High-dose methotrexate (MTX) can produce acute kidney injury, impairing MTX elimination. Continuous venovenous hemofiltration (CVVH) may enhance elimination in this setting, although its use is largely unstudied. A 79-year-old man received IV MTX for central nervous system lymphoma, and over a 34-h period his serum creatinine increased from 1.09 to 2.24 mg/dL. His serum MTX concentration (sMTX) at the end of this time period was 59.05 micromol/L. After urinary alkalinization and leucovorin and glucarpidase (CPDG2) treatment, sMTX decreased. Fluid overload ensued and CVVH was initiated. The initial MTX extraction ratio and clearance were 0.22 and 47.0 mL/min, respectively. No MTX extraction occurred at an sMTX of 0.15 micromol/L. Continuous venovenous hemodialysis was initiated, and sMTX further declined. CVVH may help eliminate MTX and provide renal replacement at moderate sMTX.

A freestanding, 911-receiving emergency department was implemented at Bellevue Hospital Center during the recovery efforts after Hurricane Sandy to compensate for the increased volume experienced at nearby hospitals. Because inpatient services at several hospitals remained closed for months, emergency volume increased significantly. Thus, in collaboration with the New York State Department of Health and other partners, the Health and Hospitals Corporation and Bellevue Hospital Center opened a freestanding emergency department without on-site inpatient care. The successful operation of this facility hinged on key partnerships with emergency medical services and nearby hospitals. Also essential was the establishment of an emergency critical care ward and a system to monitor emergency department utilization at affected hospitals. The results of this experience, we believe, can provide a model for future efforts to rebuild emergency care capacity after a natural disaster such as Hurricane Sandy.
