Material and methods: we conducted a retrospective study which began on 1 January 2009 and was completed the June 30, 2009. All pregnancies which reached 41 Its and 1 day was included. A surveillance all the 48 hours with an attitude waiting up to 41 and 5 days was achieved with a trigger systematic beyond this term or in case of an anomaly during the monitoring.
Results: The analysis of the results has highlighted: no increase in complications kindergartens (cesarean, extraction instrumental), the perinatal morbidity (Macrosomia, Ph, hospitalization in neonatology, inhaled meconium) seemed slightly decreased as compared to the literature. The Sonography obtains a sensitivity of 21.2% with a positive predictive value of 87.5%.
Conclusion: At the end of this work, we observe that the protocol used is not producing an increase in maternal morbidity and perinatal. The Sonography should no longer be part of the monitoring of prolonged pregnancies
