What symptom does 5 years old child hypocalcemia have

summary

Clinically, some patients with allergic diseases and rickets caused by low blood calcium in children, often given oral or injection of calcium gluconate and other calcium preparations, this is one aspect of calcium application, but the physiological function of calcium is far more than these, the following on its distribution in the body and the main physiological function from two aspects to make an introduction.

What symptom does 5 years old child hypocalcemia have

First: inhibition of neuromuscular excitability: calcium ion has the effect of reducing neuroskeletal muscle excitability. When the concentration of blood calcium is lower than 7.0 mg, neuroskeletal muscle excitability will be improved. Therefore, rickets patients may have symptoms such as hand and foot convulsions and convulsions.

Second: participate in muscle contraction: calcium has a direct relationship with skeletal muscle contraction, and also plays a very important role in maintaining normal myocardial contraction. Excessive calcium may cause muscle tension, slow heartbeat and even cardiac arrest.

Third: to participate in the process of blood coagulation: because of this reason, in order to prevent blood coagulation, anticoagulants such as sodium citrate or potassium oxalate are often added to the blood. Citric acid and oxalic acid can combine with calcium in the plasma, making it lose the role of promoting blood coagulation.

matters needing attention

Maintain the normal permeability of cells and reduce the permeability of capillaries. This is the reason for calcium injection in some allergic diseases.
