Intravenous treatment is defined as a parenteral administration of a drug through intravenously, that is, into a vein by means of intravenous injection (IV) for therapeutic purpose. Intravenous injection has given to the patient for the treatment of a disease rapidly because the route of administration of any drug or fluid through intravenously is very quickly effective and take action against disease within a short period of time. Intravenous treatment suggested in emergency treatment. This includes emergencies like heart attack. Poisoning. The parenteral route of drug through intravenously effects within a few second. A drug or any fluid minerals given through intravenously are in dissolved because drug can easily enter through the vein and reaches to the targeted site. The bloodstream carries drug and act to the targeted site. Intravenous treatments is used for rapid reaction through parenteral route drug cannot enter into the long process of absorption and metabolism of a drug in order to save time doctors used intravenous treatment through which drug can act directly to the target site. Eternal route of administration are very time taking as compared to parenteral and go through from the long process such as absorption of the drug then drug distribution throughout the body, metabolism and elimination of a drug. For emergency treatment intravenous therapy are used for rapid absorption and reaction.
Different types of catheter are used such as (1) Peripheral catheter in which catheter is inserted into peripheral veins (veins of arms, hands, legs and feet).(2) Peripherally Inserted Central Catheter (PICC) is the type in whichperipheral tubeisutilized when intravenous access is required for a long time. PICC used in a condition include: extended antibiotic therapy, long chemotherapy. (3)Central IV lines are used for the heart diseases in which catheters that are inserted into the large central vein commonly the superior or inferior vena cava in the right atrium of the heart. Due to the large diameter of these veins blood flow can be easily and faster than peripheral veins.(4) Subcutaneous injection port is utilized at the time when catheter is inserted into subcutaneous tissue and is used for the administration of insulin.
Many different types of drugs can be given by IV due to its fast effectiveness. Drugs that are most commonly given through this route of administration include:Antifungal drugs to treat fungal disease such as amphotericin. Antibiotics including gentamicin, vancomycin, Chemotherapy drugs, cisplatin, paclitaxel and vincristine. Drugs for low blood pressure neurotransmitter such as dopamine,epinephrine and norepinephrine and in Antibodies medications.
Patients with various conditions are treated with intravenous treatment includingAsthma, Migraines, Infectious conditions including viral diseases, hepatitis, rabies, Chronic diseases like fibromyalgia, Autoimmune diseases, Cancer and neurological diseases.
Administration of drug through IV is very fast and effective route of parenteral administration than eternal administration. Intravenous therapy are used in emergency conditions and it is usually safe route and cause rapid effectiveness as the drug directly act to the target site through blood streambut it can cause both acute and mild effects.
