injection
injection, introduction of a fluid into the body, usually by means of a needle and syringe. The material injected may be a test substance (as in determining allergic sensitivity or immunity to a disease), an anesthetic, a therapeutic drug, a nutrient (in cases where intravenous feeding is necessary), blood, or blood plasma (see blood transfusionblood transfusion, transfer of blood from one person to another, or from one animal to another of the same species. Transfusions are performed to replace a substantial loss of blood and as supportive treatment in certain diseases and blood disorders. ..... Click the link for more information. ). An intracutaneous injection is the introduction of a small amount of fluid between the skin layers. A subcutaneous injection is directed to the tissues under the skin. When quicker absorption of a drug is required, an intramuscular injection may be used; even more rapid action is obtained by injection into a vein (intravenous). In certain emergencies involving the heart, such as cardiac arrest, an intracardiac injection can penetrate directly into a chamber of the musculature of the heart. Anesthetics are sometimes injected into the spine. In an injection by means of a jet injector gun, fluid penetrates through the skin by means of air pressure and there is no visible puncture mark. Micro-injections can be made into fetuses, even individual cells, with tiny capillary injectors.injection (insertion) The process of boosting a spacecraft into a particular orbit or trajectory. It is also the time of such action or the entry itself.Injection the introduction of small quantities of medicine in solution or emulsion into subcutaneous tissue, intramuscularly, or intravenously with syringe and needle. With injection a more rapid effect is achieved than with ingestion, as well as precise dosage and reliability of effect. With injection, medication may be introduced regardless of the condition of the patient, such as unconsciousness and inability to swallow. For localized effect medicinal solutions are injected into the pleural cavity or joints; intradermal injections are used for analgesia and for diagnostic purposes, for example, the Mantoux reaction for diagnosing tuberculosis. Intracardiac injection is resorted to when there is a sudden heart stoppage (injury from electric shock, gas poisoning, and narcosis). Injection into the cerebrospinal canal is done for analgesia and treatment of certain diseases. The rules of asepsis must be observed without fail in injection. What does it mean when you dream about an injection?In traditional psychoanalysis, a dream about an injection is often viewed as a dream about sexual intercourse. Can also indicate an influence that is forced on us. If we had bad experiences with being inoculated as children, then an injection dream can represent any number of different anxieties and fears. injection[in′jek·shən] (aerospace engineering) The process of placing a spacecraft into a specific trajectory, such as an earth orbit or an encounter trajectory to Mars. Also known as insertion. (electronics) The method of applying a signal to an electronic circuit or device. The process of introducing electrons or holes into a semiconductor so that their total number exceeds the number present at thermal equilibrium. (geology) Also known as intrusion; sedimentary injection. A process by which sedimentary material is forced under abnormal pressure into a preexisting rock or deposit. A structure formed by an injection process. (mathematics) A mapping ƒ from a set A into a set B which has the property that for any element b of B there is at most one element a of A for which ƒ(a) = b. Also known as injective mapping; one-to-one mapping; univalent function. (mechanical engineering) The introduction of fuel, fuel and air, fuel and oxidizer, water, or other substance into an engine induction system or combustion chamber. (medicine) Introduction of a fluid into the skin, vessels, muscle, subcutaneous tissue, or any cavity of the body. The substance injected. (mining engineering) The introduction under pressure of a liquid or plastic material into cracks, cavities, or pores in a rock formation. injection (mathematics)A function, f : A -> B, is injective orone-one, or is an injection, if and only if
for all a,b in A, f(a) = f(b) => a = b.
I.e. no two different inputs give the same output (contrastmany-to-one). This is sometimes called an embedding. Onlyinjective functions have left inverses f' where f'(f(x)) = x,since if f were not an injection, there would be elements of Bfor which the value of f' was not unique. If an injectivefunction is also a surjection then is it a bijection.injection (reduction)An injection function is one which takesobjects of type T and returns objects of type C(T) where C issome type constructor. An example is
f x = (x, 0).
