Devroe S, et al. - In a single tertiary-referral hospital, researchers characterized the incidence, indications, anesthesia techniques and outcomes of pregnancies complicated by surgery. A retrospective review of hospital records from 2001 to 2016 of 171 patients who had non-obstetric surgery during the current pregnancy. During pregnancy, the incidence of non-obstetric surgery was 0.48%, mainly in the second trimester (44%) and under general anesthesia (81%). The results obtained from this retrospective, matched case-control cohort study indicate that pregnant women who had surgery delivered preterm more frequently and their babies had lower birth weights. The incidence of adverse pregnancy outcomes was not increased by laparoscopic surgery. Low birth weight was associated with general anesthesia. It remains speculative whether these associations suggest a cause or reflect the severity of the underlying condition.
