Serum levels of gentamicin at peak and trough in neonates and infants.
The peak and the trough levels of serum gentamicin were determined in 50 cases of neonates and infants by microbiological assay method. The peak levels in the neonates and the infants were 5.98 +/- 0.48 and 4.63 +/- 0.31 mcg/ml respectively. The trough levels in the corresponding group were 1.06 +/- 0.19 and 0.94 +/- 0.23 mcg/ml. The mean values of the peak and trough levels of the antibiotic were 5.57 and 1.02 mcg/ml respectively. It was observed that there was a significant lower peak concentration in the infants than in the neonates. A significantly higher peak concentration of gentamicin was observed in babies aged under 7 days than in those above 7 days. The route of administration (between I/M and I/V) did not seem to have any effect on the peak and trough levels of the antibiotics.
