What Are the Different Types of Intramuscular Injection Needles?

Intramuscular injection is a commonly used drug injection treatment method, which refers to injecting a medicinal solution into a muscle tissue through a syringe to achieve the purpose of curing a disease.

Intramuscular injection is a commonly used drug injection treatment method, which refers to injecting a medicinal solution into a muscle tissue through a syringe to achieve the purpose of curing a disease.

Intramuscular injection is mainly applicable to: when intravenous injection is not suitable or cannot be performed, and a curative effect is required to occur more quickly than subcutaneous injection, and when a drug with a strong irritation or a large dose is injected.

Purpose

Usually for healing

Injection location

Gluteus maximus, middle gluteus, gluteus minor, etc.

Intramuscular injection site

The most commonly used part of intramuscular injection is the gluteus maximus, followed by the gluteus glutes, gluteus minor, lateral femoris, and deltoid muscle. Intramuscular injection is important for precise positioning of the injection part.

Gluteus maximus injection positioning: Cross method: Draw a horizontal line to the left or right from the apex of the gluteal, make a vertical bisector from the highest point of the hip, divide the hip into four quadrants, and the upper upper quadrant avoids the inner angle for injection Area. Wiring method: The outer third from the anterior superior iliac spine to the coccyx is the injection site.

Gluteus medius and gluteus minor injection positioning: There are fewer blood vessels and nerves distributed here, and the fat tissue is thin. At present, it is widely used. There are two positioning methods.

Species:

a Put the tip of forefinger and middle finger on the superior spine of the iliac bone and the lower edge of the iliac crest respectively, and form a triangle area between the iliac crest, index finger, and middle finger. The injection site is in the corner formed by the index and middle fingers.

b Three lateral fingers of the lateral superior anterior superior spine. Sick children should be based on the width of their fingers.

Positioning of lateral femoral muscle injection: The position is outside the middle of the thigh: Generally, adults can take a range from 10cm below the hip joint to 10cm above the knee, where large blood vessels and nerve trunks rarely pass, and the site is wide, which can be used for multiple injections.

Upper arm deltoid muscle injection positioning: outside the upper arm, 2 to 3 below the acromion and at the horizontal fingers. Here the muscles are thinner than the hip muscles and can only be injected in small doses.

Preferable sitting or lying position.

(1) Lying position: In order to relax local muscles and reduce pain and discomfort during intramuscular injection of the buttocks, the following postures may be adopted:

Side lying position: Straighten your upper legs, relax, and slightly bend your lower legs.

Prone position: The toes are opposite, the heels are drooping, and the head is sideways.

Supine position: It is commonly used in critically ill patients and patients who cannot turn over. It is more convenient to use the gluteal muscle and gluteal muscle injection method.

(2) Sitting position: commonly used position when receiving injection for outpatients. It can be used for the deltoid muscle head of the upper arm. If the injection is oil or suspension, a thicker needle is required; prepare the liquid as prescribed by your doctor.

Intramuscular injection procedure

(1) Prepare a bedside table, check with the patient, and explain to the patient for cooperation.

(2) Help the patient to take proper position, disinfect the skin with 2% iodine wine and 70% ethanol or 3% complexed iodine alone, and wait to dry.

(3) Exhaust the air in the syringe from which the drug is drawn.

(4) Separate the skin with your left thumb and forefinger, and hold the needle with your right hand, such as holding a pen, and fix the needle plug with your middle finger. The needle and injection site are mp, and penetrate into the muscle quickly. Generally, the needle is about 2.5 ~ 3cm (2/3 of the needle, thinner and sick children should be reduced).

(5) Loosen the left hand and twitch the piston. If there is no blood return, fix the needle and inject the medicine. After the injection, press the needle with a dry cotton swab, and quickly pull the needle.

(6) Help the patient lie in a comfortable position. Cleaning supplies.

The following issues should be noted in intramuscular injections:

(1) It is necessary to inject two kinds of medicine at the same time, and it is necessary to pay attention to incompatibility.

(2) Do not inject the drug until the blood is drawn back.

(3) The injection site is suitable for the individual. Gluteus maximus injection should not be used for infants under 2 years of age, but should be used for gluteus maximus and gluteal muscle injection. Because young children's gluteal muscles are generally poorly developed before they can walk alone, gluteal muscle injection may injure the sciatic nerve.

(4) Accurate positioning, especially gluteal muscle injection should avoid sciatic nerve injury.

(5) Do not pierce the needle fully to prevent the needle from breaking off from the joint. Once the needle is broken, keep the part and limbs still, quickly grasp the broken end with blood vessel forceps and pull out. If the stump all enters the muscle, it is removed surgically.

(6) For patients who need long-term intramuscular injection, the injection site should be changed frequently to prevent local induration. If induration occurs, hot water bag or hot wet compress, physical therapy can be taken.

Intramuscular child care

Intramuscular injection is a commonly used method of administration in children with illness. It is usually used when the drug should not be taken orally, the sick child cannot take the drug or when the rapid effect of the drug is required according to the condition. In general, although intramuscular injection is performed by a nurse, as a parent, it should also assist in good nursing work.

(1) For sensible children, explain the need for injections and let them bravely accept them. In particular, give them sympathy and comfort, eliminate tension and fear, and reduce adverse reactions.

(2) Assist the nurse to do the three checks and three pairs before the injection, and be accurate.

(3) If the drug requires an allergy test before use, parents should closely observe the child for abnormalities or discomfort. If there is no chest tightness, shortness of breath, poor breathing, pale, bruising or irritability, in order to report to the medical staff in a timely manner, take appropriate measures immediately.

(4) During the intramuscular injection, the infants and young children should be fixed well so as not to be struggling and disturbed, so as not to break the needle.

(5) Do not leave immediately after injection, stay in the hospital and observe for about 15 minutes.

(6) Allow the child to rest for a while after intramuscular injection. After intramuscular injection, if the child complains of pain at the injection site and inconvenient walking, observe closely. Go to the hospital and ask a doctor to check if necessary.

(7) Local lumps caused by drugs after intramuscular injection can be absorbed by hot compresses or moxa sticks.

Intramuscular route of transmission

After the drug is dissolved in the interstitial fluid, it enters the capillary network and then into the vein or directly into the small vein or into the lymph fluid and then into the large vein. The venous blood enters the right atrium and then into the right ventricle. After pulmonary circulation, it returns to the left atrium. The left ventricle enters the systemic circulation, reaches the liver, metabolizes active ingredients, and then reaches the whole body or lesion with blood flow. If it is active without metabolism, it can go directly to the whole body without entering the liver.
