Gentamicin therapy monitoring in seriously compromised patients.

Gentamicin therapy was monitored in 30 patients with severe infection and other concomitant disease states. The application of the nomogram of Hull and Sarubbi [6] produced good plasma levels and disappearance of the infective agent without evidence of drug toxicity in 70% of patients. The remaining 30% did not respond satisfactorily to the treatment and showed low drug serum concentrations; and them had heavy fluid losses; when we modified their treatment, outside of the nomogram guidelines, we observed a better response. Since gentamicin distributes essentially in extracellular water, subjects who have alterations of body fluids regulation should be carefully controlled.
