  1. Parenteral Drug Administration

  2. Parenteral Administration • Parenteral – came from the Greek words “para enteron” meaning “to avoid the intestine.” Includes in its broadest sense, any drug (or fluid) whose delivery does not utilize the alimentary canal for entry into body tissues.

  3. Parenteral Administration 1. Intradermal Administration Action / Purpose • Local Effect • A small amount is injected so that volume does not interfere with wheal formation or cause a systemic reaction • Used for observation of an inflammatory (allergic) reaction to foreign proteins. Ex: tuberculin testing testing for drug and other allergic sensitivities some immunotherapy for cancer.

  4. Parenteral Administration Intradermal Sites • Locations are chosen so that an inflammatory reaction can be observed. Preferred areas: • lightly pigmented • thinly keratinized • hairless • ventral mid forearm • clavicular area of the chest • scapular areas of the back

  5. Parenteral Administration Intradermal Injection Sites • Clavicular Area • Clavicular Area Clavicular Area Scapular Area Ventral Mid Forearm

  6. Parenteral Administration Skin Layers - Injection Site Epidermis Layer Dermis Layer SubcutaneousLayer MuscleLayer

  7. Parenteral Administration Intradermal Equipment • Needle: 26 to 27 gauge • Syringe: • 1 ml calibrated in 0.01ml increments (usually 0.01 to 0.1 ml injected)

  8. Parenteral Administration Intradermal Technique: • Cleanse the area using a circular motion; observe sterile technique • Hold the skin taut • Insert the needle, bevel up, at a 10 to 15 degree angle; the outline of the needle under the skin should be visible.

  9. Parenteral Administration Intradermal Technique • Inject the medication slowly to form a wheal (blister or bleb) • Remove the needle slowly; do not recap

  10. Parenteral Administration Intradermal Technique • Do not massage the area; also instruct the client not to do so • Mark the area with a pen, and ask the client not to wash it off until read by a health care provider

  11. Parenteral Administration Intradermal Technique • Assess for allergic reaction in 24 – 72 hours; measure the diameter of local reaction. For tuberculin, measure only the indurated area; do not include redness in the measurement

  12. Parenteral Administration 2. Subcutaneous Injection Definition • a small thin needle is inserted beneath the skin and the drug injected slowly. • The drug moves from the small blood vessels into the bloodstream. • Usually slower in onset than with the IM route Purpose • It is done when a small amount of fluid is to be injected, the patient is unable to take the drug orally, or the drug is destroyed by intestinal secretions

  13. Parenteral Administration Site for injection • Abdomen • Upper hips • Upper back • Lateral upper arms • Lateral thighs Note: • Stay 1 inch away from the last injection. • Stay 2 inches away from your navel or scars. • Do not use areas that are bruised, tender or swollen. • The injection site should always be rotated so that consecutive injections are never given into the same area

  14. Parenteral Administration Equipment Needed • Needle – 25 to 27 gauge, ½ to 5/8 inches in length • Syringe – 1 to 3 mL • 2 alcohol wipes • Insulin syringe (for insulin use only)

  15. Parenteral Administration Technique • Wash and dry your hands • Prepare the medicine to be administered

  16. Parenteral Administration • Clean your skin with an alcohol pad. Start at the proposed site then wipe in a circular motion, moving outward with each circle to prepare an area 2-3 inches in diameter around the injection site. Let the alcohol air dry. • Gently pinch the skin at the injection site. Insert the needle through the skin at a 45 to 90 degrees angle so that the tip of the needle is under the skin and above the muscle layer.

  17. Parenteral Administration • Release the skin and gently pull back on the plunger to make sure the tip of the needle is not in a blood vessel. Note: DO NOT aspirate when using Heparin • Slowly inject the medication. When all the medication is injected, pull the needle out and quickly press the alcohol wipes onto the site for 30 to 60 seconds. Do not rub the skin.

  18. Parenteral Administration • Discard the syringe and attached needle into your puncture proof Sharps container. Do not recap the needle. • Wash and dry your hands

  19. Parenteral Administration 3. Intramuscular Injection Definition • An intramuscular (IM) injection is a shot where the needle goes into the muscle layer under the skin in order to deliver medicine. • Usually more rapid effect of drug than with subQ route • Used for irritating drugs, aqueous suspensions, and solutions in oils.

