“…In present study, most of the patients were in age group <30 yrs (91.10%) which was similar to the study conducted by Eik-Nes SH in which 80.6% patients were in age group <34 yrs. 3 This may be because mostly reproduction occur in this age group in our country.…”

“…The incidence of post term pregnancy depends on whether the calculation is based on the history or early pregnancy ultrasonography is also used to find the EDD. 3,4 A series of changes occur in the amniotic fluid, placenta and fetus which are associated with prolonged gestation. It has been reported that in a pregnancy which has crossed the EDD, there is an increased risk of intrapartum fetal distress mostly due to oligohydramnios, meconium stained liquor, macrosomia, fetal post maturity syndrome and cesarean delivery.…”

Background:The term delivery is defined as that occurring between 259 and 294 days of pregnancy from the last menstrual period. If the pregnancy exceeds this period, it is called as post term pregnancy. Our center is in rural area where most of the patients are unbooked or even booked patients are also loss of follow up. So, this study was done to know the incidence of prolonged pregnancy and maternal and fetal outcome in case of prolonged pregnancy in our rural population. Methods: This study was a retrospective observational study for 1 year, to analyze the maternal and fetal outcome of post term pregnancies. Data was collected from hospital record and analysed. Results: Out of 5210 total deliveries 1.49 % were beyond 42 wks. 57.69 % patients delivered vaginally whereas 42.3 % patients needed cesarean section. 6.41 % neonates developed meconium aspiration syndrome and 15.38 % of neonates needed NICU admission for different indications. Conclusions: This study concluded that prolonged pregnancy is associated with adverse outcomes like fetal distress, meconium aspiration syndrome and more neonatal ICU admissions. The outcome of prolonged pregnancy can be improved by proper counselling for follow up during pregnancy and proper monitoring and appropriate management during labour.

“…However, it seems clear that, for all except one study published between 1950 and 2007 (involving approx. 37 000 women), ultrasound exposure in vivo had no significant influence on mean birth weight [56][57][58][59][60][61][62][63][64][65][66][67]; only one study has given cause for concern [63]. In this Australian randomized controlled trial, half of the 2843 women studied were offered continuous wave Doppler ultrasound examinations five times in the third trimester.…”

Modern ultrasound imaging for diagnostic purposes has a wide range of applications. It is used in obstetrics to monitor the progress of pregnancy, in oncology to visualize tumours and their response to treatment, and, in cardiology, contrast-enhanced studies are used to investigate heart function and physiology. An increasing use of diagnostic ultrasound is to provide the first photograph for baby's album-in the form of a souvenir or keepsake scan that might be taken as part of a routine investigation, or during a visit to an independent high-street 'boutique'. It is therefore important to ensure that any benefit accrued from these applications outweighs any accompanying risk, and to evaluate the existing ultrasound bio-effect and epidemiology literature with this in mind. This review considers the existing laboratory and epidemiological evidence about the safety of diagnostic ultrasound and puts it in the context of current clinical usage.

“…Fetal examination using ultrasound technology is a safe and evidence-based procedure in pregnancy care in high income countries [1] [2] [3]. The ultrasound examinations are performed by formally trained operators during pregnancy to calculate gestational age (GA), estimate date of delivery (EDD) and track fetal growth [4] [5].…”

An automatic method for measuring the fetal mean abdominal diameter (MAD) or abdominal circumference (AC) with ultrasound is proposed. From a correctly presented abdominal section suitable for MAD or AC measurement, the location of fetal abdomen is detected by image processing. Thereafter, an active contour model is converged along the abdominal boundary for measurement purposes. The validation data set contained 310 images of fetuses with gestational age (GA) from 14 to 41 weeks. The measurement success rate was 88.1%. By manually indicating the location of the abdomen, the success rate was further improved to 95.8% for the failed cases. The correlation between manual and automatic measurements was 0.95 and the intraclass correlation coefficient (ICC) was 0.976 (95% confidence interval (CI); 0.969 -0.981). The average method execution time was 0.3 s. The mean error was lower in young fetuses (0.4%) than in older fetuses (−2.1%). The proposed cross-platform method was implemented on a portable, low-cost ultrasound machine prototype targeted for low-and middle-income countries (LMIC); the results achieved were comparable to those of other state-of-the-art automatic methods.
