Sudden appearance of small red spots around eyes
In polyclinics, parents often encounter parents and children rushing to see a doctor: “Doctor, why did so many small red dots suddenly appear around my child’s eyes, like bleeding spots!” At this time, doctor will ask, "Did child cough a lot? Did he cry loudly? Did he vomit?" "Yes, yes, yes, in morning there was vomiting, and then there were small red spots."
These small red spots are called hypertensive purpura, also known as mechanical purpura, which is more common in children.
What does mechanical purpura look like?Suddenly, pitted, clustered, or scattered petechiae or bruises appear around eyes or on cheeks that do not disappear when pressed, and there may also be severe loosening of tissues, such as neck and chest.
Why does mechanical purpura occur?
Due to sudden and violent contraction of local muscles, internal pressure in local small blood vessels and capillaries rises sharply, leading to rupture of small blood vessels and extravasation of red blood cells, causing purpura. Common factors that lead to increased intravascular pressure include upper respiratory infections, gastrointestinal flu, severe coughing, vomiting, exercise, childbirth, convulsions, convulsions, constipation, crying, and playing musical instruments.
Need treatment?
Hypertensive purpura of intravascular pressure does not require special treatment, and skin lesions may disappear within a few days after pressure disappears. Symptomatic treatment can be carried out with severe cough, vomiting, constipation, etc. to prevent vascular internal pressure increased dramatically.
Does it need to be distinguished from other types of purpura?
Hypertensive intravascular pressure purpura can be differentiated from other types of purpura such as idiopathic thrombocytopenic purpura, secondary thrombocytopenic purpura, thrombocytopenic purpura, etc. The main method of identification is physical examination and history taking, as well as routine blood tests and determination of function blood clotting. examination was used to rule out diagnosis, and routine blood and coagulation tests were normal.
The following is a list of various causes of mechanical purpura that I encountered in the outpatient clinic: loud crying, coughing, vomiting, heavy bowel movements with constipation, and handstands while dancing or yoga.
