  1. Injection

  2. Injection is a method of putting liquid into the body with a hollow needle and a syringe which is pierced through the skin to a sufficient depth for the material to be forced into the body.

  3. An injection follows a parenteral route of administration, that is, its effect is not necessarily local to the area in which the injection is administered; it is systemic.

  4. There are several types of injections including:Intradermal:IDSubcutaneous:SCIntramuscular:IM intravenous:IV

  5. Some injection method else:intra-arterial (into an artery), e.g. vasodilator drugs in the treatment of vasospasm and thrombolytic drugs for treatment of embolism. Intracardiac (into the heart), e.g. adrenaline during cardiopulmonary resuscitation Intraosseous infusion (into the bone intravenous access because the bone marrow drains directly into the venous system. This route is occasionally used for drugs and fluids in emergency medicine and paediatrics when intravenous access is difficult.Intrathecal (into the spinal canal) is most commonly used for spinal anesthesia and chemotherapyIntraperitoneal, (infusion or injection into the peritoneum) e.g. peritoneal dialysis is predominantly used in veterinary medicine and animal testing for the administration of systemic drugs and fluids due to the ease of administration compared with other parenteral methods
