Abstract

Introduction: Apgar scoring system, including conventional, expanded and combined Apgar scores have been used to evaluate the condition of the newborn in the first minutes of birth. Umbilical cord arterial blood gas analysis (UCABGA), is another method. We compared combined Apgar score with UCABGA in predicting short-term outcomes in neonates.

Method: A prospective cohort study conducted on 363 alive births. Neonates with major congenital anomalies, congenital cyanotic heart disease, congenital metabolic disorders and who transferred to other hospital excluded. Admission, discharge and demographic data and Apgar scores were recorded in a pre-designed form . After delivery, the umbilical cord was double clamped and an arterial blood sample was taken from the clamped part. Statistical analyses were done using SPSS version 22 statistical software and receiver operating characteristic (ROC) curve were used to analyze the correlations between variables.

Result: out of 350 Neonates (204 male and 146 female) with mean gestational age 33.37±4.12 weeks, 263 (75.1%) neonates were admitted and 34 neonates (9.7%) died. Retinopathy of prematurity(ROP) and Intraventricular hemorrhage (IVH) were recognized in 42 (12%) and 54 (15.4%) neonates respectively and 37 ( 10.6%) neonates ventilated mechanically. ROC curves shown higher sensitivity and Specificity of 5th minute Combined Apgar score than , PH and base deficit, in predicting short term outcomes except IVH.

Conclusion: Combined Apgar score at minute 5 is a better predictor than UCABGA in predicting Death, need to admission , retinopathy of prematurity and need to mechanical ventilation and None are good predictors for IVH.
