2. IV Therapy Administration of fluids, electrolytes, nutrients, or medications by the venous route Clients receiving IV therapy require constant monitoring for complications
5. Indication for IV Therapy Establish or maintain a fluid or electrolyte balance Administer continuous or intermittent medication Administer bolus medication Administer fluid to keep vein open (KVO) Administer blood or blood components
6. Indication for IV Therapy Administer intravenous anesthetics Maintain or correct a patient's nutritional state Administer diagnostic reagents Monitor hemodynamic functions
7. Major Types of IV Fluids Isotonic Fluids – increases extracellular fluid volume O.9% NS-expands intravascular volume 5% dextrose & water-lowers serum Na+
18. Hypotonic fluids Contain a lower number of molecules than serum Fluid shifts from the intravascular space to the interstitial space (represented by the green arrows). Decreases the interstitial space osmolarity (because of the increase of fluid and constant number of molecules within it) which then causes fluid to move into the cells.
20. Hypertonic Fluids Increases osmotic pressure, drawing fluid from cells D5% in 0.45% NS-provides sodium chloride
21. Hypertonic fluids> 295 mOsm/kg Higher osmolarity than serum Stabilize blood pressure, increase urine output, and reduce edema. Rarely used in the prehospital setting Dangerous in the setting of cell dehydration Examples: 9.0% NS, blood products, and albumin
22. Hypertonic Solution Pulls fluid & electrolytes from the intracellular & interstitial compartment into the intravascular compartment
23. Hypertonic fluids Contain a higher number of molecules than serum Increases the interstitial space osmolarity (because of the loss of fluid and constant number of molecules within it) that then causes fluid to leak out of the cells.
25. Crystalloid Ideal for patients who need fluid replacement. Used as a replacement to support blood pressure from blood loss Examples: Lactated Ringer's (LR), NS (normal saline)
27. Colloids Draw fluid from the interstitial & intracellular compartments into the vascular compartment Reduce edema (pulmonary or cerebral edema) while expanding the vascular compartment. Examples: albumin and steroids
29. Starting an IV is an art-form which is learned with experience accumulated after performing many IVs. Some patients are easy but many are difficult.
30. IV Equipment Peripheral IV & Heparin locks – establish a venous route in those clients whose condition may change rapidly Vascular Access Devices – allow long-term IV therapy
31. Steel Needles: Butterfly catheter Deliver small quantities of medicines Deliver fluids via the scalp veins in infants Draw blood samples (although not routinely, since the small diameter may damage blood cells). Small gauge needles
32. Over the Needle Catheters Example: peripheral IV catheter. This is the kind of catheter you will primarily be using.
33. A Word About Gauges Gauge is the diameter of catheter The smaller the diameter, the larger the gauge A 22-gauge catheter is smaller than a 14-gauge catheter The greater the diameter, the more fluid can be delivered
34. A Word About Gauges To deliver large amounts of fluid, you should select a large vein and use a 14 or 16-gauge catheter
35. A Word About Gauges To administer medications, an 18 or 20-gauge catheter in a smaller vein will do.
36. Veins of the Hand Digital Dorsal veins (1) Dorsal Metacarpal veins (2) Dorsal venous network (3) Cephalic vein (4) Basilic vein (5)
37. Veins of the Forearm Cephalic vein (1) Median Cubital vein (2) Accessory Cephalic vein (3) Basilic vein (4) Cephalic vein (5) Median antebrachial vein (6)
38.
39. Failed cannulation attempts of antecubital veins can cause problems in the event of a successful cannulation further down
44. Points to Remember Dorsal veins are often quite handy Metacarpals splint cannulae well They can be quite small. If the patient is elderly, look elsewhere Lack of turgor in the skin & loss of subcutaneous tissue make it quite difficult to cannulate these veins
45.
46. Avoid areas where cannulation or venipuncture has previously taken place
47.
48. Choose a vein that has a firm, round appearance or feel when palpated
49.
50. Inspect the fluid bag: desired fluid fluid is clear bag is not leaking bag is not expired
51.
52. Do not let the ends of the tubing become contaminated.
53. Close the flow regulator (roll the wheel away from the end you will attach to the fluid bag).
54.
55. Prepare the IVF administration set If you overfill the chamber, lower the bag below the level of the drip chamber and squeeze some fluid back into the fluid bag. Hold the fluid bag higher than the drip chamber of the administration set Squeeze the drip chamber once or twice to start the flow. Fill the drip chamber to the marker line (approximately one-third full).
56.
57. Let it run into a trash can or even the (now empty) wrapper the fluid bag came in.
58.
59. Turn off the flow & place the sterile cap back on the end of the administration set (if you've had to remove it).
62. It should be tight enough to visibly indent the skin, but not cause the patient discomfort
63. Have the patient make a fist several times in order to maximize venous engorgement
64.
65.
66. If you cannot easily see a suitable vein, you can sometimes feel them by palpating the arm using your fingers (not your thumb)
67. The vein will feel like an elastic tube that "gives" under pressure
68.
