Gender: Male Height: 5’9” Weight: 180 lbs (= 81.8 kg) Serum creatinine: 0.9mg/dL Perform pharmacokinetic calculations Pharmacokinetic formulas Cockcroft and Gault equation: CrCl = [(140 - age) x IBW] / (Scr x 72) Volume of distribution (Vd) = Weight x 0.75 L/Kg Vancomycin: Kel = (0.00083 x CrCl) + 0.0044 T 1/2= 0.693 / Kel Calculate Loading dose (LD):_____mg. LD = 25mg/Kg Calculate Maintenance dose (MD):_____mg. MD = [(kel) x (Vd) x (ti) x (Cpeak desired) x (1 - e-kT)] / (1 - e-kti) Pharmacist Note Subjective / Objective: – 38 y/o caucasian male admitted with cellulitis, start vancomycin per pharmacy – Pertinent labs: • SCr: 0.9 mg/dL • WBC 18,000 Temp: 101.7 °F • 4/28/10 Wound cultures: pending Assessment / Plan: – Give vancomycin loading dose 2000mg IV x1, then start vancomycin 1750mg IV every 12 hours for target concentration of 10-15mcg/ml. – Check level on 4/30/10 before morning dose Pharmacy protocols Antibiotics – Vancomycin, Gentamicin, Amikacin, Tobramycin Blood thinners – Heparin, Enoxaparin, Fondaparinux and Warfarin (Coumadin®) Parenteral nutrition Renal dosage adjustment – Adjust medication doses based on kidney function Throughout the day… Communicate with nurses and doctors – Medication related issues • Intravenous compatibility, infusion rate • Drug-drug interactions, drug-food interactions • Clarify orders • Recommend antibiotic regimens Throughout the day… Respond to code blue – Cardiac / respiratory arrest – Provide emergency medications Conclusion Communication skills – Explain treatments to patients as well as coordinate treatment with other healthcare professionals Organization – Workload can be extremely hectic and stressful.
