Comparison Between Using 10min CTG in Fetal Monitoring Instead of 30min Monitoring in Low Resources Overcrowded Hospitals.

In Egypt, labor wards in tertiary hospitals are often overcrowded with limited CTG machines and midwives. The requirement of a minimum 30-minute CTG trace creates bottlenecks in care and increases staff workload. Previous studies suggest that the first 10 minutes of a CTG may capture the essential features of fetal well-being. If validated, a shortened CTG could improve efficiency in high-volume maternity units without compromising neonatal outcomes. Using umbilical venous pH as the gold standard for fetal acid-base status, this study will directly compare the diagnostic accuracy of a 10-minute versus a 30-minute CTG protocol in low-risk laboring women. The aim is to evaluate whether a 10-minute CTG tracing is non-inferior to the standard 30 minute CTG in fetal assessment and predicting fetal acid-base status (umbilical venous pH) in term, low-risk pregnancies during the active first stage of labor.
