  7. 7. Lidocaine Clock 4 mg 2 mg 3 mg 1 mg 60 15 30 45
  8. 8. Lidocaine Clock <ul><li>You are preparing to start a Lidocaine infusion on your patient. You would like to give the patient 2 mg/min. Using the clock method, how many cc/hr should you set your pump at? </li></ul>
  9. 9. Lidocaine Clock 4 mg 2 mg 3 mg 1 mg 30 cc/hr 60 15 30 45
  10. 10. Dopamine Clock <ul><li>Dopamine is prepared by mixing: </li></ul><ul><ul><li>800 mg Dopamine in 500 mL D5W </li></ul></ul><ul><ul><li>400 mg Dopamine in 250 mL D5W </li></ul></ul><ul><li>800 mg / 500 mL = 1.6 mg/mL </li></ul><ul><li>Using a 60 gtt set </li></ul><ul><ul><li>60 gtts/min = 1 mL </li></ul></ul><ul><ul><li>1 mL = 1600 mcg </li></ul></ul>
  11. 11. Dopamine Clock 1600 mcg 800 mcg 1200 mcg 400 mcg 60 15 30 45
  12. 12. Dopamine Clock <ul><li>You are about to start a Dopamine drip on your patient. You would like to start this drip at 5 mcg/kg/min. Your patient weighs 100 kg. Using the clock method, how many cc/hr would you start your drip at? </li></ul>5 mcg X 100 kg = 500 mcg/min
  13. 13. Dopamine Clock 1600 mcg 800 mcg 1200 mcg 400 mcg 17 cc/hr 60 15 30 45
  14. 14. You are assuming care of a patient that is on a Dopamine drip currently running at 9 cc/hr. The patient’s weight is 84 kg. There is 400 mg of Dopamine in 250 mL of D5W. How many mcg/kg/min is this patient receiving?
  15. 15. Magic Number <ul><li>Works for any medication that is delivered in mcg/kg/min. </li></ul><ul><li>Sol’n Concentration (mcg) divided by 60 divided by pt weight (kg) = Magic Number. </li></ul><ul><li>Magic Number X cc/hr = mcg/kg/min </li></ul>
  16. 16. Magic Number <ul><li>Sol’n Concentration </li></ul><ul><ul><li>400mg / 250 mL = 1.6 mg </li></ul></ul><ul><ul><li>1.6 mg X 1000 = 1600 mcg </li></ul></ul><ul><li>1600 mcg / 60 cc = 26.6 </li></ul><ul><li>26.6 / 84 kg = .31 </li></ul><ul><li>.31 X 9 cc/hr = 2.84 mcg/kg/min </li></ul>