69. If after a meticulous search no veins are found, then release the tourniquet from above the elbow and place it around the forearm and search in the distal forearm, wrist and hand
70. If still no suitable veins are found, then you will have to move to the other arm.
74. Allow it to dry. Use both in a circular motion starting with the entry site and extending outward about 2 inches.
75.
76. Perform the venipuncture To puncture the vein, hold the catheter in your dominant hand With the bevel up, enter the skin at about a 30 to 45 degree angle and in the direction of the vein Use a quick, short, jabbing motion After entering the skin, reduce the angle of the catheter until it is nearly parallel to the skin
77.
78. Many people use their thumb for this. Pull the skin distally toward the wrist in the opposite direction the needle will be advancing.
79. Be careful not to press too hard which will compress blood flow in the vein and cause the vein to collapse
98. Dispose of the needle in an appropriate sharps container.
99. NEVER reinsert the needle into the plastic catheter while it is in the patient's arm!
100.
101.
102. If Successful Label the IV site with the date, time, and your initials. Monitor the infusion for proper flow into the vein (in other words, watch for infiltration).
103. IV Therapy: Sample IV Orders 1 L 5%D/0.45 NaCl with 20 mEq KCL at 125cc/hr 1000 ml D5 ½ NS with 20 mEq KCL every eight hours 1000 ml D5 ½ NS with 20 mEq KCL to run in 8 hrs
104. Flow Rates: Microdrip sets Allow 60 drops (gtts) / mL through a small needle into the drip chamber Good for medication administration or pediatric fluid delivery
105. Flow Rates: Macrodrip sets Allow 10 to 15 drops / mL into the drip chamber Great for rapid fluid delivery Also used for routine fluid delivery and KVO
106. Flow Rates How much fluid do you want your patient to receive each hour? “Keep the Vein Open” (KVO), infusing IVF slowly to keep the vein patent, small amount of volume infused Faster flow rate are expressed in mLs/hr Maintenance“ amount: NS at 125 ml/hr Your patient would receive 125 mL of fluid every hour
107.
108. This is usually done by counting the number of drops that fall into the clear drip chamber on the IV administration set in one minute.
109. To do this, you must know what size administration set you are using (micro or macrodrip).
110.
111. IV Therapy: IV Label Amount & Type of solution Additives & their concentrations Rate & duration of IV therapy Expiration date Initials of pharmacist who prepared Pt’s name & room # Date & time started RN initials
112. IV Therapy: Documentation Type of fluid & flow rate Insertion site location (L forearm, R hand, L antecubital) State of IV site (swelling, reddness, pain) Patient’s response to therapy IV intake on I & O flow record
120. IV Therapy: Nursing Care Monitor IV site & infusion every 2 hours Pt age, size, status, c/o discomfort, teaching Intake & Output No IV solution hung > 24 hrs Monitor for complications
121. IV Therapy: Nursing Care Change IV site, dressing, tubing per institution policy (standard q 72-96 hrs No application of antimicrobial ointment on catheter site Prevent neddle stick injury Standard precautions
122. Complications of IV Therapy Phebitis Pain, increased skin temp, erythema, along path of vein
123. Complications of IV Therapy Infection IV site red, swollen, warm, tender; purulent foul smelling drainage
124. Complications of IV Therapy Hematoma Discolored area/bruising around IV site, pain, swelling
125. Complications of IV Therapy Infiltration Swelling, possible pitting edema, pallor, coolness pain at site, decrease flow
126. Complications of IV Therapy Extravasation - inadvertent administration of a vesicant substance into the tissues can have disastrous outcome.
137. Discontinue an IV (cont) Place a 4 x 4 gauze over the site Gently slide the plastic catheter out of the patient's arm Use direct pressure for a few minutes to control any bleeding. Place a band aide over the site.
146. Intermittent therapy (saline lock) Swab injection port with alcohol at each step. S: flush with 2 ml saline. A: administer medication at prescribed rate using a short needle with a gauge equal to or smaller than catheter (25 g, 1/2 in). S: flush with 2 ml saline (maintain positive pressure to prevent blood back-up into catheter). Not required if drug compatible with heparin. H: flush with 10-100 units heparin if required by facility policy.

Notes de l'éditeur
Evaluate the site for infection, redness along the vein Edema or infiltration, location of the cath (over a joint); Consider changing site
Irritation from medication; length of time the IV has been in the present site
Speed shock is a systemic reaction that occurs because of a rapid infusion of drugs or bolus infusion which causes the drug to reach toxic levels quickly. However the client received a bolus of NS, not drugs. The symptoms the client is experiencing point towars circulatory overload which occurs when fluids are infused at a rate greater than the client’s system can accommodate. Slow the IV, notify the physician, elevate the HOB, monitor vital signs, prepare to give O2 and diuretics. Prevent this from occurring by monitoring the IV infusion carefully and preferably using an IV pump. Monitor I & O
