Some pregnant women avoid vehicle driving owing to the risk of contact between their protruding abdomen and steering wheel. This study was performed to determine whether abdominal protrusion in late-term pregnant car users affects the occurrence and severity of abdominal injuries in motor vehicle collisions using a national crash database.
The National Automotive Sampling System/Crashworthiness Data System was used to analyse maternal background, collision characteristics, outcome and Abbreviated Injury Scale (AIS) scores for the body regions of all persons involved in the collision.
Comparison of pregnant and non-pregnant women in the driver's seat showed no significant differences in the rate of AIS scores of ≥2 (2+) for abdominal injuries and female outcomes. Comparison of use of the driver's seat and front passenger's seat by pregnant women showed no significant difference in rate of AIS 2+ injuries or in maternal and fetal outcomes. Comparison of pregnant women with a gestational age of ≤27 and >27 weeks in the driver's seat showed no significant differences in rate of AIS 2+ injuries or in maternal and fetal outcomes.
Based on the data from relatively low-speed frontal collisions, obstetrician/gynaecologists should advise pregnant women that they do not need to change their preferred car seat from the driver's seat to another seat because of fear of contact between their protruding abdomen and the vehicle interior.
一些孕妇因腹部隆起可能与方向盘接触而避免驾车。本研究旨在利用国家碰撞数据库确定晚期妊娠汽车使用者的腹部隆起是否会影响机动车碰撞中腹部损伤的发生及严重程度。
使用国家汽车抽样系统/碰撞耐撞性数据系统分析碰撞中所有人员的孕产妇背景、碰撞特征、结局及身体各部位的简略损伤量表（AIS）评分。
对驾驶座上的孕妇和非孕妇进行比较，腹部损伤AIS评分≥2（2+）的发生率及女性结局方面无显著差异。对孕妇使用驾驶座和前排乘客座的情况进行比较，AIS 2+损伤发生率以及母婴结局方面无显著差异。对驾驶座上孕周≤27周和>27周的孕妇进行比较，AIS 2+损伤发生率以及母婴结局方面无显著差异。
基于相对低速正面碰撞的数据，妇产科医生应建议孕妇，无需因担心腹部隆起与车内物体接触而将首选的驾驶座更换为其他座位。
