Management - Admit
acute - Aminoglycosides: gentamicin/ tobramycin (not for monotherapy), based on
complicated renal function (trough less than 2 and peak level 5-10mg/L) and do not give for
bacterial CKD
pyelonephritis - Ampicillin
- Cefazolin
- Cefotaxime and Ceftriaxon based on obesity and pulm disease
11. Urine analysis: Serum glucose at least 180mg/dl for glucose to appear in urine
glucose and ke-
tones Glucose in ua caused by:
- Fancone Syndrome (bad wall: caused by ahminoglycosides for example)
- DM
- Cushing's
- Vit C can give false negative
Ketones in urine:
- Alcohol
- Diabetic
- Starvation
12. Acute Kidney In- -Acute renal function loss with inability to excrete metabolic waste products (urea
jury nitrogen and creatinine) to inability to maintain fluid and electrolyte balance.
- Resolves within 3mo
- classified with RIFLE or etiology
13. RIFLE Risk: creatinine up x 1.5 from baseline, GFR decrease more than 25% and UO less
than 0.5ml/kg/hr for 6hr
Injury: creatinine up x 2 from baseline, GFR decrease more than 50% and UO less
than 0.5ml/kg/hr for 12hr
Failure: creatinine up x 1.5 from baseline, GFR decrease more than 25% and UO
