What happens if injection goes into subcutaneous?

Injecting a vaccine into the layer of subcutaneous fat, where poor vascularity may result in slow mobilisation and processing of antigen, is a cause of vaccine failure1—for example in hepatitis B,2 rabies, and influenza vaccines.

Which substance is injected into subcutaneous tissue?

Subcutaneous injection means “under the skin,” and is a method used in clinical settings to inject insulin, Morphine, diacetylmorphine, and goserelin. Heroin, other opioids, cocaine, methamphetamine, amphetamine, and various other medications can all be abused by subcutaneous injection.

Why are injections given in the subcutaneous layer?

Subcutaneous injection can be used to give many types of medications for various medical conditions. There are fewer blood vessels in the fatty layer of connective tissue just beneath the skin than the muscle tissue. Having fewer blood vessels means that medication injected subcutaneously is absorbed more slowly.

How deep should a subcutaneous injection be?

You may give an injection within the following area: below the waist to just above the hip bone and from the side to about 2 inches from the belly button. Avoid the belly button.

Why subcutaneous injection is the slowest?

As subcutaneous tissue has few blood vessels, the injected drug is diffused very slowly at a sustained rate of absorption. Therefore, it is highly effective in administering vaccines, growth hormones, and insulin, which require continuous delivery at a low dose rate.

What are the risk of subcutaneous injection?

4 Potential Complications of Self-Administered Subcutaneous Injection

• 1.) Pain. The thought of injection is already painful—from blood checkups to surgeries.
• 2.) Bruising and Other Skin Irritations. Bruising is said to happen from time to time.
• 3.) Skin Infection.
• 4.) Tool Glitches.

Do you massage after a subcutaneous injection?

Don’t aspirate after inserting the needle (to prevent tissue damage, hematoma formation, and bruising). The likelihood of injecting into a blood vessel is small. Don’t massage the site, which can damage the underlying tissue and cause the medication to be absorbed faster than intended.

Why wouldn’t you use the same position on the body for a subcutaneous injection repeatedly?

Using the same injection site over and over again can cause discomfort and even tissue damage. As with any injection procedure, infection at the site of injection is a possibility. Signs of infection at the injection site include: severe pain.
