Fetal biophysical phase score

Fetal Biophysical Phase Score (BPS) was developed in the 1980s by Manning et al. to develop a method for ultrasound monitoring of high-risk fetal behavior, including fetal movement (FM), fetal respiratory movement (FBM), non-irritation test (NST), and fetal muscle. There are 5 items of tension (FT) and amniotic fluid volume (AFV). Vintzileos et al. improved the Manning scoring method, increased the placental grading (P), and studied the correlation between BPP and PPROM concurrent infection; NST non-responsive type and FBM deficiency are the main manifestations of fetal recessive infection, while FM and FT are reduced. It is a sign of late infection. Fetal infection can increase the fetal oxygen demand. On the one hand, it causes acidosis in the fetus. On the other hand, the local brain tissue is in a hypoxic state, leading to central nervous system dysfunction and BPP changes. BPP can be widely used in PPROM patients to predict fetal safety and intrauterine infection. NST is an indispensable indicator in BPS, and its negative predictive value is the same as BPP with NST alone.

Basic Information

Specialist classification: prenatal and postnatal examination classification: ultrasound

Applicable gender: whether women are fasting: not fasting

Tips: Actively cooperate with the doctor's work. Normal value

Fetal biophysical phase score, the score is 10 points, below 6 points suggest fetal hypoxia.

Clinical significance

Abnormal results: fetal infection, intrauterine infection, fetal hypoxia, etc.

People who need to be examined: pregnant women and people who need to have a fetal development check.

Precautions

Taboo before the examination: poor rest, improper diet, excessive fatigue.

Requirements for inspection: Actively cooperate with the doctor's work.

Inspection process

B-ultrasound examination is performed first, and the result data is analyzed for the fetal biophysical phase score.

Not suitable for the crowd

No taboos.

Adverse reactions and risks

No related complications and hazards.
