[Clinical efficacy of aztreonam in refractory infections in children].

Aztreonam (AZT) is the first monobactam antibiotic that has significant activity in vitro against aerobic Gram-negative bacteria but not against Gram-positive or anaerobic bacteria. The agent was used 120-200 mg/kg in daily dose to treat 10 hospitalized cases of refractory infections in pediatric field. There were 3 cases of 1 pneumonia, 4 cases of urinary tract infections, 2 cases of pyogenic meningitis and 1 case of septicemia. Seven aerobic Gram-negative bacteria were isolated from patients and 4 bacteria were eradicated by treatment. Clinical cure was achieved in 8 out of 10 cases without adverse reaction or drug toxicity.
