As with any medical intervention performed during pregnancy, expectant mothers are concerned about the possibility of undergoing surgery or other medical procedures that require anesthesia and may not be safe when pregnant. Naturally, there is concern for the development of the fetus, as well as for the immediate safety of the pregnancy and the safety of the mother. Recent studies and a long history of documented use have repeatedly shown that anesthesia is generally safe when pregnant.

With studies that involve the use of anesthesia during pregnancy, it is difficult to attribute complications or malformations in a pregnancy to anesthesia. It is often unclear what specifically may not have been safe when pregnant and what may have caused the complication. Was there a preexisting and undiagnosed condition, or was the complication caused by the stress or trauma of surgery? Many risks to the fetus during surgery are unrelated to anesthetics, but rather due to the mother’s reaction to the surgery.

The need for surgery arises in approximately 1.5% to 2% of pregnancies. This translates to about 75,000 pregnant American women who need surgery every year. This statistic refers to “nonobstetric” surgery, or surgery that is not related to delivery. This includes dental work, ovarian cystectomies and appendectomies, among many others. The number one cause of maternal death is trauma to the mother, and the need for emergency, nonobstetric surgery is often due to unexpected trauma.

The four main concerns of an anesthesiologist caring for a pregnant woman in surgery are physical reactions relating to the respiratory, cardiovascular, gastrointestinal and central nervous systems. Above all, blood and oxygen flow must be maintained to both the mother and the fetus in order for surgery to be safe when pregnant. If the mother experiences a drop in blood pressure or oxygen saturation, this is cause for concern for the safety of the fetus. Although concerns have been raised in the past about whether the use of nitrous oxide and benzodiazepines is safe when pregnant, no recent study has found any increased risk of congenital abnormalities or preterm labor. Doctors generally agree that inhaled and intravenous anesthetics and narcotics have a long history of being safe when pregnant.

One of the main concerns that doctors and anesthesiologists have when operating on a pregnant woman is preterm labor. For this reason, pregnant women are advised to put off any surgery that can wait until the second or third trimester, preferably the third trimester. For doctors and pregnant women who are particularly cautious, regional anesthetics can minimize the exposure of anesthesia to the fetus, and their use is safe when pregnant. However, some surgery requires the use of general anesthesia. Women who worry whether surgery and anesthesia are safe when pregnant may wish to consult their obstetrician, surgeon and anesthesiologist for peace of mind.

Please help. My daughter is six weeks pregnant and a second baby was in her fallopian tube, and with an emergency pregnancy under anesthesia, what are the risk to the baby she still has at six weeks?

@anon81563: I just found out I have the same problem! My doctor wants me to schedule surgery during my second trimester. Did you have the surgery? How did everything go for you and the baby?

@anon248166: If you're in a reputable hospital, yes. I had minor outpatient surgery last year, and even though I could categorically state without the slightest doubt that I was under no circumstances pregnant, they still did the test. It's the only pregnancy test I've ever had done.

Because you can't count on a patient being absolutely truthful (or she may not know, yet), any anesthesiologist worth the parchment his/her diploma is printed on will order a pregnancy test before surgery.

I want to be an anesthesiologist when I grow up, but I also want to have kids. Being around the anesthesia won't affect the fetus, right?

I am about four weeks pregnant and just found out a few days ago due to me having to get medical clearance in order for me to have surgery the following week in order to fix a broken cheek bone. I was told I'm going to be under general anesthesia. Now I am worried about my child. What are my risks?

I found out that I need brain surgery, but I also found out that I am 13 weeks pregnant. I have a history of slowed heart rate and low blood pressure from surgery. I've been trying to have a baby for so many years, but now that my life is on the line from my brain condition, I'm worried that it's going to come down to one of us dying.

I'm six weeks pregnant and have breast implants,i recently found a large lump under my arm and after seeing a specialist have been told i have silicone in my lymph gland, which shows my implant has a rupture and needs changing.

i am worried for myself about the effects of the silicone as it's said it can travel to other parts of the body and i am frightened that it will make me ill.

i can wait until after the baby is due but worry the damage i am doing to my body.

My wife is going to need a surgery to remove two metal plates from her arm (she broke it last summer and the plates come out in December). if she has to have the surgery and is three months pregnant, is there a danger to baby and mother with anesthesia needed for the surgery?

I'm 18 weeks pregnant and i've just had a biopsy on a lump i have which the surgeons tried to remove.

i had local anesthetic, I'm fine as far as my pregnancy goes. I think that different surgeries affect different people in different ways.

Please, most of you should be fine and a local anesthetic should really have no effect on your unborn.

I am 13 weeks pregnant and have to undergo an ICD operation on my heart. I was told that the best time to have surgery is in the second trimester. although the anesthesia can cause you to go into labor and hence miscarry if you are early on in the pregnancy. It's tough to think about but weigh out what is more important.

if you can hold off the surgery i strongly recommend it but everyone's situation is different so the doctor or anesthesiologist would be the best person to ask!

I was given anesthesia for a surgery not knowing that I was pregnant. I found out I was pregnant upon waking up from surgery. Apparently my urine test was negative but when my blood was tested during the surgery, it was positive. I was informed upon waking that I was pregnant. I found out later that I was probably only 5 days pregnant at the time of the surgery. About 5-6 weeks later, I had a miscarriage. Is it possible that the anesthesia that I was given so early in the pregnancy have caused the miscarriage to happen?

I am 7 weeks and 5 days pregnant and had Laproscopic excision of endometreosis and a hystercopy 3 weeks ago. We did not know that we were pregnant until yesterday. I am concerned that with such surgery i have put the baby at great risk. The fact that i had an anaesthetic and then was using Tremol and Vultaren for two weeks after the surgery scares me too. What are the risks? What questions do i need to ask my specialist/surgeon? Can you detect any damage?

It is my understanding that waiting, until the first trimester is over, is advisable (at least 14-16 weeks). Then, the pregnancy (baby) is a bit more stable. Also, if it's elective surgery, then definitely wait.

I have currently found out that i am 7 weeks and 4 days pregnant. I was scheduled to have a breast reduction due to bad back and neck pain. Is it safe to continue with the surgery even though i'm pregnant? And will the anesthesia affect my baby?
