During the entire pregnancy period, the fetus is in the aquatic environment - it is a bladder filled with amniotic fluid, they are also called amniotic fluid . Until the time of birth, this bubble performs many functions - softens the tremors, participates in the fetal metabolic processes, provides preparation for the normal functioning of newly formed organs. When the time of childbirth is coming, the bladder ruptures - and the entire amniotic fluid goes out - this process is called the "flow of water".
About the number of amniotic fluid and the norm
With a planned ultrasound, the doctor necessarily evaluates the amount of amniotic fluid, compares it with the rate for a given pregnancy and monitors possible changes in their composition. The norm and amount of amniotic fluid are calculated for each gestation period and are presented in the table below:
The data given in the table are approximate, since the doctor directly evaluates this indicator individually during ultrasound, considering the general condition of the pregnant woman and all the health indicators of her and the baby in the womb. Amount of amniotic fluid varies widely and the norm in this case is a relative term. The table gives only an idea of the limits of the norm of amniotic fluid, therefore the final diagnosis is made only by a doctor based on ultrasound.
The norm of amniotic fluid is one of the most important concepts in obstetrics, since this indicator is a reliable marker of the pathology of pregnancy. When the functioning of the provisional organs of the fetus is disrupted, polyhydramnios are most often observed, with pathology on the part of the mother's body - often there is malnutrition. Mnogovody in pregnant women consider such an index of amniotic fluid, which exceeds the norm (in this case - the upper limit of the range) by 1.3-1.5 times. Malnutrition (a quarter less than the lower limit of the norm) is fraught with complicated childbirth and birth trauma of the child. Polyhydramnios are as dangerous as the threat of rupture of the uterus and pelvic presentation of the fetus.