  20. Parenteral Administration Purpose • IM injections are also used to deliver medications that would otherwise be absorbed too slowly or made ineffective if taken by mouth. Examples of such medications include: • Certain antibiotics • Certain contraceptive hormones • Most vaccines • Epinephrine injections for people with severe allergic reactions

  21. Site for injection 1. Ventrogluteal Client Position: SUPINE LATERAL Note: Suited for deep IM or Z-track injection Parenteral Administration

  22. Site for injection 2. Dorsogluteal Client Position: PRONE Note: Suited for deep IM or Z-track injection Requires accurate site and technique Parenteral Administration

  23. Site for injection 3. Deltoid Client Position: LATERAL, PRONE, SITTING, SUPINE Note: Readily accesible Close to nerves Parenteral Administration

  24. Site for injection 4. Vastus Lateralis Client Position: SITTING, SUPINE Note: Good site for infants Free of major nerves Parenteral Administration

  25. Parenteral Administration Equipment Needed • Needle: 20-23 gauge, 18 gauge for blood products; 1-1.5 inches in length • Syringe: 1 to 3 ml (usually 0.5 to 1.5 ml injected)

  26. Parenteral Administration Technique • Same as subQ • Insert needle 90° into the muscles

  27. Parenteral Administration Technique Note: • Prepare all equipment • Use dart or pencil hold • If blood is present during aspiration, DO NOT INJECT.

  28. Parenteral Administration Technique Note: • Break through the skin quickly to minimize pain • Don’t change the direction of the needle as it goes in or comes out • Do not reuse disposable needles

  29. Parenteral Administration Z-track Technique • Prevents the medication from leaking back or entering into the subQ tissue. Note: Gluteal site is preferred

  30. Parenteral Administration 4. INTRAVENOUS ADMINISTRATION OF MEDICATION

  31. Medications are Administered Intravenously by the following methods: a.) Large volume infusion of intravenous fluid • Mixing a medication into a large-volume IV container. • Drugs are diluted in volumes of 1000 ml or 500 ml of compatible fluids. Fluids such as IV normal saline or Ringer’s lactate are frequently used. • Commonly added drugs are Potassium Chloride and Vitamins. • The medication can be added to the fluid container that is running or before it is hung and infusing.

  32. Procedure: • Wash hands and observe other appropriate infection control procedure. • Prepare medication ampule or vial for drug withdrawal. • Add the medication. To new IV container: • Locate the injection port and carefully remove its cover. Clean the port with antiseptic or alcohol swab. • Remove the needle cap from the syringe, insert the needle through the center of injection port, and inject the medication into the bag or bottle. • Mix the medication and solution by gently rotating the bag or bottle.

  33. Parenteral Administration Adding medications to Intravenous Fluid Container Equipment: • MAR or computer form • Correct medication • Diluent for medication in powdered form • Correct solution container, if a new one is to be attached • Antiseptic or alcohol swabs • Sterile syringes of appropriate size • IV additive label

  34. Complete the IV additive label with name and dose of medication, date, time, and nurse’s initials. Attached it upside down on the bag or bottle. • Clamp the IV tubing. Spike the bag or bottle with IV tubing and hang the IV. • Regulate infusion rate as ordered. • To an existing Infusion: • Determine that the IV solution in the container is sufficient for adding the medication. • Confirm the desired dilution of the medication, that is, the amount of medication per milliliter of solution

  35. Parenteral Administration • Closed the infusion clamp. • Wipe the medication port with the alcohol swab. • Remove the needle cover from the medication syringe. • While supporting and stabilizing the bag, carefully insert the syringe needle thorough the port and inject the medication • Remove the bag or bottle from the pole and gently rotate the bottle or bag. • Re-hang the container and regulate IV flow.

  36. Dispose of the equipment and supplies according to agency policies/practice. • Document the medication in the appropriate form in the client’s record.

  37. Parenteral Administration b.) Intermittent intravenous infusion (piggyback or tandem setups) • Methods of administering a medication mixed in a small amount of IV solution, such as 50 or 100 ml. • The drugs are administered at a regular intervals, such as every 4 hrs, with the drug being infused for a short period of time such as 30 to 60 minutes

  38. Parenteral Administration • Two commonly used additive or secondary IV setups are the tandem and the piggy back. • Traditionally the tubing of the secondary set has been attached to the ports of the primary infusion by inserting needle through port and taping it in place. Tandem setups – a second container is attached to the line of the first container at thelower, secondary port. It permits medications to be administered intermittently or simultaneously with the primary solution.

