ABSTRACT
Objective: This study aimed to investigate the predictive value of pulmonary pressure parameters detected by Doppler ultrasonography for respiratory distress syndrome (RDS). Material and Methods: This study was conducted between January 2017 and December 2018. Twenty five newborns who were born before 37th gestational week without anomalies and had no pregnancy complications were included in the study. All pregnants were examined with Doppler ultrasonography in the last 3 days before birth. Pulmonary artery acceleration time (AT) and pulmonary artery ejection time (ET) were evaluated. Newborns were evaluated for RDS and divided into two groups as positive and negative. SPSS 25.0 program was used for statistical analysis. p<0.05 values were considered statistically significant. Results: Six newborns were diagnosed with RDS and 19 were not. The difference between the mean age of the mothers of the RDS (+) and RDS (-) groups was significant (p<0.05). However, there was no significant relationship between the groups in terms of height, weight, body mass index, gravida, and parity (p>0.05). For AT, ET, and AT/ET, statistical differences were observed between the groups (p=0.003, p=0.012, p=0.001). Conclusion: It showed an inverse correlation between fetal AT/ET and premature neonatal RDS. Fetal AT/ET ratio measurement may be a useful and reliable non-invasive method for predicting RDS.
