Trauma in pregnancy: A review of the Pennsylvania Trauma Systems Foundation database

Objective: The goal of this study is to determine if injury severity score (ISS) of ≥9 and systolic blood pressure (SBP) predict poor maternal/pregnancy outcomes in blunt and penetrating trauma, respectively. Methods: The Pennsylvania Trauma Systems Foundation database was used to identify pregnant trauma patients. Blunt trauma patients were analyzed with regard to ISS, while penetrating trauma patients were analyzed to determine whether SBP < 90 mmHg was predictive of poor maternal outcome. Results: Patients with severe blunt injury (ISS ≥ 9) due to motor vehicle accident were less likely to wear seatbelts (51% vs. 63%, p = 0.005), and delivery was required in 17% of these patients as compared to 6% of the less severely injured, and only 6% of those were vaginal deliveries. Severely injured patients were discharged home 68% of the time and 6% died compared to less severely injured patients of which 83% were discharged home and <1% died; all other patients required discharge to a rehabilitation facility. Patients with penetrating trauma and SBP < 90 mmHg on arrival were more likely to require delivery (35% vs. 5%, p < 0.001) and were 14 times more likely to die (58% vs. 4%, p < 0.001) when compared to the normotensive group. Conclusion: ISS ≥ 9 and SBP < 90 mmHg are predictors for poor outcomes after trauma during pregnancy. Severely injured blunt trauma patients often require surgery and delivery. Patients who present with SBP < 90 after penetrating trauma are more likely to deliver and are 14 times more likely to die.
