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."
Intramuscular injection, often abbreviated IM, is the injection of a substance into a muscle. In medicine , it is one of several methods for parenteral administration of medications. Intramuscular injection may be preferred because muscles have larger and more numerous blood vessels than subcutaneous tissue, leading to faster absorption than ...
It may lead to damage of soft tissue and other organs. The trigger points in the upper quadratus lumborum, for instance, are very close to the kidneys and poorly administered treatment (particularly injections) may lead to kidney damage. Likewise, treating the masseter muscle may damage the salivary glands superficial to this muscle.
Injection fibrosis is a complication of intramuscular injection, occurring especially often in infants and children. Injections are often delivered to the quadriceps, triceps, and gluteal muscles, and thus the complication often manifests itself in those muscles. Patients are unable to fully flex the affected muscle. The condition is painless ...
Among possible clinical complications are infection at the injection site, inflammation and pain at the injection or catheter site, bleeding or bruising from injury of small blood vessels, nerve injury, allergic reaction from a local anesthetic or neurolytic medication, or tinnitus and flushing from an agent like phenol.
A common side effect is soreness near the site of injection. Fever occurs in five to ten percent of children vaccinated, and temporary muscle pains or feelings of tiredness may occur. In certain years, the vaccine was linked to an increase in Guillain–Barré syndrome among older people at a rate of about one case per million doses. [ 30 ]
Needle insertion angles for 4 types of injection: intramuscular, subcutaneous, intravenous, and intradermal Injections are classified in multiple ways, including the type of tissue being injected into, the location in the body the injection is designed to produce effects, and the duration of the effects.
