Flashcards in IV Therapy Deck (13):
Greater concentration than body fluid. D10W. Pull fluid into the vessels. Fluids flow to a high concentration
Less concentrated than body fluid. 0.45% NaCl. Pulls fluid into the tissue
IV flow rate
Total solution/# of hours to run= ml/h
Total volume x drop factor/ minutes= gtt/min
Sodium bicarb. Damaging to veins. Need big veins. If long term therapy need big vein.
Same concentration as the fluid of the person you're putting it into. Not appropriate for those in shock or elyte imbalances. 0.9% NaCl, D5W
Fluid comes out of the vessel and into the tissue. SnS- cool skin, swelling, pain, dec in flow rate. Tourniquet trick to check dripping. Discontinue IV, warm compress, elevate arm, start new IV above/proximal to site or other arm.
Extravasation of IV
Vesicant is medication or IV solution that causes blisters and tissue sloughing. Meds- gentamicin, penicillin, vancomycin, Dilantin, antineoplastics (vincas get warm compress rest get cool) , calcium, potassium, epinephrine. Pull out IV and aspirate.
Redness, warm, tender, swelling, leukocytosis. D/c IV, warm compress, restart IV at new site
Assess- ecchymosis, swelling, leakage of blood. D/c IV, apply pressure, ice bag 24h, restart IV in other arm
Clotting of IV
Assess- dec flow rate, back flow of blood into tubing. D/c, do not irrigate, milk, inc flow rate or hang solution higher, do not aspirate cannula, inject Urokinase
Placed in SVC or brachial cephalon vein. Midline between AC and clavicle. Stay up to 6 mo. Comp- pneumothorax, dysrhythmias, thrombophlebitis, nerve or tendon damage, resp distress, embolism. Imp- change dressing 2-3x/wk when wet or nonocclusive. Flush w/ 2ml NS followed by 5 ml heparin (100 u/ml) into each lumen. No BP.
MLC (midline catheter)
Enlarges 2 gauges and elongates 2.5 cm after insertion. Takes 2 hrs. Placed b/n AC and clavicle. In place 1-8 wks. Comp- thrombosis, phlebitis, air embolism, infection, vascular perforation. Flush with NS and heparin q12h or after meds
