Abstract:
:A brief review of the evidence for and against the 12-week gestational age limit for abortion by curettage is reported. Existing data suggest that second trimester evacuation abortion is associated with higher morbidity and mortality rates than first trimester suction curettage, but with lower rates than second trimester instillation procedures. It is suggested that randomized studies may be needed to establish a more appropriate gestational age limit, if a limit is necessary, for instrumental abortion.
