Introduction

Induction of labour (IOL) is the process of artificially stimulating the uterus to begin labour. Cervical ripening (the process of softening, effacing and dilating the cervix) is often required prior to IOL. IOL is recommended when the maternal and/or fetal risks of ongoing pregnancy outweigh the risks of IOL and birth. The purpose of this guideline is to guide the IOL process for women at or near term. Refer to associated Queensland Clinical Guidelines for specific circumstances outside the scope of this guideline including: 

 • Early pregnancy loss

 • Termination of pregnancy

 • Perinatal care of the extremely preterm baby

 • Preterm prelabour rupture of membranes

 • Term prelabour rupture of membranes

 • Stillbirth care

 • Vaginal birth after caesarean

引言
引产术（IOL）是指通过人工方式刺激子宫启动分娩的过程。引产前常需进行宫颈成熟化处理（即软化宫颈、促宫颈消退和扩张的过程）。当继续妊娠对母体和/或胎儿的风险超过引产及分娩风险时，建议实施引产术。本指南旨在为足月或近足月产妇的引产流程提供指导。若涉及本指南范围外的特殊情形，请参阅昆士兰相关临床指南：

• 早期妊娠流失
• 妊娠终止
• 极早产儿围产期照护
• 早产胎膜早破
• 足月产前胎膜早破
• 死产护理
• 剖宫产后阴道分娩
