介绍

羊水是一种温暖的液体垫子，可以保护和支撑婴儿在子宫中生长。这种重要的流体包含：

  • hormones
  • immune system cells
  • nutrients
  • hormones
  • 宝宝的尿液

At its highest level, the amniotic fluid in your belly is around 1 quart. After怀孕36周, your fluid levels start to decrease as your body prepares for your baby’s delivery.

当您的医生表演时ultrasoundsprior to delivery, they’ll estimate the amount of amniotic fluid your baby is surrounded by. It’s possible that the fluid may start to leak at some point.

如果过多的液体开始泄漏，则称为寡氢化物。由于羊膜囊破裂，液体也会涌出。这被称为膜破裂。

Sometimes it can be tough to tell if the fluid you are leaking is amniotic fluid. Here’s a look at the symptoms.

什么是正常水平的羊水？

The amount of amniotic fluid cushioning your baby tends to increase as your pregnancy progresses, reaching its highest point at about 36 weeks.

Fluid levels throughout your pregnancy could be around:

  • 60 milliliters (mL) at 12 weeks gestation
  • 175 mL at 16 weeks gestation
  • 400至1,200毫升在34至38周之间

Your doctor can measure your amniotic fluid levels using an ultrasound. There are two calculations on ways to measure, known as the amniotic fluid index (AFI) or the maximum vertical pocket (MPV).

如果您的AFI小于5厘米（CM）或MPV小于2 cm，则医生认为您的流体水平很低。

羊水泄漏的症状

想想您的羊膜囊是水气球。虽然有可能打破水气球，从而引起大量的液体（称为水破坏），但在囊中也可能会出现一个小孔。这可能导致羊水泄漏缓慢。

When you’re pregnant, you may feel like everything leaks: Your bladder becomes fuller faster, and you may leak urine. Your vaginal tissues also may produce extra fluid to help your baby pass more easily. So it can be difficult to determine if fluid is urine, amniotic fluid, orvaginal fluid。

羊水可能具有以下一些特质：

  • clear, white-flecked, and/or tinged with mucus or blood
  • no odor
  • often saturates your underwear

通常，尿液会有气味。阴道液通常是白色或黄色的。

Another way you can try to determine if the fluid is amniotic fluid is to first empty your bladder. Place a sanitary pad or panty liner in your underwear and examine the fluid that is on the pad after 30 minutes to an hour. If the fluid is yellow in color, it’s likely urine. If it isn’t, the fluid could be amniotic fluid.

另一种选择是戴上垫子或内裤衬里，并专注于保持骨盆底肌肉的紧绷，就好像您试图停止尿液一样。如果您这样做并且看不到垫子上的任何液体，那么您看到的液体可能就是尿液。

Risk factors for amniotic fluid leakage

怀孕期间的任何时候，泄漏的羊水对您和您的宝宝都可能是危险的。尽管您可能自然会泄漏少量的流体，但损失过多可能有害。

Leaking amniotic fluid during the first and/or second trimesters can cause complications, including:

在三个月中，低水平的羊水可能引起：

  • difficulties during labor, such as squeezing the umbilical cord, which can affect a baby’s ability to get oxygen
  • 增加风险剖宫产
  • 增长放缓

There are several treatments for low levels of amniotic fluid if yours has leaked too much. Your doctor can advise the best treatment option.

什么时候打电话给你的医生

如果您的液体出现绿色或棕黄色，请立即致电您的医生。这可能表明您的宝宝在子宫中有排便，这可能会在出生时引起呼吸并发症。

You should also call your doctor if you think your membranes may have ruptured, also known as your “water breaking.” You should note the color of the discharge to tell your doctor. You’ll likely be instructed to head to the hospital.

Next steps

估计one-third每小时更换羊水。这意味着即使您正在泄漏羊水，您的宝宝也不会“干”。但是，破裂的膜可能意味着您的输送即将到来和/或可以将细菌引入您的uterus。因此，如果您认为可能正在泄漏羊水，请寻求治疗很重要。
