Behavioural Disorders After Prenatal Exposure to Anesthesia for Maternal Surgery

( Br J Anaesth . 2024;132(5):899–910. doi: 10.1016/j.bja.2024.01.025) This study investigates the potential link between prenatal exposure to general anesthesia and the increased risk of children developing disruptive or internalizing behavioral disorders (DIBD). It stems from growing concerns about the safety of anesthesia, particularly for children under 3 years old and pregnant women in their third trimester, as outlined by the Food and Drug Administration (FDA) in 2016. Anesthetic agents cross the placenta and may impact neurodevelopment, with studies suggesting they can affect brain development during critical periods of gestation. This study focuses on the effects of prenatal exposure, considering that such exposures often result from maternal medical conditions rather than conditions in the child, which may help reduce confounding bias.
