Purposes of IV therapy:
1. Supply fluids - crystalloids
2. Administer blood products - colloids.
3. Attain/maintain electrolyte balance
4. Provide nutrition
5. Administer medication
6. Blood specimen collection
Advantages of IV Therapy:
Rapid acting, can be used in emergencies, better control over administration, better absorption of medications, prevents irritation and pain to SQ and muscle tissue.
Crystalloid solutions include:
Sodium fluids for hydration, dextrose fluids - calories for energy, electrolyte solutions, Lactated ringers
Sodium fluids include:
0.9 Normal Saline is isotonic
1/2 NSS (0.45) Hypotonic
1/4 NSS (0.225%) Hypertonic
Dextrose fluids include:
1 gram of Dextrose/100 ml, calories for energy, correct hypoglycemia
Isotonic solution:
240-340 mOsm/liter
Hypotonic solution:
<240 mOsm/liter
0.45% NS
Hypertonic solution:
>340 mOsm/liter
5% glucose with NS
Is irritating
Osmolarity is:
Amount of solutes our blood has in it. Normal is 280-300
Colloid solutions include:
Blood/blood products
Nutrition includes:
TPN, vitamins, lipids and glucose
Nutrition provides:
Higher concentration of glucose and other minerals, vitamins, electrolytes, additives. Lipids may be added or given separately. Monitor lab values, glucose regularly, long term can cause liver damage.
Initiating IV therapy basic rules:
Work distal to proximal, avoid areas of flexion, never start on side of mastectomy
When choosing a site for phlebotomy:
Select larger median cubital, basilic, or cephalic veins, samples may be drawn from the same arm as a continuous IV if it is drawn below the IV. Avoid same side as mastectomy.
Feet and legs:
Must have physician order to use this site in adults due to complication. Ok to use in children.
Central venous lines in SVC are:
Short term central lines, jugular or subclavian, done in angio, bedside or OR, inserted directly into SVC, single, double, triple lumen, dressing change weekly, removal by physician or IV team.
Long term central lines:Longer than 2 weeks:
Broviac/Hickman, Groshong, Implanted ports, PICC
Broviac/Hickman and Groshong are:
Tunneled under the skin into SVC, single to triple lumen, removed by surgeon as adipose tissue gets around catheter, dressing changed weekly.
Implanted ports are:
Port inserted under skin, threaded into SVC, inserted in OR, single or double barrels, access by specialized nurses or IV team, HUBER needle, dressing change weekly by IV team, when incision is healed, pt may shower and swim, requires monthly flush, no outside port.
PICC are:
Antecubital, threaded into SVC, done at bedside or angio, elaborate sterile procedure, weekly dressing changes by IV team, removed by IV team.
Intraosseous are used:
Emergency, no other access possible, into the bone marrow.
Dialysis catheters are:
Larger, red and blue caps. NEVER USE FOR ANY OTHER PURPOSE!
Buretrols-volume control:
Backup safety device, will only get 1 hours of fluid.
Gravity IVs:
Need to count the drips for 1 minute, rate can change when patient changes position, NEVER hang potassium on gravity or any medication that must be controlled, such as heparin, pitocin, insulin, mag sulfate.
PCA: patient controlled analgesia:
Self administered pain medication, valuable and dangerous, stable blood level, client controlled and not nurse controlled, loading dose, continous, intermittent, lockout amount
Phlebitis is:
pain along vein above insertion site, redness along vein, warm to touch, hard or cord like, slight swelling, sluggish infusion
Causes of phlebitis: Mechanical irritation:
Too large of a needle in the vein and catheter tip not securely taped
Causes of phlebitis: Chemical irritation:
Improper mixed or diluted medications, too rapid infusion of medications or irritating solutions.
Treatment of phlebitis:
D/C the IV, restart in opposite arm, warm, moist soaks to area.
Infiltration is:
Fluid running outside vein, running into tissue under the vein.
Symptoms of infiltration includes:
Coolness at site, swollen when compared to other extremity, taut skin, slowing or sluggish rate, discomfort at site.
Causes of infiltration:
Puncture of vein during venipuncture, dislodgement of catheter from vein, poorly secured catheter, high delivery rate or pressure, over manipulation of iv device
Treatment of infiltration:
D/c infusion, restart in opposite arm, elevate arm if swollen, warm, moist packs for comfort.
Infection-local v/s systemic:
Redness, pain, swelling, foul smelling discharge, fever, increased WBC
Circulatory overload:
Too much primary maintenance fluid, too fast. Body can't excrete as fast as it goes in.
Circulatory overload symptoms:
1. slow increase in HR
2. SOB
3. distended neck veins
4. crackles on auscultation
5. wet cough
6. increased RR with dyspnea on exertion
7. weight gain and swelling of extremities
Prevention of circulatory overload:
Monitor iv rate every hour, never play catch up with fluids unless ordered, monitor VS and breath sounds
Calculating pediatric safe dose equation:
100 x first 10 kg =
50 x second 10 kg =
20 x remaining kg =
Add up and calculate how much fluid can get in 24 hrs. Divide by 24 to get hourly rate.
Treatment of circulatory overload:
Keep vein open, slow IV rate, check the client and notify physician, monitor VS, keep client warm, diuretics may be ordered, strict I&O, weights
Air embolism:
Pt gets too much air through iv.
Air embolism symptoms:
Hypotension, cyanosis, tachycardia, weak and thready pulse, wheeze, cough, dyspnea, mental status change, substernal chest pain
Prevention of air embolism:
Remove air from tubing
Remove air from syringes that are administering medications to the client.
Treatment of air embolism:
Call for help
place in Trendeleberg position and on left side
Admin O2
Monitor VS
Speed shock is:
Getting medication too fast. Is caused from rapid infusion of substance, usually medication, into circulation
Signs of speed shock are:
Flushing, HA, chest pain, vital sign changes.
Prevention of speed shock:
Know infusion rates for medications
Treatment of speed shock:
Usually supportive until system recovers.
Treatment of speed shock:
Usually supportive until system recovers.
Assess site every 4 hours, peds every hour, then:
IV set up q 8 hr, client - at least q 4 hr, physician orders for flow rate, fluid type, sites for therapy.
Asepsis includes:
Handwashing
Tubing change q 72 hr
IV bag change - q 24 hr
Redressing site q 72 hr