The opposite of an injection function is a projectionfunction which extracts a component of a constructed object,e.g.
fst (x,y) = x.
We say that f injects its argument into the data type and fstprojects it out. See injectioninjection
injection [in-jek´shun] 1. congestion.2. the forcing of a liquid into a part, as into the subcutaneous tissues, the vascular tree, or an organ.3. a substance so forced or administered; in pharmacy, a solution of a medicament suitable for injection. Immunizing substances, or inoculations, are generally given by injection. Some medicines cannot be given by mouth because chemical action of the enzymes and digestive fluids would change or reduce their effectiveness, or because they would be removed from the body too quickly to have any effect. Occasionally a medication is injected so that it will act more quickly. In addition to the most common types of injections described below, injections are sometimes made into arteries, bone marrow, the spine, the sternum, the pleural space of the chest region, the peritoneal cavity, and joint spaces. In sudden heart failure, heart-stimulating drugs may be injected directly into the heart (intracardiac injection).Sites for injections. A, subcutaneous injection sites. B, intramuscular injection site for children in the vastus lateralis muscle. C, D, and E, intramuscular injection sites for adults: C, deltoid muscle injection site. D, injection site in the buttock (dorsogluteal site). E, injection site in the anterolateral thigh (ventrogluteal site).hypodermic injection subcutaneous injection.intracutaneous injection intradermal injection.intracytoplasmic sperm injection (ICSI) a micromanipulation technique used in male factor infertility; a single spermatocyte is inserted into an oocyte by micropuncture.intradermal injection injection of small amounts of material into the corium or substance of the skin, done in diagnostic procedures and in administration of regional anesthetics, as well as in treatment procedures. In certain allergy tests, the allergen is injected intracutaneously. These injections are given in an area where the skin and hair are sparse, usually on the inner part of the forearm. A 25-gauge needle, about 1 cm long, is usually used and is inserted at a 10- to 15-degree angle to the skin.intramuscular injection injection into the substance of a muscle, usually the muscle of the upper arm, thigh, or buttock. Intramuscular injections are given when the substance is to be absorbed quickly. They should be given with extreme care, especially in the buttock, because the sciatic nerve may be injured or a large blood vessel may be entered if the injection is not made correctly into the upper, outer quadrant of the buttock. The deltoid muscle at the shoulder is also used, but less commonly than the gluteus muscle of the buttock; care must be taken to insert the needle in the center, 2 cm below the acromion. Injections into the anterolateral aspect of the thigh are considered the safest because there is less danger of damage to a major blood vessel or nerve. The area permits multiple injections, is more accessible, and is easier to stabilize, particularly in pediatric patients or others who are restless and uncooperative. The vastus lateralis muscle is located by identifying the trochanter and the side of the knee cap and then drawing a visual line between the two. The distance is then divided into thirds and the needle inserted into the area identified as the middle third. The needle should be long enough to insure that the medication is injected deep into the muscle tissue. The gauge of the needle depends on the viscosity of the fluid being injected. As a general rule, not more than 5 ml is given in an intramuscular injection for an adult. The maximum for an infant is 0.5 ml, and the injection is made into the vastus lateralis muscle. The needle is inserted at a 90-degree angle to the skin. When the gluteus maximus muscle is the site chosen for the injection, the patient should be in a prone position with the toes turned in if possible. This position relaxes the muscle and makes the injection less painful.intrathecal injection injection of a substance through the theca of the spinal cord into the subarachnoid space. Patients receiving intrathecal chemotherapy for metastatic malignancy of the central nervous system should maintain a flat or Trendelenburg position for one hour after treatment to achieve optimum distribution of the drug.intravenous injection an injection made into a vein. Intravenous injections are used when rapid absorption is called for, when fluid cannot be taken by mouth, or when the substance to be administered is too irritating to be