What is considered the first-line treatment for endometritis?

The first-line treatment for endometritis is typically a combination of clindamycin and gentamicin. This approach is effective because it covers a broad spectrum of potential pathogens, including anaerobic bacteria and aerobic Gram-negative bacteria, which are commonly implicated in endometrial infections following childbirth or miscarriage.

Clindamycin is well-known for its activity against anaerobic bacteria, particularly those that could be present in the endometrial cavity during an infection. Gentamicin provides coverage for aerobic Gram-negative organisms, ensuring that the treatment addresses both types of bacteria. The combination of these two antibiotics synergistically enhances the likelihood of an effective treatment outcome.

In contrast, other options listed would not cover the range of pathogens typically responsible for endometritis. For instance, metronidazole is typically used for anaerobic infections but does not provide the same breadth of coverage as clindamycin + gentamicin. Ciprofloxacin, although an antibiotic, does not specifically target the pathogens associated with endometritis the same way that clindamycin and gentamicin do. Tetracycline has limited use in this context as well, particularly because of its variable efficacy against the relevant bacteria. Thus, the combination of clindamycin and gent
