The use of tombramycin in the management of severe infections. Clinical and pharmacological data.

Tobramycin was used in the treatment of 35 severe infections. Its clinical effectiveness was confirmed in broncho-pulmonary infections without septicemia and in septicemia without lung involvement. Poor results were obtained in septicemia where the initial site 9 infection was in the lungs. This antibiotic appeared as a very good antistaphylococcal agent. In vitro superiority over gentamicin against Pseudomonas was not be confirmed clinically. Tobramycin deserves to be administered initially in serious infections because of the possibility that the causative organism might be a gentamicin-resistant, tobramycin susceptible strain. Three such cases were observed in our 35 patients. This susceptibility dissociation in favor of tobramycin was demonstrated in two strains of Klebsiella and one strain of Enterobacter. A dosage regimen in patients with impaired renal function is proposed. It requires confirmation.
