Abstract
|
|
|
The fetal-pelvic index is a recently described means of identifying the presence of absence of cephalo-pelvic disproportion. In this follow up study, the efficacy of the fetal-pelvic index evaluated in 98 term pregnant women at high risk for
cephalo-pelvic disproportion and was compared with two other methods used to identify cephalo-pelvic disproportion (Colcher-Sussman X-ray pelvimetry and ultrasound-derived estimated fetal weight≥4000gm). After adequate labor trials, 45 of 52
patients
who required operative intervention had a positive fetal-pelvic index (senstivity=87%). All of the 7 patients with a false-negative fetal-pelvic index value had persistent malpositions (6 occipito-posterior, 1 occipito-transverse position).
Spontaneous
vaginal deliveries occurred in 46 patients with 41 of them having a negative fetal-pelvic index(specificity-89%). The overall predictability of the fetal-pelvic index in this patient population was 88% and positive predictability was 90%. In
contrast,
when used alone, neither X-ray pelvimetry nor ultrasound-derived estimated fetal weight≥4000gm provided accurate identification of fetal-pelvic disproportion.