injected into the skin or muscles. In certain diagnostic tests and x-ray examinations a drug or dye may be administered intravenously. (See also intravenous infusion.)jet injection injection of a drug in solution through the intact skin by an extremely fine jet of the solution under high pressure.subcutaneous injection injection made into the subcutaneous tissues. Although usually fluid medications are injected, occasionally solid materials such as steroid hormones may be injected in small, slowly absorbed pellets to prolong their effect. Subcutaneous injections may be given wherever there is subcutaneous tissue, usually in the upper outer arm or thigh. A 25-gauge needle about 2 cm long is usually used, held at a 45-degree angle to the skin, and the amount injected should not exceed 2 ml in an adult. Subcutaneous insulin injections may be given at a 90-degree angle with an insulin syringe. Called also hypodermic injection.Angle of needle insertion for administering a subcutaneous injection. From Lammon et al., 1995.Z-track injection see z-track injection.in·jec·tion (in-jek'shŭn), 1. Introduction of a medicinal substance or nutrient material into subcutaneous tissue (that is, subcutaneous or hypodermic injection), muscular tissue (that is, intramuscular injection), a vein (that is, intravenous injection), an artery (that is, intraarterial injection), the rectum (that is, rectal injection or enema), the vagina (that is, vaginal injection or douche), the urethra, or other canals or cavities of the body. 2.

The forcing of a fluid into a vessel, tissue, or cavity. Patient careAll supplies used in preparing and administering an injection should be sterile. The caregiver chooses the appropriate syringe size for the volume of fluid to be injected, the appropriate needle gauge for the type of fluid, and the appropriate needle length for the administration route and site, considering the amount of muscle and adipose tissue, mobility limitations, and other site-related factors. Hands should be thoroughly cleansed before and after the procedure, and gloves worn if preparing a chemotherapeutic agent. The prescribed dose is accurately measured. An appropriate site is identified by using anatomical landmarks, and the area is cleansed with an antiseptic swab (from the center outward) and time allowed for the antiseptic to evaporate. The needle is inserted at the appropriate angle, given the prescribed route. Intradermal injections use a short fine needle with the opening faced upward; the needle is placed nearly parallel to the surface of the skin and advanced far enough for the injected fluid to make a small bubble under the skin, then carefully removed; pressure that could cause the fluid to leak out onto the skin surface should be avoided. Subcutaneous injections should consist of no more than 1 ml. A short needle should be inserted at a 45° angle, without aspiration, and gentle pressure or no pressure applied to the site after needle removal. After insertion into muscle (the needle is inserted directed into the muscle, at a 90° angle), the syringe plunger is aspirated to ensure that no blood returns to prevent accidental injection into a blood vessel. The prescribed medication is injected slowly, then the needle is removed, and pressure is applied to the site with a dry sponge. A Z-track method helps to ensure that the medication remains in the muscle as desired and does not leak back into subcutaneous tissues. When administering an intravenous (IV) injection, the syringe is aspirated and blood obtained to be certain the needle is in the vein. When removing a needle after administering an IV injection directly into the vein, the caregiver lessens the chance of bleeding into soft tissue by applying firm pressure with a dry sponge while elevating the site above the heart for several minutes. However, the vast majority of intravenous injections are administered through an IV catheter or an IV fluid port with a needle or needleless device. Pressure is not applied when removing this device. The needle should not be recapped; both the needle and syringe should be disposed in a “sharps” container according to protocol. The injection time and site, any untoward responses to the injection, desired effects, and adverse reactions to the particular drug injected are recorded. 