What is the incidence of nonobstetric surgery in the pregnant patient?

The incidence of nonobstetric surgery during pregnancy is between 0.3% and 2%. There are approximately 3.5 million deliveries per year in the United States, which means that between 10,000 and 70,000 pregnant patients will require sur-gery. This may be an underestimate due to surgery performed prior to clinical recognition of pregnancy. Appendectomy is the most common nonobstetric operation during pregnancy. However, almost every type of surgical procedure has been successfully performed in the pregnant patient, including open-heart procedures with cardiopulmonary bypass, neuro-surgical procedures requiring hypotensive techniques and hypothermia, and liver transplantation.
