hospital course: this 85 year old white female with known aortic stenosis was a same day admission to the operating room for aortic valve replacement by dr. on . please see the operative report for details. she underwent aortic valve replacement with a 19-mm magna ease aortic valve bioprosthesis and patch aortoplasty with a bovine pericardial patch. her bypass time was 84 minutes with a crossclamp time of 69 minutes. post-operatively she was transferred to the cardiac surgery icu on neosynephrine and propofol infusions. her cardiac function was suboptimal and she was subsequently started on milrinone to support her cardiac function. additionally she was somewhat hypoxic and she was kept sedated through pod 1. on pod 2 her sedation was stopped, her milrinone was weaned off and diuretics were started. she failed to respond to lasix infusion. her platelet count fell and a heparin antibody test was negative. she remianed profoundly oliguric and her creatinine rose to 6. the lasix infusion at 20mg/hour was continued and cvvh was instituted. her urine output improved and diuretics were continued with cvvh. she remained hemodynamically stable. she took several days to awaken, but when her bun was below 100 she awoke and was intact. she was subsequently extubated and after a couple of days was able to swallow food and her medications. she required hemodialysis and as the renal function deteriorated again despite good urine output. a tunnelled dialysis line was placed by interventional radiology. she improved and her creatinne fell, she remained alert and intact. her renal numbers improved daily with good urine output off any diuretics. on her bun and creatinine were 69 and 1.8 repectively. the dialysis catheter was removed easily and the site was clean. physical therapy worked with her and a rehabilitation screen was performed for discharge as she remained very weak. cts and wires were removed in the icu in a timely fashion without problem. tube feedings were administered for a few days when she was sedated and intubated. on , pod 15, her bun and creatinine had fallen to 69 and 1.8. the dialysis catheter was removed sterilely with local anesthesia. she was discharged to for further recovery and rehabilitation. the renal numbers will be repeated there. medications on admission: amlodipine 5 mg daily nexium 40 mg daily losartan 50 mg
