What Happens If an intramuscular Injection Missed the Muscle?

Depending on the medication and dosage, intramuscular injections may also result in an abscess or gangrene at the injection site. Additionally, if a nerve or blood vessel is unintentionally struck while injecting, there is a chance of nerve or vascular injury.

Intramuscular Injections

Intramuscular injection is a parenteral medication administration technique that involves injecting medicine into a large muscle. Because the muscle is larger than the subcutaneous tissue, it absorbs medications more quicker. The injection site should be chosen carefully to avoid permanent damage and ensure proper medication absorption.

The deltoid muscle of the upper arm is a good site for an IM injection. It is the site most commonly used for vaccines. It is located just below the shoulder. However, the volume of medication administered to the deltoid muscle is limited.

The ventrolateral muscle near the hip is another good site for an IM injection. It possesses the largest muscle thickness. It is also free from blood vessels. Therefore, it is a good area for oily medications.

The dorsogluteal muscle of the buttock is also a good site for an IM injection. However, it is an awkward site to inject alone. It is a good site for injections if a caregiver is available. It is also a good site for self-administered IM injections. However, major blood vessels and nerves are a concern.

The rectus femoris in the lower leg is not a good site for an IM injection. Injections given to the rectus femoris can damage the descending branch of the LCFA. This can result in shoulder pain and arm pain. The descending branch of the LCFA is very vulnerable to damage from injections, and this risk can be avoided by taking an evidence-based approach.

When selecting an IM injection site, it is important to understand the anatomy of the muscle. In addition, the injection site should be located at an angle of 90 degrees to the skin. It is also important to wear gloves.

Injections that miss the Deltoid Muscle

Using the wrong injection site can lead to serious shoulder and arm pain. In addition, if you choose the wrong injection site, you can have a frozen shoulder, a limited range of motion, or even permanent loss of mobility.

The Centers for Disease Control (CDC) recommends administering adult vaccines to the arm’s deltoid muscle. However, there are alternative injection sites for adults.

The posterior deltoid muscle is another alternative injection site. This may be easier to administer and may increase the margin of error. However, this muscle does not have the same blood supply as the lateral deltoid muscle.

However, the lateral deltoid muscle is the most commonly used site for injections. In addition, the deltoid muscle is easily accessible and is a relatively avascular muscle. However, it has fewer nerves, so the risk of injury during the injection is lower.

Other possible sites for injection include the vastus lateralis muscle and the thigh muscle. The thigh muscle is the preferred injection site for infants and toddlers, but it is less suitable for injections for older children and adults. In addition, injections into the thigh muscle may cause temporary muscle pain, affecting the child’s ambulation.

Injections should be administered at 90 degrees to the skin, and the needle should not be inserted too high. If an injection is too high, the child may get soft tissue or tendons in the shoulder.

The thigh is also a common site for self-administered injections. This is because the muscle is large, and there are fewer major blood vessels. However, this location is not recommended for vaccines.

IM injections should not be given to the buttocks because of the shearing action of the needle and the potential for sciatic nerve injury. In addition, fat tissue is not a sound absorbent for vaccines, so the blood supply to this area is less.

Injections that miss the Rectus Femoris Muscle

Whether or not you are lucky enough to be able to get an IM injection, there are a few sites to avoid. The dorso gluteal region is home to the mighty gluteal muscle, but attempting to get a needle in your thigh may leave you scratching your head. The triceps has a similar problem.

The tensor femoris may be the only option if you are lucky enough to make the trip. This oblique muscle, which sits below the rectus femoris, is the most impressive of the gluteal muscles. As with the triceps, the tensor femoris is more complicated, but a smaller 22 to 25-gauge needle is likely to make the job easier. The gluteal muscle is the largest of the gluteal group and is home to the most significant single muscle group, the triceps.

The triceps is the most impressive of the three muscles. Despite being the king of the pack, it is a fairly clunky site to administer an IM injection. The triceps, like the triceps femoris, is a thigh muscle that is most prominent in the middle of the thigh and thigh. The triceps femoris is the largest of the three muscles and is arguably the most important muscle to administer an IM injection. The triceps femoris’s other notable attribute is its proximal triceps femoris.

There are numerous intramuscular injections available in some different formats, and the best route to take is to consult with a medical professional.

Injections that miss the Vastus Lateralis Muscle

The thigh muscle is one of the most commonly used for self-administered injections. This is a safe body part because it has fewer blood vessels and nerves. This makes it safe for injections.

The deltoid muscle is another good body part used for injections. It is recommended for adult injections and is used for multiple vaccines in older children. In children, however, the buttock muscle is not used because it can potentially injure the sciatic nerve.

The gluteal muscle can also be used for injections, but it is recommended only when anatomical landmarks are defined. This is because a thin layer of fat covers the muscle, and it is free from penetrating blood vessels.

Many injections are applied on the thigh, including the middle point of the rectus femoris, the iliac crest, and the gluteus medius and minimus. However, the literature suggests that the selection of these sites is inconsistent. It may be based on the confidence of the doctor, or it may be based on familiarity.

However, one study found that the thigh muscle may be a safe area for injections. It is also a preferred area for infants and children. The injection is less painful if a child is old enough to sit up. The iliac crest can also be used for an injection, but the V method is not reliable for people with a BMI over 3

Injections that miss the Dorsogluteal Muscle

The vastus lateralis muscle, located in the thigh, is a good choice. This muscle is the best for intramuscular injections due to its thickness. It is also free of penetrating blood vessels, making it the best choice for several reasons.

The gluteal muscle is also an option, but only if anatomic landmarks are clearly defined. Injections can also be administered in the ventrolateral muscle, which is located near the hip. The ventrolateral site is also a good choice for oily medications.

The vastus lateralis muscle is also the best for injections. However, the gluteal muscle should only be used in rare cases. It is not a great site for IM injections and should be avoided if muscle atrophy is a concern.

Another great site for injection is the iliac crest, the most prominent part of the hip. It should be avoided if there is an increased risk of infection, as IM injections may lead to localized infections.

The ventrolateral site is also able to handle multiple vaccines well. However, the thigh is the preferred site for infants and young children. Older children and adults may prefer the deltoid muscle, one of the best sites for multiple vaccines.

The best IM injection site depends on the type of medication, the recipient’s age and muscle development, and the size of the needle. It is also essential to choose the right needle to prevent infection. In addition, it is important to clean the site before administering the injection.


How do I know if I injected it into muscle?

At a 90-degree angle, insert the needle into the muscle. The syringe should be held steady by the index and thumb while the plunger is gently pulled back to check for blood with the other hand. If blood is present, the needle is most likely in a blood vessel rather than a muscle.

Which site is no longer recommended for intramuscular injections?

Select a location that is free from discomfort, infection, cuts, or necrosis. Due to the possibility of injury, the dorsogluteal site should be avoided for intramuscular injections. Inadvertently striking the sciatic nerve could result in temporary or permanent leg paralysis for the patient.

Do you still draw back on IM injections?

The World Health Organization and the Centers for Disease Control and Prevention no longer advise aspiration prior to intramuscular injection, despite the fact that it was a common practice until a few years ago.

Do you pinch during IM injection?

Stab the needle into the skin at a 45° angle. To avoid injecting into the muscle, pinch up on SQ tissue. Before injecting, aspiration is not necessary.
