Study summary

Maternal hypotension is a common problem during cesarian section under spinal anesthesia. The possible explanation for this is combined aortocaval compression by gravid uterus in parturient in addition to reduced systemic vascular resistance by spinal anesthesia. The investigators evaluated if the incidence of hypotension would be decreased by delayed supine positioning, by maintaining lateral position for 6 min after spinal injection, in patients undergoing elective cesarean section.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 12, 2010, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
