Introduction

In general, artificial rupture of membranes (ARM) can be used as a method for managing polyhydramnios. ARM involves artificially rupturing the fetal membranes to trigger the release of prostaglandins and oxytocin, thereby inducing uterine contractions to achieve labor induction. During this process, the excessive amniotic fluid can drain slowly, helping to reduce the amniotic fluid volume.

Generally, artificial rupture of membranes (ARM) can be used as a method for managing polyhydramnios. The detailed explanation is as follows:

ARM involves artificially rupturing the fetal membranes to induce the release of prostaglandins and oxytocin, thereby triggering uterine contractions and achieving the goal of labor induction. During this process, as the membranes rupture, the excess amniotic fluid can slowly drain out, helping to reduce amniotic fluid volume and decrease the risks associated with polyhydramnios for both the fetus and the mother.

However, when the volume of amniotic fluid is extremely high, or when fetal abnormalities, placental insufficiency, or other complications exist, ARM may carry greater risks, such as umbilical cord prolapse, infection, and fetal distress. In such cases, other methods of induction, such as medical induction or cesarean section, should be considered under the guidance of a physician to ensure the safety of both mother and baby.

Pregnant women are advised to appropriately reduce their daily water intake and avoid excessive fluid consumption and foods with high water content, such as watermelon and cucumber, to prevent further increase in amniotic fluid volume.

What does fetal position breech mean?

The normal fetal position should be cephalic, meaning the fetal head is facing downward with the occiput approaching the maternal pelvic inlet. In contrast, breech position is a type of abnormal fetal presentation. This condition may occur when the fetus has excessive space for movement within the uterus, such as in cases of polyhydramnios, or insufficient space, for example due to uterine malformation or pelvic narrowing, preventing the fetus from normally rotating into a cephalic position.

What are the symptoms of gestational diabetes?

In general, gestational diabetes refers to diabetes that occurs during pregnancy. Gestational diabetes may be accompanied by symptoms such as excessive thirst, increased appetite, blurred vision, fatigue, and polyhydramnios (excess amniotic fluid). It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Pregnant women are advised to maintain a balanced diet during pregnancy and avoid consuming excessive amounts of high-sugar and high-fat foods.

What to do about a fetus in a transverse position

In general, fetal oblique position may be caused by factors such as不良 living habits, abnormal uterine shape, excessive tension in the abdominal muscles or uterine ligaments, polyhydramnios or oligohydramnios, multiple pregnancies, and so on. It can be improved through general treatment, medication, surgical treatment, and other methods. During pregnancy, pregnant women should maintain a healthy lifestyle and visit the hospital regularly for follow-up examinations.

What is the impact of an enlarged gastric bubble on the fetus?

The impact of an enlarged fetal stomach bubble should be evaluated on a case-by-case basis. It may include physiological conditions with no adverse effects, gastrointestinal malformations affecting nutrient absorption, risks associated with chromosomal abnormalities, indirect effects due to polyhydramnios, or misdiagnosis/measurement errors that require no concern. In most cases, there is no need for alarm, although a minority may require further intervention. Maintain regular daily routines and a balanced diet.
