What happens when you get an intramuscular injection?

What happens when you get an intramuscular injection?

Intramuscular injections commonly result in pain, redness, and swelling or inflammation around the injection site. These side effects are generally mild and last no more than a few days at most. Rarely, nerves or blood vessels around the injection site can be damaged, resulting in severe pain or paralysis.

What are the advantages of intramuscular injections?

Advantages

• Rapid and uniform absorption of the drug, especially those of the aqueous solutions.
• Rapid onset of the action compared to that of the oral and the subcutaneous routes.
• IM injection bypasses the first-pass metabolism.
• It also avoids the gastric factors governing the drug absorption.

How long does it take for an intramuscular injection to take effect?

Intramuscular administration relies upon the high vascularity of muscle tissue to achieve a moderately rapid onset of action, usually within 5 to 10 minutes. When properly administered, intramuscular injection provides a more rapid onset and offset as compared with enteral techniques (see Fig.

Do intramuscular injections enter the bloodstream?

An intramuscular injection is a technique used to deliver a medication deep into the muscles. This allows the medication to be absorbed into the bloodstream quickly.

What happens if testosterone is injected into the bloodstream?

Testosterone can raise your blood pressure, which could increase your risk of heart attack, stroke, or death. Your blood pressure will need to be checked often. You may need to stop using testosterone or start taking blood pressure medication. You will need frequent blood tests.

What muscles do you give intramuscular injections?

Intramuscular injections are often given in the following areas:

• Deltoid muscle of the arm. The deltoid muscle is the site most typically used for vaccines.
• Vastus lateralis muscle of the thigh.
• Ventrogluteal muscle of the hip.
• Dorsogluteal muscles of the buttocks.

What happens if needle hits sciatic nerve?

Damage to the sciatic nerve can produce effects ranging from minor motor and sensory abnormalities to complete paralysis and causalgia, an excruciating and incapacitating pain that is resistant to analgesic treatment.

What are complications of intramuscular injections?

What are the complications of intramuscular injections?

• severe pain at the injection site.
• tingling or numbness.
• redness, swelling, or warmth at the injection site.
• drainage at the injection site.
• prolonged bleeding.
• signs of an allergic reaction, such as difficulty breathing or facial swelling.

What is an intramuscular injection?

In an intramuscular injection the needle is passed deeply into the substance of a muscle before the fluid is injected. Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005 in·tra·mus·cu·lar

What is intramuscular and intermuscular coordination?

Intra- and Intermuscular Coordination Intramuscular coordination is the firing pattern of fibers within an individual muscle. For example, prior to a ballistic action, there appears to be a silent period in electrical activity at the local muscle.

What muscles are used in intramuscular steroid injections?

In infants, the vastus lateralis muscle of the thigh is commonly used. The injection site must be cleaned before administering the injection, and the injection is then administered in a fast, darting motion to decrease the discomfort to the individual.

What is the purpose of intramuscular route of administration?

The intramuscular route is used where effects are desired over a longer period of time than can be expected after intravenous injection, for drugs that are too irritant to be given subcutaneously, or for oily solutions, which cannot be given intravenously. Drugs in aqueous solution are often absorbed rapidly from intramuscular sites.
