Your twins' arms, legs and bodies continue to fill out and are finally in proportion to their heads. Your twins' organs are continuing to mature and they are passing large amounts of water through their bladders, which is good practice for weeing once they're born.
Your twins should already be getting ready for birth by turning upside-down, with their heads pointing downwards. Your twins' skulls are still quite pliable and not completely joined, in part so they can ease out of the relatively narrow birth canal.

Identification of IUGR is crucial because proper evaluation and management can result in a favorable outcome. The latter includes fetuses that are small but have reached their appropriate growth potential. The lower the birth weight and the earlier the gestational age, the less the child's chance of catching up. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. With the advent of sophisticated antenatal assessment tools and new therapeutic modalities, many of these problems will probably become manageable in the future. These figures indicate that ultrasound, like other tests used to assess biologic function, is more specific in predicting the unaffected fetus than it is sensitive in the diagnosis of IUGR (Fig. Technique of Measuring the Amniotic Fluid Index (AFI) From: Dildy FA, Lira N, Moise Jr KJ, Riddle GD, Deter RD.

Certain pregnancies are at high risk for growth restriction, although a substantial percentage of cases occur in the general obstetric population.
Many babies are simply genetically small and are otherwise normal.1 Some women have a tendency to have constitutionally small babies.

Asymmetric growth restriction implies a fetus who is undernourished and is directing most of its energy to maintaining growth of vital organs, such as the brain and heart, at the expense of the liver, muscle and fat. This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. Although both parents' genes affect childhood growth and final adult size, maternal genes mainly influence birth weight.3,4A  Parity, age and socioeconomic status are intercorrelated and may also influence the pregnancy and the infant's birth weight. This type of growth restriction is usually the result of placental insufficiency.A fetus with asymmetric IUGR has a normal head dimension but a small abdominal circumference (due to decreased liver size), scrawny limbs (because of decreased muscle mass) and thinned skin (because of decreased fat). Ultrasound biometry is the gold standard for assessment of fetal size and the amount of amniotic fluid. The usual qualifier for reliable dating and establishment of an accurate gestational age is a certain date for the last menstrual period in a woman with regular cycles or assessment of gestational age by an ultrasound examination performed no later than the 20th gestational week, when the margin of error is seven to 10 days.
If the insult causing asymmetric growth restriction is sustained long enough or is severe enough, the fetus may lose the ability to compensate and will become symmetrically growth-restricted.
Therefore, identification of a constitutionally small infant is usually made in retrospect, after the infant is born. Early ultrasound examination, ideally at eight to 13 weeks of gestation, is more accurate for estimating gestational age than ultrasound assessment later in pregnancy. He received a medical degree and a doctoral degree from the University of Utah School of Medicine, Salt Lake City. Although ultrasound assessment is used later in pregnancy to estimate fetal weight, ultrasound dating is only accurate to about three weeks when it is performed at term. Daily blood pressure measurements, fetal movement profiles and biweekly nonstress tests remain normal for the next two weeks.
Serial ultrasonograms are important for monitoring growth restriction, and management must be individualized.
An error that is commonly made is to change a patient's due date on the basis of a third-trimester ultrasonogram. Estimated fetal weight is 1,465 g (3 lb, 4 oz), which places the infant in the 3rd percentile. At 34 weeks of pregnancy, the patient develops signs and symptoms of severe preeclampsia, and the decision is made to induce labor.
In the latter condition cephalic size is relatively spared in comparison to body weight, suggesting that the pathophysiologic process is both recent in onset and potentially remediable.13, 14The physician involved in antenatal recognition of IUGR should be well versed with current problematic and controversial issues in making such diagnoses. General management measures include treatment of maternal disease, good nutrition and institution of bed rest. The patient delivers a male infant weighing 1,680 g (3 lb, 11 oz), who does well in the intermediate care nursery.The management of IUGR must be individualized for each patient. Preterm delivery is indicated if the fetus shows evidence of abnormal function on biophysical profile testing. Techniques such as serial measurements of the uterine fundus are helpful in documenting continued growth if the measurements are performed by the same person. In addition to managing any maternal illness, a detailed sonogram should be performed to search for fetal anomalies, and karyotyping should be considered to rule out aneuploidy.16 Symmetric restriction may be due to a fetal chromosomal disorder or infection. Second, a description and critique of the sonographic methodology used in the assessment of fetal growth, BW, and oligohydramnios follows.
The fetus should be monitored continuously during labor to minimize fetal hypoxia.Fetal growth is dependent on genetic, placental and maternal factors. A tape measure should be used to measure the distance from the top of the pubic symphysis to the dome of the uterine fundus. This possibility should be discussed with the patient, who may decide to undergo a diagnostic procedure such as amniocentesis.
The fetus is thought to have an inherent growth potential that, under normal circumstances, yields a healthy newborn of appropriate size. This measurement, in centimeters, is normally within three weeks of the gestational age between 20 and 38 weeks of gestation. It should be remembered, however, that many infants with evidence of growth restriction are constitutionally small.
The maternal-placental-fetal units act in harmony to provide the needs of the fetus while supporting the physiologic changes of the mother.
A fundal height that lags by more than 3 cm or is increasing in disparity with the gestational age may signal IUGR. Serial ultrasound examinations are important to determine the severity and progression of IUGR.A controversy involves the timing of delivery to prevent intrauterine demise because of chronic oxygen deprivation. Limitation of growth potential in the fetus is analogous to failure to thrive in the infant. Preterm delivery is indicated if the growth-restricted fetus demonstrates abnormal fetal function tests, and it is often advisable in the absence of demonstrable fetal growth.
Intrauterine growth retardation: diagnosis, prognostication, and management based on ultrasound methods. Chicago, Year Book Medical Publishers, 1979) Careful attention to neonatal weight versus length (ponderal index) on a universal basis will remedy this situation. A history of a previous small-for-gestational-age infant has been reported to be among the most predictive factors for subsequent IUGR. The risks of prematurity must be weighed against the complications unique to IUGR.4General management measures include treatment of maternal disease, cessation of substance abuse, good nutrition and institution of bed rest. These women have up to a two- to fourfold increased risk of another similarly affected fetus.9,10Ultrasound BiometryUltrasound biometry of the fetus is now the gold standard for assessing fetal growth (Figure 2). The measurements most commonly used are the biparietal diameter, head circumference, abdominal circumference and femur length.

