It is possible to produce in the first days of the premature babies of less than 34 weeks. If the hemorrhage is small it is solved and does not leave injuries but if it is big a pressure increase takes place in the central cavities of the brain (cerebral ventricles), and to give problems for the compression of the brain that if it is not solved rapidly will leave permanent aftermath. It is possible to diagnose for ultrasound scan and they are solved by a drainage of the ventricles that prevents the pressure of the blood from increasing on the brain. If the accumulation is small it can be a question with certain medicines and control ecográfico of the evolution.

During the pregnancy the fetus tends to accumulate iron in deposits to use them after the birth in the production of red globules or eritrocitos. If the childbearing goes forward it is a storage it has not been realized in its entirety and as it the baby will have an anemia ferropénica. The absence of active red globules for the oxygen transport worsens other situations of absence of pulmonary or cardiac functioning, therefore it aggravates the situation of the premature baby.

The diagnosis is realized by means of blood test and talks each other with supplements of iron, stimulating of the formation of eritrocitos (EPO), or in serious cases with blood transfusions.

The immaturity and the absence of blood irrigation can affect to the intestinal textile of the premature baby, since this textile makes exposed to the intestinal bacteria without a defense of the proper intestinal textile against them.

It is possible to provoke thus an intestinal alteration at 2 a.m. ó 3 weeks of the childbearing that does not absorb the meals and produces a persistent diarrhea.

By means of studies in blood and radiographies it goes over to the diagnosis and talks each other with antibiotics and feeding parenteral (endovenosa) to allow to rest and to recover to the intestinal mucous membrane. In serious cases the injury is intense and not recoverable, being precise the surgery to cut the intestinal part rendered useless to leave the fierceness or convalescent one.

In these cases that are usually in premature babies of less than 32 weeks, the immaturity and injury they present before themselves in the textile of the cornea of the eye.

An exaggerated veins growth appears in the eye, and hemorrhages in the retina, staying scars in the same one resulting in blurry vision or inclusive blindness.

It is diagnosed by means of an ophthalmoscope and exploration of the interior of the eye.

The treatment is conservative and the evolution is usually good in most of the cases. In that injuries stay, and so that they do not spread, skills can be applied to isolate areas without injury (laser, crioterapia) in the retina and to support certain preserved vision.

The immune system or of defenses also it is immature and by it the premature baby is exhibited and more capable to different viruses and bacteria.

This way there usually have pictures of pneumonias, meningitis, or general infections or sepsis that can affect him more than to a normal newborn baby for the complications of other immature organs.

The preventive treatment of isolation of the premature babies is fundamental with the sanitary team and with the family of the premature baby.

If it already has the infection it will talk each other with antibiotics, antiviral medicines and other necessary symptomatic medicines in every case.
