A 67-yeаr-оld mаn with bilаteral percutaneоus nephrоstomy tubes is brought to the emergency department by his wife because of altered mental status. The wife states he is not his "usual" self and responded with nonsensical phrases when she awoke him for breakfast. She add that, after both nephrostomy tubes were exchanged 4 days ago, the urine output from the right nephrostomy bag was relatively low, and that he complained of right flank pain yesterday. He has prostate cancer and receives leuprolide (Lupron Depot) injections every 3 months. He appears comfortable and diaphoretic. He is oriented to person but not to place or time. The right nephrostomy bag contains a small amount of cloudy urine; the left nephrostomy bag contains clear urine. Vitals include: Temperature is 36.8*C (98.2*F), pulse is 124/min, respirations 22/min, blood pressure is 76/50 mmHg when supine, oxygen saturation is 96%. Lab work includes: Hemoglobin 12 g/dL Leukocytes 22,000/mm3 Platelet count 180,000/mm3 Lactic acid 4.3 mmol/L The results of the blood and urine cultures are pending. Fluid resuscitation and broad-spectrum antibiotic therapy are initiated. A central venous catheter is placed and hemodynamic monitoring shows: After 2.5L of 0.9% NSS is infused, his blood pressure is 78/54 mmHg.
