It is usually used when the drug should not be taken orally, the sick child cannot take the drug or when the rapid effect of the drug is required according to the condition. In general, although intramuscular injection is performed by a nurse, as a parent, it should also assist in good nursing work.

(7) Local lumps caused by drugs after intramuscular injection can be absorbed by hot compresses or moxa sticks.

The general route of transmission of drugs into the body

After the drug is dissolved in the interstitial fluid, it enters the capillary network and then into the vein or directly into the small vein or into the lymph fluid and then into the large vein. The venous blood enters the right atrium and then into the right ventricle. After pulmonary circulation, it returns to the left atrium. The left ventricle enters the systemic circulation, reaches the liver, metabolizes active ingredients, and then reaches the whole body or lesion with blood flow. If it is active without metabolism, it can go directly to the whole body without entering the liver.
