Assessment of Umbilical Cord pH and APGAR Scores in Neonates Delivered by Cesarean Section Due to Fetal Distress. مجله کاسپین کودکان. 1400; 7 (2) :552-559
چکیده: (4087 مشاهده)
Background and Objective: The APGAR score is commonly used to assess neonates for fetal distress and asphyxia, but a low score doesn’t always mean fetal asphyxia has occurred. The non-stress test (NST) is another method used to monitor fetal health and decide when to end a pregnancy in emergencies, though it can sometimes inaccurately suggest hypoxia, leading to unnecessary cesarean sections. The aim of this study was to evaluate the umbilical cord PH and APGAR scores of neonates delivered by cesarean section due to fetal distress indicated by the NST.
Methods: In this analytical cross-sectional study, all 139 neonates with an impaired NST were enrolled in 2018. In addition to information such as 1st and 5th minute APGAR scores and umbilical cord pH, the demographic data of mothers and neonates were gathered.
Findings: In total, 252 impaired NST patterns were found in all studied neonates. Bradycardia and late decelerations had a significant relationship with acidosis. Moreover, late decelerations were associated with lower APGAR scores. Umbilical artery pH was significantly correlated with 1st-minute (r=0.34; P=0.001) and 5th-minute APGAR scores (r=0.32; P=0.001). Positive predictive value of NST was 48.9%.
Conclusion: The results showed that NST had a moderate positive predictive value for the diagnosis of fetal acidosis in neonates with tachycardia or non-reactive NST. There was a significant relationship between late deceleration and arterial acidosis with first and fifth minutes APGAR score in neonates. The mean total arterial acidosis rate was significantly lower in the group with APGAR score less than 7.
