Dialysis Notes

Intermittent HD assumes high-flux hemodialysis. CRRT assumes CVVHD with ultrafiltration rate 2L/h and residual native GFR < 10 mL/min.  For detailed view of dialysis dosing and evidence, see Dosing in Hemodialysis document.

Aztreonam lacks cross-reactivity with most other beta-lactams; however, most patients who have a recorded beta-lactam allergy can receive another beta-lactam through screening, test dosing, or skin testing. See Inpatient Allergy Guidelines
