Abstract
OBJECTIVES: The present study was conducted to compare the gravidogram and ultrasound in the detection of intrauterine growth restriction. METHODS: This study was conducted in the Department of Obstetrics and Gynecology, Voluntary Health Services, Chennai (TN) from August 2007-May 2009. The study included 321 women with singleton pregnancy in a longitudinal lie. These women underwent serial symphysio-fundal height measurements and ultrasound. Birth weights of the newborns were noted at the time of delivery. Gravidogram and ultrasound findings were correlated with the birth weights. RESULTS: The sensitivity of the ultrasound in the detection of IUGR was higher (85.2 vs 74.1 %) than the gravidogram, but the specificity was almost the same (96.6 and 95.9 %). CONCLUSIONS: The gravidogram is a simple and inexpensive screening tool and as useful as an ultrasound in detection of intrauterine growth restriction. Both gravidogram and ultrasound, when used together, have higher detection rates.
