Acceptability of manual versus electric aspiration for first trimester abortion: a randomized trial

This study was conducted to compare the acceptability of manual and electric vacuum aspiration for first trimester elective abortion. Eighty-four women seeking abortions at less than 10 weeks gestation were randomized to abortion by manual or electric vacuum aspiration. Post-procedure questionnaires were administered to patients to assess pain, noise disturbance and overall satisfaction with the abortion procedure. Physicians reported procedural difficulty, their perceptions of patient discomfort and their overall acceptance of the procedure. Other outcomes included amounts of anesthesia required and complication rates. There were no significant differences in pain levels or satisfaction reported by patients; however, significantly more women in the electric group were bothered by noise (19% vs. 2%, p = 0.03). There were no differences in physician assessments of procedural difficulty; however, there were significantly more times in the electric group that physicians would have preferred manual aspiration (43% vs. 17%, p = 0.02). There were four crossovers from manual to electric, and none from electric to manual. It is concluded that physicians and patients find manual vacuum aspiration as acceptable as electric vacuum aspiration for elective abortions performed at less than 10 weeks gestation.
