The incidence of somatic complications in connection with legal termination of pregnancy by vacuum aspiration was analysed in 1,123 hospital patients. Special attention was paid to complication rates in relation to gestational age. It was found that the incidence of major uterine haemorrhage increased with gestational period, being unexpectedly high in the 12th week. When anaesthesia was supplemented with halothane there was a significantly higher incidence of uterine haemorrhage that when this anaesthetic was avoided. The results indicate that strict principles for the operation procedure are mandatory to reduce blood loss and other complications. It is suggested that the end of the 12th week should not be considered as a "magic" time limit for vaccum aspiration but that the policy should aim at early intervention, preferably before the end of the 10th week. In the event of late first trimester abortions or "border line" cases it is of advantage to administer prostaglandin extra-amniotically for pre-operative dilatation of the cervix.
对1123例住院患者进行了分析，以研究与真空吸引法合法终止妊娠相关的躯体并发症发生率。特别关注了并发症发生率与孕周的关系。结果发现，主要子宫出血的发生率随孕周增加而升高，在第12周时意外地高。当麻醉中添加氟烷时，子宫出血的发生率明显高于避免使用这种麻醉剂时。结果表明，严格的手术操作原则对于减少失血和其他并发症是必不可少的。建议不应将第12周结束视为真空吸引的“神奇”时限，而政策应旨在早期干预，最好在第10周结束前。对于孕早期晚期流产或“临界”病例，在术前经羊膜外给予前列腺素以扩张宫颈是有益的。
