Why would someone use an intramuscular injection over another kind?
1 Answer | add yours
There exists three types of injections: intramuscular, subcutaneous and intradermal. The intramuscular injection is preferred over the other two types because it seems to be the best tolerated type.
Although the intramuscular injection is the most easiest to administrate, it is important to follow some basic rules: the length of the needle must be in interval 20 to 22 gauge and the maximum amount of remedy is 5 ml/injection.
The subcutaneous injections are recommended to medicines that need a slower absorption rates than in case of intramuscular injections. By this method, substances that do not irritate the body tissues, are administered in adipose tissues.
For example, insulin and some vaccines are given subcutaneously. The length of the needle used must be between 23 to 25 gauge and the volume of remedy administered is no larger than 1ml.
The intradermal injections are used for tuberculin and allergy testings. This type of injection usually places a small amount of allergen or antigen under the skin. The sting is made right under the surface of the skin, between its layers.
