IV drip

Di- and mono-esters of phthalic acid, an ortho-dicarboxylic acid derivative of benzene. These compounds are widely used as industrial plasticizers to coat polyvinylchloride surfaces of plastics used in food packaging and medical devices (iv drip bags, blood storage bags, etc.) and are common environmental contaminants. Several phthalate mono-esters are peroxisome proliferator chemicals and can activate the peroxisome proliferator-activated receptor PPAR. 

Medicated IV drips are solutions that have potent medications added. When administered, these infusions require extreme care and meticulous observation so that exactly the prescribed amount of medication in solution is administered to the patient. Generally, infusion pump or a controlled volume chamber and a microdrip set are used to administer medicated IV drips. 

Maintenance dose - 100 units/kg/dose IV drip every 4 hours, or 20,000 units/m /24 hours continuous IV infusion. 

Administer by slow IV drip infusion only, either as continuous or intermittent infusion. Do not use equipment containing aluminum (eg, needles, cannulae). If used with a primary IV fluid system, discontinue the primary solution during infusion. Do not give by direct IV bolus injection because of the low pH (0.5 to 2) of the reconstituted product. The drug must be further diluted and neutralized for infusion. Do not introduce additives into the solution. 

With IV CyC - - 5FU - - MTX it cannot be established which IMN in the combination is effective and which induces adverse effects. Immediate allergic reactions arising during IV drips may indicate the IMN concerned. Drug interactions among 5FU, MTX and CyC by IVT and oral CyS, MMF, and MTX have not been studied. It has been established however that quinolone antibiotics may interact with IMNs. 

Intravenous (IV) delivery has two variations injection and infusion. In an injection, the entire dose is rapidly placed in a vein via a syringe and needle. The dose is called an IV bolus. An IV infusion, sometimes called an IV drip, involves administering a drug from an IV bag over a predetermined amount of time. The concentration of the drug solution and IV drip rate determine the eventual drug concentration in the patients blood.

Staff at the hospital reduced Eddie s temperature and, not realizing how much water he had recently taken, set up an intravenous (IV) drip of 5% dextrose in order to rehydrate him. He was not producing urine, and gradually became weaker, irritable and more confused. His skin looked puffy and oedema in dependent parts of his body soon developed. A blood sample showed the following ... 

Case Conclusion Despite treatment with nitroglycerin, metoprolol, and heparin drips in the ED, PB continued to have chest pain. He was scheduled for an emergent coronary catheterization to improve symptoms and prevent further ischemia. He was started on an eptifibatide IV drip for 24 hours and oral clopidogrel for 4 weeks. 

To prevent dehydration, intravenous (IV) drips are administered to many hospital patients. A solution containing sodium chloride and glucose is commonly used. 

Give IV push or IV drip to maintain muscle paralysis. 

Methohexital (1 mg/kg in 1% solution given at a rate of 1 mL/5 seconds) is used for induction of anesthesia lasting 5 to 7 minutes. Maintenance of anesthesia may be accomplished by intermittent injections of 1% solution or by continuous IV drip of a 0.2% solution. Intermittent injections of about 20 to 40 mg (2 to 4 ml of a 1% solution) may be given as required, usually every 4 to 7 minutes. For continuous drip, the average rate of administration is about 3 mL of a 0.2% solution/min (1 drop/second). Methohexital should not be mixed in the same syringe or administered simultaneously during IV infusion through the same needle with acid solutions, such as atropine sulfate, metocurine iodide, and succinylcholine chloride. 

Polymyxin B, a polypeptide antibiotic (500,000 units in 300 to 500 mL of 5% dextrose in water for continuous IV drip), is used in acute infections caused by susceptible strains of Pseudomonas aeruginosa. It may be used topically and subconjunctivally in the treatment of infections of the eye caused by susceptible strains of P. aeruginosa. 

Dopamine is normally administered by IV drip. The general effect of the drug is very brief, so the effects may be controlled by the dose and rate of administration. 

These drugs are administered by slow intravenous route, either by intramuscular (IM) injection or by slow infusion (IV drip). 

Dose For congenital heart disease by IV drip starting with doses of 100 nanograms per kg body weight per minute. 

Noticing that an IV drip had finished before it shonld have done ft s ohvions. The nurse said that it would take 20 minutes, hut it starts beeping after 8 minutes (indicating the end of the infusion bag). It turned out to be the confusion of a 50 ml bag with a 100 ml bag. ... 

Example 2-8. Radioactive iodine is used to image the thyroid gland. Typically, a saline solution of Na l is administered to the patient by an IV drip. Predict the most likely type of radioactive decay for this nuclide and calculate Q for the reaction. Given that the half-life of l is 8.025 days, what percentage of the isotope will have decayed during the 2.0-h procedure ... 

Many thermoplastics become britde at room temperature, which severely limits their utility. This is true of PVC. Pure PVC is highly susceptible to cracking at room temperature and is therefore useless for most appUcadons. To avoid this problem, the polymer can be prepared in the presence of small molecules called plasticizers. These molecules become trapped between the polymer chains where they function as lubricants. Common plasticizers are dialkyl phthalates, such as di-2-ethylhexyl phthalate used in vinyl upholstery, raincoats, shower curtains, inflatable boats, and garden hoses. Some plasticizers evaporate slowly with time, and the polymer ultimately returns to a britde state in which it can be easily cracked. Intravenous (IV) drip bags used in hospitals are typically made from PVC with plasticizers.
