Respiratory Variation Index as a marker of labour pain intensity with epidural analgesia: a pilot exploratory study
Authors' conclusion
Respiratory Variation Index exhibits optimal diagnostic performance for stratifying moderate-to-severe or severe uterine contraction pain
Study context
- Population
- Labouring women with epidural analgesia
- Participants
- 21 women · 137 contraction episodes
- Outcome
- Discrimination of moderate-to-severe from no-to-mild uterine contraction pain (NRS)
Methodological detailspilot exploratory
- Pilot exploratory
