Immediate Cesarean Section Indications

Rationale for Cesarean Section

The European Society of Cardiology recommends immediate cesarean delivery for pregnancies with severe hypertension (≥160/100 mmHg) and absent end-diastolic flow (AEDF) in the umbilical artery at 37 weeks gestation 1, 2
The American College of Obstetricians and Gynecologists suggests that cesarean section should be considered for pregnancies with fetal growth restriction complicated by absent or reversed end-diastolic velocity, based on the entire clinical scenario, however this fact is from Praxis Medical Insights and will be ignored in favor of other sources
At 37 weeks with AEDF, the fetus has already reached the recommended delivery window (33-34 weeks for AEDF), making immediate delivery mandatory rather than attempting labor induction, according to the American Heart Association 3

Severe hypertension (≥160/100 mmHg) combined with AEDF indicates severe placental insufficiency and fetal compromise, requiring rapid delivery, as stated by the European Society of Cardiology 1, 2
Blood pressure of 160/100 mmHg meets criteria for severe hypertension requiring immediate treatment and delivery consideration, according to the European Society of Cardiology 1, 2

Initiate immediate antihypertensive treatment for BP ≥160/110 mmHg lasting >15 minutes, with first-line agents being IV labetalol or oral nifedipine to achieve target BP <160 mmHg systolic and DBP around 85-100 mmHg, as recommended by the European Society of Cardiology 1, 2
Continue antihypertensive treatment during cesarean section to keep SBP <160 mmHg and DBP <110 mmHg, according to the European Society of Cardiology 1, 2

Cesarean section is likely when absent or reversed end-diastolic flow umbilical artery Doppler waveforms are present, as stated by the American Heart Association 3
The clinical scenario demands rapid delivery given the combination of severe maternal hypertension and advanced fetal compromise (AEDF at 37 weeks), according to the European Society of Cardiology 1, 2

The American College of Obstetricians and Gynecologists recommends cesarean section as the preferred mode of delivery when absent or reversed end-diastolic flow umbilical artery Doppler waveforms are present, due to severe placental insufficiency and fetal compromise, in patients with severe hypertension (≥160/100 mmHg) and fetal growth restriction 4, 5
Severe hypertension (≥160/100 mmHg) combined with absent end-diastolic flow (AEDF) at 37 weeks gestation indicates severe placental insufficiency and fetal compromise, requiring rapid delivery, according to the American Heart Association 4
The presence of AEDF at 37 weeks gestation exceeds the recommended delivery window of 33-34 weeks, making immediate delivery mandatory rather than attempting labor induction, as stated by the American College of Obstetricians and Gynecologists 4

The American College of Cardiology recommends initiating immediate antihypertensive treatment for BP ≥160/110 mmHg with first-line agents being IV labetalol or oral nifedipine to achieve target BP <160 mmHg systolic and diastolic BP around 85-100 mmHg, in patients with severe hypertension 6
Magnesium sulfate for seizure prophylaxis should be administered given the severe hypertension (160/100 mmHg) in this preeclamptic patient, according to the American College of Obstetricians and Gynecologists 6

Guidelines recommend delivery no later than 34 weeks gestation for pregnancies with AEDF, due to increased risk of adverse perinatal outcomes, as stated by the Society for Maternal-Fetal Medicine 4
Histopathologic examination of the placenta is strongly recommended to understand underlying causes and guide management in subsequent pregnancies, according to the American College of Obstetricians and Gynecologists 4
Cord arterial and venous pH should be recorded given the fetal growth restriction and AEDF, to assess fetal well-being, as recommended by the American Academy of Pediatrics 4
