Missing Stage in Child Passenger Safety — Pregnancy - Safe Ride 4 Kids

Missing Stage in Child Passenger Safety — Pregnancy

child passenger safety — pregnancy

“The major role that motor vehicle injuries have on reported traumatic fetal injury deaths was shown and a significant new challenge for child passenger safety advocates is indicated.” – Professor Hank Weiss concludes in his 2001 study about pregnancy, car crashes and fetal deaths.

Wow! But that was way back in 2001. Surely more awareness has spread or something has been improved.

Have you heard more about protecting expecting mothers and their babies in the car? No?

Until, that is, I went in search of studies and statistics.

We went in search of these studies after we were introduced to the Tummy Shield. At first, after anguishing about the seat belt during three pregnancies, it just made sense. After reading the studies about driving and pregnancy, we knew we had to add it to our collection of innovative products.

And all of our research is why we talk about the 4+ stages of child passenger safety, covering pregnancy as the “plus” stage.

What made Hank Weiss, professor at the University of Otago in New Zealand who studied the risks posed to pregnant women and fetuses by crashes for more than 20 years, say driving during pregnancy is a new challenge for child passenger safety advocates? Isn’t driving while pregnant just like driving while not pregnant?

Actually, no.

Generally speaking women wear their seat belt more regularly than men, but that drops off dramatically during pregnancy (Attico et al 1986).

This is not good since unbelted women are 2.8 times more likely to lose their baby in a car crash (Hyde et al 2003).

Reasons pregnant women often don’t wear seat belts:

  • seat belt was uncomfortable,
  • shoulder strap too tight across breasts,
  • lap belt tended to slide up over abdomen,
  • lap belt too tight or short,
  • fear the fetus would be harmed (Cesario 2007).

When an estimated 3,000 otherwise healthy unborn babies are lost every year (about 8 a day) as a result of car crashes (based on ranges in Klinich et al 1999; Pearlman 1997), there’s already an increased risk when driving while pregnant. (And that estimate only counts pregnancies lost that were more than 20 weeks gestation!)

“The magnitude of the problem is likely far greater than the numbers show,” Weiss told a reporter for the Atlantic City Lab in 2013, “because many cases – especially those involving early pregnancy – are not recorded in a way that is accessible to researchers.”

Even if they do wear a seat belt.

No one leaves the house thinking they’ll be in a crash that day. Yet it happens. Every. Day.

Pregnant women are just as susceptible as any other person. A University of Michigan study showed 170,000 crashes a year involve a pregnant woman. Of those 116,000 report some sort of injury.

In the first trimester, the uterus is still low in the abdomen and surrounded by the pelvis. In the second and third trimesters, it grows upward and outward, losing the protection of the pelvic ring and displacing other abdominal organs. Researchers Greg Friese and Randal Wojciehoski add, at this point around 12 weeks the uterus is now more susceptible to injury.

Their 2005 study estimated that 1,500 to 5,000 fetal deaths each year result from maternal involvement in motor vehicle crashes. And those statistics do not include uncounted adverse outcomes from motor vehicle collisions, like possible life-long disabilities from injuries or complications from an emergency delivery.

Common fatal outcome

Placental abruption is most frequent cause of fetal death after car crash. Cases of abruption within five days of crash have been reported. Sometimes a loss can be a couple weeks after a crash and doctors do not connect the two.

Placental abruption occurs in 1 to 5% of crashes considered of minor severity during pregnancy and from 20 to 50% of severe crashes during pregnancy. Some placental abruptions may result from high-velocity, low-mass airbag loading, or from compression between the mother’s body and the steering wheel, seat belt, or instrument panel. (Klinich et al, 1998)

“While these results show that placental injuries can occur to properly belted pregnant occupants, they also show that avoiding belt use during pregnancy may significantly increase the risk of placental abruption and subsequent fetal loss in a crash,” Klinich’s study said.

Common injury

Head trauma is the most common direct fetal injury, especially in later terms of pregnancy when the head is positioned low. Friese and Wojciehoski believe head trauma results from the baby being compressed between the maternal pelvic bones and the seat belt, steering wheel or dash.

We have years under our belts as child passenger safety technicians and Greg has experience as a paramedic. We know the seat belt is the first line of defense. It is designed to hold the occupant in place in their seat so they do not hit the steering wheel or dash.

In our friend, Taylor’s, experience when she lost her baby to direct head trauma during her 8th month of pregnancy, she was sitting in the passenger side properly wearing her seat belt as low as possible on her hips and did not come in contact with the dash. As a matter of fact, the only visible injury she had was a bruise on her low abdomen where she was correctly wearing her seat belt.

What do experts suggest?

Many of the studies recommend health care providers counsel pregnant women more about the risks of driving during pregnancy. They need to emphasize the importance of wearing their seat belt. On average, only 48.7% of care providers reported counseling for seat belt use during prenatal visits. And of those only 27% of the women remembered the counseling. (Weiss et al, 2007)

Getting all healthcare providers sharing information in a more memorable way is a first step. We suggest the information come from multiple sources like pregnancy books, magazines, and — as Weiss suggests — child passenger safety technicians.

Pregnant women should:

  • always wear a seat belt correctly (low and snug over the hips);Tummy Shield safest pregnacy seat belt adjuster
    • We believe the Tummy Shield offers optimum protection by safely redirecting the seat belt away from the belly, creating a leg harness like a race car driver.
  • keep airbags activated but make sure to direct it toward the chest area instead of straight out;
  • avoid driving at night or in bad weather, when the risk of a crash is highest;
  • drive on roads with lower speeds, because low-speed crashes are exponentially less traumatic than high-speed ones;
  • simply try to drive and ride in cars less, have others run errands or take public transportation, if possible.

Women go to great lengths in order to reduce risk to their developing children in other ways. Would it really be such a stretch to add precautions for safer driving during pregnancy?
