Severe postpartum pain

The severe postpartum labor pain is caused by oligohydramnios, etc. The postpartum pregnancy results in severe labor pains. Those with less than 300ml of amniotic fluid in late pregnancy are called oligohydramnios. There are too few amniotic fluid in early and middle pregnancy, and most of them end in abortion. When there is too little amniotic fluid, the amniotic fluid is thick, cloudy, and dark green. The incidence of oligohydramnios was thought to be about 0.1% in the past, but due to the widespread use of B-mode ultrasound in recent years, the detection rate of oligohydramnios was 0.5% to 4%, and the incidence increased. Poor amniotic fluid seriously affects the prognosis of perinatal infants and is valued.
