  • Crystalloid-multiple preparations, isotonic (no real fluid shifts in avg pt, similar tonicity to blood plasma), hypotonic (less solute so will move into cells), hypertonic (high solute concen so fluid leave cells) Colloid-contains proteins or other molecules that remain in the intravascular space for long periods, tend to attract water NS and LR—2/3 of fluid lost to interstitial space within 1 hour of admin

    1. 1. IV Therapy and MedicationAdministrationCFD April QA TrainingHome
    2. 2. Intravenous Therapy Fluid/electrolyte administration Normal blood volume is 4.5-5L IV fluids do not replace blood or carry O2 Introduce medications Immediate drug absorption and effectsHome
    3. 3. Crystalloids-Fluids used in the field Normal Saline (1000 cc) 0.9% Sodium Chloride Isotonic solution Lactated Ringers (1000cc) Isotonic solution containing electrolytes such asNaCl, KCl, CaCl, and sodium lactate D5W (250cc) Hypotonic solution containing glucose to providecalories for metabolism Glucose moves into cells rapidlyHome
    4. 4. Equipment needed IV solution Medical—NS; Trauma—LR and/or NS; Med drip—D5W Administration set with extension tubing Macro drip (10-15 gtts/cc) for all IV’s Micro drip (60 gtts/cc) for medication drip Catheter Age >12 and need for fluid resus—16 or 18 g Age <12 and/or no need for fluid resus—20-24 g Age <6—may consider IntraosseousHome
    5. 5. Equipment needed (cont) Gloves Tape and bioclusive dressing Tourniquet Alcohol/betadine pad Use betadine in cases of suspected ETOH usewhere a crime may be involved (DUI) Ensure no allergies when using betadine Arm board Sharps containerHome
    6. 6. IV Complications Infiltration Fluid outside vessel causing swelling, pain, little orno IV flow Catheter shear Piece of catheter separates Air embolism Air enters blood stream (10-100 cc have beenfatal) Infection Localized or systemic Home
    7. 7. Saline lock vs. IV Saline lock Potential need for single medadministration IV Multiple meds and/or D50, fluid adminHome
    8. 8. Acceptable IV sites Arm Multiple veins in hand and arm Neck External jugular Leg Long saphenous vein* Anteromedial aspect of the tibia (IO)*Leg and foot veins involve a very high incidence of complications andshould only be used cautiously as a last resort.Home
    9. 9. Fluid bolus Maintain blood pressure between 90-100 mmHg systolic Give 250 cc boluses one at a time Closely monitor blood pressure, lungsounds and patient status prior to givingadditional bolusesHome
    10. 10. Medication AdministrationHome
    11. 11. Five Right’s1. Right patient2. Right dose3. Right medication4. Right route5. Right timeHome
    12. 12. IV medication packaging Vials (Single or Multi-dose) Draw equal amount of air into proper syringe Inject air into vial and withdraw medication Ampules Tap neck area to drain fluid Using alcohol prep or 4X4, snap neck of vial Withdraw proper amount of medication anddispose of ampule pieces in sharps container Remember, always use aseptic technique and removeair from syringe prior to injecting! Home
    13. 13.

