1 1 Using Hospital Pharmacy Reference Tools in IV Therapy Chuck DiTrapano, RPh Pharmacy Supervisor The Reading Hospital and Medical Center

2 2 Transition to Hospital Pharmacy RetailRetail –Dispensing –Prescription order entry –Orals, topical, some injectables …. –Insurance issues –Customer service –Compounding? –Physician calls –Inventory management HospitalHospital –Dispensing – 24 hour Drug Formulary Robotics, Automated Dispensing Cabinets BPCV (Barcode Verification) –Medication order entry –Interaction with nursing / drug administration issues –Same as retail + Injectable, infusion therapy, specialty services (chemotherapy, NICU, Pediatrics) –Stop order policy –Protocols –Clinical information systems –Clinical services –Drug Information Services –Physician Order Management (POM)

3 3 Transition to Hospital Pharmacy Dispensing Functions Unit Dose (12 / 24 hour) –Unit of use systems Floor stock (Automated Dispensing Cabinets- ADC) –SureMed, Omnicell, Pyxis Operating Room –Learn the acronyms (PACU, ED, ECU,NICU,MICU,SICU,CCU,PICU) Emergency Department (ED) Infusion Therapy Services

4 4 Omnicell Medication Dispensing Cabinets

5 5 IV Therapy Common Injectable routes of administration –Subcutaneous (SubQ, SQ, SC) –Intramuscular (IM) –Intravenous IV Push IV Intermittent Injection / Infusion IV Infusion

6 6 IV Push How fast is too fast for IV push medications? –IV Push should be defined by hospital policy –Concentration can effect IV rate Midazolam 1mg/mL vs 5 mg/mL –Medications that carry risk from rapid administration should be designated by hospital policy as IV Intermittent Infusion (IVPB) –Who can administer it?, How much drug can be administered? How fast can it be administered? Is there any monitoring required? Source: ISMP

7 7 IV Intermittent Injection / Infusion Intermittent infusion is used when a patient requires medications only at certain times, and does not require additional fluid. It can use the same techniques as an intravenous drip (pump or gravity drip), but after the complete dose of medication has been given, the tubing is disconnected from the IV access device Typical Volumes –25mL, 50mL, 100mL, 150mL Time of Infusion –15 to 60 minutes; typically Heparin Flushing / Central Line –SASH Long administration times / impact on nursing Policy on who can administer RN? LPN? Compatibility / Stability / Light Protection

8 8 IV Infusion Continuous Infusion LVP – Large Volume Parenteral –Typical volumes: 250mL, 500mL, 1000mL Taper –Many drugs require titration to clinical response of patient Infusion Lines –Peripheral Line –Central Line –PICC – Peripherally inserted central catheter Compatibility / Stability / Light Protection

9 9 IV Infusion (2) Central / Peripheral ? –Osmolarity Blood mOsm/kg 0.9% Sodium Chloride mOsm/L. (Isotonic) Dextrose 5% Water – 252 mOsm/L (Isotonic) 0.45% Sodium Chloride – 154 mOsm/L Hypertonic: over 900 mOsm/L Hypotonic – below 150 mOsm/L

10 10 IV Therapy Math Infusion Drip Rate Rx: Infusion of D5W 1,000 mL over 8 hours: 1000 mL/hour ÷ 8 hours = 125 mL / HOUR Rx: Infusion of D5W at 50 mL/hour: 1,000 mL ÷ 50 mL / hour = 20 hours / bag

11 11 IV Therapy Math mg / HOUR to mL / HOUR Rx: Diltiazem 10 mg/HOUR: Standard Concentration = 125 mg/125 mL (1 mg/mL) 10 mg / Hour ÷ 1 mg / mL = 10 mL / HOUR

12 12 IV Therapy Math mg / MINUTE to mL / HOUR Rx: Amiodarone 0.5 mg / MINUTE: Standard Concentration = 500 mg/250 mL (2 mg/mL) 0.5 mg/MINUTE x 60 minutes = 30 mg / HOUR 30 mg / HOUR ÷ 2 mg / mL = 15 mL / HOUR

13 13 IV Therapy Math Weight Based mg / kg / HOUR to mL / HOUR Rx: Aminophylline: 0.51 mg/kg/HOUR – pt wt: 80 kg Standard Concentration = 250 mg / 250 mL (1 mg/mL) 0.51 mg/kg/hour x 80 kg = 40.8 mg / hour 40.8 mg / hour ÷ 1 mg / mL = 40.8 mL / hour 41 mL / hour (rounded)

14 14 IV Therapy Math Weight Based mcg / kg / MINUTE to mL / HOUR Rx: DOPamine: 10 mcg / kg / minute – 80 kg patient Standard Concentration = 200 mg / 250 mL (0.8 mg/mL) 10 mcg/kg/minute x 80 kg x 60 minutes = 48,000 mcg / hour 0.8mg/mL x 1,000 mcg per mg = 800 mcg/mL 48,000 mcg / hour ÷ 800 mcg / mL = 60 mL / hour
