Abstract
Sixty nine pairs of trough and peak serum levels of gentamicin were determined in sixty three cases of gentamicin therapy of suspected sepsis in newborn babies (dosage 3.46 +/- 0.42 mg/kg/day given once a day). Eighty four percent of the trough levels were below 2 mg/l (mean: 1.39-0.60 mg/l). Ninety three percent of the peak levels were between 4 mg/l and 12 mg/l (mean: 7.38-2.35 mg/l). Three peak levels (four percent) were in the potentially toxic range (above 12 mg/l) and eleven trough levels (sixteen percent) were in the potentially toxic range (above 2 mg/l). On the basis of these observations the recommended gentamicin doses during the first two weeks of life is 3-4 mg/kg/day applied once a day. In immature babies with birth weights below 1500 g the daily doses should not exceed 3 mg/kg were as term babies especially during the second week of life should be treated with a daily gentamicin doses of near to 4 mg/kg/day.
