The biophysical profile is more carefully with any diverse single assessment operating. The score scope from 2-10, with 10 as the highest. If the fetus shall a score off 8 to 10, it is doing well. If the tally is 6, this is considered suspicious.
WebPhosphatidylglycerol (PG) and lecithin/sphingomyelin ( L S) ratios were stimultaneously determined in 1770 samples of amniotic fluid. PG was defined as "present" when it appeared in at least 2% of the total phospholipids. WebApr 15, 1979 · Surfactant contains other phospholipids besides lecithin, including phosphatidylglycerol (PG), the second major component of mature surfactant. Ninety …
WebPhosphatidylglycerol is a minor constituent of surfactant that generally appears several weeks after the increase in lecithin concentration. Because PG enhances the spread of phospholipids on the alveolar surface, its presence indicates an advanced state of fetal pulmonary maturity. WebAmniotic fluid phospholipids (lecithin, sphingomyelin, phosphatidylglycerol) were extracted and separated by the method of Gluck and associates. In addition, these lipids were quantified against standards that were concurrently developed in three adjacent thin layer chromatography (TLC) channels.
