Background: Preterm premature rupture of membranes (PPROM) impact on approximately 3 percentage of pregnancies and is linked with severe maternal problems, resulting in, significant neonatal mortality and morbidity. The pulmonary artery acceleration to ejection period (PATET) ratio has been revealed
Aim of the work: to predict respiratory complications in late preterm neonates between the various ultrasound factors tested to predict neonatal respiratory complications (NRCs). Methods: This study was a prospective study performed at Bab El Sheria Al-Azhar University Hospital among 385 pregnant women undergoing prenatal treatment in the Department of Gynecology and Obstetrics. We noticed 36 patients with NRC deemed to be a case group and took 36 patients without NRC as a control group. PATET has been performed. Baseline features and functional perinatal outcomes were taken from the medical records after delivery. Results: In patients with NRC, the delivery mode was statistically significantly more significant than in patients without NRC. There was a statistically significant decrease in birth weight and gestational age, Apgar scores at 1 and 5-minutes among NRC patients relative to non-NRC patients. In addition, there was a statistically significant reduction of pulmonary artery acceleration in patients with NRC during ejection duration relative to patients without NRC. Statistically significant positive associations were observed between the pulmonary artery's acceleration to the ejection period and gestational age.
Conclusion: The assessment of PATET offers a non-invasive way of assessing neonatal respiratory complications in the preterm prelabor of membranes with reasonably appropriate degrees of specificity, sensitivity, accuracy, and predictive values.
