摘要:

ABSTRACTThis study sorts common variables used in dating pregnancy and ranks them according to their level of accuracy. The more accurate predictors, eg, LMP, should need no further corroboration during the course of pregnancy as long as the clinical course remains congruent with gestational length. Less accurate variables, eg, first fetal heart tones or fundal height need further confirmation in the absence of a useful menstrual history.New research is presented on uterine height correlation with gestational age, within the context of related research. Since discrepant uterine size is the most commonly cited reason for ordering ultrasound during pregnancy, this variable was examined in terms of its correlation to gestational age in an effort to define the discrepancy so often cited. Results lead to the conclusion that there is a lack of research data justifying the practice of equating weeks of gestation and centimeters of fundal height. In fact, the data indicate a healthy range of variation and a general tendency for the uterine height to be less than weeks of gestation.The length of the average term pregnancy is examined, with discussion of clinical implications. A management tool is offered to aid the clinician in deciding when further information is needed for a reliable data base. The usefulness of a singular EDD derived by any formula is discussed and the age old Naegele's rule is critically examined and compared to modern studies.

摘要:

ABSTRACTResearch investigating the duration of breastfeeding is generally based on the assumption that if lactation is established, then the mother will breastfeed successfully. Longitudinal, qualitative research suggests, however, that it is the attitude of others towards the breastfeeding mother that determines the duration of breastfeeding. When the infant is a newborn, breastfeeding is encouraged. As the infant develops, the support of others towards the nursing mother is withdrawn and the mother is encouraged to wean. Further, the doula not only facilitates breastfeeding, but also, when the infant is perceived to be “old enough,” facilitates wean

摘要:

ABSTRACTA free‐standing birth center was established in association with a tertiary care hospital that primarily served an indigent population. Initially, all patient assignments were voluntary. Fifteen months later, a change in policy occurred. In order to reduce the overcrowding in the obstetric suite, the hospital assigned low‐risk women to the birth center for maternity care. A study was designed to test the null hypothesis that there would be no difference in outcomes between those who were assigned to the center and those who selected the center for care. One hundred forty‐eight women from each group were matched for parity and demographic variables. The outcome results were analyzed and no differences in outcomes were found. The implications for the future of health care for low‐risk women of poor socioeconomic status are di

摘要:

ABSTRACTA pilot study was undertaken to document differences in care given by nurse‐midwives and physicians to comparable low‐risk pregnant women who delivered at a tertiary care hospital during the spring of 1985. The design used was a case‐comparison retrospective chart review. The sample size was limited to 29 in each study group. Background variables included demographic and prenatal status. Dependent variables included labor, delivery, postpartum care descriptors, and infant and mother outcomes. Particular indicators of the quality of outcomes examined included Apgar scores, complications, length of labor stages, and perineal lacerations. The time of delivery, the mother's age, parity, risk status, and the infant's weight were held constant by the matching procedure. Results indicated that there were no differences in complications, but that very different care practices were experienced by clients of the two types of prov
