Balancing the risks of prolonged gestation against those of induced labour is difficult. Risks to the fetus increase slightly after 42 weeks' gestation but women having labour induced are more likely to have instrumental deliveries or babies with low Apgar scores. Since many women are now expressing a preference for minimal interference in childbirth the most acceptable management of post-term pregnancy seems to be increased fetal surveillance. Each case needs to be considered individually and it is important that the woman is involved in the decision to induce.
平衡过期妊娠的风险与引产的风险并非易事。妊娠42周后,胎儿风险略有增加,但引产的女性更有可能接受器械助产或产出阿氏评分低的婴儿。由于现在许多女性倾向于在分娩时尽量减少干预,因此对于过期妊娠,最可接受的管理方式似乎是加强胎儿监测。每个病例都需要单独考虑,让女性参与引产决策非常重要。
