Abstract
Background: Fetal health diagnostic tests are tools to reduce the incidence of adverse outcomes and neonatal death. However, their diagnostic value is still debated in relation to various outcomes. The aim of this study was to evaluate the value of biophysical profile and sonographic cerebroplacental ratio in predicting childbirth mode and adverse neonatal outcomes.
Methods: In this cross-sectional study, 70 pregnant women (37-41 weeks) who were candidates for termination of pregnancy who were referred to Ayatollah Mousavi Hospital in Zanjan from October 2020 to May 2021 were studied. After selecting the mothers based on inclusion criteria, biophysical profile test (BPP) and CPR sonographic index were performed. Then delivery method, infant weight, fifth minute Apgar score, need for resuscitation and hospitalization of infants in NICU were recorded in each case. T-test, Mann-Whitney test and ROC curve in SPSS 22 software were used for statistical analysis. (P≤0.05).
Results: In this study, the mean (SD) gestational age of participants was 38.56±1.11 weeks. Based on the data, there was a statistically significant relationship between CPR and the infant's need for resuscitation and hospitalization in the NICU (P=0.021) and Apgar score (P=0.042). However, there was no statistically significant relationship between CPR and delivery method, gestational age and birth weight. BPP score was not significantly associated with any of the consequences. Based on the results of the ROC curve, CPR with a cut point of 1.59 with a sensitivity of 88.9% and a specificity of 75% is able to predict the need for resuscitation and hospitalization in the NICU, and with a sensitivity of 83% and a specificity of 54.5%, it is able to predict a low Apgar score. However, BPP score did not have a predictive role in any of the studied parameters.
Conclusion: It seems that CPR examination around delivery can be useful in predicting the condition of the baby immediately after birth and preparing the treatment staff for immediate action.
