Almost all parents at least once in their life have marked the blueing of the nasolabial triangle in their infants. It occurs both in healthy children, and in those who have problems in the work of the cardiovascular system, as well as the central nervous system.
What makes a blue complexion appear?
Normally, the oxygen saturation of the baby's blood reaches 95%. During physical exertion, such as screaming and crying for crumbs, the indicator decreases to 90-92%, as a result of which the nasolabial triangle becomes blue in the baby . This phenomenon was called cyanosis.
Blueing of the nasolabial triangle in healthy babies
In the first weeks of the life of the baby, blueing of the nasolabial triangle is not uncommon. This phenomenon is called pulmonary cyanosis and occurs when the baby is physically stressed. It usually takes 2-3 weeks. If this phenomenon persists, and the cyanotic nasolabial triangle appears again and again, the mother must necessarily show the baby to the doctor.
Also, the cause of the blue nasolabial triangle in the infant may be the proximity of the blood vessels to the surface of its thin skin. This phenomenon is not cause for concern.
Blueing of the nasolabial triangle - pathology
Often the nasolabial triangle of the baby becomes blue due to the development of severe diseases of the respiratory system. An example is pneumonia or complicated pathologies of the lungs. These diseases are accompanied by pale skin, severe paroxysmal breathing. And the stronger the attack, the more pronounced cyanosis.
However, after the end of such an attack, the skin around the nasolabial triangle in the baby quickly whitens.
Quite often the phenomenon of this symptom in the baby indicates the ingress of foreign body into the respiratory tract. At the same time, the breath becomes difficult, and the child begins to choke. In such situations it is necessary to help the child as soon as possible.
If the blueness does not pass a long time, then the mother should apply for an explanation of the cause to the doctor. In this case, the diagnosis of the heart system using ultrasound. Also perform lung diagnostics using an X-ray.
Thus, the blue nasolabial triangle can be a manifestation of both the pathological process and the peculiarity of the physiological structure of the skin of the infant.
