“…After delivery, capillary glucose estimations were performed on the neonates with a reflectance meter every 2 h for the first 12 h of life. The biparietal diameters (BPDs), crown-rump length (CRL), trunk area (TA), and fetal volume (CRL X TA) were measured with a conventional static scanner with an attached semiautomated area-and perimeter-measuring device (17). This device only became available in our clinic midway through this study, and therefore TA and fetal volume measurements were not recorded in all pregnancies.…”

Macrosomia in Pregnancy Complicated by Insulin-Dependent Diabetes Mellitus

We assessed the factors influencing the birth weight of infants born to 83 women with insulin-dependent diabetes mellitus (IDDM) over a 5-yr period. Maternal glycosylated hemoglobin (HbA1) concentrations at delivery correlated with the percentile birth-weight ratios (r = .43, P less than .001) and indicated that approximately 18% of variance in the birth weight could be ascribed to glycemic control in the third trimester. Fetal macrosomia occurred in 22 (27%) pregnancies. When 20 of these pregnancies were compared closely with 20 nonmacrosomic pregnancies in diabetic women, the mothers of macrosomic infants were found to be more obese, have a history of previous macrosomic birth, and have higher concentrations of serum human placental lactogen and urinary estriols in the third trimester. Macrosomic pregnancy was further distinguished by accelerated fetal growth (judged by serial ultrasonography) from the 32nd wk of gestation and by biochemical (but asymptomatic) hypoglycemia in the neonate. In our study, no serious neonatal morbidity could be attributed to macrosomic pregnancy. Good glycemic control was attained in both groups, and no significant differences between the groups in overall glycemic control throughout pregnancy were noted. Thus, despite good glycemic control, macrosomia remains comparatively common in modern pregnancy complicated by IDDM, and factors other than maternal hyperglycemia must contribute to its etiology.

“…The two-stage ultrasound examination schedule assessed in this study comprises accurate assessment of gestational age in early pregnancy followed by assessment of fetal size at 34 to 36 weeks. The first-stage examination, which is vital for interpretation of the results of the secondstage examination, is incorporated in our routine policy of making an ultrasound examination on all patients when they first attend the antenatal clinic; the other advantages of this policy have been discussed previously (Neilson & Hood 1980;Neilson et al 1982).…”

Summary. Calculation of the product of crown‐rump length and trunk area (CRLxTA), as measured by ultrasound between 34 and 36 weeks and combined with accurate assessment of gestational age in early pregnancy, was previously shown to be highly effective in detecting the small‐for‐dates fetus in a largely unselected series of patients. To assess the value of this two‐stage schedule in high‐risk pregnancies, 202 patients with singleton pregnancies at risk of fetal growth retardation were studied. Of the 53 babies that were small‐for‐dates at birth, 49 (92%) were identified in advance by CRLxTA measurement. In contrast to previous findings, measurement of trunk area (TA) alone was similarly effective, identifying in advance 48 (91%) of these small‐for‐dates babies.

“…More recently, measurement of the diameters, circumference, and cross-sectional area of the chest and abdomen at various levels has been described and recommended . Neilson and Hood (1980) found that fetal growth could be assessed more accurately by combining trunk measurements with what they term direct CRL measurement. This is merely a linear measurement that does not take account offetal flexion.…”
