Enteral administration is food or drug administration via the human gastrointestinal tract. This contrasts with parenteral nutrition or drug administration (Greek para , "besides" + enteros ), which occurs from routes outside the GI tract, such as intravenous routes.
The parenteral route is any route that is not enteral (par-+ enteral). Parenteral administration can be performed by injection, that is, using a needle (usually a hypodermic needle) and a syringe, [16] or by the insertion of an indwelling catheter. Locations of application of parenteral administration include: Central nervous system:
This often includes patients near the end of life (an estimated 1.65 million people are in hospice care in the US each year). [4] Because using the rectal route enables a rapid, safe, and lower cost alternative to administration of medications, [ 5 ] it may also facilitate the care of patients in long-term care or palliative care , or as an ...
Administration can take place via enteral administration (absorption of the drug through the gastrointestinal tract) [2] or parenteral administration (generally injection, infusion, or implantation). [3] [4] Contrast with topical administration where the effect is generally local. [4]
A syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it is actually a piston) that fits tightly within a cylindrical tube called a barrel. The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the ...
Patients who require nutrition therapy but have contraindications for or cannot tolerate enteral nutrition are appropriate candidates for parenteral nutrition. In the geriatric population, it is indicated if oral or enteral nutrition is impossible for 3 days or when oral or enteral nutrition is likely insufficient for more than 7 to 10 days.
A 10ml syringe needs to be used to ensure correct pressure, whether you are giving 5ml or 10ml. [ 1 ] Blood left in the cannula or hub can lead to clots forming and blocking the cannula. Flushing is required before a drip is connected to ensure that the IV is still patent.
A hypodermic syringe has the ability to retain liquid and blood in it up to years after the last use and a great deal of caution should be taken to use a new syringe every time. The hypodermic needle also serves an important role in research environments where sterile conditions are required.