2. A solution introduced in this manner.3. The state of being injected; congestion. depot injectionParenteral administration of a long-acting medication or hormone.dextrose and sodium chloride injectionA sterile solution of dextrose, salt, and water for use intravenously. It contains no antimicrobial agents. epidural injectionThe injection of anesthetic solution or other medicines into the epidural space of the spinal cord.fractional injectionInjection of small amounts at a time until the total injection is complete.hypodermic injectionAn obsolete term originally meaning the injection of a substance beneath the skin. It is preferable to specify the route of administration, e.g., intramuscular, subcutaneous, intracutaneous, or intravenous. See: local anesthesiaintra-alveolar injectionIntroduction of anesthetic into the soft tissues adjacent to a tooth.intracardial injectionInjection into the heart.intracytoplasmic sperm injection Abbreviation: ICSI A commonly used assisted reproduction technique, in which spermatozoa, usually from a man with obstructive azoospermia or a low sperm count, are introduced directly into the ova of his partner. Some oocytes become fertilized and can then be transferred to the woman's uterus, where they mature.intradermal injectionInjection into the skin, used in giving serums and vaccines when a local reaction is desired. See: Intradermal Injections: Locating Sites and Administering intralingual injectionThe injection of medicines into the tongue, usually done as an emergency measure when a vein suitable for use is not available because of circulatory collapse.intramuscular injectionInjection into intramuscular tissue, usually the anterior thigh, deltoid, or buttocks. Intramuscular injections are used primarily in the administration of vaccines, immune globulins, long-acting corticosteroids, some antibiotics, some hormones, analgesics, and sedatives. In shock, medications given intramuscularly may not be rapidly absorbed. No more than 4 ml should be injected at one time into an adult with normal musculature; in children and adults with underdeveloped musculature, no more than 2 ml should be injected at one time. Patients should be advised that intramuscular injections, e.g., for vaccination, are painful. CAUTION!To avoid injury, newborn intramuscular injections should be administered in the middle third of the vastus lateralis muscle using a 5/8-in, 25-gauge needle. intraosseous injectionIntraosseous infusion.intraperitoneal injectionInjection into the peritoneal cavity. intravenous injectionThe injection into a vein or, more commonly, into an intravenous catheter of drugs, electrolytes, or fluids. The insertion of a needle directly into a vein (rarely necessary) requires a degree of skill that is easily obtained if proper instruction is obtained. The vein may be distended by applying a tourniquet with sufficient pressure to stop venous return but not arterial flow. The tourniquet is applied several inches above the injection site. If the patient does not have vascular collapse, the arterial pulse can be palpated; if not, the tourniquet is too tight. Heat applied to the area for 15 min before starting the injection will also help distend the vessels. The use of a needle attached to a 5- or 10-ml syringe will greatly facilitate controlling the course of the needle. It is best to insert the needle into the vein with the bevel side facing out and then, after the needle is in the vein, to rotate it so that the bevel is face in. There will be resistance as the needle goes through one side of the vein wall. The vein should be entered with the needle making only a narrow angle with the long axis of the vein. This will help to prevent pushing the needle completely through the vein. cutdown; intraosseous infusion; SolutionsMany liquid preparations are given by intravenous infusion. Those commonly used include isotonic saline, Ringer's lactate, dextrose 5% in sterile water, hyperalimentation fluids, lipids, vitamins, and numerous medications. The solution may be given continuously or by intermittent or bolus injection. The rate of infusion varies with the patient's needs. SiteIntravenous infusion usually is given through a vein in the hand or arm, but central veins or other peripheral veins may be used as indicated. NoteIn patients with collapsed veins, it may be possible to make the veins apparent by placing a tourniquet around the arm or leg and then inserting a 23- or 25-gauge catheter into a tiny superficial vein. Instillation of sterile intravenous fluid into the vein while the catheter is in place will distend the entire larger vein proximal to the small vein. A larger needle or catheter can then be inserted into the larger vein. iodinated I 131 albumin injectionA standardized preparation of albumin iodinated with the use of radioactive iodine, 131I.iodipamide meglumine injectionA radiographic contrast medium combination of iodipamide and meglumine used to aid in x-ray examination of the gallbladder. iodohippurate sodium I 131 injectionA radioactive contrast medium used in