R. Towery et al., EVALUATION OF PREGNANT-WOMEN AFTER BLUNT INJURY, The journal of trauma, injury, infection, and critical care, 35(5), 1993, pp. 731-736
A retrospective review of 125 pregnant women with blunt injuries admit
ted to a level I trauma center over a 35-month period was performed. T
he usefulness of three diagnostic tests, fetal ultrasound (US), extern
al fetal monitoring (EFM), and Kleihauer-Betke (KB) tests in detecting
fetal or pregnancy-associated complications was evaluated. The majori
ty of women (77.6%) were involved in motor vehicle crashes and the mea
n Injury Severity Score was low (4.7). The most common complications w
ere premature uterine contractions (67%) and abruptio placentae (11%).
When used together, EFM and US identified all complications. Moreover
, all complications were manifest within 6 hours of admission. The KB
tests had a sensitivity of 56%, a specificity of 71%, and an accuracy
of 27%. We conclude that EFM and US are more useful in detecting fetal
or pregnancy-associated complications after blunt injury. Monitoring
can be limited to 6 hours if previous monitoring is normal. The KB tes
t is of little use in the seating of acute trauma.
