A comparison of D &amp; C and vacuum aspiration for performing first trimester abortion.
In a study of techniques for first trimester abortion conducted at Kandang Kerbau Hospital in Singapore from September 1973 to April 1975, 420 physically healthy gravidas were randomly assigned to one of two treatment groups either by D &amp; C or vacuum aspiration. Half of the patients in each group were 6 to 10 menstrual weeks' gestation and half were 11 to 12 week's gestation. The numbers of women with one or more complications were the same for the two treatment groups, but were significantly less when termination was carried out at 11 to 12 weeks' gestation. Estimated blood loss was significantly lower for patients treated by VA (32.3 ml) than for patients treated by D &amp; C (39.0 ml) at 6 to 10 week's gestation, but the difference in blood loss was not statistically significant at 11 to 12 weeks' gestation. Time from insertion to removal of the speculum was significantly less with VA than D &amp; C at 6 to 10 weeks' gestation but not at 11 to 12 weeks' gestation. Since vacuum aspiration is at least as safe as D &amp; C, and appears to be more convenient and costeffective, it should on the basis of this experience be accepted over D &amp; C as the standard method for treatment of first trimester abortion.
