An evaluation of gentamicin dosing according to renal function in neonates with suspected sepsis.

Aminoglycoside antibiotics are frequently used for the treatment of suspected and confirmed sepsis in the newborn patient. In an attempt to evaluate gentamicin dosing based on serum creatinine concentrations, two groups of neonates were studied (infants less than 34 weeks n = 8 and greater than 34 weeks n = 14). The dosing interval was adjusted per protocol depending on the serum creatinine concentrations. Analysis of the results indicate reasonable therapeutic serum gentamicin trough and peak concentrations in most infants.
