The difference between anal injection and injection

Many people don’t know much about anal injection. In fact, this is an enema treatment, which is often used for enema treatment of infants and young children. It has certain advantages, that is, it is not easy to cause pain and the treatment effect will be better. Of course, it also has certain disadvantages, that is, it is easy to cause adverse reactions in the intestines and easily induce some intestinal diseases. We are more familiar with ordinary injections. This is a method of intramuscular injection. Let us learn about it.

The difference between anal injections and injections

Generally, children are given enema for treatment. Enema does not cause pain, uses a larger dosage of medicine, and has a better treatment effect. Intramuscular injections are usually given in the buttocks, where the drug enters the capillaries. The drug is absorbed more slowly and the amount injected is relatively small. If your child has a cold or cough, let him drink plenty of water and rest indoors as much as possible to avoid catching a cold.

Absorption route: The drug is absorbed directly into the veins through the colon capillaries.

Clinical advantages: easy to absorb, painless, easy to operate, not prone to infection, especially suitable for children.

Clinical disadvantages: prone to cause colon irritation and relatively slow absorption.

Contraindications: Colon diseases such as chronic colitis, colon cancer.

Injection site

The most commonly used injection site for intramuscular injection is the gluteus maximus, followed by the gluteus medius, gluteus minimus, vastus lateralis and deltoid muscles. Precise positioning of the injection site is very important for intramuscular injection.

Gluteus maximus injection positioning: Cross method: draw a horizontal line from the apex of the gluteal cleft to the left or right, and make a vertical bisector from the highest point of the iliac crest downward to divide the buttocks into four quadrants, among which the upper outer quadrant avoiding the inner corner is the injection area. Line method: The outer third of the line from the anterior superior iliac spine to the coccyx is the injection site.

Gluteus medius and gluteus minimus injection positioning: There are fewer blood vessels and nerves in this area, and the fat tissue is thinner. It is now more widely used. There are two positioning methods:

Intramuscular injection

Intramuscular injection (20 photos):

a Place the tips of the index finger and middle finger on the anterior superior iliac spine and the lower edge of the iliac crest respectively, forming a triangular area between the iliac crest, index finger, and middle finger. The injection site is within the angle formed by the index and middle fingers.

b Three finger widths lateral to the anterior superior iliac spine. The width of the patient's finger should be used as the standard.

Vastus lateralis muscle injection location: The location is the outer side of the middle thigh: For adults, the range from 10 cm below the hip joint to 10 cm above the knee can be selected. There are few large blood vessels and nerve trunks passing through this area, and the area is wide, which can be used for multiple injections.

Injection location for the deltoid muscle of the upper arm: on the outer side of the upper arm, 2 to 3 horizontal fingers below the acromion. The muscles here are thinner than the buttocks muscles, so only small doses can be injected.
