Exploration of the value of B-mode ultrasound in the detection of amniotic fluid for fetus of 41～46+6gestation weeks

Objective To explore the value of B-mode ultrasound in the detection of amniotic fluid(AF) for fetus of 41～46+6gestation weeks.Methods B-mode ultrasound was performed to monitor AF in 232 fetus of 41～46+6 gestation weeks compared with that in 296 fetus of 37～40+6 gestation weeks. Results There were significant differences in amniotic fluid index(AFI), amniotic fluid muddy(AFM) and cavity fetal distress(CFD) between the two groups (P＜0.05 or P＜0.01).Conclusion Though 41 gestation weeks is not the prolonged pregnancy,the reducing AF and the increasing AFM will result in lack of oxygen inside uterus and higher morbidity of CFD,which should be paid more attention to.
