Author Question: Motorcycle Injuries

Tory Asks:

I’m currently writing a fan fiction and the two main characters get in a motorcycle crash. The female just found out she was pregnant. I have three (very unrelated) questions. Could the crash send her into cardiac arrest? Would the male (who was driving) be able to survive with just a broken arm and a sprained ankle? And would the baby survive?

Jordyn Says:

Hi, Tory. Thanks for sending me your questions.

1. Yes, a motorcycle crash could send someone into cardiac arrest.

2. Could the male survive with just a broken arm and a sprained ankle? Sure, this is possible, but I don’t know if it’s probable. When looking at accidents, medical people always look at the injuries of the other people involved to determine how serious everyone’s injuries might be.

If the female in the accident suffers a cardiac arrest, it would be surprising that the male walks away with just, essentially, a broken arm. You could make it more believable in the description of how the accident happens. For instance, the female is thrown from the bike, but the male is trapped underneath it. You could also have them differ in the type of protective equipment they’re wearing (helmet, jackets, etc.)

3. Would the baby survive? Again, it depends on a lot of factors. How far along is she in the pregnancy? Cardiac arrest— how long is she pulseless? What other injuries does she get in the accident? The sicker she is from her injuries, the more likely she will miscarry the pregnancy. The body will defer energy and resources to the mother over the pregnancy. Then again, some women have maintained a pregnancy through terrible injuries so you would have some leeway as an author here.

If the mother is far along in the pregnancy (at least 22-24 weeks along) and in cardiac arrest the providers might consider C-section to save the infant. So, without more details as to the nature of the accident, her injures and the state of her pregnancy, it would be hard to say if the baby would likely live or die.

Good luck with your story!

Forensic Question: Testing a Blood Sample for Pregnancy

Jordyn Asks:

Can you test a blood sample to see if the person who left the blood behind is pregnant?

Amryn Says:

For most traditional tests, it would require a fair amount of blood be left behind in order for perform a pregnancy test. The blood would also need to still be in liquid form rather than dried.

It’s not something that would be done for a variety of reasons, not the least of which is that samples are usually conserved as much as possible for forensic testing. So while it’s possible with the right set of circumstances, it likely wouldn’t be done since the blood would be used for DNA testing rather than diagnostic testing.

Zika Update

On November 6th, 2016, 60 Minutes did a piece on the current state of Zika infection that I found quite intriguing. A runaway infectious virus is always good fodder for a novel, but as a healthcare provider I also feel there is a public teaching component so this blog piece serves as both. What follows is taken directly from this 60 Minutes piece and I highly encourage you to watch it.

Currently, there are 30,000 diagnosed Zika cases in the United States. It is present in every state but Alaska. Most of these cases are in Puerto Rico. Of these cases, there are approximately 1000 pregnant women in the US with the virus mostly obtained from travel. Of these pregnancies, twenty-five were born with birth defects and five ended with loss of the baby.

Zika has now been identified to be transmitted three ways: mosquito bite, blood, and sex (the very first mosquito born virus to be transmitted this way.)

Zika was first discovered in Africa in 1947 where it caused regional infections for sixty years. In 2007, it popped up in the Pacific Islands which became its launching point for worldwide infection because infected people traveled from there globally.

The infection stays in the bloodstream for approximately one week. What makes that problematic is the person can be infectious but asymptomatic. People tend to be less precautious when they think they aren’t sick.

Currently, the largest concern is infection among pregnant women where Zika has been positively linked with microcephaly– a severe brain birth defect. Infection in the first trimester is most critical though Zika has been shown to cause birth defects regardless of how far the mother is along in her pregnancy. In addition to microcephaly, Zika can cause seizures, difficulty swallowing, retinal damage which could lead to blindness, and hearing loss.

Zika infection causes a range of symptoms— the most common is what feels like the flu. However, a small number of patients go on to suffer more complicating neurological problems such as inflammation of the spinal cord and Guillain-Barre syndrome.

There is a vaccine in early clinical trials. If the vaccine proves successful, it could be available in early 2018.

Many doctors encourage women to delay pregnancy until a vaccine is available— particularly if living or traveling to a region where populations of the Aedes mosquito infected with Zika are high. If pregnant and in an area where Zika is present then good mosquito control measures.

What are your thoughts on Zika? Would you get a Zika vaccine if available?
