Which factors influence preoperative assessment in pregnancy?

• A. Anesthesia choice to minimize fetal exposure
• B. Gestational age
• C. Maternal-fetal status
• D. Teratogenic risks

Answer: (A)

In pregnancy, the central aim of preoperative planning is to protect the fetus while keeping the mother safe. The most impactful factor you adjust in this planning is the anesthesia approach chosen to minimize fetal exposure. The technique and agents used during anesthesia directly determine how much drug reaches the fetus and how placental blood flow is affected. When feasible, regional anesthesia (such as spinal or epidural) limits fetal drug exposure and helps maintain stable uteroplacental perfusion, reducing fetal risk compared with systemic general anesthesia. This direct control over fetal exposure is why the anesthesia plan is the best factor to influence during preoperative assessment. Gestational age, maternal-fetal status, and teratogenic risks are important for shaping overall risk and perioperative management, but they feed into the plan rather than being the primary lever you adjust to minimize fetal exposure during the procedure.
