Re: Lidocaine administered in first trimester

[Guest guest]

If anyone can provide any information on the effects of lidocaine to a

fetus in the first trimester I would be very greatfull. There is not

any difinative information on the internet. The effects are generally

unknown.

I got a thyroid biopsy today. I have had several in the past with out

any pain medication. I am 10 weeks pregnant and it was administered

with out warning. Now I am very concerned with the effects it may

have on my baby.

Thanks,

Hullo . Did you not ask why you were being given lidocaine? Did you/have you/ questioned that doctor or the reason. Did they know your were pregnant? Can you find out HOW MUCH you were given. Was it subcutaneous injection, patch, or what? Was the block used with or without epinephrine? Epinephrine: May be used to decrease systemic absorption of lidocaine/bupivacaine; if used. Need to find these things out and ask some questions! Lidocaine crosses the placenta barrier as well as in breast milk, so it does get around. Animal studies with lidocaine have not shown teratogenic effects. Lidocaine and bupivacaine cross the placenta; effects to the fetus may depend on procedure performed. Use during pregnancy only if the potential benefit to the mother outweighs any potential risk to the fetus. Explanation: Animal studies have revealed no evidence of harm to

the fetus, however, there are no adequate studies in pregnant women OR animal studies have shown an adverse effect, but adequate studies in pregnant women have failed to demonstrate a risk to the fetus. It can be a little scary, as there is little information, as you have said, on effects to the fetus. But I would be asking some Hard Questions! Good luck with everything.

Hi Karla, They knew I was pregnant and said they always administer injections with thyroid biopsies. I have never had one in this hospital so didn't expect it, never having it used in past biopsies. My OB said it was fine, but I felt as though he may be protecting the endocrinologist. I will call back and find out about the epinephrine. Thanks for that tip and the link!On Jan 9, 2009, at 12:22 AM, karla walsh wrote:Hullo . Did you not ask why you were being given lidocaine? Did you/have you/ questioned that doctor or the reason.
