Umbilical velocimetry in normal pregnancy
International Journal of Gynecology & Obstetrics, 1990AbstractFive hundred ninety‐six normal pregnancies were evaluated with continuous Doppler to determine the changes in velocimetry between 17 and 42 weeks gestation. The waveform was identified by its characteristic sharp systolic rise and slow diastolic decay; plotting the S/D ratio as a function of the gestational age reveals a progressive decline in ...

Albumin Metabolism in Normal Pregnancy
Scandinavian Journal of Clinical and Laboratory Investigation, 1968Albumin metabolism was studied in 19 normally pregnant women and 11 healthy, non-pregnant women.In pregnancy plasma volume was significantly higher, serum albumin concentration significantly lower than in controls. The intravascular mass of albumin was normal.The fractional catabolic rate and the rate of synthesis were not different from those of ...

Fibrinopeptide a During Normal Pregnancy
American Journal of Perinatology, 1988Fibrinopeptide A (FPA) is the first peptide released from fibrinogen upon thrombin action. Plasma FPA is cleared rapidly with a first order kinetics and therefore its level reflects the rate of thrombin cleavage of fibrinogen. A prospective study was undertaken to establish normal values of FPA during pregnancy. The mean FPA for the pregnant group (n =

It is important to use consistent terms when describing the age of a conceptus. While gestational age in embryology is measured from the time of fertilization, the reference point in obstetrics is the start of the last normal menstrual period. Thus the duration of pregnancy is stated in terms of menstrual age and is measured in weeks.

SERUM OESTRIOL IN NORMAL PREGNANCY
BJOG: An International Journal of Obstetrics & Gynaecology, 1976SummarySerial measurements of serum oestriol (E3) were made in 56 normal pregnancies from 10 to 40 weeks gestation using a radioreceptor assay. Several parameters of the assay and its intrapatient variability were examined. The mean curve for pregnancy E3 levels and limits of normal variation have been identified and compared with those of other series.

Endocrine changes in normal pregnancy
The American Journal of Medicine, 1955Summary The various changes that occur in hormone secretions during pregnancy have been reviewed. The first trimester is characterized by a rapid rise in levels of chorionic gonadotrophin in blood and urine. The function of the adrenal cortex is slightly increased at this time.

The clinician is often consulted to examine a pregnant woman for the presence of cardiovascular disease. Delineation of heart disease during pregnancy may be especially difficult, as the considerable hemodynamic changes that occur during normal pregnancy typically produce signs and symptoms that mimic cardiovascular disorders.

Nutritional Requirements in Normal Pregnancy
Diabetes Care, 1980Additional intakes of virtually all nutrients are needed for the support of pregnancy. Energy requirements average 300 kcal/day above nonpregnant needs, which should provide for a weight gain of 400 g/wk during the last two trimesters. Total protein intake of 1.3 g/kg/day is recommended for the adult gravida.

Cardiorespiratory Alterations During Normal Pregnancy
Critical Care Clinics, 1991Maternal cardiorespiratory changes can hinder satisfactory evaluation of gravid women. Alterations in the maternal cardiorespiratory system may be further modified by pain, labor, surgery, maternal posture, and gestational age. Critical illness during pregnancy demands an aggressive multidisciplinary approach by health care professionals who are ...
