title: The evaluation of creatinine clearance in spinal cord injury patients.
abstract: The parameters of age, height, weight, serum creatinine and 24-hour urinary creatinine production were measured in 101 consecutive spinal cord injury patients (79 men and 22 women, 43 quadriplegics and 58 paraplegics) admitted to a rehabilitation hospital. Creatinine production was significantly lower than that of age and sex-matched hospitalized controls, upon whom commonly used nomograms for evaluation of endogenous creatinine clearance are based. Therefore, these nomograms grossly overestimate the creatinine clearance in paralyzed patients, which often results in aminoglycoside overdosage. Regression analysis identified the interval since injury and age as important determinants of creatinine production. We propose 2 simple equations and nomograms that should allow more accurate prediction of creatinine clearance in spinal cord injury patients.
