AMNIOTIC FLUID function amount disorders

                         AMNIOTIC FLUID



                  Amniotic fluid is the protective liquid contained by amniotic sac of gravid amniote. This fluid serves as a cushion for the growing fetus, but also serves to facilitated the exchange the nutrients, water and biochemical products between mother and fetus.

    Initially amniotic fluid is develop by placenta and umbilical cord by the principle of transudate . 

    At the term maximum contribution in amniotic fluid formation given by fetus Urine.

Amniotic fluid amount manage by following -

       * Fetal swallowing - 200 - 500 ml.

       * Urine - 400 - 1200 ml 

       * Pulmonary secretion  300 - 400 ml.

       * Fetal cell contribution up to 20 week .

The amount of amniotic fluid and fetal growth response each other .

      ⮞  12Week                 -       50 ml

      ⮞  16 week                 -       100ml 

      ⮞  20 week                 -       200 ml

     ⮞   36 - 38 week          -       800-1200 ml

     ⮞   40 week                 -       600- 800 ml

     ⮞   42 week                 -       200 ml

Near term and after the term period the amount become decrease, which is related to fetus maturity .

* Ideally amniotic fluid is Isotonic in nature , After the term period it become hypotonic in nature .

COMPOSITION

      Amniotic fluid other content 

      - Urea , uric acid ,creatinine 

      - Amino acid , glucose , fatty acid 

      - Mineral , vitamin , electrolyte 

      - Chromosome , surfactant

      - Meconium ,lanugo , vernix

Nature of fluid

      * Colour less

      * Transparent 

      * Amber 

      * Turbid

      * Pale

PHYSICAL PROPERTIES

     * The Ph of amniotic fluid is 7.2.

     * Normally the fluid is colour less.

Abnormalities of amniotic fluid-

        1. Greenies 

                            Meconium may induce fetal distress 

       2. RED

                        Haemorrhage

        3. Golden colour

                       Indicate haemolysis example - Rh incompatibility

        4. Greenies yellow / Saffron colour

                       Indicate post maturity