    14. 14. Med Math The basics… use like units use common sense find a formula/system that works for youHome
    15. 15. Making weight….. 1 kilogram (kg) = 2.2 pounds (lb) Actual conversion Wt: 220 lb 220 divided by 2.2 = 100kg 10% or “Midnight” rule Half of 220 = 110 10% of 110 = 11 Subtract 11 from 110 = 99kgHome
    16. 16. Metric conversions 1 gram (g) = 1000 milligrams (mg) 1 mg = 1000 micrograms (mcg) 1 liter (L) = 1000 milliliters (ml) You need to give 500 mcg. How many mg?Mg - move decimal 3 places to the left = 0.5 mgOR 500 = half of 1000 so half of 1 = .5 mg You need to give 100 mg. How many mcg? Howmany g?mcg - move decimal point 3 places to the right = 100,000 mcgg - move decimal point 3 places to the left = 0.1 gHome
    17. 17. Basic calculationsDesired dose (D)Known dose on hand (H)x Unit of measure or volume on hand (Q)= volume or unit of measure to be administered (X)D X Q = XHHome
    18. 18. Example You are ordered to give 5 mg Valium IV. The labelstates there is 10 mg in 2cc (10mg/2cc). How manycc’s will you give? The equation will look like this:5mg x 2cc = X cc10 mg1 x 2 = X cc2X = 1 ccYou will give 1cc! Home
    19. 19. Calculations based on weightDesired dose (D) x Weight in kg (W)Known dose on hand (H)X Unit of measure or volume on hand (Q)= volume or unit of measure to be administered (X)D x W x Q = XHHome
    20. 20. Example You are to give 0.5 mg/kg IV push. Your patientweighs 80 kg. The drug comes packaged:100mg/10cc. How many mg will you give? Howmany cc’s will you deliver? Your equation to determine mg will look like this: 0.5 mg/kg x 80 kg = 40 mg to be given Your equation to determine cc will look like this: 40 mg x 10 cc = 4cc100 mgHome
    21. 21. Drip calculations“Clock” method (used only for 4:1 ratio)43 1601530452If your dose is 1 mg/min, your drip rate is 15 gtt/min.If the order is greater than 4 mg/min, add themtogether. A dose of 6 mg/min is 90 gtt/min (4 + 2 =6so 60 + 30 = 90) Home
    22. 22. Drip calculationsDesired dose x Size of bag x gtt set = gtt/minAmount of drug on hand The order is for 5 mg/min. You have a 500 cc bag of NS, a 60 gtt/ccadministration set, and 2 g of drug on hand. How many gtt/min will youadminister?5 mg/min x 500 cc x 60 gtt/cc = 75 gtt/min2000 mgNote: If the dose is weight based, determine the total dose prior tobeginning the equation or multiply everything by the number of kg.Home
    23. 23. Routes to administer medications Enteral (via digestive tract) Oral (by mouth, PO)10-90 minutes to begin workingAffected by digestion and absorption Sublingual (under the tongue, SL)3-5 min Rectal (via the rectum, RE)5-30 minutesHome
    24. 24. Med routes (cont) Parenteral Inhalation (IH) Endotracheal (ET) Transdermal (TD)Time for effects variable based on medication Subcutaneous (SQ) Intramuscular (IM) Intravenous/Intraosseous (IV/IO)Home
    25. 25. Medication delivery through the airway Inhalation Takes effect in 2-3 min Given by hand held nebulizer (HHN) ormetered dose inhaler (MDI) Endotracheal Takes effect in 2-3 min Must double IV dose and flush with saline Narcan, Epinephrine, Lidocaine, AtropineHome
    26. 26. Intramuscular and Subcutaneous Intramuscular Takes effect in 10-20 min Delivery90 degree angle, 1 ½ inch minimum needle Subcutaneous Takes effect in 15-30 min Delivery45 degree angle, 1/2-1 inch needleHome
    27. 27. Standing Orders vs. Physician Order Standing Order Able to give med or start procedure if patientmeets certain preset criteria Physician Order Must request med or procedure from on linedoctorWhen giving report, ask for doctor before beginningGive report and paint clear picture of patient statusSpecifically request the medication and dose you want togiveHome
    28. 28. Things to look for… Onset of Action-time between administration and first effectsseen Duration of Action-time after administration until effects are lastseen Side effect-undesirable and often unavoidable effect thatoccurs. Effects are not the original reason for administering thedrug. Interaction-good or bad effects that occur with administration ofmultiple drugs. Can increase or decrease effects of one or bothmeds. Synergism-action of a combination of drugs that is greater thanone drug alone Allergy-systemic reaction to a drug involving the immuneresponse Untoward effect-side effect that becomes harmful to the patientHome
