Term: Induction of Labour
Last Updated: 2012-11-05
Labour Induction is the act of stimulating labour contractions to begin the birthing process, through either physical or medical means. Physical methods of induction include the artificial rupture of the membranes to break the water. Medical methods include the intravenous administration of the chemical oxytocin to initiate labour. Note that induction of labour is akin to the term
augmentation of labour
in method, but induction is only carried out before the onset of labour.
In Martens et al. (2008), induction of labour included only medical induction, defined by ICD-9-CM procedure code 73.4 (medical induction of labour) in any procedure field on an obstetrical hospital discharge abstract.
