Classification of caesarean section in labour.
| Foetal distress (no oxytocin) | ||
|---|---|---|
| Inefficient uterine action (cervical dilatation <1 cm/h) | Poor response (maximum dose reached) * | |
| Inability to reach maximum dose due to foetal intolerance | ||
| Inability to reach maximum dose because of over-contracting or not following unit protocol | ||
| Efficient uterine action (cervical dilatation >1cm/h) | Cephalopelvic disproportion | |
| Malposition (e.g. occipito posterior) | ||
Maternal and neonatal outcomes (corrected for lethal congenital malformations) in Group 1 (Robson’s Ten Group Classification System – nulliparous women with spontaneous onset of labour at ≥37 weeks with single cephalic foetuses) in 14 maternity units in Slovenia in years 2013 and 2014.
