Fetal biophysical scoring, mainly to determine the fetal health status. Biophysical monitoring of the fetus, including the stress-free test and ultrasonography, is aimed at understanding intrauterine hypoxia and acidosis in the fetus. The biophysical score is divided into five main items: the first one, is the stress-free test. The first is the stress-free test, which involves 20 minutes of fetal heart monitoring, followed by a score of 2 for normal and 0 for abnormal. The second item is to look at the fetal respiratory movement under ultrasound, observe for half an hour, normal is also 2 points, abnormal is 0 points. The third item, is 30 minutes of fetal movement, if normal is also 2 points, and then abnormal is 0 points. The fourth item is to determine the muscle tone of the fetus, this is also monitored under ultrasound. If more than one trunk or limb extension and re-flexion, finger spreading and closing, then it is considered normal, and the normal is 2 points. If the fetus is not moving, the limbs are fully extended, or the extension is slow, the fetus is considered to have abnormal muscle tone, which is a score of 0. The fifth item, amniotic fluid volume, the maximum vertical depth of the dark area of amniotic fluid is normal, that is 2 points, if abnormal, it is 0 points. This score is out of 10 points, 10-8 points, consider no acute or chronic hypoxia; 8-6 points, consider acute or chronic hypoxia; 6-4 points, consider acute or chronic hypoxia; 4-2 points, consider acute hypoxia with chronic hypoxia; 0 points, consider acute or chronic hypoxia. This biophysical score is used to determine the well-being of the fetal baby.
