In connection with the fact that the subcutaneous fat layer is richly supplied with blood vessels, for the quick action of the drug substance, subcutaneous injections are used. Usually, drug solutions are injected, which are quickly absorbed by loose subcutaneous tissue and do not have harmful effects on it.
With subcutaneous injection, the absorption of medicinal substances, and consequently, in the manifestation of the therapeutic effect, is slower than with intramuscular and intravenous. However, they are more effective in this case. When the peripheral circulation is insufficient, the injected substances are poorly absorbed.
The introduction of subcutaneous injections is not particularly difficult. But to achieve a positive effect in the treatment and eliminate possible complications, it is necessary to follow the proposed algorithm exactly. It should be remembered that any manipulation associated with damage to the skin requires careful handling and sterilization. If the puncture site still formed a seal, it will help remove the iodine grid or compress with magnesium.
