The huge growth in inductions is very worrying. This study is vitally important.
Induction rates have soared, and many healthy women are offered induction without good medical reason.
A new study has “compared intrapartum interventions and outcomes for mothers, neonates and children up to 16 years, for induction of labour (IOL) versus spontaneous labour onset in uncomplicated term pregnancies with live births.”
The results show that induction of labour leads to more intervention and more adverse maternal, neonatal and child outcomes. Although the induction rate has tripled in some groups in the past 16 years, there has been no reduction in stillbirth.
The researchers found that, “Women with uncomplicated pregnancies who had their labour induced had higher rates of epidural/spinal analgesia, CS (except for multiparous women induced at between 37 and 40 weeks gestation), instrumental birth, episiotomy and PPH than women with a similar risk profile who went into labour spontaneously.
“Between birth and 16 years of age, and controlled for year of birth, their children had higher odds of birth asphyxia, birth trauma, respiratory disorders, major resuscitation at birth and hospitalisation for infection.
“In this study, only hospital admissions were examined and hence more serious illnesses. Though this risk varied by gestational age of labour onset, there was no gestational age for which any of these risks were significantly lower for those born after IOL when compared with those born after spontaneous labour onset.” (Dahlen et al 2021)
The researchers conclude that, “IOL for non-medical reasons was associated with higher birth interventions, particularly in primiparous women, and more adverse maternal, neonatal and child outcomes for most variables assessed.” (Dahlen et al 2021).
