Impact of nitrous oxide use on parturient recall of neuraxial analgesia risks
Authors' conclusion
The use of nitrous oxide for labor analgesia does not adversely influence a parturient's ability to recall the risks of epidural placement.
Study context
- Population
- Nulliparous patients with spontaneous or planned induction of labor, labor and delivery unit of a large academic medical centerenrolled
- Participants
- 403 patients
- Exposure
- Nitrous oxide vs no nitrous oxide during labour
- Nitrous oxiden = 109
- No nitrous oxiden = 294reference
- Outcome
- Recall of epidural risks (unprompted or prompted)
Methodological detailssingle-centre, Nitrous oxide users more often cared for by midwives and had higher pain scores at epidural request
- Single-centre
- Nitrous oxide users more often cared for by midwives and had higher pain scores at epidural request
Main finding
As reported in the abstract
- Scores for unprompted or prompted recall of epidural risks not different between Nitrous oxide and No nitrous oxide
Observational data: associations, not effects.
Further findings
All 4 risks recalled unprompted · Pearson χ2 test
