A subcutaneous injection is administered as a bolus into the subcutis, the layer of skin directly below the dermis and epidermis, collectively referred to as the cutis. Subcutaneous injections are highly effective in administering vaccines and medications such as insulin, morphine, diacetylmorphine and goserelin. Subcutaneous injection of recreational drugs is referred to as "skin popping." Subcutaneous administration may be abbreviated as SC, SQ, sub-cu, sub-Q, SubQ, or subcut. Subcut is the preferred abbreviation for patient safety.
Intramuscular injection is the injection of a substance directly into muscle. In medicine, it is one of several alternative methods for the administration of medications. Muscles have larger and more blood vessels than subcutaneous tissue and injections here usually have faster rates of absorption than subcutaneous injections or intradermal injections. Depending on the injection site, an administration is limited to between 2 and 5 milliliters of fluid.
Injection is the act of putting a liquid, especially a drug, into a person's body using a needle and a syringe. Injection is a technique for delivering drugs by parenteral administration, that is, administration via a route other than through the digestive tract. Parenteral injection includes subcutaneous, intramuscular, intravenous, intraperitoneal, intracardiac, intraarticular and intracavernous injection.
Panniculitis is a group of diseases whose hallmark is inflammation of subcutaneous adipose tissue. Symptoms include tender skin nodules, and systemic signs such as weight loss and fatigue.
A hematoma or haematoma is a localized bleeding outside of blood vessels, due to either disease or trauma including injury or surgery and may involve blood continuing to seep from broken capillaries. A hematoma is benign and is initially in liquid form spread among the tissues including in sacs between tissues where it may coagulate and solidify before blood is reabsorbed into blood vessels. An ecchymosis is a hematoma of the skin larger than 10mm.
A skin condition, also known as cutaneous condition, is any medical condition that affects the integumentary system—the organ system that encloses the body and includes skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment.
An ecchymosis is a subcutaneous spot of bleeding with diameter larger than 1 centimetre (0.39 in). It is similar to a hematoma, commonly called a bruise, though the terms are not interchangeable in careful usage. Specifically, bruises are caused by trauma whereas ecchymoses, which are the same as the spots of purpura except larger, are not necessarily caused by trauma, often being caused by pathophysiologic cell function, and some diseases such as Marburg virus disease.
The subcutaneous tissue, also called the hypodermis, hypoderm, subcutis, or superficial fascia, is the lowermost layer of the integumentary system in vertebrates. The types of cells found in the hypodermis are fibroblasts, adipose cells, and macrophages. The hypodermis is derived from the mesoderm, but unlike the dermis, it is not derived from the dermatome region of the mesoderm. In arthropods, the hypodermis is an epidermal layer of cells that secretes the chitinous cuticle. The term also refers to a layer of cells lying immediately below the epidermis of plants.
Allergen immunotherapy, also known as desensitization or hypo-sensitization, is a medical treatment for environmental allergies, such as insect bites, and asthma. Immunotherapy involves exposing people to larger and larger amounts of allergen in an attempt to change the immune system's response.
ICD-10 is an international statistical classification used in health care and related industries.
The intercrural fibers are a series of curved tendinous fibers, which arch across the lower part of the aponeurosis of the Obliquus externus, describing curves with the convexities downward.
Treprostinil (marketed under the trade names Remodulin for infusion, Orenitram for oral, and Tyvaso for inhalation) is a vasodilator that is used for the treatment of pulmonary arterial hypertension. Treprostinil is a synthetic analog of prostacyclin (PGI2).
Prodine is an opioid analgesic that is an analog of pethidine (meperidine). It was developed in Germany in the late 1940s.
The subcutaneous tissue of penis is continuous above with the fascia of Scarpa, and below with the dartos tunic of the scrotum and the fascia of Colles.
Subcutaneous emphysema is when gas or air is in the layer under the skin. Subcutaneous refers to the tissue beneath the skin, and emphysema refers to trapped air. Since the air generally comes from the chest cavity, subcutaneous emphysema usually occurs on the chest, neck and face, where it is able to travel from the chest cavity along the fascia. Subcutaneous emphysema has a characteristic crackling feel to the touch, a sensation that has been described as similar to touching Rice Krispies; this sensation of air under the skin is known as subcutaneous crepitation.
Bolandione, also known as 19-norandrostenedione, as well as 19-norandrost-4-en-3,17-dione or estr-4-ene-3,17-dione, is a precursor of the anabolic-androgenic steroid (AAS) nandrolone (19-nortestosterone). Until 2005, bolandione was available without prescription in United States, where it was marketed as a prohormone, but it is now classified as a Schedule III drug. It is also banned from use in many sports, including the Olympic Games, under the World Anti-Doping Code. Bolandione is readily metabolized to nandrolone after oral administration, but its potency to transactivate the androgen receptor dependent reporter gene expression is 10 times lower as compared to dihydrotestosterone (DHT).
Sclerema neonatorum is a rare and severe skin condition that is characterized by diffuse hardening of the subcutaneous tissue with minimal inflammation. It usually affects premature, ill newborns. Prognosis is poor.
Intradermal injection (ID) is s shallow or superficial injection of a substance into the dermis, in between the epidermis and the hypodermis. This route is relatively rare compared to subcutaneous injections (SC) and intramuscular injections (IM), and used only when certain therapies, like tuberculin and allergy tests, require the specific benefits of this route of administration and where easier to use SC and IM injections have no effect. Specific benefits are a higher immune responses for vaccinations, immunology and novel cancer treatments and faster drug uptake, since for certain small and well soluble proteins or molecules, ID route of administration is associated with fast uptake systemically compared to subcutaneous injections, applied in novel closed loop insuline infusion systems. Additionally, the body's reaction to substances is more easily visible since it is closer to the surface.
Immunoglobulin therapy, also known as normal human immunoglobulin (NHIG), is the use of a mixture of antibodies (immunoglobulins) to treat a number of health conditions. These conditions include primary immunodeficiency, idiopathic thrombocytopenic purpura, chronic inflammatory demyelinating polyneuropathy, Kawasaki disease, certain cases of HIV/AIDS and measles, Guillain-Barré syndrome, and in certain other infections when a more specific immunoglobulin is not available. Depending on the formulation it can be given by injection into muscle, a vein, or under the skin. The effects last a few weeks.
In medicine, a subcutaneous implant, or subcutaneous pellet, is an implant that is delivered under the skin into the subcutaneous tissue by surgery or injection and is used to deliver a drug for a long period of time. Examples of drugs that can be administered in this way include leuprorelin and the sex steroids estradiol and testosterone.
