Abstract
Posttenn pregnancy is associated with increased perinatal mortality and morbidity.
Controversy exists about the appropriate method of fetal surveillance in postern pregnancy
The aim of this study was to investigate the predictive value of vibroacoustic stimulation with AFI versus fetal biophysical profile with modified score of Manning et aL (1997) in evaluation of perinatal outcome in 60 postterm pregnancy women who have no medical or obstetrical problem and have a reliable gestational age of 41 week or more at initial evaluation.
Gestation was estimated on the basis of certain last menstrual period with history of regular cycle. Each woman selected has been subjected to detailed history, general, abdominal, vaginal examination and ultrasonographic evaluation
The cases were randomly allocated into one of two groups each comprising 30 cases. Fetal well being was monitored by either vibroacoustic stimulation and amniotic fluid index (VAS/AFI) or fetal biophysical profile (FBP) with modified score of Manning et aL (1987).
Both groups were compared regarding normal and abnormal monitoring, labor, delivery characteristics, and outcome measures.

SUMIL1R Y AND cuv ’Ma\
Our results showed that there were more significantly abnormal antenatal monitoring results in FBP group than VAS/AFI, as a result there were more obstetric inter\ cation for abnormal fetal monitoring in the FBP group. Howe \ er there were no statistically significant differences in outcomes related to labor, delivery or neonatal outcome between both groups.
These results suggest that 1:13P does not improve perinatal outcome, but it is more likely to be abnormal than combination of VAS/AFI. The negative predictive value oh both FBP and VAS/AFI were nearly similar 03.8 and 92.3%, respectively) while the positive predictive value of VAS/AFI was higher (50%) compared to that of FBP (28.6%). These indicated that the VAS/AFI is an excellent practical screening test. It is simple, rapid, inexpensive means for antepartum fetal surveillance and good predictor of fetal well-bing. In addition it reduces the technical skill need for detailed fetal biophysical profile.

SUMMARY AND CONCLUSION
CONCLUSION:
•VAS/AFI is a simple and rapid test for assessment of fetal well-being in posterm pregnancy that suits busy outpatient clinic.
•The specificity, positive predictive value and overall accuracy of VAS/AFI in predicting abnormal neonatal outcome is higher than that of the FBP.
•FBP is associated with higher incidence of false abnormal results and subsequent induction of labor. These abnormal results are attributable of FBP score, 6, a poor predictor of perinatal outcome.
•Both VAS/AFI and FBP are equally comparable regarding outcomes related to labor and delivery, however VAS/AFI test is a better predictor of the development of intrapartum fetal distress.
•The preliminary results of the present study suggests the utility of VAS/AFI as a tool of assessment of fetal well-being in postterm pregnancy. However, further studies on a larger sample size are required to verify the usefulness of the procedure.
