Injection position of gluteus maximus: cross method: draw a horizontal line from the vertex of gluteal fissure to the left or right, and draw a vertical line from the vertex of iliac crest downward, and divide the gluteus into four quadrants, in which the outer upper quadrant avoids the inner corner as the injection area. Connection mode: the outer third of the connecting line from the anterior superior iliac spine to the coccyx is the injection site.
Injection site of gluteus medius and gluteus minimus: There are few blood vessels and nerves and thin adipose tissue in this area, which is widely used at present. There are two positioning methods:
A fingertip and middle fingertip are placed on the anterior superior iliac spine and the lower edge of iliac crest respectively, forming a triangular area between iliac crest, index finger and middle finger. The injection site is within the angle formed by the index finger and the middle finger.
B the third finger on the lateral side of the anterior superior iliac spine. A sick child should take the width of his finger as the standard.
Injection position of lateral femoral muscle: the position is in the middle and lateral thigh: below hip joint 10cm to above knee 10cm, which is desirable for ordinary adults. Great blood vessels and nerve trunks rarely pass through here, and the position is wide, so it can be injected multiple times.
Injection position of deltoid muscle of upper arm: lateral side of upper arm, 2~3 transverse fingers below acromion. The muscles here are thinner than those in the buttocks, and only small doses can be injected.
It is best to sit or lie down.
(1) Lying position: In order to relax local muscles and relieve pain and discomfort, the following postures can be adopted when injecting gluteal muscles:
Lateral position: the thighs are straight and relaxed, and the calves are slightly bent.
Prone position: the toes are opposite, the heels are drooping, and the head is tilted to one side.
Supine position: It is often used for critically ill patients and patients who can't turn over. It is more convenient to inject gluteus medius and gluteus minimus.
(2) Sitting position: it is a common position for outpatients to receive injections. For the deltoid muscle head of the upper arm, if the injected drug is oil or suspension, a thick needle is needed; Prepare the potion according to the doctor's advice.
