Retrospective anesthetic evaluation of non-obstetric surgery during pregnancy: single center experience

ABSTRACT

BACKGROUND: Laparoscopic procedures and ultrasonography are now commonly used in the obstetric field, and more non-obstetric procedures are being performed. However, little domestic data has been published on the topic. This present retrospective study investigated the clinical information and the effect on perinatal outcomes of non-obstetric surgery during pregnancy. METHODS: This retrospective study was performed using data of all adult pregnant women that underwent non-obstetric surgery at our institute between from July 2009 to December 2016. Data was collected from the institutional computerized database. The causes, types, and the gestational ages at surgery were collected as our primary outcomes. Basic characteristics of patients, operation times, anesthesia times, anesthetic methods, anesthetic agents, and adverse perinatal outcomes such as abortion or preterm delivery were evaluated as secondary outcomes. RESULTS: During the study period, there were 2,421 deliveries and 60 cases of non-obstetric surgery, an operation rate of 2.48%. The most common cause of non-obstetric surgery was abdominal surgery, followed by orthopedic surgery and neurosurgery. Most of abdominal surgeries were performed laparoscopically during the first trimester. The incidence of adverse perinatal outcomes was increased in the first trimester, was not related with anesthesia. CONCLUSIONS: The rate of non-obstetric surgery was found to be 2.48%, which was higher than those reported in previous domestic studies. This increase seems to have resulted from early diagnosis by ultrasonography and non-invasive surgery using laparoscopy. Adverse perinatal outcomes are not related with age, surgery and anesthetic-related factors but seem to be associated with surgery exposure stage, especially the first trimester.
