title: Safety of local versus general anesthesia for second-trimester dilatation and evacuation abortion.
abstract: In 1980, approximately 100,000 women underwent abortion by dilatation and evacuation between 13 and 24 weeks' gestation; an estimated 500 women experienced serious complications. The comparative safety of local versus general anesthesia for second-trimester dilatation and evacuation is unknown. To compare the serious complications (hemorrhage requiring transfusion, unintended major surgery, and a temperature of greater than or equal to 38 C for greater than three days), 4147 women who received general anesthesia and 5389 women who received local anesthesia at 13 centers in the United States from 1975 to 1978 were studied. Women who had a dilatation and evacuation abortion under general anesthesia had a relative risk of serious complications of 2.6 (95% confidence interval 1.4 to 4.9) compared with women who underwent dilatation and evacuation abortion under local anesthesia. Local anesthesia for second-trimester dilatation and evacuation appears to be both safer and less expensive than general anesthesia.
