Injection site reactions (ISRs) are reactions that occur at the site of injection of a drug. They may be mild or severe and may or may not require medical intervention. Some reactions may appear immediately after injection, and some may be delayed. [1] Such reactions can occur with subcutaneous, intramuscular, or intravenous administration.
SIRVA is caused by improper insertion of the needle used in injections. It is "a preventable occurrence caused by the injection of a vaccine into the shoulder capsule rather than the deltoid muscle. As a result, inflammation of the shoulder structures causes patients to experience pain, a decreased range of motion, and a decreased quality of life."
[9]: 369 Intramuscular injections may also cause an abscess or gangrene at the injection site, depending on the specific medication and amount administered. There is also a risk of nerve or vascular injury if a nerve or blood vessel is inadvertently hit during injection.
Prepare the Injection. This will probably be the most time-consuming step, but it gets easier with practice and should take just a few minutes. Take the sterile cap off the GLP-1 medication and ...
In rare cases immunizations can cause serious adverse effects, such as gelatin measles-mumps-rubella vaccine (MMR) causing anaphylaxis, a severe allergic reaction. [13] Allegations particularly focus on disorders claimed to be caused by the MMR vaccine and thiomersal , a preservative used in vaccines routinely given to U.S. infants prior to 2001.
The preferred injection site is the crook of the elbow (i.e., the Median cubital vein), on the user's non-writing hand. Other users opt to use the Basilic vein; while it may be easier to "hit", caution must be exercised as two nerves run parallel to the vein, increasing the chance of nerve damage, as well as the chance of an arterial "nick". [5]
Adverse effects depend on the local anesthetic method and site of administration discussed in depth in the local anesthetic sub-article, but overall, adverse effects can be: localized prolonged anesthesia or paresthesia due to infection, hematoma, excessive fluid pressure in a confined cavity, and severing of nerves & support tissue during ...
