Surgeon-performed focused assessment with sonography for trauma as an early screening tool for pregnancy after trauma

Incidental pregnancy in trauma patients is associated with a high fetal mortality. Because of quality assurance reasons, many trauma centers have eliminated the rapid urine pregnancy screen. We sought to determine the utility and impact of the initial ultrasound examination in the diagnosis of pregnancy in female trauma patients.

Data were analyzed for all female trauma patients in whom pregnancy was diagnosed during a 5-year period.

One hundred one (70%) of 144 pregnant women had an initial ultrasound examination. Eighteen patents had newly diagnosed pregnancies, of whom 8 of 9 patients (89%) at > or = 8 weeks' gestation were diagnosed by the initial ultrasound. This directly contributed to a significant decrease in the amount of radiation exposure (p < 0.001) compared with patients diagnosed by serum beta-human chorionic gonadotropin.

An initial ultrasound examination should be considered in all female trauma patients of reproductive age. This may help to promote a reduction in fetal radiation exposure.
