目的：该项目旨在提高对机动车碰撞事故中孕妇胎儿不良结局相关因素的了解。研究设计：对涉及 57 名孕妇的碰撞事故进行了深入调查。收集了孕产妇和胎儿受伤情况、约束信息、车辆外部和内部损坏情况以及事故情况的详细信息。使用车辆挤压测量来计算碰撞严重程度。使用卡方分析和逻辑回归模型来确定与胎儿结局显着相关的因素。结果：胎儿结局与碰撞严重程度 (P < .001) 和母体伤害 (P < .002) 密切相关。正确使用产妇安全带（带或不带安全气囊）与可接受的胎儿结局相关（比值比 = 4.5，P = .033）。如果所有孕妇正确佩戴安全带，大约一半的机动车碰撞事故中的胎儿死亡是可以避免的。结论：碰撞严重程度越高、产妇受伤越严重以及未正确使用安全带与胎儿不良结局的风险较高相关。这些结果强烈支持孕妇使用正确位置的安全带的建议。
OBJECTIVE: This project was undertaken to improve understanding of factors associated with adverse fetal outcomes of pregnant occupants involved in motor-vehicle crashes.STUDY DESIGN: In-depth investigations of crashes involving 57 pregnant occupants were performed. Maternal and fetal injuries, restraint information, measures of external and internal vehicle damage, and details about the crash circumstances were collected. Crash severity was calculated using vehicle crush measurements. Chi-square analysis and logistic regression models were used to determine factors with a significant association with fetal outcome.RESULTS: Fetal outcome is most strongly associated with crash severity (P < .001) and maternal injury (P < .002). Proper maternal belt-restraint use (with or without airbag deployment) is associated with acceptable fetal outcome (odds ratio = 4.5, P = .033). Approximately half of fetal losses in motor-vehicle crashes could be prevented if all pregnant women properly wore seat belts.CONCLUSION: Higher crash severity, more severe maternal injury, and lack of proper seat belt use are associated with a higher risk of adverse fetal outcome. These results strongly support recommendations that pregnant women use properly positioned seatbelts.
