A:
- No cultures to guide need for vancomycin but low risk for MRSA as swabs are negative on Oct 31/16
- Level is supratherapeutic and at steady state (target: 15-20mg/L). Level drawn and doses given appropriately. Level likely increased due to accumulation caused by AKI
- Renal fx improved with NS bolus, albumin and holding off diuretics yesterday. Starting midodrine and octreotide today. Renal function will likely be unstable over next few days
P:
- Decrease vancomycin dose to 750mg IV Q12H (at 100hr and 2300hr)

ID: 54 yo male admitted on Oct 29/16 for Fournier Gangrene

sCr 97 98 64
eGFR 79 76 112
WBC 8.3 9.0 15.0

Vancomycin trough level (Nov 7/16): 14.8mg/L (was 17.0mg/L on Nov 4/16)
No new cultures since last level
A:
- Vancomycin for empiric coverage of Fournier Gangrene until Nov 15/16
- All doses are given and levels drawn appropriately. Level is at steady state
- As per nurse, patient is very edematous and urine output is very low. This is reflected by his recent increase in serum creatinine. If patient is volume overloaded, this may also explain his increase in WBC and CBCs.
- Vancomycin level is slightly subtherapeutic (target: 15-20mg/L). However, there is a risk of accumulation with AKI
P:
- Continue current dose of vancomycin 750mg IV Q12H
