Medical research examines caesarean delivery complications and infection prevention

Recent medical research and clinical observations highlight different complications and preventative measures associated with caesarean deliveries.

In the United States, a study examining data from 2017 to 2024 found that the use of adjunctive azithromycin during unplanned caesarean sections has significantly increased, rising from 2.2% to 39.6%. This shift in practice is associated with a 20% relative risk reduction in postpartum infection rates, supporting the effectiveness of the treatment in real-world clinical settings.

Separately, clinical discussions have focused on the caesarean scar niche (CSN), an indentation in the uterine muscle at the site of a previous incision. This defect, often identified via transvaginal ultrasound, can lead to abnormal uterine bleeding, pelvic pain, or secondary infertility. Prevalence rates vary, but research indicates that the likelihood of developing a niche increases with each subsequent caesarean delivery.
