Objective:
The aim of this study was to understand the injury mechanisms of pregnant drivers and associated fetal outcomes.
Study Design:
Frontal and rear impact tests using a dummy representing the anthropometry of a pregnant woman were conducted.
Results:
In frontal impact tests without a seat belt, abdominal pressure peaked at the point where the dummy contacted the steering wheel. Rear impact tests without a seat belt showed that the dummy moved forward because of rebound and contacted the steering wheel, which was avoided when a seat belt was worn.
Conclusion:
Wearing a seat belt reduces abdominal pressure or prevents contact with the steering wheel during collisions.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...