Percentiles have been established for each of these parameters, and fetal weight can be calculated. Options include the nonstress test, the biophysical profile and an oxytocin (Pitocin) challenge test. The biophysical profile involves assessment of fetal well-being with a combination of the nonstress test and four ultrasonographic parameters (amniotic fluid volume, respiratory movements, body movements and muscle tone). This finding implies that if the BPD growth bracket is defined, for instance by 30 weeks' gestation, fetal cephalic growth potential can be estimated for the remainder of pregnancy.
In the absence of reliable dating, serial scans at two-or three-week intervals must be performed to identify IUGR. The use of Doppler flow velocimetry, usually of the umbilical artery, identifies the growth-restricted fetus at greatest risk for neonatal morbidity and mortality.
In controlled trials, Doppler analysis has been associated with improved outcome,1 although it is considered experimental by the American College of Obstetricians and Gynecologists. Am J Obstet Gynecol 126: 485, 1976) The concept of comparing actual to potential cephalic growth is similar to that proposed by Turner,30 who underscored the importance of comparing fetal size to that of sibling weight. He showed the validity of this concept by showing that 80% of infants affected by congenital rubella were growth restricted in relation to their potential weight, exemplified by that of their normal siblings.
Opinions differ on the optimal strategy for management of fetal growth restriction; this algorithm represents one possible approach. The ratio is normal in the fetus with symmetric growth restriction and elevated in the infant with asymmetric growth restriction.Another important use of ultrasound is estimating the amount of amniotic fluid. For example, there is tendency by physicians to universally use the chart by Battaglia and Lubchenco,15 despite the fact that it is only applicable to pregnant women residing in geographic areas, approximately 6000 ft above sea level. Significant morbidity has been found to exist in pregnancies with an amniotic fluid index value of less than 5 cm.13 The amniotic fluid index is obtained by summing the largest cord-free vertical pocket in each of the four quadrants of an equally divided uterus.
For example, at 36 weeks, a 2100 g neonate born at or near sea level can be approximately placed either in the 15th or fifth centile brackets, depending on which chart is used (Table 3).
Second, in identifying long-term sequelae of IUGR infants researchers have focused on very small neonates, those in whom BW falls below the fifth or third centile.
Amnioinfusion may be of benefit in the presence of a nonreassuring fetal response during labor and a low amniotic fluid index or oligohydramnios. Although this approach is justifiable because it is more likely to show measurable ill effects, it is quite restrictive as it excludes the evaluation and follow up of infants with diminished growth, those who are less severely affected and in whom BW falls at the 15th or even 20th centile.Table 3.
In the face of deteriorating fetal status, a cesarean section should be performed.In subsequent pregnancies, the use of low-dose aspirin may be of benefit in reducing the incidence of IUGR in selected high-risk women. Reprinted with permission from The American College of Obstetricians and Gynecologists.) Furthermore, insufficient attention is directed to the fact that states of normal versus altered growth can be more precisely delineated by evaluation of BW in conjunction with specific growth patterns of the fetal head and body. However, before any of these data are interpreted it is mandatory that physicians become well versed with the definition of predictive value, sensitivity, and specificity of biological tests, and with dependence of the predictive value of tests on prevalence of the disease in specific geographic areas.The use of these tests is illustrated by relating the sonographic finding such as oligohydramnios to the diagnosis of IUGR (Table 4).
Review of this table shows that the sensitivity of oligohydramnios in the diagnosis of growth restriction is 16%. However, the reported sensitivity is correct only to the extent that the incidence of IUGR is 10%. As a result the predictive value and sensitivity of oligohydramnios will be enhanced.Table 4. This latter condition may occur in some pregnancies during the third trimester, rendering the BPD artificially small (Fig. In such situations, unless HC is substituted for BPD, falsely abnormal diagnoses of IUGR can be made.Fig.
The reason is that it encompasses the liver and subcutaneous tissue in that area, both of which show reduction in size secondary to chronic hypoxia and decrease in substrate, associated with IUGR.Fig. In Sabbagha RE [ed]: Diagnostic Ultrasound Applied to Obstestrics and Gynecology, 2nd ed, p 116.