testing renal function.iothalamate meglumine injectionA radiopaque contrast medium used in investigating arteries of the brain as well as in the rest of the body, and in studying kidney function.iron dextran injectionA preparation of iron suitable for parenteral use. CAUTION!Because of the risk of anaphylaxis, a test dose should be given before starting an infusion of iron. jet injectionThe injection of medicines and vaccines through the skin or intramuscularly without a needle. A nozzle ejects a fine spray of liquid at such speed as to penetrate but not harm the skin. The procedure is harmless and is esp. useful in immunizing a great number of persons quickly and economically. lethal injectionA method of capital punishment by a combination of medications, typically, a sedative, a paralytic agent, an analgesic agent, and a fatal dose of potassium. Unlike other forms of execution (such as electrocution or the gas chamber), lethal injection is the only method that relies upon the direct participation of health care professionals. Some professional organizations (such as the American Medical Association) and several state boards with oversight over health care practic, have questioned whether the participation of health care professionals in lethal injection is appropriate, legal, or moral. parathyroid injectionA standard preparation of the water-soluble parathyroid hormone. It increases the calcium content of the blood. posterior pituitary injectionA standard preparation of the polypeptide hormones obtained from the posterior lobe of the pituitary body of healthy domestic animals.protein hydrolysate injectionA sterile solution of amino acids and short-chain peptides. They represent the approximate nutritive equivalent of casein, lactalbumin, plasma, fibrin, or other suitable proteins from which the hydrolysate is derived by acid, enzymatic, or other method of hydrolysis. It may contain dextrose or other carbohydrates suitable for intravenous infusion. It is used intravenously in the treatment of hypoproteinemia in patients who are unable to eat or absorb food. rectal injectionAn instillation (not an injection) into the rectum; an enema.sclerosing injectionThe injection into a vessel or into a tissue of a substance that will bring about obliteration of the vessel or hardening of the tissues used, e.g., to manage esophageal varices or malignant pleural effusions.selenomethionine Se 75 injectionRadioactive l-selenomethionine in which the sulfur atom in the methionine has been replaced by selenium. The compound is used intravenously to investigate methionine metabolism. spinal injectionIntroduction of fluids or medications into the spinal canal, i.e., the intrathecal space.SUBCUTANEOUS INJECTIONsubcutaneous injectionInjection beneath the skin. Typical sites include the abdomen, upper or outer arm, and the thigh. See: illustrationvaginal injectionA rare term for the instillation of fluid into the introitus; a douche.vasopressin injectionA sterile solution of antidiuretic hormone. Z-TRACK INJECTIONZ-track injectionAn injection technique in which the surface (skin and subcutaneous) tissues are pulled and held to one side before the needle is inserted deep into the muscle tissue in the identified site. The medication is injected slowly, followed by a 10-sec delay, at which time the needle is removed and the tissues are quickly permitted to resume their normal position. This provides a Z-shaped track, which makes it difficult for the injected drug to seep back into subcutaneous tissues. See: illustrationinjection The introduction of any substance, especially medication or nutritional substances, into the body, usually by means of a hollow needle and a syringe. Injections may be given into the skin (intradermally), under the skin (subcutaneously), into a muscle (intramuscularly), into a vein (intravenously), into an artery (intra-arterially), into the SUBARACHNOID SPACE or into a sheath (intrathecally), or into an organ. The term is also sometimes used to refer to the introduction of substances into a body orifice such as the URETHRA, the vagina or the rectum.InjectionForcing a fluid into the body by means of a needle and syringe.Mentioned in: Transfusioninjection1. A state of visible hyperaemia due to dilatation and engorgement of the small blood vessels. 