Association between intrapartum fetal head malrotation and motor block by neuraxial analgesia: A randomized trial
Not Applicable
Completed
- Conditions
- Singletons in low-risk term deliveries proceeding in the vertex position
- Registration Number
- JPRN-UMIN000011664
- Lead Sponsor
- Kitasato University Hospital
- Brief Summary
The incidence of intrapartum fetal head malrotation was not affected by neuraxial analgesia or the degree of lower extremity relaxation. For obstetric factors, known fetal head malrotation at the start of analgesia and early artificial rupture of membranes at an early stage of labor in primiparas may be associated with intrapartum malrotation.
