IV therapyPART 2 Catherine Luksic BSN, RN
Methods of iv infusion • Primary infusion • “maintenance infusion” • “continuous infusion” • Via gravity • Via electronic pump • Secondary infusion • “piggyback” • “IVPB” • Usually via electronic pump
Equipment: IV tubing • Primary IV administration set • Gravity infusion • Electronic pump infusion • Secondary IV administration set • “piggyback tubing” • Blood administration Y set • Extension tubing • Intermittent infusion lock • HL or SL
Methods of IV Infusion • Gravity Drip • Manually set, regulated w/ roller clamp • Simplest method • Count drops manually • Macrodrip tubing - drop factor determined by manufacturer • Can range from 10-20 gtts/mL(common 10gtts/mL) • standard primary tubing • for rapid infusions • Microdrip tubing - 60gtts/mL • Used for peds, elderly, slower rates
Gravity Infusion • Advantages: • Easy • Does not require power source or pump • Can set-up quickly • Disadvantages: • Not greatly accurate • No free-flow prevention • Room for error
Calculating a gravity IV rate • Volume ordered to be infused • 1000 ml or 1000 cc • Drop factor of tubing being used • Rate of infusion as per order • 100 ml /hr (or 100 cc/hr) **refer to IV calculations worksheets
Rate of IV INFUSION • Check physician orders ! • Gravity drip or electronic pump ? • cc/hr = ml/hr • KVO (10-20 ml/hr) • TKO • Check IV site & IV rate at least every hour
Priming • Refer to procedure • Maintain sterility • Remember to close the roller clamp 1st ** • ?? Invert all Y-sites and tap to remove air • Demonstration • Practice
Factors that will affect flow rate • Height of bag • 36 inches above heart • Position of roller clamp • is it open or closed ? • Patency of tubing • Check for kinks
Slowed Infusion Rate • Check rate - has it been changed? • Check tubing - is it kinked? • Check clamp(s) - are they open? • Check site - • is cath or vein being compressed? • ANY abnormality? • Look for sign of infiltration
Electronic Control Devices • Purpose – improve accuracy of delivery. • Requires power source • Deliver a preset fluid rate over a specified period • Uses constant force • Always use pump w/ TPN, central lines, titrated medications, blood products
Electronic Pump Alarms(Common) • Occlusion • Air-in line • Infusion complete • Power
Electronic IV Pumps • SINGLE CHANNEL • MULTI-CHANNEL • PCA (Patient controlled analgesia) • AMBULATORY IV PUMPS • Home care use
NURSING PROCESS • ASSESSMENT • DIAGNOSIS • PLANNING • IMPLEMENTATION • EVALUATION
ASSESSMENT • FIRST STEP, AS ALWAYS • chronic conditions • use of long-term medications (anticoagulants) • previous IV experiences/problems • allergies (especially latex & antimicrobial agents) • hand dominance • Skin *Cultural considerations, communication barriers, level of understanding
Assessment • Physical exam • Neurological status – AAO, ability to understand and cooperate • Cardiovascular status – color, pulses, edema, appearance of veins • Skin – bruising, rashes, lesions
NURSING DIAGNOSIS • Examples: • Risk for injury related to (lack of knowledge regarding equipment) • Knowledge deficit related to (new IV insertion) AEB (pt verbalization …) • Impaired physical mobility related to placement of peripheral IV AEB… • Anxiety related to (initiation of IV therapy) AEB... • Alteration in comfort: Pain
Planning • Patient outcomes and goals - what do you (and the patient!) expect. • Ex: Pt. will remain free of S/S of complications related to IV therapy • More specific – Pt. will remain free of signs of phlebitis
Implementation • Nursing Care: • Check site HOURLY for complications - redness, pain, edema, infiltration • Instruct pt. to call nurse immediately: pain, bleeding, other concerns. • Instruct pt. to call nurse if pump alarm sounds. • Maintain correct infusion rate as ordered. • Secure IV (to prevent accidental dislodging of catheter during movement). • Change tubing according to hospital policy (usually q 72 hr.) • Change IV site according to hospital policy (usually q 72 hrs.)
Implementation • Nursing Care: • 2011 Infusion Nurse Society (recommendations) • Do not change IV tubing more frequently than q 96 hrs. • If IVPB tubing is detached from continuous tubing, change q 24 hrs.
Evaluation • How will you know if the goal/outcome has been achieved? • Assessment • Patient record • Lab values • Communication
