**13. Non-obstetric anesthesia during pregnancy**

Approximately 2% of pregnant women require non-obstetric surgery in any trimester [18]. Negative results occur after non-obstetric surgery during pregnancy. Maternal death was reported in 1/12.542 cases (0.006%), and the risk of miscarriage or fetal loss was reported to be 10.5% in the first trimester before the 20th week [19]. This rate was found to be 5.8% when all trimesters were evaluated. The practices to be followed by the ACOG Committee regarding non-obstetric surgeries are summarized in **Table 4** [20].

Airway management can be challenging because of breast engorgement, and weight gain. Edema and bleeding may occur during tracheal intubation or supraglottic airway device insertion. Reduced functional residual capacity and high oxygen consumption should be balanced with apneic oxygenation and preoxygenation. Preparations should be made according to difficult airway management guidelines.
