Dengue Patients Don’t Die of Platelet Deficiency




As per international guidelines, unless the platelet count is less than 10000 and there is spontaneous active bleeding, no platelet transfusion is required, said Dr. K.K. Aggarwal, President, Heart Care Foundation of India.

Dr. Aggarwal said that the cause of death in dengue is capillary leakage causing blood deficiency in vascular department, leading to multi organ failure. At the first instance of plasma leakage from intra vascular compartment to extra vascular compartment, one need to give 20 ml per kg body weight per hour of fluid replacement to the patient till the difference between upper and lower blood pressure is more than 40 mmHg or the patient passes adequate urine.

Giving unnecessary platelet transfusion to the patient can harm the individual. Dr. Aggarwal further said that in the city there is a panic amongst the family doctors and patients for running after getting platelet transfusion done.

Dr. Aggarwal has created a formula of 20 for the family doctors to understand the severity of dengue.

a.        There is a rise in pulse by 20

b.        Three is a fall in upper Blood Pressure by 20 mmHg

c.        The pulse pressure is lower than 20

d.        The Hematocrit increased by 20%

e.        Platelet count is less than 20,000

f.      There are more than 20 petechiae in the tourniquet test
