在妊娠l0周以内做人工流产最为适宜。因为人工流产手术越早就越简单、越安全；反之，手术就复杂，手术后康复时间也就长。
常用的早期人工流产手术有吸宫术(负压吸引术)和钳刮术两种。前者适用于l0周以内的妊娠妇女，后者适用于10一14周的妊娠妇女。妊娠l0周以内子宫不太大；胎儿和胎蛊尚未形成，一般不需要扩张宫颈，很容易将胎块组织吸出；手术中反应轻；出血少，手术时间短，术后休息l一2小时就可以回家，恢复也很快，对身体影响小。
妊娠l0一14周时，因胚胎逐渐长大，胎蛊已经形成，子宫也随着长大，这时做人工流产不宜用简单的吸宫术，而需要采用铂刮人工流产。该手术难度大，出血多，恢复也比较慢，对身体有一定影响。
妊娠超过了14周就不能作上述两种人工流产，而需要住院作引产手术，这样更增加了孕妇的痛苦和手术的危险性。
因此，需要作人工流产的孕妇，应尽量争取在妊娠10周以内作压吸引手术，以减轻流产者的痛苦。
