Optimally, this should be accomplished with whole blood: However, in emergency situations when blood is not available or is being readied, rapid intravenous infusions of salt solutions or blood substitutes will still improve placental perfusion significantly (Boba, et al, 1966).…”

The medical care provided to a pregnant trauma patient by a trauma specialist should be supplemented by a careful evaluation of the pregnant woman by an obstetrician. Motor vehicle accidents account for two-thirds of all trauma events during pregnancy, and both blunt abdominal trauma and trauma to the skull are associated with high mortality of the fetus. The severity of the trauma is an important prognostic factor for survival of both mother and fetus. Fetal injury can be caused even by apparently mild forms of maternal trauma. For early diagnosis of an abruptio placentae after blunt trauma to the abdomen, continuous monitoring of the fetal heart rate and uterine contractions is very useful. Monitoring should be continued for at least 4 h, and whenever the frequency of uterine contractions exceeds one per 15 min or tenderness of the abdomen or vaginal bleeding is present, the pregnant trauma patient should be carefully monitored under hospital conditions for at least 24 h. Extensive burns are rarely encountered during pregnancy. There is a direct correlation between the extent of the burns and survival of the fetus. When more 30% of the maternal body surface is affected by burns, fetal mortality exceeds 50%. In the third trimester, when survival chances of the fetus are better than 50%, premature delivery of the fetus should be considered whenever the mother has suffered extensive burns.

“…An ECG should be taken, and vital signs should be measured every 5 min. Volume replacement is insti tuted with lactated Ringer's solution in a 3:1 replacement ratio for maternal blood loss, as it is more effective than dextran in restoring fetal oxygenation [7], It is important to note that increased maternal tolerance to blood loss allows the woman to maintain a normal blood pressure despite a 30-35% decrease in blood volume [4,8], At this time, the fetal heart should be monitored, either electronically or by Dopp ler. As the main causes of fetal distress in this setting are maternal shock, abruptio pla centa, and uterine rupture, these potential complications must be investigated and either promptly treated or excluded [10,16].…”

The incidence of motor vehicle accidents resulting in trauma in pregnant women is increasing. The best chance for fetal survival is to ensure maternal survival, so awareness of the types of injuries and their presentation after vehicular trauma is of the utmost importance. An algorithm for the approach to diagnosis and fetal therapy based upon obstetrics and trauma care parameters is hereby presented to the trauma team.