By placing the fetal BPD or HC and AC in specific centile brackets, nine fetal growth patterns emerge. A fetus classified into growth patterns three or six (normal BPD but small AC) is at high risk for asymmetric IUGR. By contrast, a fetus classified into growth pattern nine is at high risk for symmetric IUGR.32 The centile threshold that best delineates states of normal or altered fetal growth, is still undefined. Nonetheless, preliminary observations suggest that by using the 25th centile as a cut-off point the predictive value of growth patterns three, six, and nine in the diagnosis of IUGR is approximately 80%.WEIGHT PREDICTING FORMULASA number of formulas for prediction of BW are now published in the literature. By contrast, the absolute mean % error reflects the variability noted, regardless of sign and as such is a more accurate predictor of differences from actual BW (Table 9).
The format of mean % error can also be misleading because the difference between actual and predicted weights is expressed in small numbers (1–2%) that do not reflect the true variation in BW.
For practical clinical purposes the variation between predicted and actual BWs is best expressed in the form of absolute mean % error per 1000 g (see Table 9).Table 9. It is apparent that the mean % error can be misleading because it artificially reduces the difference between actual and predicted BW. In Sabbagha RE [ed]: Diagnostic Ultrasound Applied to Obstetrics and Gynecology, 2nd ed, p 121. Philadelphia, JB Lippincott, 1987)Comparison of birth weight formulasA variety of formulas are now used for prediction of fetal weight.
