What is the empiric regimen for septic abortion?

• A. Ampicillin + Metronidazole + Gentamicin
• B. Ampicillin alone
• C. Cefazolin
• D. Doxycycline + Gentamicin

Answer: (A)

In septic abortion, you must cover a broad range of bacteria that can infect the uterus—gram-positive, gram-negative, and anaerobic organisms. The uterus can harbor a mix of pathogens, including Streptococcus species, enteric gram-negatives like E. coli, and anaerobes such as Bacteroides. Because the infection can progress quickly, initial therapy aims for rapid, wide-spectrum coverage and then can be narrowed once cultures return and source control is achieved. The combination of ampicillin, gentamicin, and metronidazole provides that broad coverage. Ampicillin handles many gram-positive cocci and some enteric gram-negatives; gentamicin adds strong activity against many aerobic gram-negative organisms; metronidazole covers anaerobes. Together, they address the common polymicrobial flora seen in septic abortion and help prevent progression to sepsis while definitive management is pursued. Other regimens fall short mainly because they miss anaerobic coverage or broader enteric coverage, which is critical in this scenario.
