A patient of abdominal sepsis was staed on empirical treratment with intravenous ampicilling and gentamicin. Regarding the treatment of this patient, which statement is most accurate?
(Ref: KDT 6/e p741) Abdominal sepsis is a mixed type of infection caused by both aerobic and anaerobic organisms. Ampicillin and gentamicin will inhibit most of the aerobic organisms but these are not effective against anaerobic organisms. Therefore metronidazole or clindamycin should be included in the treatment regimen.
