Hi Marie

Thanks for your question and congratulations on the pregnancy!

First you are not alone, up to 2% of all pregnant women require surgery for all manner of conditions unrelated to their pregnancy, e.g. appendicits, broken bones, etc, etc, (Ne Mhuireachtaigh 2006). Surgeons perform these non-obstetrical operations upon pregnant women only for serious conditions threatening the life of the mother, or conditions causing serious disability if not performed at that moment. The normal policy is to wait until after delivery of the baby before performing any non-urgent surgery.

Studies of the babies of the more than ten thousand pregnant women who underwent anesthesia and surgery reveal that the chance of these women delivering a baby with a birth defect varies between 2-3.9% (Cohen-Kerem 2005, Duncan 1986), which is comparable to the normal chance of delivering a baby with a birth defect. The chance of miscarriage or fetal death as a result of anesthesia and surgery is about 5.8% when averaged over all pregnancy trimesters, but is about 10.5% when anesthesia and surgery occur during the first trimester which is why they are waiting till you are 15 weeks placing you in the second trimester.

Essentially anesthesia and surgery during pregnancy is safe for the mother, and the chance of delivering a baby with a birth defect is unchanged by anesthesia and surgery with the exception of the 1st trimester.

I hope this helps!
