  • For hypotension: 250 ml NS bolus over 15 minutes prn SBP <90, may repeat X1 (total 2 boluses). This order to be discontinued for weight gain >5% of baseline.
  • Sodium bicarbonate-containing fluids to be used as follows:
    • If serum bicarbonate is 18-19, change IV fluids to 1 liter D5 1/2 NS with 50 mEq sodium bicarbonate, continuous at 75 mL/H. Once bicarbonate is at least 20, resume standing IV fluids above.

  • If creatinine >1.6, give 500 mL NS bolus over 60 minutes. Recheck creatinine 4 hours later, and if still >1.6, hold that day's dose of chemotherapy & call NP/MD.

Monitoring:

  • As an inpatient, check daily CBC with differential, comprehensive metabolic panel including sodium, potassium, chloride, bicarbonate, BUN, creatinine, glucose, calcium, magnesium, phosphate, alkaline phosphatase, AST, ALT, total bilirubin; once every 2 day monitoring of PT/PTT

Clinical scenario & comments:

  • 47 year-old gentleman with initially stage IIIC (T4b N1b M0) and now metastatic melanoma, s/p wide local excision, lymph node dissection, adjuvant interferon alfa-2B, with metastatic recurrence. At the time of treatment with this regimen, ipilimumab (which he later received) was not yet available outside of a clinical trial.
