Introduction of PIEB for maintenance of labour analgesia was associated with reduced incidence of motor block in our institution compared with CEI.

Observational data: associations, not effects.
Further findings
| Outcome | CEI | PIEB | Difference (95% CI) | P value |
|---|---|---|---|---|
| Motor block (subgroup: Robson Group 4a) | 20.3% (interval 16.0%–28.0%) | 12.0% (interval 7.6%–16.4%) | 9.9% (−17.4% to −2.4%) | P = 0.009 |
Caesarean section, operative vaginal delivery, other obstetric outcomes
- No association of PIEB with changes in rates
Other outcomes across Robson Ten Group Classification System (TGCS) (subgroups)
- No significant changes
