P56.9: Hydrops fetalis due to other and unspecified haemolytic disease

Blood is made up of a liquid part and different blood cells, among other things. The blood cells include the red blood cells, the white blood cells and the platelets. The red blood cells carry oxygen from the lungs throughout the body. Red blood cells contain the red hemoglobin that gives blood its color. This pigment is important for carrying oxygen in the blood.

If the red blood cells get damaged or changed, for example, they will increasingly be broken down in the body. There is then too little red blood pigment in the blood, and not enough oxygen can be transported. This can seriously damage the child's health.

Fluid then accumulates around the child's heart and lungs, or in its abdomen. Fluid can also accumulate in the skin. The child may move less than usual in the womb. The child's heart may also beat unusually quickly. Newborn babies can have breathing problems. The skin may look pale or yellowish.
