We sought to confirm whether changes in fetal MCA Doppler PI due to position changes are associated with adverse outcomes.We conducted a prospective cohort study of pregnant people with a singleton, nonanomalous fetus, recruited between 18 and 24 weeks of gestation, in a single tertiary care center from December 2021 to February 2022. MCA Dopplers were obtained, and PI indices were measured and recorded, first in the supine position and then in the maternal left lateral (LL) position. The primary outcome was a composite of adverse outcomes (preeclampsia, fetal growth restriction, and oligohydramnios). Based on our prior findings suggesting that a PI Δ of 0.22 may serve as a dividing threshold between low- high-risk pregnancies, we divided the cohort into those above and below Δ = 0.22. Demographics were compared using univariable analyses. Multivariable logistic regression was performed comparing the composite and individual pregnancy outcomes controlling for statistically significant variables.We recruited 228 patients and followed them to delivery. There were 107 that had a PI Δ < 0.22 and 121 that had a PI Δ ≥0.22. The primary outcome of composite adverse outcomes did not differ between the groups (adjusted odd ratio [aOR]: 0.53; 95% confidence interval [CI]: 0.26-1.08). However, pregnancies with PI Δ ≥0.22 were more likely to develop preeclampsia than pregnancies with PI Δ < 0.22 (aOR: 3.30; 95% CI: 1.02-10.69).The primary outcome of composite adverse outcomes did not differ between the groups. However, we did find that a second trimester fetal MCA PI Δ ≥0.22 with maternal position changes at anatomy ultrasound was associated with developing preeclampsia.

Studies were compiled that assessed the accuracy of the GAP method in pregnant women at term (≥37 weeks gestation) with an ultrasound performed at 34 to 36 weeks gestation. Quality was assessed using the Newcastle-Ottawa scale, and risk of bias was assessed using the risk of bias in nonrandomized studies of interventions (ROBINS-I) tool.