2. The act of introducing a drug into the body. ciliary injection Redness (almost lilac) around the limbus of the eye caused by dilatation of the deeper small blood vessels located around the cornea. It occurs in inflammation of the cornea, iris and ciliary body, and in angle-closure glaucoma. Each of these conditions is associated with loss of vision and usually pain. Syn. ciliary flush. See ocular decongestant; red eye; pericorneal plexus. conjunctival injection Redness (bright red or pink) of the conjunctiva fading towards the limbus due to dilatation of the superficial conjunctival blood vessels occurring in conjunctival inflammations. There is no loss of vision but ocular discomfort and no pain. See ocular decongestant; red eye; thyroid ophthalmopathy; pericorneal plexus. intravitreal injection Injection into the eye posterior to the limbus and directed towards the vitreous. It may be used to administer medication, corticosteroids (e.g. triamcinolone), an antiviral agent (e.g. ganciclovir) in extremely severe ocular inflammations, usually of a purulent nature, to inject antibiotics (e.g. amikacin, ceftazidime, vancomycin) immediately after vitrectomy, or to inject anti-VEGF drugs in the treatment of wet age-related macular degeneration. peribulbar injection Injection of a local anaesthetic (e.g. bupivacaine, lidocaine, procaine) around the globe (either single or multiple injections) to produce anaesthesia of the globe and periocular tissues, as well as paralysis of the extraocular muscles. Peribulbar injection may also be used to administer medication (e.g. corticosteroids) in posterior segment inflammation. Syn. peribulbar block. retrobulbar injection Injection of a local anaesthetic into the muscle cone behind the eye to produce anaesthesia of the globe and periocular tissues, as well as paralysis of the extraocular muscles. It is used less commonly than peribulbar block. Syn. retrobulbar block. subconjunctival injection A method of administering medication (e.g. antibiotics, corticosteroids, mydriatics) postoperatively, or in acute anterior segment inflammations. An area of conjunctiva away from the limbus is lifted to form a bleb and an injection is made into it. sub-Tenon's injection Injection of a local anaesthetic near or beyond the equator using a cannula, which has been inserted under the conjunctiva and Tenon's capsule a few mm from the limbus and slid posteriorly to produce anaesthesia of the globe as well as paralysis of the extraocular muscles. A sub-Tenon's injection may also be used to administer medication (e.g. corticosteroids) in posterior segment inflammation.in·jec·tion (in-jek'shŭn) 1. Introduction of a medicinal substance or nutrient material into subcutaneous tissue, muscular tissue, a vein, an artery, the rectum, or the other canals or cavities of the body. 2. An injectable pharmaceutical preparation. [L. injectio, a throwing in, fr. in-jicio, to throw in]Patient discussion about injectionQ. Why is insulin injected and not taken as a pill? A. so if that's the case, why can't you use a patch (like a nicotine patch)? wouldn't that do the same trick? Q. I received a corticosteroid injection in my left knne th A.M. Knee is all stiff & swollen. Is this normal? A. actually you might have already had an arthritis in your knee before, then your doctor injected you with a corticosteroid into the affected joint. usually you will feel better (less pain) in your affected joint. if the symptoms don't improve then I suggest you to go see your specialist for further advise and treatment. Q. My arm became limp after flu shot & have had pain in arm. Vaccine itself or improper injection? Any advice? I could not move my arm about 3 hours after the injection. It took about 3 days before I could raise my arm at all. It became painful to use and has bothered me for a couple of months. The doctor gave me a cortisone shot which helped some but not completely. He had never seen this reaction before. Is it a reaction to the vaccine or could it be the way it was injected? Is their anyone who has had or knows of a similar case?A. I had a flu shot last October, and it was given to me directly on the backside (and up high) of my shoulder. I went to the gym after I received the shot, and now have two tears in my (torn) rotator cuff, with a perforation in my rotator cuff tendon. I think it may have been improperly given. Now I need to have surgery to repair it. Look up your symptoms on webmd, and surf the net. Talk to your doctor too. The only way to find out what is really going on with it is to have an MRI. A simple xray will not reveal a tear in the muscle or tendon in the rotator cuff. If you can't lift your arm, and have trouble sleeping at night, and pain on your deltoid and bicep (rotator cuff injury pain radiates to these areas) because of the pain, then chances are you have an injured rotator cuff. These people giving these immunizations need more training. They are causing serious injury to people that go in to get a shot to stay healthy, and then end up with a serious injury, and possible surgery !!!
