Fetal blood velocity waveforms

American Journal of Obstetrics and Gynecology, 1978
In this paper a method is described for obtaining and characterizing fetal blood velocity waveforms. The signals were recorded with a range-gated Doppler instrument and characterized after spectral analysis. Preliminary observations indicate differences in the waveforms obtained during normal pregnancies compared with some complicated pregnancies.

Cytogenetic Studies in Fetal Blood

Fetal Diagnosis and Therapy, 1998
In order to assess the effectiveness and reliability of cytogenetic diagnosis provided by fetal blood, we report the first 186 cases of fetal blood sampling performed for rapid karyotype between 19–37 weeks of pregnancy in our Prenatal Diagnosis Unit.

Fetal scalp blood sampling

Journal of Nurse-Midwifery, 1993
Fetal scalp blood sampling (FSBS), in conjunction with fetal heart rate monitoring, is a method of fetal surveillance that may avoid cesarean delivery of the healthy fetus or indicate the need for immediate delivery of a compromised fetus. Some researchers have recently begun to question the efficacy of FSBS.

Fetal Blood Sampling and Its Complications Related to the Indications for Fetal Blood Sampling

Australian and New Zealand Journal of Obstetrics and Gynaecology, 1993
Summary: A prospective study on fetal blood sampling (FBS) was conducted in the Fetomaternal Medicine Division of the Department of Obstetrics and Gynaecology at the National University Hospital, Singapore. FBS was performed on 159 occasions in 156 women between January, 1988 and December, 1991.

Reliability of fetal blood sampling

American Journal of Obstetrics and Gynecology, 1970
Abstract Samples of capillary blood were obtained serially from 355 fetuses and the acid-base components analyzed. A good correlation was found between the pH of fetal capillary blood and the clinical state of the infant at birth, as judged by the one-minute Apgar score.

Blood Gas: Fetal

2017
Blood gas analysis of a fetus can represent the fetal condition in utero and sometime help the obstetrician to decide on the mode of delivery. It can be assessed antepartum, intrapartum, or postpartum via a number of ways. Umbilical cord blood gas analysis is routinely ordered by obstetricians at the time of delivery if there is suspicion of neonatal ...

Fetal blood studies

American Journal of Obstetrics and Gynecology, 1959
Abstract The range of variation in the oxygen dissociation curves of blood of nonpregnant women and of pregnant women has been determined at the same pH—the latter falls within the range of normal nonpregnant individuals. The curves of fetal blood obtained at the end of gestation are to the left of the adult field.

Amnioscopy and Fetal Blood Sampling [PDF]

open access: possible, 1968
Whenever examination of the mother during the last six weeks of pregnancy leads to the suspicion that the fetus might be endangered by chronic lack of oxygen, direct examination of the amniotic fluid is indicated (Saling, 1962). A special conical endoscope is passed into the cervical canal so that amniotic fluid can be inspected through the intact ...

Invasive Fetal Assessment by Fetal Blood Sampling

1990
The development of the discipline of maternal-fetal medicine has been hampered by the lack of direct access to the fetus. With the development of high-resolution, real-time ultrasound, we have acquired a way to perform a “physical exam” of our fetal patients, but the idea of a modern internist or pediatrician making diagnoses or administering ...
