Insights
Fetal splenic artery pulsatility index (PI) can predict neonatal intensive care unit (NICU) admission in gestational diabetes mellitus (GDM) class A1 pregnancies. A lower fetal splenic artery PI indicates a higher likelihood of NICU admission.
Area of Science:
- Perinatology
- Fetal Medicine
- Maternal-Fetal Medicine
Background:
- Fetal well-being assessment is crucial in pregnancies complicated by gestational diabetes mellitus (GDM).
- The fetal splenic artery pulsatility index (PI) is a Doppler ultrasound parameter reflecting fetal well-being.
- Predicting adverse outcomes in GDM class A1 pregnancies can optimize neonatal care.
Purpose of the Study:
- To evaluate the predictive value of fetal splenic artery pulsatility index (PI) for neonatal intensive care unit (NICU) admission in gestational diabetes mellitus (GDM) class A1.
- To determine if a low fetal splenic artery PI is a significant indicator for NICU admission in this population.
Main Methods:
- Prospective case-controlled study involving 60 singleton pregnancies with GDM class A1.
- Fetal splenic artery Doppler parameters (PSV, PI, RI, EDV) were measured.
- Neonatal intensive care unit (NICU) admission rates were recorded and analyzed.
Main Results:
- Fetal splenic artery PI was significantly lower in cases requiring NICU admission compared to controls (0.94 ± 0.29 vs. 1.70 ± 0.53, p < 0.001).
- A splenic PI cutoff of 1.105 cm³ demonstrated high sensitivity (97.9%) and specificity (58.3%) for predicting NICU need (AUC 0.968).
- Low fetal splenic artery PI was a significant predictor of NICU admission (p = 0.006).
Conclusions:
- Fetal splenic artery Doppler evaluation is a valuable tool for predicting NICU admission in neonates of mothers with GDM class A1.
- Obstetricians are encouraged to utilize this simple, rapid assessment to alert neonatologists about potential NICU requirements.
- This method aids in proactive management and resource allocation for high-risk neonates.
Abstract:
The fetal splenic artery pulsatility index is a parameter that reflects fetal well-being and has been used as a predictor of adverse pregnancy outcomes. The aim of this study was to investigate the predictive value of the splenic artery pulsatility index in gestational diabetes mellitus class A1 cases for intensive care unit admission. In this prospective case-controlled study, only sixty single pregnancy cases diagnosed with gestational diabetes mellitus class A1 were evaluated. Fetal splenic artery Doppler parameters such as peak systolic velocity, pulsatility index, resistivity index, and end-diastolic velocity were measured in all cases. The rate of requirements for the neonatal intensive care unit was noted. In cases requiring fetal intensive care, the fetal splenic pulsatility index was found to be statistically significantly lower than in healthy cases without it (0.94 ± 0.29 vs. 1.70 ± 0.53, respectively, p < 0.001, Student's t-test). When the fetal splenic PI cutoff value was selected as 1.105 cm3, the sensitivity was calculated as 97.9% and the specificity as 58.3% for predicting the need for fetal intensive care (AUC 0.968, p < 0.001, 95% CI 0.929-0.998). The use of a low fetal splenic artery PI parameter is a significant and good indicator for predicting the need for fetal intensive care according to the binary logistic regression analysis result (p = 0.006). This study suggests that evaluation of fetal splenic artery Doppler in mothers with gestational diabetes mellitus may be used to predict neonates requiring a newborn intensive care unit. Therefore, it is recommended that obstetricians use this simple, rapid, and valuable evaluation of fetal splenic artery Doppler and alert the neonatologist that a newborn intensive care unit may be required.
