Estimation of Creatinine Clearance in Patients with Unstable Renal Function
Measurement of creatinine clearance (CCr) has long been a problem in sick patients, largely because of the need to collect a carefully timed urine specimen to determine it. However, a number of years ago, several methods were developed to estimate CCr without a urine specimen [1-4]. However, all these approaches only considered the situation where serum creatinine was stable. Because of this, a...
متن کاملCalculation of creatinine clearance from plasma creatinine.
Glomerular filtration rate (GFR) is commonly assessed by measurement of endogenous creatinine clearance (Ccr). Several formulae have been described to calculate Ccr from plasma creatinine. I have evaluated the effectiveness of four formulae in 35 healthy subjects (21M and 14F, 18-34 years) and in 41 patients (24M, 17F, 20-69 years) attending a renal clinic with diminished renal function (serum ...
متن کاملThe assessment of glomerular function: creatinine clearance or plasma creatinine?
Plasma creatinine concentration is superior to creatinine clearance for the detection of abnormal glomerular function, of changes of glomerular function in patients with chronic renal disease. Creatinine clearance should be abandoned as the routine assessment of glomerular function.
متن کاملThe endogenous creatinine clearance in normal subjects.
In normal subjects the glomerular filtration rate is relatively constant under standard conditions, and there is little or no change when the urine flow 'aries. It follows from this that the excretion rate of substances, which are filtered at the glomerulus and neither reabsorbed from nor secreted into the tubules, is constant. It is these substances which can be used to measure the filtration ...
متن کاملSimple estimate of creatinine clearance from plasma creatinine in neonates.
Thirteen newborn infants, 8 preterm and 5 term, with either mild or serious neonatal asphyxia were studied. From the first 24 hours of life to day 13, glomerular filtration rate (GFR) estimated by creatinine clearance was compared with the values obtained using Schwartz's formula: GFR (ml/min per 1.73 m2) = 0.55 x length (cm)/plasma creatinine (mg/100 ml). Both in term and preterm infants, valu...
