Does the anesthesia affect on fetus?my wife did an operation for bartholin's abscess.

Doubtful: Depends on the type. Having said that, both local and general anesthesia are very safe, and unlikely to cause problems with the baby. Just like everything however, there are no absolutes. See your OB doc for more info.

Rarely: Most of the time there is no effect.

Anesthesia : Yes...It depends what was used however. She really could have had the whole thing done under local anesthesia probably which has minimal risk.

Variable: This depends on the age of the fetus. Talk to your anesthesiologist to discuss your wife's case.
