title: Efficacy of a low dose of cefotaxime in serious chest infections.
abstract: The optimal antibiotic dosage in serious chest infections is not established and commonly used regimens may well be excessive. We have compared the efficacy of a low dose of cefotaxime (2 g every 12 h) with a more usual dose (2 g every 8 h) in a prospective, randomized study of the treatment of chest infections in the seriously ill. Fifty intensive care unit patients received either regimen for five days. The two groups appeared demographically comparable. Clinical resolution occurred in 86 percent, no change occurred in 4 percent, and deterioration occurred in 10 percent. Microbiologic clearance occurred in 52 percent of those in whom a pathogen was isolated (46 percent of patients). There was no significant difference in clinical or microbiologic response between the two regimens. It is concluded that cefotaxime in a dose of 2 g twice daily is effective in the treatment of serious chest infections.
