The normal value of platelets is (100-300)*10^9/L. When it is lower than 100*10^9/L, platelets are low.
Vigilance is needed when the platelet count is lower than 20*10^9/L, or when the platelet count is greater than 20*10^9/L but accompanied by obvious bleeding manifestations such as blood in the stool, hematuria, active bleeding from the gums or nasal passages.
Platelets mainly play the role of hemostasis in the body, when the platelet count is severely reduced, there may be petechiae and ecchymosis of the skin and mucous membranes, bleeding of the mucous membranes of the gums and nasal passages, black stools or blood in the stools, hematuria and other bleeding manifestations, and in severe cases, spontaneous intracranial hemorrhage may occur and become a life-threatening condition.
The lower the platelet count, the higher the risk of bleeding complications and the more serious the condition. When the platelet count is lower than 20*10^9/L, the risk of intracranial hemorrhage is significantly increased, so it is necessary to be vigilant, and should be immediately given the same blood type single platelet intravenous transfusion, and at the same time, actively identify the causes of thrombocytopenia, and then target the cause of the treatment to improve the platelet count.
In addition, if the patient has obvious bleeding manifestations such as blood in stool, hematuria, active bleeding from the gums or nasal cavity, even if the platelet count is greater than 20*10^9/L, it is necessary to be vigilant, and intravenous platelet transfusion can be given, and active platelet-boosting therapy.
It is recommended that thrombocytopenic patients should consult the hematology department in time, and the treatment should be directed at the cause of the disease after the cause of the disease is actively clarified.
