o Gestational age should be confirmed by clinical evaluation or ultrasound
o Before ultrasound is undertaken, women should be asked whether they would wish to see the image or not - Prevention of infectious complications
o Antibiotics
. Surgical abortion: universal use is effective
. Medical abortion: controversial
o Antibiotic choice should take into account the local epidemiology of genital tract infections, including sexually transmitted infections.
o If bacterial vaginosis or a sexually transmitted disease is identified preoperatively, treatment should be administered according to CDC sexually
transmitted disease treatment guidelines
