Is it safe for baby at 23 wks pregnant for me to be in car mechanics place for about an hour smelling fumes, looking at what was wrong with my car?

Avoid exposure: It's impossible to do control studies in that situation so I would do everything I could to avoid exposure to any chemicals you can avoid.

Yes: There shouldn't be a problem if the garage was ventilated, and you are not having significant symptoms.

No: If there are fumes that the baby is getting through you i don't think it is good. Check with your OB and I thinks he will agree

Ris: Risk exists. Auto shop fumes are mixed but carbon monoxide and incomplete combustion fumes are unhealthy.

Should : Not be an issue. Short exposure time and limited fumes should not have any effects.

It depends: One might encounter a problem if they are doing body shop work (painting) in the immediate area. Exhaust fumes are unavoidable if one lives in a city. The idea is to minimize stress and chemical exposure to mother (and by proxy the baby) . It must be stressful to have car problems in the second trimester of a pregnancy. If you were not physically ill from the exposure to fumes that is reassuring.

Car fumes not good: anyone especially a pregnant lady should not be exposed to fumes from a car...the carbon monoxide emitted from cars can be dangerous if you are exposed to it for long periods or in concentrated doses. I would take a walk and not spend any significant time in a confined space with cars that have engines running

You should be ok: Most auto mechanics have a well ventilated shop (they are required to by OSHA) and the likelihood of any injury to your fetus from such a small amount of time is extremely small. First pregnancy?

Once prob no effect: I am not a pediatrician or an obstetrician, my opinion is just that (talk to ur family doc). While it is not advisable to habitually hang around any industrial site (until after you've delivered), just 1 hr at a mechanic's shop won't do much. Did you have any symptoms (headaches, nausea, etc.)? The 1 concern is carbon monoxide, which has an affinity for fetus. Stay away from smoke (& cig smoking)!

Best to avoid fumes: It is best for all humans to avoid unnecessary exposure to exhaust fumes, but baby is protected by Mom's filtering systems. Also, most birth defects occur much earlier in development. Mom's airways filter out some pollutants, then the lungs trap further impurities as the oxygen crosses into the blood. The placenta then further filters the blood before it goes to baby.

Ok : There should not be any gas that would cause any problems,

Not Really: It certainly would be advisable to avoid inhalation of fumes during pregnancy.

Fumes: I think it is important to just be as normal as possible .. You can not live in a bubble try to live a normal life and avoid as much toxic exposure as possible

Fumes: A one time episode is unlikely to be harmful, but I would not make a regular habit out of it.

Hazardous chemicals: I don't think your behavior is healthy, but rating the amount if harm to your 23 week fetus is difficult to gauge. As a rule, I tell my patients that if you have any reason to believe what you're doing is unhealthy, it's a bad idea to do it while pregnant, at any week of gestation . The earlier in pregnancy, the greater the harm is to your baby, if the exposure is harmful in the first place

Stay in waiting room: It would be best to stay in the waiting room away from the fumes, but also away from the work area, which could be hazardous.

It ok: You inhale car fumes al the time unknowingly. Car fumes are not known to be teratogenic

Realtively safe: not totally safe but if happened, no immediate harm expected, please avoid similar situation as much as possible

Fumes: It is probably best for you to not be in the middle of the fumes. Is the mechanic that you took the car to going to do the repairs? Do you trust them? If you do indeed trust them is it necessary to see first hand what needs to be repaired? Waiting room is a good place to wait for the repairs to be done. Besides, gives you a chance for some down time.

Exposure to fumes: At 23 weeks, the fetus is formed and protected from inhalation of fumes. Your lungs filter out the fumes and unless you have experienced some symptoms yourself, it is very unlikely your baby has. Make sure you are well hydrated so any chemical byproducts can be more easily excreted through the urine. Your exposure to fumes is minimal as compared to the folks who work there.

Exposure to fumes: most likely your baby is safe and will not have any long term affect or complications as a result of such exposure.