  39. Piggyback – a second set connects the second container to the tubing of the primary container at the upper port. This setup is used solely for intermittent drug administration.

  40. Parenteral Administration c.) Volume controlled infusion( often used for children) • Intermittent medications may also be administered by volume controlled infusion set such as Buretrol, Soluset, Volutrol, and Pediatrol. They are small fluid containers (100-150 ml in size) attached below the primary infusion container so that the medication is administered through the clients IV line. • Volume control sets are frequently used to infuse solutions into children and older clients when the volume administered is critical and must be carefully monitored.

  41. Adding Medication to a Volume-Control Infusion Set Equipment: • Medication in a vial or ampule • Sterile syringe • Antiseptic or alcohol swab Procedure: • Withdraw the required dose of the medication into a syringe. • Ensure that there is sufficient fluid in the volume-control fluid chamber to dilute the medication. Generally, at least 50 ml of fluid is used.

  42. Close the inflow to the fluid chamber by adjusting the upper roller or slide clamp above the fluid chamber; also ensure that the clamp on the air vent of the chamber is open. • Clean the medication port on the volume-control fluid chamber with an alcohol swab. • Inject the medication into the port of the partially filled volume control set. • Gently rotate the fluid chamber until the fluid is well mixed. • Open the line’s upper clamp, and regulate the flow by adjusting the lower roller or slide clamp below the fluid chamber. • Attach a medication label to the volume-control fluid chamber. • Document relevant data, and monitor the client and the infusion.

  43. Parenteral Administration d.) IV push or bolus • IV push or bolus is the intravenous administration of an undiluted drug directly into the systemic circulation. • It is used when a medication cannot be diluted or in an emergency. • An IV bolus can be introduced directly into the vein by venipuncture or into an existing IV line through an injection port or through an IV lock.

  44. Parenteral Administration Administering Intravenous Medications Using IV Push Equipment:For IV push for an existing line: • Medication in a vial or ampule • Sterile syringe • Sterile needles • Antiseptic swab

  45. Parenteral Administration For IV push for an IV lock • Medication in a vial or ampule • Sterile syringe (3 or 5 ml, to prepare medication) • Sterile syringe (3 ml, for saline or heparin flush) • Vial of normal saline to flush the IV catheter or vial of heparin flush or both • Sterile needles • Antiseptic swab • Disposable gloves

  46. Procedure: • Wash hands and observe other appropriate infection control procedures. • Prepare the medication. • Existing IV line: • Prepare the medication according to the manufacturer’s direction. • IV lock: • Flushing with saline – prepare two syringes, each with 1 ml of sterile normal saline. • Flushing with heparin and saline – prepare one syringe with 1 ml heparin flush solution, prepare two syringes with 1 ml each of sterile, normal saline, and draw up the medication into a syringe.

  47. Put a small-gauge needle on the syringe if using a needle system. • Wash hand and put clean gloves. • Provide client privacy. • Prepare the client. • Explain the purpose of the medication and how it will help, using language that the client can understand. Include relevant information about the effects of the medication. • Administer the medication by IV push. For existing IV line: • Identify the injection port closest to the client. • Clean the port with alcohol swab. • Stop the IV flow by closing clamp or pinching the tubing above the injection port.

  48. Parenteral Administration • Insert the needle of the syringe that contains the medication through the center of the port. • Pull back plunger of the syringe in order to aspirate a small amount of blood. • After observing the blood, continue to keep the clamp closed and inject the medication at the ordered rate. • Release the clamp or tubing. • After injecting the medication withdraw the needle.

  49. For IV lock: • Clean the diaphragm with antiseptic swab. • Insert the needle of the syringe containing normal saline through the center of the diaphragm and aspirate for blood. • Flush the lock by injecting 1 ml of saline slowly. • Remove the needle and syringe. • Clean the lock’s diaphragm with an anti septic swab. • Insert the needles of the syringe containing the prepared medication through the center of the diaphragm. • Inject the medication slowly at the recommended rate of infusion. • Withdraw the needle and syringe. • Clean the diaphragm of the lock.
