In children under 2 years of age, the intramuscular injection site is

For children under 2 years old who need an intramuscular injection, it is best to choose a suitable site and try not to inject in areas where blood vessels are sparsely distributed, as this will make the injection very difficult. At this time, try to choose to inject the muscles on the hand, which is also the easiest site for intramuscular injection and will not cause too much pain to the baby.

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

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 those in the buttocks, so only small doses can be injected.

You can sit or lie down.

(1) Lying position: During intramuscular injection in the buttocks, the following positions can be adopted to relax the local muscles and relieve pain and discomfort:

Side-lying position: upper leg straight and relaxed, lower leg slightly bent.

Prone position: toes facing each other, heels hanging apart, head tilted to one side.

Supine position: often used for critically ill patients and patients who cannot turn over. It is more convenient to use the gluteus medius and gluteus minimus muscle injection method.

(2) Sitting position: This is the position commonly used by outpatients when receiving injections. It can be used for the deltoid head of the upper arm. If the injectable medication is an oil or suspension, a thicker needle is required; prepare the liquid medicine according to the doctor's instructions.

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.

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.
