Abstract

During a 9 1/2-year period, 76 pregnant women who sustained blunt trauma were admitted to a level-I trauma center. Fetal outcome was ascertained in 59 patients (78%). Successful delivery was noted in 35 patients (46%). Eight patients (11%) elected to undergo abortion for nonmedical reasons. Sixteen patients (21%) sustained fetal loss, and 17 patients (22%) were lost to follow-up. The 51 patients who either delivered successfully or experienced a fetal loss were studied to determine the factors that affected fetal outcome. Variables analyzed included gestational age and maternal age, Glasgow Coma Scale score, serum bicarbonate level, pH, PCO2, PO2, blood pressure, heart rate, Injury Severity Score, and performance of surgery or diagnostic peritoneal lavage. Logistic regression analysis revealed that ISS (p less than 0.01) and admission serum bicarbonate level (p less than 0.02) have the most significant correlation with fetal outcome. No other variable exhibited a statistically significant influence on fetal outcome. This information documents that fetal demise is related to severity of maternal injury as characterized by ISS. A low serum bicarbonate level corresponds to maternal hypoperfusion and hypoxia, which may be otherwise unrecognized because of the normal physiologic changes occurring during pregnancy. Based on these findings, routine serum bicarbonate determination in all pregnant patients being evaluated for trauma is advocated. Performance of DPL and surgery do not have a significant association with fetal loss and therefore should not be withheld when indicated in a pregnant patient.
