Vibroacoustic stimulation (VAS), sometimes referred to as fetal vibroacoustic stimulation or fetal acoustic stimulation test (FAST), is the application of a vibratory sound stimulus to the abdomen of a pregnant woman to induce FHR (fetal heart rate) accelerations.
A biophysical profile (BPP) is a prenatal ultrasound evaluation of fetal well-being involving a scoring system, [1] with the score being termed Manning's score. [2] It is often done when a non-stress test (NST) is non reactive, or for other obstetrical indications.
A contraction stress test (CST) is performed near the end of pregnancy (34 weeks' gestation) to determine how well the fetus will cope with the contractions of childbirth.The aim is to induce contractions and monitor the fetus to check for heart rate abnormalities using a cardiotocograph.
A biophysical profile is a noninvasive procedure that uses the ultrasound to evaluate the fetal health based on NST and four ultrasound parameters: fetal movement, fetal breathing, fetal muscle tone, and the amount of amniotic fluid surrounding the fetus. A score of 2 points is given for each category that meets the criteria or 0 points if the ...
Invasive carcinoma NST is a diagnosis of exclusion, which means that for the diagnosis to be made all the other specific types must be ruled out. There are several rare sub-types of invasive carcinoma NST including pleomorphic carcinoma , carcinoma with osteoclast-like stromal giant cells , carcinoma with choriocarcinomatous features , and ...
NST: non-stress test (see cardiotocograph) NSTEMI: non-ST-elevation myocardial infarction: NSU: nonspecific urethritis: NSVD: normal spontaneous vaginal delivery NT: not tested nontender nuchal translucency NTBS: needs to be seen NTD: neural tube defect NTG: nitroglycerin: n/t: numbness and tingling NTP: Nortriptyline: NTS: nucleus tractus ...
Fetal distress, also known as non-reassuring fetal status, is a condition during pregnancy or labor in which the fetus shows signs of inadequate oxygenation. [1] Due to its imprecision, the term "fetal distress" has fallen out of use in American obstetrics.
