler in neonates with good and poor outcome

    Baseline

  • The peak systolic velocity (PSV) of the fetal pulmonary artery Doppler in neonates with good and poor outcome

    Baseline

  • Optimal timing of delivery in PAS for best neonatal outcome

    baseline

  • +6 more secondary outcomes

Interventions

A full obstetric ultrasound scan will be performed to assess signs of placental invasion, to document fetal biometry, estimated fetal weight, amniotic fluid index, assess fetal lung maturity parameters as pulmonary artery Doppler waveforms, amniotic fluid free floating particles, bowel echogenicity, fetal epiphyseal ossific centers, liver/lung echogenicity and kidney length. Pulmonary artery Doppler: Fetal echocardiography will be done. Pulmonary artery Doppler flow waveforms, including pulsatility index, resistance index, systolic-to-diastolic ratio, peak systolic velocity, and acceleration time to ejection time ratio will be measured in the main pulmonary artery.

Eligibility Criteria

Age18 Years - 42 Years
Sexfemale
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

Women with placenta accreta spectrum with singleton pregnancy undergoing cesarean delivery in Kasr Alainy hospital.

You may qualify if:

  • Age: 18-42 years old
  • Patients who will be diagnosed with placenta accreta spectrum preoperatively according to (ACOG 2018), (Jauniaux et al., 2018 a), (Jauniaux et al., 2018 b)
  • Those who will undergo elective or emergency cesarean.
  • With gestational age: 34 0/7 - 38 6/7 weeks
  • Under the effect of general anesthesia

You may not qualify if:

  • Multifetal pregnancy
  • Intrauterine fetal death
  • Intrauterine growth restriction (IUGR) which is defined as a rate of fetal growth that is less than normal for the growth potential of that specific infant
  • Diabetes with pregnancy either gestational or overt which is defined as any degree of glucose intolerance with an onset or first recognition during pregnancy
  • Pregnancy induced hypertension defined as either systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥ 90 mmHg. It is classified as one of four conditions: preexisting hypertension, gestational hypertension, preeclampsia, preexisting hypertension with superimposed preeclampsia
  • Premature rupture of membranes
  • BMI above 40 due to technical difficulties to obtain accurate measures
  • Narcotic usage during anesthesia before fetal delivery
  • Major congenital fetal anomalies whether diagnosed before or after delivery
  • Maternal fever more than 37.4 degree
  • Emergent cases presenting with fetal distress (bradycardia will be defined as fetal heart rate \< 110 beat per minute)
  • Patients who have not completed the course of antenatal corticosteroids according to (RCOG 2010).
  • Intraoperative spontaneous separation of the placenta
