The Isolated Oligohydramnios

Amniotic fluid is an indicator of normal placental function and is essential for normal fetal lung maturation. Amniotic fluid index (AFI) is the most preferred method of amniotic fluid measurement in pregnancy although single deepest pocket (SDP) is also used. To measure AFI, the examiner divides the uterus into four equal quadrants. AFI is the sum of deepest pocket from each quadrant. The normal AFI ranges between 5~24 cm while any value above 24 cm is considered as hydramnios and that below 5 cm is indicated as oligohydramnios. An adequate volume of amniotic fluid is critical to allow normal fetal movement and growth, while also cushioning the fetus and umbilical cord. Regardless of the etiology, oligohydramnios may inhibit these processes and may lead to fetal deformation, umbilical cord compression, and death in some instances. Oligohydramnios can be due to underproduction, loss, or sometimes, isolated. Isolated oligohydramnios has been found to be responsive maternal hydration and is neither a malformation of the urinary system in the fetus, nor a rupture of amnion and due to genetic cause. The author would like to introduce a way to increase amniotic fluid volume in isolated oligohydramnios which is expect to improve the perinatal outcomes.

Effects of combination of maternal hydration and hands and knees posture on nursing of breech pregnancy / 中国实用护理杂志

Objective To compare the effects of combination of maternal hydration and hands and knees posture with simple hands and knees posture on correction of breech pregnancy. Methods One hundred patients who were diagnosed breech pregnancy from November 2015 to November 2016 were assigned to experimental group and control group with 50 cases each according to individual willingness. The patients in experimental group received the combination of maternal hydration and hands and knees posture;while the patients in control group received simple hands and knees posture. Results Amniotic fluid index was (18.94±2.44)cm in experimental group and (15.97±2.33)cm in control group, the difference had statistic significance (t=6.239, P<0.05). The effective transfer rate and successfully used time was 92%(46/50) , (2.10 ± 0.75) weeks in experimental group and 64%(32/50), (4.27 ± 0.98) weeks in control group, the difference had statistic significance (χ2=11.422, P<0.05; t=-12.463, P<0.05). For primipara and multipara, the effective transfer rate was 90.91%(30/33), 16/17 in experimental group, and 68.75%(22/32), 10/18 in control group, the difference had statistic significance (χ2=4.986, 6.806, all P<0.05). The rate of vaginal and cesarean section deliveries was 86%(43/50), 14%(7/50) in experimental group, and 56%(28/50), 44%(22/50) in control group, the difference had statistic significance(χ2=10.928, P=0.001). Patients who had fetal movement or who didn′t have time to do correction or missed was 17.10%(46/269), 1.49%(4/269) in experimental group, and 12.55% (22/255), 7.06% (18/255) in control group. Conclusions @Therapic effects of combination of maternal hydration and hands and knees posture is much better than that of the simple hands and knees posture therapy on correction of breech pregnancy, which is worthy of popularization and application in clinic.
