intravenous (injected into the vein) subcutaneous (injected into the fatty tissue just under the layer of skin)
Why are drugs not given by an intra-arterial route?
Intra-arterial drug injection may cause vessel injury by one of several mechanisms. The vessel may be obstructed by inert particles or drug crystals. Hemolysis, platelet aggregation, vasospasm and venous thrombosis are the other contributory factors [2].
What is difference between IM and IV?
IV, or intravenous, injections are administered into the bloodstream either by a syringe or by a low pressure method known as a drip. The intramuscular shots are administered into the muscle, not the vein.
What is the intra-arterial route most commonly used for?
Intra-arterial (into an artery), e.g. vasodilator drugs in the treatment of vasospasm and thrombolytic drugs for treatment of embolism. Intra-articular, into a joint space. It is generally performed by joint injection. It is mainly used for symptomatic relief in osteoarthritis.
What are intravenous injections?
An intravenous (IV) injection is an injection of a medication or another substance into a vein and directly into the bloodstream. It is one of the fastest ways to get a drug into the body. IV administration involves a single injection followed by the insertion of a thin tube or catheter into a vein.
Can you give IV meds in an artery?
One of the most dreaded complications of this procedure is an inadvertent intra-arterial cannulation. This can result in an accidental injection of medications intra-arterially, which can potentially lead to life altering consequences.
Is IM better than IV?
Tveita et al compared patient safety and analgesic efficacy of a single high dose of morphine given intramuscularly or intravenously for postoperative pain management. The IV group experienced a significantly faster onset of analgesic effect than the IM group (5 minutes versus 20 minutes).
Which injection is better IV or IM?
IV drug administration achieves high plasma concentrations rapidly in plasma and tissues. Muscles are very vascular structures, and IM absorption occurs by drug diffusion from interstitial fluid and capillary membranes into plasma, and so onset of action is longer than IV injection.
When do we use intra-arterial injection?
Intraarterial administration of thrombolytic drugs allows lower systemic and higher local levels of the drug at the site of a thrombus. An initial case series reported on intraarterial administration of urokinase in five patients with an angiographically confirmed arterial occlusion [21].
