Key result
Nonobstetric surgery during pregnancy increases the risk of complications such as preterm delivery and should be avoided if possible, but when required, it is best performed during the second trimester.
Why the study?
Cardiovascular, pulmonary, hematologic, and renal changes of pregnancy can increase surgical risk and must be considered when nonobstetric surgery is required.
This review highlights the physiological changes of pregnancy and provides practical recommendations for the perioperative management of pregnant women undergoing nonobstetric surgery to optimize maternal and fetal outcomes.
Requires obstetric involvement and pregnancy-physiology adjustments for nonobstetric surgery; leaves open optimal anesthesia and timing strategies.
Nonobstetric surgery during pregnancy should be avoided if possible, but when surgery is required, an obstetrician should be part of the perioperative team. In general, preoperative assessment is similar regardless of whether a woman is pregnant, but cardiovascular, pulmonary, hematologic, and renal changes of pregnancy can increase surgical risk and must be taken into account. Special management considerations include pregnancy-associated laboratory changes, timing of surgery, anesthesia choice, intubation precautions, patient positioning, preoperative blood typing, intraoperative fetal monitoring, and venous thromboembolism prophylaxis.

Aurón et al. (2020) conducted a review in Pregnant women undergoing nonobstetric surgery. Perioperative management and nonobstetric surgery was evaluated. Nonobstetric surgery during pregnancy increases the risk of complications such as preterm delivery and should be avoided if possible, but when required, it is best performed during the second trimester.
